Regional Hydro-Ecological Simulation System (RHESSys) ModelEntry ID: NASA_ARC_RHESSys
Abstract: The Regional Hydro-Ecological Simulation System (RHESSys) is a GIS-based, hydro-ecological modeling framework designed to simulate carbon, water and nutrient fluxes. RHESSys combines both a set of physically based process models and a methodology for partitioning and parameterizing the landscape. RHESSys' architecture models the spatial distribution and spatial-temporal interactions between the ... different processes at the watershed scale. RHESSys, as described here, presents a significant modification of earlier versions of RHESSys as described in Band et al., (1991, 1993) and referenced by Mackay and Band (1997), Creed and Band (1998) etc.
RHESSys process models have been adapted from several pre-existing models. Specific algorithms within these original models have been modified to reflect various developments in the associated literature or to fit within the RHESSys modeling framework.
