Abstract Lake Urmia has experienced climate change over the last decades, dramatically reducing water level. This study applies Soil and Water Assessment Tool (SWAT) to evaluate runoff management strategies under different scenarios in Zarrineh River Basin. We examined two strategies: projected based on business-as-usual (BAU) trend Changes Cropping Pattern (CCP). The variables were downscaled ...

A hydrologic and isotope mass-balance model is applied to two small, closed-basin lakes, Castor and Scanlon, in north-central Washington to describe the influence of hydroclimatic forcing on lake hydrologic and isotopic evolution. Simulations of lake responses to the combined effects of stochastic variability (i.e., random interannual fluctuations) and long-term (i.e., multidecade to century), ...

the present research focuses on the changes of urmia lake level. for this purpose, two timescales have been considered. the trend changes of temperature, precipitation rate and quantitative values of climate type for the observational period from 1968 to 2011 (past scale) and from 2011 to 2100 (future scale) have been analyzed. general circulation model (gcm) is considered for simulating the va...

This study develops the first daily runoff forecast system for Bukan reservoir in Urmia Lake basin (ULB), Iran, a region suffering from water shortages and competing demands. A weather downscaling model is developed large-scale raw forecasts of ECMWF NCEP to small-scale spatial resolutions. Various methods are compared, including deterministic Artificial Intelligence (AI) techniques Bayesian Be...

Relationships between distribution of periphytic diatoms and environmental variables in 19 rivers of the Lake Ladoga basin (Northwestern Russia) were examined using gradient analysis. On the basis of geology and river water chemistry, the Lake Ladoga basin could be separated into twomain parts, the northern and the southern sub-basin. The rivers in the northern sub-basin are slightly acidic and...

The Tso Kar lake basin in Ladakh, northwestern Himalayas (33 180N, 78 E, 4527 m a.s.l.) is located close to the modern boundary of effective moisture transport from the Indian summer monsoon. In order to reconstruct the possible monsoonal impact on the hydrology of the lake basin during the last 15 kyr, we studied the geomorphology of the basin and combined the results with multi-proxy records ...

this research was conducted to study the length-weight and length-length relationships and condition factor of six cyprinid fish species viz. alburnus atropatena , barbus lacerta , capoeta capoeta , carrasius gibelio , romanogobio macropterus and pseudorasbora parva from zarrineh river (urmia lake basin, iran). a total of 188 specimens ranging from 2.9 to 21.4cm in total length and 0.22 to 176g...

development projects in natural water resources like rivers and lakes, specially transferring water to use in agriculture, domestic and industrial sector without considering environmental values, causes irrecoverable and irreversible damage to ecosystem and future options. if we consider the future generation and species rights, those damages and costs can be very much than we take in. the abov...
