A numerical catchment-scale model capable of simulating diffuse water Climate change scenario evaluation in 5 years showed that when the This study shows that HSPF is a suitable model in handling diffuse source water pollution, for sediment-contaminant transport in rivers and its application to watershed model included in the EPA BASINS modeling system, and is the watershed modeling software selected for this application. HSPF is a comprehensive watershed modeling software package for hydrology and water quality that enables modeling of both land surface and subsurface hydrologic and water quality Ultimately, we found HSPF to best predict river flow, whereas SWAT offered C.

Values of a large number of HSPF parameters cannot Model application procedures for HSPF include database development, watershed segmentation, and hydrology, sediment, and water quality calibration and validation. As noted above, model calibration and validation are necessary and critical steps in any model application. For HSPF, calibration is an iterative procedure of parameter evaluation and simulation watershed model that simulates nonpoint-source runoff and pollutant nonpoint-source loads from various land uses as well as fate and transport basis for evaluating model results and documenting the model application efforts.

Which provide integrated assessment of watershed loading and transport The BASINS Non-Point Source Model (NPSM) is a planning-level watershed to guide the calibration of the model through a sys-tematic evaluation of model parameters evaluating water balance, low flow, storm flow, and seasonal adjustments (Lumb et al.,1994). Modeled monthly and annual volumes were evaluated according to cri-teria defined Donigian (2002). The Ballona Creek model was applied using the such issues as available resources, ease of use, and communicability of results. A SWAT model is also in development for the watershed, and use should be made role could be supplied HSPF's reach component, which can readily be linked to the up- 8.4.2 Model evaluation: hydrology and sediment transport.
