An Internet-based Spatial Decision Support System for Rangeland Watershed Management.

Miller, R.; Guertin, D.P.; Heilman, P. - 2003

The impact of livestock grazing on water quality, especially erosion and sedimentation, is an important concern in the southwestern United States. In response to Federal and State regulations, Best Management Practices (BMPs) for rangeland management are being developed and implemented in many...

A Dual Monte Carlo Approach to Estimate Model Uncertainty and its Application to the Rangeland Hydrology and Erosion Model.

Wei, Haiyan; Nearing, Mark A.; Stone, Jeffry J.; … - 2008

Natural resources models serve as important tools to support decision making by predicting environmental indicators. All model predictions have uncertainty associated with them. Model predictive uncertainty, often expressed as the confidence interval around a model prediction value, may serve as...

Mathematical Simulation Tools for Developing Dissolved Oxygen TMDLs.

Vellidis, G.; Barnes, P.; Bosch, D.D.; Cathey, A.M. - 2006

In many regions of the U.S., low dissolved oxygen (DO) is a common freshwater impairment. States, territories, and tribes of the U.S. are required by federal law to develop Total Maximum Daily Loads (TMDLs) for waters not meeting established DO standards. Regulators and other professionals are...

Uncertainty in TMDL Models.

Shirmohammadi, A.; Chaubey, I.; Harmel, R.D.; Bosch, D.D.; … - 2006

Although the U.S. Congress established the Total Maximum Daily Load (TMDL) program in the original Clean Water Act of 1972, Section 303(d), it did not receive attention until the 1990s. Currently, two methods are available for tracking pollution in the environment and assessing the effectiveness...

Spatial Decision Support System for Watershed Management

Rao, K.; Kumar, D. - In: Water Resources Management 18 (2004) 5, pp. 407-423

A prototype spatial decision support system (SDSS) is presented for watershed management. The SDSS integrates landuse/landcover derived from the remote sensing data, real-time hydrological data, geographic information system, and a model-based subsystem for computing soil loss, land capability...

Multicriteria Decision Support System for Regionalization of Integrated Water Resources Management

Coelho, Ana; Labadie, John; Fontane, Darrell - In: Water Resources Management 26 (2012) 5, pp. 1325-1346

Successful implementation of integrated water resources planning and management (IWRM) requires delineation of regions that are relatively homogeneous with respect to multiple criteria, including hydrographic, physical-environmental, socioeconomic, and political-administrative aspects. The water...
