Minimum Requirements and Specifications Integrated Hydrological Watershed Modeling Software

The USDA, ARS, Sustainable Agricultural Water Systems Research unit in Davis, CA has a requirement for an Integrated Watershed Modeling Software to conduct integrated hydrologic investigations and perform complex studies of all aspects of, hydrology, hydrodynamics, eco-hydrology including multi-species and kinetic reactions at various scales on Windows 10 environment.

We need an integrated watershed modeling software that:

· Consists of a complete integrated physics-based fully distributed hydrologic modeling framework.

· Consists of advanced 3D interpolation, and geostatistics, including kriging of surface and subsurface medium.

· Capable of calculating water balance components at a sub-regional and grid scale within the project area

· Provides high level analysis of input climate data.

· Tightly integrated into GIS data and various geodatabases and shapefiles for model setup and interpretation of the results.

Operational Specifications:

The software must have a fully developed tutorial, documentation, and support service to easily apply the model and all its capabilities by a trained hydrologist.

The software must have a license capability (service) to be shared over a network.

The software must help develop all watershed flow components, including geometry construction, mapping, data handling, and visualization capabilities.

The software must include a variety of flow & transport numerical models, including particle tracking through coupled ECO Lab tool, nutrient transport, and robust control strategies for rivers and reservoirs.

The system must be able to perform duty with flexibility based on site-specific process requirements.

The software must be able to export/import results/raw data in a common format for analysis and evaluations.

The software provider must provide Service Maintenance as needed.

Software Specifications:
