Today, one of the major problems of flood control projects is watershed prioritizing for resource allocation and structural and non-structural practices. Due to the lack of hydrometric stations in many watersheds, is difficult determining the participation of sub catchments to create flood. So study the affective factors in watersheds through models such as multi-criteria decision analyzing sys...
Morphometric analysis in a watershed is requirement analyzing hydrological conditions watershed, because the properties of river networks and their relationship to each other will affect condition water resources watershed. This study aims analyze variations discharge two rivers upper Bengkulu morphometric aspects that influence it. For this reason, several are calculated, such as area circulat...
Due to the rapid population growth and urbanization in the City of Calgary, the Elbow River watershed in southern Alberta covering 1238 km has been subjected to considerable land-use changes over the last decade. The objective of this study is to assess the impact of land-use intensification simulated with a cellular automata (CA) model on the hydrological processes of the watershed using MIKE-...
Watershed is regarded as a very complex system of natural, social, economic and ecological dimensions and like any similar systems, exploitation of its resources requires a comprehensive and coordinated planning and management. Given the importance of watershed management projects for the development and management of natural resources, the enhancement of the efficiency of these activities is e...
Today, as the focus of watershed planning and management for sustainable development in many of the issues. Ecological watersheds can be evaluated and ranked them according to various ecological criteria for the watershed, one of the important steps in the planning and management of watersheds. Since the cost of watershed management projects and heavy construction project budget is limited, it ...
Soil Erosion Dynamic on Storm-Basis due to Land Use Correction in the High Priority Sub-Watersheds of Galazchai Watershed, West Azerbaijan, Iran
this study examines the relationship between land use/land cover (lulc) changes and surface runoff generation empirically to reveal how urbanization has altered the hydrologic characteristics of a watershed. a hydrological model, the soil and water assessment tool (swat), is employed to estimate the watershed runoff generation for two lulc scenarios from 2002 to 2010. the cypress creek watershe...
