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...

The complex tectonic and volcanic processes in the Ethiopian rift valley have resulted in the formation of volcano-tectonic structural depressions that became sites for many rift valley lakes. Lake Beseka is one of the rift valley lakes in the northern section of the MER near to the Afar triangle. The lake plays an important role in the ecology of birds and wildlife, as it is located in the nor...

During two field campaigns on Lake Issyk-Kul in March and August 2001, 179 high-resolution conductivitytemperature-depth profiles were measured, along with profiles of dissolved oxygen and light transmission. On the basis of this extensive data set, we investigated the large-scale vertical advective processes responsible for deepwater renewal in Lake Issyk-Kul. At some locations sampled in Marc...

Seepage meters were constructed to measure the influx of groundwater in Otsego Lake (Donnelly, 1999; after Lee, 1977). The meters were placed at the bottom of the lake to indicate the amount of water entering or leaving the lake through bottom sediments. Balloons attached to the meters were used to capture groundwater and samples were tested for chloride ion levels to ascertain whether it was g...

Previous studies conducted on the hydrography, chemical and biological characteristics of Lake Edku; one of the northern Nile Delta Lakes, concluded that this lake suffered from a high level of eutrophication, due to the heavy load of nutrients, especially phosphorus. Before deciding what type of treatment should be used for decreasing total phosphorous (TP), knowledge of the sources and sinks ...

Background: Consistent with Rule 100 of Michigan’s Water Quality Standards (WQS), Lake Allegan is protected for warmwater fishery, other indigenous aquatic life and wildlife, agriculture, navigation, industrial water supply, partial body contact recreation, and total body contact recreation. Prioritization of the Lake Allegan TMDL was driven by Michigan’s five-year rotating watershed assessment...

The Zerebar Lake is a shallow freshwater lake located in the northwestern Iran. The lake is surrounded by three human activities: agriculture, tourism and dam. The present study aimed to investigate (1) which human activity has the greatest impact on eutrophication of the Zerebar Lake (2) If phytoplankton communities, as the indicator, are correlated with the human activities. Water samples wer...

Urban lakes play an important role in urban development and environmental protection for the Wuhan urban agglomeration. Under the impacts of urbanization and climate change, understanding urban lake-water extent dynamics is significant. However, few studies on the lake-water extent changes for the Wuhan urban agglomeration exist. This research employed 1375 seasonally continuous Landsat TM/ETM+...
