Brief Summary of Minutes of Annual Meeting

The annual meeting held in Mississippi State University in 2017 focussed on addressing S1063 objectives, accomplishments, and identifying gaps. To address each objectives of S1063 project in a realistic way, the participants focused their brainstorming information/ideas on measuring the success of practices (structural and non-structural) in maintaining water quality. Watershed-scale modeling has primarily focused on agricultural BMPs using SWAT. The existing models such as SWAT, AnnAGNPS still require many modifications to represent physical processes better. Modifications such as including adding routine to account for overland flow/transport and enhance overall spatial representation were discussed. The participants also reviewed past goals and discussed about how much of those goals have been addressed. All the participants acknowledged that there is an opportunity to make a big contribution in this area from the scientific perspective (both monitoring and modeling) and in outreach and communication with stakeholders.

The group toured multiple types of BMPs that are constructed and monitored various sites within Mississippi State University, Starkville. All the participants agreed to focus on proposal/grant writing in upcoming year(s). Some of the areas for colloaborative proposal included, but not limited to:

• Ephemeral Gully Urban Sediment  
• Safety concerns coupling waste water treatment with on-farm pond water irrigation
• Ecological Ramifications of waste water reuse reduction efficiency
• AnnAGNPS-subroutine development-pond/tailwater
• Regional project- regional P indices
• AGU Special Session Proposal?
• Water use/allocation in water stressed regions/agriculture-irrigation water
• Research coordination network both in monitoring and modeling  
• Urban/rural BMPs comparison of models model integration climate/BMPs evaluation
• Field vs watershed scale evaluation

The group agreed on forming a working group and have a monthly conference call to address important objectives/goals.

The principle focus of this project is to evaluate the effectiveness of best management practices (BMPs) at the watershed scale. This includes the water quality and environmental benefits of mitigation practices as well as their cost effectiveness. This will be achieved through monitoring at sub-watershed scales, modeling at larger spatial scales, and analysis of uncertainty in both monitoring and modeling efforts. his report summarizes the first year of activity on this project and the following sections highlight accomplishments from project teams. 

Objective 1: Monitor water quality from a variety of watersheds with a range of conditions (e.g., differing landuse and associated implemented BMPs, varying geographic/geologic conditions).

Kansas State University (A. Sheshukov); In Northeast Kansas, Kansas state University Team continued data collection on a no-till field that contained 4 well-identified ephemeral gullies. The collection process was based on the photogrammetry approach. Surveying equipment (camera, software, backpack, frame) was either purchased or custom-made in KSU-BAE. The team collected micro-topographic information at 8 survey dates. Weather data (precipitation, temperature) was collected sub-hourly. Data is being processed and analzyed. KSU Team (Dr. Trisha Moore, Dr. Aleksey Sheshukov, Dr. Dan Devlin, Mr. Ron Graber) worked with the City of Wichita on off- site BMP trading program. This program could be adapted by MS4 communities elsewhere as a means of integrating water. 

Mississippi State University (J Czarnecki, J. Paz): MSU team is currently quantifying benefits of BMPs by evaluating performance at discrete points, for example, with ISCO water quality sensors placed on the landscape to sample water at key points. Considering erosion and surface water quality, transferring monitoring capabilities to unmanned aerial vehicle (UAV)-based platforms would allow regulators to monitor larger areas, and provide more data over continuous surfaces. A low-cost, off-the-shelf UAV can quickly and easily gather data necessary to construct 3D models of landscapes. Eroded areas are easy to identify, and areas of loss and deposition are visible. More research is needed to determine the sources and magnitude of error present in 3D surfaces before they can confidently be used in watershed models. OFWS systems have been increasingly implemented in agricultural fields in Mississippi and other farmed regions within the Lower Mississippi River Valley because of their nutrient reduction and water supply benefits. Our study provides important information and seasonal analysis of the discharged water that was monitored over the course of a year (December 22, 2015 to December 21, 2016) and its associated nutrient load, monitored from March 2012 to May 2017.

Purdue University (S. McMillan): Assessment of ecosystem services of urban rain gardens: The goal of this project is to quantify and compare multiple ecosystem services in rain gardens from two different climatic regions in the US. We instrumented three rain gardens in each city (Charlotte, NC and Lafayette, IN) to sample influent stormwater runoff and infiltrating water via lysimeters during summer 2017. We measured plant and insect biodiversity and recorded landscape and residential use characteristics in the vicinity of each rain garden. Lastly, are conducting seasonal measurements of denitrification rates (i.e., the conversion of nitrate into dinitrogen gas) at two depths (0-5 cm; 10-20 cm) to quantify nitrogen removal. We are currently analyzing data from our summer and fall sampling and will continue seasonal sampling through 2018 and will associate these functions with characteristics of the structure itself and attributes of surrounding areas. This research is supported by with two undergraduates at Purdue University and one MS student at the University of North Carolina Charlotte.

