Application of Integrated Environmental and Economic Simulation Models Using CEEOT-SWAPP to Evaluate BMPs at the Field and Watershed Levels

Organized by:
Ali Saleh
(Associate Director/Professor, Texas Institute for Applied Environmental Research, U.S. Tarleton State University; saleh@tarleton.edu)

Environmental models are used to assess and evaluate the impacts of various best management practices (BMPs) related to point and nonpoint sources at the field- (e.g., Agricultural Policy/Environmental eXtender, APEX) and watershed- (e.g., Soil and Water Assessment Tool, SWAT) levels.  However, models such as SWAT and APEX are only capable of simulating a limited number of BMP scenarios individually. Furthermore, most computer model applications do not include economic assessments of BMPs, which are critical for optimal practice implementation. A Comprehensive environmental and economic optimization tool –SWAPP (CEEOT-SWAPP) program was developed to: 1) simulate SWAT and APEX simultaneously, taking advantage of the strengths of both models for evaluating a greater number of BMPs for different land uses, including urban, agriculture, and forested lands, at the field- and watershed-levels; and 2) evaluate the economic impacts of selected BMPs using the Farm Economic Model (FEM) at the field- and watershed-levels.  In this workshop the CEEOT-SWAPP program and its nested models, including APEX, SWAT and FEM, will be introduced and distributed to the attendees. The application of CEEOT-SWAPP for the Upper North Bosque River watershed in Central Texas will be demonstrated. Participants are encouraged to bring a laptop (with MS Windows) for a hands-on demonstration, but can still view the demonstration if a laptop is not available.   The model will be loaded on each participant’s laptop.  Participants will also receive an instruction manual and a CD containing these materials.  Familiarity with the APEX, SWAT and FEM models is desirable but not required.

Water Supply, Pond Design And Levee Pond Economic Analyses Workshop

Organized by:     
Ernest W. Tollner
(Professor of Natural Resources Engineering, U.S. University of Georgia; btollner@engr.uga.edu)

The catchment analyses and storage pond enables harvesting water for multiple uses, one of which may be to supply a levee pond for Tilapia production. The catchment pond software performs a water balance over a year.  The watershed pond catches all or part of the runoff from a watershed upstream. The pond evaluates the area needed to provide adequate runoff to maintain pond volume during driest month and provides analyses of sustainability through the year in the event that the watershed area will not supply adequate water during parts of the year. A rating is provided for comparing pond feasibility over multiple sites. The levee pond software enables one to specify climates and soils where functional Tilapia levee ponds are possible. The pond requires knowledge of seepage rates of soils and knowledge of how to measure water flow rates from springs or streams. The user can select the appropriate climatic region, input an appropriate seepage rate for the soil and input the available stream or well flow. The user can try numerous pond areas and depths to determine if the specified pond will maintain its volume through the typical year. The workshop gives a detailed discussion on evaluating sites for pond suitability. A spreadsheet is presented for cost estimation of levee ponds. An engineering background is preferable but not required. Participants should have a feel for soil seepage and know what it is. They should be able to estimate watershed cover conditions; should be comfortable with estimating the flow of a well or small stream using bucket and stopwatch approaches. Users must bring their own laptop and will be provided a copy of the software in English and Spanish. The computers should be Pentiums running Windows 7 (Windows 8 not tested yet) with Microsoft Excel. A CD reader is required to load the software.

Vegetative Filter Strips with VFSMOD-W to Control Surface Runoff Pollution by Pesticides in Long-Term Environmental Assessments

Organized by:
Muñoz-Carpena Rafa
(Professor at University of Florida) and PAZMINO-HERNANDEZ, MARCO (Graduate Student at University of Florida)

Vegetative Filter Strip Modeling System (VFSMOD-W) is a design-oriented vegetative filter strip modeling system. The MS-Windows graphical user interface (GUI) integrates the numerical model VFSMOD, a utility to generate source (upslope disturbed area) inputs for the model based on readily available NRCS site characteristics (UH), and advanced uncertainty and sensitivity analysis, inverse calibration and design menu-driven components. Time required 4 hrs.

Nutrient Tracking Tool* – A user-friendly tool for calculating nutrient losses under various agricultural and forestry management practices

Organized by:     
Ali Saleh
(Associate Director/Professor, Texas Institute for Applied Environmental Research, U.S. Tarleton State University; saleh@tarleton.edu)

The Nutrient Tracking Tool (NTT) is an enhanced version of Nitrogen Trading Tool, a user-friendly web-based computer program originally developed by the United States Department of Agriculture (USDA). NTT estimates nutrient (nitrogen and phosphorus), sediment losses, and crop production from fields (or small watershed) managed under a variety of cropping patterns and management practices through its user-friendly web-based linkage to the Agricultural Policy Environmental eXtender (APEX). It also accesses USDA-NRCS’s Web Soil Survey (or user input) to for field, weather, and soil information. NTT provides producers, government officials, and other users with a fast and efficient method of estimating the nitrogen and phosphorus credits generated from implemented Best Management Practices (BMPs) at the field and (small watershed) levels for water quality trading, as well as other water quality and quantity programs. Recently, NTT has been modified to evaluate the economic impacts of selected BMPs using the Farm Economic Model (FEM) at the field- and farm (small watershed) levels. The information obtained from the tool can help producers to determine the most cost-effective conservation practice alternatives for their individual operations and provide them with more advantageous options in a water quality credit trading and similar programs. During this workshop NTT will be described and demonstrated.


NOTE: A certificate of completion will be awarded to each participants in all workshops by ASABE.
