The Soil and Water Assessment Tool (SWAT) model is a continuation of nearly 30 years of
modeling efforts conducted by the USDA Agricultural Research Service (ARS). SWAT has …

Advances in the understanding of physical, chemical, and biological processes influencing
water quality, coupled with improvements in the collection and analysis of hydrologic data …

Abstract Model calibration is the procedure of finding model settings such that simulated
model outputs best match the observed data. Model calibration is necessary when the …

SWAT (Soil and Water Assessment Tool) is a comprehensive, semi-distributed river basin
model that requires a large number of input parameters, which complicates model …

Complex environmental models are controlled by a high number of parameters. Accurately
estimating the values of all these parameters is almost impossible. Sensitivity analysis (SA) …

Effective prediction of qualitative and quantitative indicators for runoff is quite essential in
water resources planning and management. However, although several data-driven and …

The objective of this study is to evaluate the relative potential of spatially distributed surface
and root zone soil moisture estimates in calibration of Soil and Water Assessment Tool …

Watershed models have been widely used for creating the scientific basis for management
decisions regarding nonpoint source pollution. In this study, we evaluated the current state …

Accurate knowledge of freshwater availability is indispensable for water resources
management at regional or national level. This information, however, has historically been …

Hydrologic and water quality (H/WQ) models are widely used to support site-specific
environmental assessment, design, planning, and decision making. Calibration and …
