Research Project: Spatial Data and Implementation Tools for Distributed Watershed Modeling Addressing NRCS Resource Concerns

Location: Agricultural Systems Research Unit

Project Number: 5402-13660-008-04
Project Type: Reimbursable

Start Date: Sep 01, 2011
End Date: Sep 30, 2014

Objective:
1. Mainstream USDA-ARS Agricultural Systems Research Unit (ASRU) modeling activities via the Object Modeling System (OMS) into NRCS Information Technology (IT) database access processes, corporate data stores, geospatial data access, and other data oriented activities; 2. Align ASRU modeling activities via OMS, particularly those related to the AgroEcoSystem-Watershed (AgES-W) model, with the NRCS Conservation Delivery Streamlining Initiative (CDSI) user interface architecture/infrastructure; 3. Implement AgES-W in the Cloud Services Innovation Platform (CSIP) and related OMS framework enhancements, as needed; and 4. Support the delivery of AgES-W model and tools in OMS to support CDSI regarding assessment of selected NRCS identified resource concerns.

Approach:
NRCS data oriented activities are progressing under the Conservation Delivery Streamline Initiative (CSDI), which will be leveraged to provide geospatial and temporal data access and delivery processes to run ASRU distributed watershed models, particularly the AgroEcoSystem-Watershed (AgES-W), and address NRCS Resource Concerns. The SCA will link data provisioning and model deployment to parallel activities in other ASRU-CSU agreements and NRCS activities. Potential synergies will be explored with the new NRCS Land Management Operational Database (LMOD) and Basin Analysis Geographical Information Systems (BAGIS). The Cloud Services Innovation Platform (CSIP) will be tested and used to deploy AgES-W on nested watershed models in the lower Cache la Poudre Watershed, where agricultural water and nutrient management are key drivers of water quantity and quality. Targeted spatial conservation practices will also be simulated in Iowa at field to watershed scales, where explicit spatial modelling and interactions between hydrological response units should be essential to capture the integrated responses that impact selected Resource Concerns. Using these two regional case studies, the data provisioning tools will be integrated with parameter estimation methods (being developed in parallel through other SCAs with CSU) to demonstrate general data management processes and their linkages with simulation in OMS. AgES-W model outputs will be mapped to selected NRCS Resource Concerns, where ARS and CSU will inform NRCS of progress through quarterly meetings and annual reports, and receive feedback and possible adjustments to NRCS priorities and CDSI tools and databases. Tools delivered in OMS and CSIP will be nationally scoped in terms of their abilities to be deployed over the continental USA using the same data provisioning processes and modeling tools. National application of the tools will be the future work of NRCS, but their input into the tool/framework development will be ensured, primarily through regular communication. The deliverables for each year (see Mutual Agreements below) will be demonstrated through public seminars and archived as simulation projects in Javaforge for future reference and development. Thus, the Colorado and Iowa case studies will serve as openly available templates for broader regional and national applications by stakeholders, including but not limited to NRCS.
