prioritization of sub-watersheds is very important in the natural sources and watershed management. in this study, the morphometric parameter and landuse changes using rs and gis techniques used in order to identify erosion-prone sub-watersheds. the morphometric parameter such as basin relief, the linear parameters (drainage density, bifurcation ratio, length of overland flow, stream frequency ...

Hydrological models are used to represent the rainfallrunoff and pollutant transport mechanisms within watersheds. Accurate representation of these dynamic and complex natural processes within a watershed is an important step in managing and protecting a watershed Artificial neural network (ANN) models are often used in hydrologic modeling. Typical ANN models are trained to use lumped data. How...

The shrinking Baiyangdian Lake and drying up rivers are widely observed in recent years. Due to the significant advantages in integrated analyses of natural and economic systems, emergy analysis is introduced in this paper to assess the health status of Baiyangdian Watershed. First, we establish a emergy based conceptual framework for the assessment, delineate an emergy flow diagram of Baiyangd...

Historical and recent remote sensing data can be used to address temporal and spatial relationships between upland land cover and downstream vegetation response at the watershed scale. This is demonstrated for sub-watersheds draining into Elkhorn Slough, California, where salt marsh habitat has diminished because of the formation of sediment fans that support woody riparian vegetation. Multiple...

The Muskingum-Cunge flood routing procedure has been incorporated into the Natural Resources Conservation Service Technical Release 20 (TR-20) hydrologic model. The TR-20 model is an event watershed hydrologic model used to analyze impacts of watershed changes (land use, reservoir construction, channel modification, etc) on volume of runoff and peak discharge. Rainfall runoff modeling is very i...

IIntegrated watershed management is known as a new pattern of planning which emphasizes importance of the sustainable development and management of on watershed: water and soil. Therefore, the goals of watershed management will be fulfilled when an integrated management is employed on watershed’s resources. In this study, Ghotorchay watershed is located in West Azarbaijan province, Iran was pri...

In continuation of the efforts made by the Illinois State Water Survey to develop a detailed hydrologic and water quality simulation model of the entire Illinois River Basin, a hydrologic simulation model was developed for the Vermilion River Watershed (one of the major tributaries of the Illinois River) to simulate streamflows using available climatic data. The model was developed using Hydrol...
