[1] The Great Salt Lake is a closed basin lake in which level and volume fluctuate due to differences between inflows and outflows. The only outflow is evaporation, which depends directly on lake area and salinity, both of which depend on lake volume. The lake’s level, volume, and area adjust to balance, on average, precipitation and streamflow inflows by evaporation. In this paper, we examine ...
abstract identification & supervision of fluctuations in physical ecosystems have a special place in optimum using of natural resources. urmia lake is the largest interior natural lake of iran which its potentials and ecosystem & environmental characteristics attracted researchers and environmental planners attention. fluctuations in area and perimeter of the lake attracted many attentions in r...
Urmia Lake in northwestern Iran has been facing critical water level shrinkage in recent years with serious environmental consequences. It is expected that with the current trend, the lake will be completely dried out in a few years from now. This study attempts to assess the impacts of human activities on water level fluctuations of Urmia Lake by developing a comprehensive hydrologic simul...
The impact of hydrological regimes on the productivity in lake ecosystems has received considerable attention recent decades. This study tested hypothesis that water level fluctuations influence fisheries Lake Van. Monthly data from 2000 to 2014 were obtained Hydroweb and corresponding same time period acquired Turkish Statistical Institute. In order test whether demonstrated significant concor...
Lakes are very interesting sedimentary environments for the study of ancient climate, changes in sedimentary environments and lake level changes. Lake Zeribar is situated in the Zagros Mountains, Kurdistan, Iran. The main purpose of this research is to examine grain size sediments, geochronology and clay mineralogy accumulated in Zeribar Lake in order to check the water level fluctuations, clim...
The saucer-shaped depressions located at the river deltas of Poyang Lake are typical floodplain shallow sub-lakes subject to river-lake connection or isolation. The hydrological connectivity between these depressions and the main lake has a major influence on the hydrologic function and ecological integrity of the lake-floodplain and associated wetland habitats. This study explored the water le...
Ancient Lake Ohrid is a steep-sided, oligotrophic, karst lake that was tectonically formed most likely within the Pliocene and often referred to as a hotspot of endemic biodiversity. This study aims on tracing significant lake level fluctuations at Lake Ohrid using high-resolution acoustic data in combination with lithological, geochemical, and chronological information from two sediment cores ...
The Urmia Lake has distinctive nature, hydrodynamic and environmental properties that single out that from the other lakes in the world. Construction of Shahid Kalantari causeway can cause significant effects on natural regime of the lake. It may affect on environmental biology, hydraulic, water circulation regime and … . This paper deals with hydrodynamics of the lake. Two-dimensional s...
