Several best management practices (BMPs) have been implemented through Water Quality Management Plans (WQMPs) in the West Fork Watershed of Trinity River Basin in Texas, USA, where nonpoint source pollution is a serious concern. Major sources of pollution are sediment erosion and nutrients. The objective of this study was to evaluate the long-term impact of implementation of WQMPs on nonpoint s...

Modern land-use planning and conservation strategies at landscape to country scales worldwide require complete and accurate digital representations of river networks, encompassing all channels including the smallest headwaters. The digital river networks, integrated with widely available digital elevation models, also need to have analytical capabilities to support resource management and conse...

Like many research universities, the University of Minnesota (UMN), and its Libraries, attempts to understand the nature and intensity of data produced by its researchers, and address the management and stewardship of its institutional research output. The recent activities of the Libraries, in support of and in conjunction with campus-wide efforts, illustrate a set of approaches that show the ...

â increase in wastage of soil resources in watershed is a persistent challenge that with increase in population and pressure on natural sources and unstable plantation on gradient farms and soils cause production reduces on farms, and also decrease in daily ratio of farms to population can cause more pressure on lands and natural resources.lavarefin watershed placed in 60 km from bandarabass in...

Maintenance of a sustainable clean water supply is critical for our future. However, watershed degradation is a common phenomenon around the world that leads to poor water quality. In order to protect water resources, the Watershed Forest Management Information System (WFMIS), was developed as an extension of ArcGIS and is described in this paper. There are three submodels to address nonpoint s...

Background: An integrated watershed management approach adopted in the recent decade caters to of natural resources and overall economic improvement region. Watershed projects need be evaluated after implementation know effectiveness programmes on rural enhancement beneficiaries. Methods: The present study describes identification impact indicators that play important role measurement performan...

This research has concentrated on the physical and socio-economic impacts of vegetation-based management scenarios targeting on flooding and soil erosion issues in the Ramian watersheds. The Ramian watershed with an approximate area of 24000 ha is located in Golestan, Iran. For each sub-watershed, four biological actions (activities) and 16 management scenarios have been considered. Physical im...