Texas A & M University (F. Jaber, Z. Sheng; C. Munster ): Texas A& M Continued to update GIS coverages for the watershed, sub-basins, irrigation districts and aquifers within the USDA NIFA study area (from San Marcial in New Mexico to Presidio, Texas), crop acreage and flow data at gauge stations, irrigation diversions. Updated Paso del Norte Watershed Council Website. Shared data and GIS coverages with irrigation districts and regional water planning groups as well as researchers.

Texas A & M University (F. Jaber): Identification of sediment loading sources to urban lakes. Water quality samples and flow rates are being currently collected in Fort Worth from different parts of an urban water shed to determine the sources and landuses associated with sediment load to a residential lake in Fort Worth Texas. Automatic water samplers and bubbler flowmeters are used for this task. Stream flow sampling is currently occurring before streambank restoration (to occur in March next year) to establish baseline data.

University of Arkansas (B. Haggard): The accomplishments included (1) evaluating how water quality has been at Big Creek, a tributary to the Buffalo (National) River, which has been under scrutiny do to a hog farm which was permitted a few years ago (Sharpley et al., 2017), (2) updating the scientific community on where we are in terms of edge of field monitoring to help quantify effects of humn land use and BMPs on nutrient and sediment loads (Harmel et al., 2017), (3) help watershed managers use land use information to select areas for BMPs focus and implementation in the Ozark Highlands ecoregion (McCarty et al., 2017 - submitted), and (4) we evaluated floodplain soils as a potential phosphorus source and how water treatment residuals can be used to mitigate this source (Reavis and Haggard, 2016).

University of Illinois, UC (R. Bhattarai): UI-UC recently published a paper, where a ceramic pellet was manufactured using fly ash (mixed with clay and lime) for the removal of dissolved phosphorus. The results indicated that the developed pellets had the potential to treat contaminated water with high phosphorus concentration from the point and non-point sources. In the follow up study (the manuscript is in review), they evaluated the efficacy of using woodchips and fly ash pellet in flow-through tests for their abilities to remove nitrate and phosphate from the agricultural runoff. The results of this study suggest that woodchip denitrification followed by fly ash pellet filtration can be an effective treatment technology for nitrate and phosphate removal in subsurface drainage.

University of Rhode Island (A Gold, S Pradhanang, K Addy): From October 2016 to early January 2017 and April to September 2017, URI team deployed two sensors (the YSI EXO2 and the s::can spectro::lyser) in three RI streams (only two streams in 2017) to collect a variety of water quality parameters every 30 minutes. The three streams were selected as each watershed has a different dominant land use – forested, agricultural, and urban. Data is transmitted remotely into an Aquarius data management system. QA/QC on sensor data is completed through 2016. Grab samples were collected weekly during baseflow and collected a series of samples via an ISCO automatic water sampler during rain events in the fall of 2016. URI team is in the process of assessing relationships between sensor data and lab-analyzed field sample data to create site specific calibrations at the three streams for nitrate, dissolved organic carbon, phosphate, total phosphorus, total nitrogen, and TSS.   Data processing and paper development is in process.

University of Tennessee (E. Drumm): While manmade slopes are traditionally constructed with planar cross sections, natural stable slopes are usually curvilinear with significant concavity on the profile. This concavity occurs as a result of evolutionary processes where rain-driven erosion and sediment transport are balanced through slope shape adjustments; at the point of equilibrium, a relatively steady concavity with a uniform erosion rate is observed over time. Nevertheless, a true equilibrium state would be possible only if mechanical stability is satisfied. In this study, concave profiles in rainfall erosion equilibrium were found based on the principles of the well-known RUSLE2 model. Results show the existence of a family of steady shapes satisfying the condition of uniform erosion rate. Those steady concave shapes that also satisfy long-term mechanical stability were then investigated. The overall results suggest that concave slopes can be constructed to achieve both minimal steady-state erosion equilibrium and mechanical stability, leading to more "natural" and sustainable landforms with minimal sediment delivery during initial slope adjustments.

Virginia Polytechnic Institute (D. Sample); A proposal for monitoring a single watershed and a single BMP in the City of Virginia Beach was approved in August of 2017 and is underway. Another proposal was developed for monitoring small watersheds with homogenous land uses and to monitor stage at weirs near watershed outlets across the City of Virginia Beach; for purposes of water quality and quantity calibration of watershed models. A proposal submitted in 2016 that would provide partial funding for monitoring three BMPs and associated urban catchments at the Science Museum of Virginia (SMV) in Richmond, in collaboration with Virginia State University (VSU) was resubmitted in 2017, and was funded. This project will provide training opportunities for undergraduate students and faculty at VSU in surface water monitoring techniques.

