The next step--incorporating diffuse pollution abatement into watershed management.
The majority of adverse changes in watersheds impairing water quality occurred over a period of thirty to more than one hundred years. In many areas over a period of about 80 years more than 90% of the wetlands were drained, cultivated and converted to agricultural and urban uses. This conversion changed the redox status of the soils and soil cover with a concurrent large increase of suspended ...
متن کاملDecision support for diffuse pollution management
The effort to manage diffuse pollution at the catchment scale is an ongoing challenge that needs to take into account trade-offs between environmental and economic objectives. Best Management Practices (BMPs) are gaining ground as a means to address the problem, but their application (and impact) is highly dependant on the characteristics of the crops and of the land in which they are to be app...
متن کاملDiffuse pollution in Oxford (Ohio, USA) watershed and performance of 'street sweeping' as a 'best management practice' (BMP).
Experimental results are described to evaluate the diffuse pollution profile according to land use in the catchments and street sweeping as a best management practice (BMP). We studied the variation of pollutant concentrations in outfalls discharging runoff from residential, commercial and high-traffic areas and in street sweeping. Pollution profiles varied with the land use in the catchments a...
متن کاملIdentifying and Classifying Pollution Hotspots to Guide Watershed Management in a Large Multiuse Watershed
In many locations around the globe, large reservoir sustainability is threatened by land use change and direct pollution loading from the upstream watershed. However, the size and complexity of upstream basins makes the planning and implementation of watershed-scale pollution management a challenge. In this study, we established an evaluation system based on 17 factors, representing the potenti...

59 To study the possible impact on the Lake Malawi/Nyasa/Niassa water quality due to actions performed at the watershed level, 61 and WL Delft Hydraulics to integrate physical and biochemical processes models in the lake and its basin which affect lake and 62 river water quality. The purpose of the integration of different models was to provide a set of tools in order to analyze the impact 63 o...
