Soil erosion has been one of the most important problems of watersheds in the world and is considered one of the main obstacles to achieving sustainable development in agriculture and natural resources. Identifying and prioritizing regions sensitive to soil erosion is essential for water and soil conservation and natural resource management in watersheds. The present research was performed in 2...

Geomorphometric features and land use/land cover are essential in the context of watershed prioritization for resources conservation and protection. Watersheds in tropical regions like the Philippines are under threat of degradation due to the combined effects of uncontrolled agricultural activities in the uplands and frequently increasing erosive precipitations brought about by climate change....

Watershed prioritization has become increasingly crucial for managing natural resources, especially the watersheds. A useful decision support tool to provide appropriate weights different morphological attributes with lineage soil erosion is required identify environmentally stressed areas watershed resources. This study examines Western Nayar delineation and further examination of watershed’s ...

Watershed prioritization is considered as the most significant aspect in watershed resource management and development program. The present work attempts to prioritize seventeen sub-watersheds Ruparel of Alwar district Rajasthan, India. For sub-watersheds, morphometric land use/land cover (LULC) analysis were performed using remote sensing GIS. Base map study area has been derived from SOI topo...

The investigation of basins for planning soil conservation requires a selective approach to identify smaller hydrological units, which would be suitable for more efficient and targeted conservation management programmes. One criterion, generally used to determine the vulnerability of catchments to erosion, is the sediment yield of a basin. In India, sediment yield data are generally not collect...

The research is focused on the integrated use of satellite remote sensing, Geographic Information System (GIS), and extensive field observation techniques for a better understanding impacts watershed characteristics hydrological processes floods. It aims to create methodology assessing flood hazards risk regional local scale so that protective measures can be designed. Floods have occurred in s...

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, 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...

   Identifying and determining the flood potential and prioritizing of the flood discharge in the sub-basins is very important in terms of watershed management, flood control and watershed management projects. In many watersheds, it is difficult to investigate and determine the impact of each of the factors and even upstream sub-basins on creating an outlet flood, especially in the sub-basins w...

Fractal scaling behavior of long-term records of daily runoff time series in 31 sub-watersheds covering a wide range of size were examined using the shifted box-counting method and Hurst rescaled range (R/S) analysis. These subwatersheds were associated with four agricultural watersheds of different climate and topography. The results showed that the records of daily runoff rate exhibited scale...
