Development of Field Pollutant Load Estimation Module and Linkage of QUAL2E with Watershed-Scale L-THIA ACN Model
The Long Term Hydrologic Impact Assessment (L-THIA) model was previously improved by incorporating direct runoff lag time and baseflow. However, the improved model, called the L-THIA asymptotic curve number (ACN) model cannot simulate pollutant loads from a watershed or instream water quality. In this study, a module for calculating pollutant loads from fields and through stream networks was de...
متن کاملOperationalizing Scale in Watershed-based Stormwater Management
Watershed-based stormwater management (WSM) has been proposed as more effective for stormwater management than traditional methods of controlling stormwater, which are carried out based on jurisdictional lines at the parcel-scale. Because WSM considers the watershed as a total unit, this method is considered to be more effective in reducing problems associated with stormwater management includi...
متن کاملComparison of Drainmod Based Watershed Scale Models
Watershed scale hydrology and water quality models (DRAINMOD-DUFLOW, DRAINMODW, DRAINMOD-GIS and WATGIS) that describe the nitrogen loadings at the outlet of poorly drained watersheds were examined with respect to their accuracy and uncertainty in model predictions. Latin Hypercube Sampling (LHS) was applied to determine the impact of uncertainty in estimating field exports and decay coefficien...
متن کاملWatershed-based Wetland Planning and Evaluation
Setting priorities for protection and restoration efforts is necessary whenever resources are not sufficient to target all sites simultaneously. When this occurs priorities should be set to maximize the ecological benefit gained from available resources. Prioritizing protection and restoration efforts in this fashion is hampered, however, by a lack of information that can be used by resource ma...
متن کاملDevelopment of a Prototype Web-Based Decision Support System for Watershed Management
Using distributed hydrological models to evaluate the effectiveness of reducing non-point source pollution by applying best management practices (BMPs) is an important support to decision making for watershed management. However, complex interfaces and time-consuming simulations of the models have largely hindered the applications of these models. We designed and developed a prototype web-based...
