Abstract:
CADIL (Chemical Adsorption and Degradation In Land) is a moisture and chemical species mass balance model which simulates chemical transport through soils. It includes the processes of deposition, infiltration, adsorption (Freundlich isotherm) and first-order (bio-)chemical degradation of chemicals. It also simulates the effect of soil temperature on chemical degradation. Chemical transport in soil water may be either vertical or lateral. Both macropore and matrix flows of chemicals in soil water are modeled. CADIL couples to AGTEHM, which in turn calculates soil water transport through the bulk matrix and soil macro-pores. AGTEHM simulates interception, throughfall, infiltration, soil evaporation, plant transpiration, and surface runoff.
