Predicting Sediment Detachment and Channel Scour in the Process-Based Planning Model ANSWERS-2000
ANSWERS-2000, a continuous simulation, distributed parameter nonpoint source model for simulating runoff, sediment, and nutrients from disturbed watersheds was updated to include a critical-shear rill detachment subroutine, an improved interrill detachment subroutine, and a channel scour …

Procedure to Quantify Environmental Risk of Nutrient Loadings to Surface Waters
… The procedure utilizes the NPS pollution model ANSWERS-2000 to generate upland pollutant loadings to receiving waters. The pollutant loading impact on stream water quality is estimated using the stream module of Hydrologic Simulation Program FORTRAN (HSPF). The risk is calculated as the product …

Simulation of Runoff and Pollutant Loss in Urbanizing Watersheds
… roads and buildings on hydrologic processes. The ANSWERS-2000 watershed model was modified to simulate watersheds with mixtures of agricultural and urban areas. In addition, components were added to simulate atmospheric deposition and urban management practices, including wet ponds, dry ponds, and …

Estimating Bacterial Loadings to Surface Waters from Agricultural Watersheds
… The bacterial model was incorporated into the ANSWERS-2000 model, a continuous, distributed, nonpoint source pollution model. The model was tested using data from two plot studies. Calibration was required to improve runoff and sediment predictions. Bacterial model predictions underpredicted …
