Abstract: The dam site selector (DSS) expert system (ES) is an aid for rating an area for use as a dam site and reservoir. The program is not intended for rating sites where the dam height is greater than 50 ft (15.2 m), more than ...

Abstract: A Web-based geographic information system (GIS) that can delineate watersheds in real time was developed for use in hydrologic analysis and to support hydrologic model operation on the Internet. The system integrates a ...

Abstract: Time series models provide a valuable tool for simulation and forecasting hydrologic variables. However, time series models require fitting long series of records. This study explores the applicability of soil water ...

Abstract: The overall goal of this project was to quantify the long-term water quality impacts of land management changes associated with increased demands for corn as a transportation biofuel feedstock in the United States. A ...

Abstract: Control of agricultural nonpoint sources of pollution is achievable through implementation of conservation practices at the farm or field level. There are several approaches to achieve a targeted implementation of conservation ...

Abstract: Changes in land use can have significant impacts on hydrology and the environment. The Long-Term Hydrologic Impact Analysis model and a geographic information system-based Soil Conservation Service curve number method were ...

Abstract: Concrete linings of field canals are seriously damaged by frost heave in the north of China. However, the mechanism causing lining damage is too complex to be described quantitatively, and present models are insufficient ...

Abstract: The aim of this study was to improve streamflow predictability using the soil and water assessment tool (SWAT) model for baseflow estimation in a steeply sloped watershed. The two objectives were (1) to appraise ...
