Development of An Empirical Water Quality Model for Stormwater Based on Watershed Land Use in Puget Sound

Introduction The Sinclair and Dyes Inlet watershed is located on the west side of Puget Sound in Kitsap County, Washington, U.S.A. (Figure 1). The Puget Sound Naval Shipyard (PSNS), U.S Environmental Protection Agency (USEPA), the Washington State Department of Ecology (WA-DOE), Kitsap County, City of Bremerton, City of Bainbridge Island, City of Port Orchard, Suquamish Tribe and other stakehol...

Spatial Analysis of Agricultural Land Use Changes in the Khabour River Basin of Northeaster Syria

The Khabour River, southernmost tributary to the Euphrates, is a case study in the complexity of managing riparian resources. The river is located entirely within Syria but the watershed includes portions of Turkey and Iraq. Indeed, on account of the steep southward precipitation gradient in the region, the spring-fed Khabour is recharged almost exclusively by precipitation that falls on Turkis...

A Multiple-Objective Decision Analysis of Stakeholder Values to Identify Watershed Improvement Needs

T paper describes the use of multiple-objective decision analysis to qualitatively and quantitatively assess the quality of an endangered watershed and guide future efforts to improve the quality of the watershed. The Upham Brook Watershed is an urban watershed that lies at the interface of declining inner-city Richmond, Virginia, and growth-oriented Henrico County. A section of stream within t...

Impact of Watershed Management activities on flood hydrograph Using HEC-HMS Model (Case Study: Ramyan Watershed)

Increasing the use of water and soil resources in watershed in recent years and unproductive and inappropriate use of land ecology has exacerbated the occurrence of floods. In this context, watershed management is one of the most effective ways to cope with this crisis. This research quantify the results of these activities by calculating the decreased volume and discharge due to biomechanical ...
