Salinity Simulation with WRAP
R. A. Wurbs
The salinity simulation features of the WRAP modeling system track loads and concentrations of water quality constituents through a system of river reaches and reservoirs subject to water supply diversions and return flows and reservoir system operations. Salt loads associated with various components of inflow, outflow, and storage are mixed and transported along with the water. Load losses and gains can also be specified as a percentage of stream flow loads and reservoir storage loads. Losses or gains through biological and chemical processes are not otherwise directly modeled. Thus, water quality constituents are assumed to be conservative. The WRAP water quality modeling capabilities are applicable to any essentially conservative constituent though motivated primarily by natural salt pollution.
