Modeling of Watershed Systems

The overall objective of the MoWS research group is to gain better understanding of the precipitation-runoff processes and use this knowledge to develop improved hydrologic models. The main research topics include: • Add functionality and improvements to the MoWS simulation models being developed and integrate with other hydrologic, hydraulic, and climate models. • Enhance the models to use the best and latest topographic, climate, geologic, and land-use data sets as direct input to process algorithms to increase the physical nature and temporal and spatial resolution of model input. • Develop national model structure and calibration strategy for national model application.

version 2.0 (THIS RECORD IS IN DEVELOPMENT)

The output data in this collection is essentialy identical to that in version 1.0, but is more formally packaged. It includes reference to source data sets and software used to derived the output. Input data include two routing parameters from the NHM archive ("paramdb") of PRMS parameters: hru_segment_nhm and tosegment_nhm. hru_segment_nhm defines the stream segment to which the fluxes from each HRU arrives. tosegment_nhm defines the next downstream segment in the Geospatial Fabric. The values for both of these parameters reflect the national stream segment identifiers (as opposed to region-specific equivalents, hru_segment and tosegment). The software is provided in order to allow regeneration of the headwater...

A hydrologic model was developed as part of the Southeast Regional Assessment Project using the Precipitation Runoff Modeling System (PRMS), a deterministic, distributed-parameter, process-based system that simulates the effects of precipitation, temperature, and land use on basin hydrology. Streamflow and other components of the hydrologic cycle simulated by PRMS were used to inform other types of simulations such as water-temperature, hydrodynamic, and ecosystem-dynamics simulations.