Objective 2 : Develop and evaluate models for predicting BMP performance and water quality at the field and watershed­scales when considering climate change

North Dakota State University (Z. Lin) NDSU team modified a SWAT (Soil and Water Assessment Tool) model for the Red River of the North Basin to evaluate the effects of installing buffer strips along streams and drainage ditches on downstream water quality loads. The buffer strip law in Minnesota requires landowners to establish and maintain buffers along public waterways. The buffer strips range from 16.5 ft (5.0 m) to 50 ft (15.2 m). The deadline for farmers to create buffer strips is November 1, 2017. The modified SWAT model was run to compare the sediment and nutrient loads at the basin’s outlet near the border of the US and Canada. Based on the 2013 landuse data obtained from CropScape, the buffer strips would reduce sediment load by 2.3%, total nitrogen by 15.5% (nitrate by 13.5%), and total phosphorus by 16.8%.

Purdue University (S. McMillan) Effectiveness and societal acceptance of best management practices across the rural-urban gradient: The goals of this project are to (1) characterize current pollutant loads from two representative watersheds draining to Lake Michigan based on resident group (i.e., urban residential, suburban residential, rural residential, small agricultural, and medium/large agricultural), (2) determine the willingness of resident groups to adopt conservation and management practices, and (3) aggregate potential pollutant reductions based on willingness scenarios and share results with stakeholders. Preliminary model results show that although agricultural land is the primary developed land use in both watersheds, the annual load of sediments is greater from suburban/urban lands while dissolved pollutant loads are greater from agricultural lands. We are currently interviewing water resource managers and developing surveys to send to residents in spring 2018. This project is currently supporting two MS students at Purdue University.

Texas A & M University (F. Jaber, Z. Sheng, C. Munster) SWAT was used to model Green stormwater infrastructure (GSI) in a development in Houston to evaluate the impact of GSI on stormwater quality in three different residential and commercial urban density.
b- Data from field study was used to develop GSI subroutines to integrate in the next Release of SWAT. They developed SWAT model to simulate watershed hydrological processes and impacts of drought, initiate linkage between SWAT model with RiverWare model and MODFLOW, currently funded by two USDA NIFA grants.

University of Rhode Island (A Gold, S Pradhanang, K Addy) URI team conducted watershed modeling to predict stream flow, temperature and thermally stressful events within RI within the context of climate change and also developed hydrologic and water quality models to assess impacts of onsite waste water treatments systems in nitrogen loading in the bay area of RI. URI team contributed to database development and statistical modeling efforts to predict riparian zone function with respect to nitrogen and phosphorus cycling and greenhouse gas emission in agricultural areas of glaciated regions.   They also began to calibrate the AnnAGNPS model and the Riparian Ecosystem Management Model (REMM) with new default model parameters specific to dominant riparian geomorphic types in these glaciated regions. URI selected and instrumented four riparian sites to serve as calibration sites for modeling efforts.

Virginia Polytechnic Institute (D. Sample) Several urban hydrologic/ water quality models were developed for Virginia Beach and Fairfax, Virginia watersheds. BMPs are explicitly incorporated in these models to explore their effectiveness under changing conditions such as climate. We are also creating HSPF models of each of the City's watersheds that match watershed delineations of the existing SWMM models. We will be using these to explore the effect of aggregation and asses the comparability of the mesoscale models with the large scale Chesapeake Bay watershed model.

Objective 3: Develop methods to quantify modeling and monitoring uncertainty as affected by model representations of watershed processes and model input data

Mississippi State University (J. Paz) The results from MSU work on OFWS indicate that the nutrient load transported downstream can be reduced by controlling the volume of water reaching the OFWS during winter and by minimizing spring fertilizer applications. For example, pumping water out of the ditch to an on-farm reservoir could be implemented prior to expected rainfall events, to help reduce the nutrient load discharged with winter outflow events. Outflow events from the OFWS system was different among seasons with respect to the volume, frequency, peak, and time to peak discharge.

Purdue University (S. McMillan) Environmental trade-offs in water quality and climate regulation resulting from floodplain restoration using the two-stage ditch: Our overall objective for this project is to assess the environmental tradeoffs between water quality and climate regulation that may exist when best management practices (BMPs) are implemented in agricultural watersheds. We are focusing on two-stage channels that are implemented in agricultural drainage networks. These practices are constructed by creating inset floodplains within the existing channel thereby tripling the overall width. Specifically, we are aim to answer the following questions: (1) what is the contribution of denitrification to N retention at the reach scale? (2) what biophysical processes control phosphorus retention/export in streams with two-stage floodplains? (3) what are the patterns of greenhouse gas emissions in restored floodplains and how do they compare to natural floodplains and agricultural riparian zones? We are monitoring three two-stage channels in Indiana for sediment and water characteristics, including surface water chemistry, soil carbon and extractable phosphorus. We are also measuring rates of denitrification and nutrient flux in floodplain sediments seasonally. In summer 2017 conducted a larger survey of 10 two-stage channels and focused identifying variability in phosphorus dynamics in the floodplains and streambed at sites of varied ages and soil types. This project has also formed the basis for the Masters thesis for two students at Purdue and a component of two students’ dissertations at the University of Notre Dame.
