Regional Hydro-Ecological Simulation System
RHESSys is a GIS-based, hydro-ecological model which has been developed to simulate water, carbon and nutrient flux cycling and transport in watersheds (Tague and Band 2004). RHESSys combines both a set of physically based process models and a methodology for partitioning and parameterizing the landscape.
RHESSys (Band et al., 2000; Band et al., 1993; Tague & Band, 2004) is a physical process-based model, which integrates hydrologic processes, biogeochemical cycling and 4 microclimate variability using the algorithms modified from the several existing models: TOPMODEL (Beven & Kirkby, 1979), BIOME-BGC (Running & Hunt Jr., 1993), and MTCLIM (Running et al., 1987). The Geographic Information System (GIS)-based model framework of RHESSys allows it to directly import remote sensing data to describe the spatial information such as land cover, soil type, leaf area index (LAI), and topography as digital elevation model (DEM).
