INTRODUCTION: EDYS (Ecological DYnamics Simulation Model) is a general ecosystem simulation model that is mechanistically based and spatially explicit (Childress and McLendon 1999; Childress et al. 1999, 2002). The model simulates natural and anthropogenic-induced changes in plant, soil, animal, and watershed components across landscapes, at spatial scales ranging from 1 m or less to landscape levels (10 km and larger). It is a dynamic model that simulates changes on a daily basis over periods ranging from months to centuries. EDYS has also been linked with groundwater (MODFLOW) and surface runoff (GSSHA, CASC2D, HSPF) models to provide integrated watershed management simulation systems.
