Stream channel erosion has long been suspected as the major contributor to long-term sediment yield from urbanizing watersheds. For San Diego Creek in southern California, measurements from 1983 to 1993 showed that stream channel erosion furnished 10(5) megagrams per year of sediment, or about two-thirds of the total sediment yield. Thus, because channel erosion can be a major source of sedimen...

Traditionally watersheds were spatial extents that capture rainwater. Recently it has been identified that unless the watersheds are not managed in an integrated sustainable manner, then not only the water resources but also other resources such as vegetation, fertile soil, fauna and flora get depleted. Rational management of upper and lower parts of a watershed is equally important for the sus...

Best management practices (BMPs) for agricultural diffuse pollution control are implemented at the field or small-watershed scale. However, the benefits of BMP implementation on receiving water quality at multiple spatial is an ongoing challenge. In this paper, we introduce an integrated approach that combines risk assessment (i.e., Phosphorus (P) index), model simulation techniques (Hydrologic...

BACKGROUND Freshwaters are the most threatened ecosystems on earth. Although recent assessments provide data on global priority regions for freshwater conservation, local scale priorities remain unknown. Refining the scale of global biodiversity assessments (both at terrestrial and freshwater realms) and translating these into conservation priorities on the ground remains a major challenge to b...

This paper investigated the vulnerability of agriculture sector and rural livelihoods in Bicol River Basin (BRB) Philippines to projected changes climate. The geographical characteristics BRB feature eight major sub-basins or watersheds consisting Libmanan-Pulantuna, Ragay Hills, Thiris, Naga-Yabo, Pawili River, Waras-Lalo, Naporog, Quinali. study applied combination participatory tools Climate...

Rivers and their natural potential are important useful to support the welfare of people's lives. The Tami River which is located in Keerom Regency included management priority because it a river border area Indonesia Papua New Guinea. ecosystem stores various kinds biodiversity that human life. research objective develop strategy for managing sustainable manner by considering as within nationa...

This study examined nutrient, water and carbon cycling processes and biodiversity patterns within replicated sub-watersheds that comprised different configurations of annual and perennial plant communities, ranging from conventional row crops to mixed annual and perennial systems to reconstructed native plant

In Ethiopia, national wide soil and water conservation is going on since 2010/11in all agro-climatic zones farming systems. Therefore, this study evaluated the effects of bund physico-chemical properties factors determining farmers' decision adoption SWC technologies in a watershed located sub-humid climate southwest Ethiopia. Two sub-watersheds, namely Nada Gulufa Gilgel Gibe I catchment, were...

in the present study, the soil and water assessment tool (swat 2000) model was tested on both a monthly and yearly basis and applied to the kordan watershed, located in iran. the main objective of the research was to assess the accuracy of the model in sediment-yield and surface water bicarbonate concentration estimation. the attributes of sub-watersheds, tributary channels and the main channel...
