Abstract:
A water budget model was developed to estimate year-end lake volumes of Goose Lake, Oregon-California, to determine whether an accurate reconstruction of lake volumes/levels could be made with several synthesized or partial volumetric components. Components evaluated were the lake level/volume observations, precipitation, streamflow, and evaporation during the data-rich study period, 1946 to 1975. By regressing estimated year-end volumes against actual volumes (using actual volumes as the input at the beginning of each year) a correlation coefficient of 0.97 was obtained. By letting the series

Abstract. Declination of lake water levels are extensively influenced by anthropogenic activities along with basin size, topography, and lake size. Lake Urmia was one of the largest hypersaline lakes in north-west Iran. Main outflow from the lake are evaporation and possible groundwater flux, whereas major sources of inflow are surrounding rivers and several streams. Overall, annual evaporation is higher than precipitation. The lake Water Level Fluctuation (WLF) is a function of inflow, rainfall, evaporation and groundwater flux. The aim of this study is to assess the accuracy of different Rem

Lake Urmia, located in the north-west of Iran, is one of the largest hypersaline lakes in the world.

An integrated water balance model of the Lake Urmia Drainage Basin (LUDB) and Lake Urmia was developed to identify these main drivers of the significant changes, and to investigate the possible future evolution of the lake under effects of projected climate change and land use change.

Abstract:
Shallow lakes have a tendency to be present in one of two broad alternative states: clear or turbid. Increased demand for water by humans, drought and climatic shifts may reduce water availability and increase the frequency or magnitude of lake water level drawdown. However, there is conflicting evidence as to how shallow lakes respond to water level decline. Many lakes become clearer due to reduced nutrient inputs from inflowing rivers. Alternatively, internal processes, such as the resuspension of sediments, can exacerbate the turbid state as lower water levels attenuate less wind-induced tu
