Rice production presents a unique problem with respect to agrochemical runoff because of the high seasonal rainfall, water management, and proximity of cropland to surface water bodies. Existing pesticide transport models are not configured to simulate the flooding conditions, overflow, and controlled releases of water that are typical under rice production. RICEWQ was developed to… Read More>
RIVWQ simulates water and chemical mass balance. Water mass balance accounts for conservation of mass from time-varying discharges. Chemical mass balance can accommodate dilution, advection, volatilization, partitioning between water/sediment, decay in water and sediment, burial in sediment, and re-suspension from sediment. The model can simulate up to five chemical/metabolites.
The Vegetated Filter Ditch Model (VFDM) was developed by Waterborne to design and evaluate the effectiveness of vegetated filter ditches as a Best Management Practice (BMP) to reduce the occurrence of agrochemical residues in downstream waterways. This model can also be used as a design tool to assist in the construction of a vegetated ditch… Read More>
