Abstract: Purpose: The distributed watershed Chemical Transport, Transformation and Fate (CTT&F) Sub-model was developed and documented by the Environmental Laboratory of the U.S. Army Engineer Research and Development Center to characterize spatial and temporal dynamics of chemicals from both point and non-point sources. The sub-model simulates multi-chemical transport and transformation processes across watershed systems. CTT&F has a modular, process-oriented structure so that it can be easily modified, extended, or even provide a library of contaminant transport and transformation processes from which the user can select a sub-set of processes suitable for a particular application. This technical note describes the CTT&F submodel and its capabilities. As shown by its applications to military training ranges, CTT&F may be used in conjunction with distributed hydrologic and sediment transport models to quantify contaminant transport processes and certain chemical reactions in watershed systems. It can be used to study the environmental impacts of explosive compounds from military installations on surface water and groundwater quality. CTT&F can also be applied to other contamination problems for environmental assessment of the behavior of contaminants entering in watershed systems such as accidental spills of toxic chemicals, acid mine drainage and metals from mining areas, application of pesticides on the land surface, and the deposition of solid compounds from the atmosphere to land surface.
