In order to understand the pattern and trends of environmental evolution Lake Urmia (Iran), one largest terminal lakes in Western Asia before its level drop over past two decades, sediment cores (Golman 6, 8.0 m; Golman 7, 12.5 m) were collected from recently dried-out southwestern part lake. These represent a continuous sedimentary sequence, composite core, that was extensively studied for gra...

Abstract This study investigates the future changes in precipitation extreme indices Lake Urmia Basin during period 2021–2100 compared to base (1987–2016), based on Coupled Model Intercomparison Project Phase 5 models. Trend analysis was performed using Mann–Kendall test and Sen's estimator. The output of these models downscaled by Long Ashton Research Station Weather Generator method for repre...

Abstract Growing agricultural and domestic demand exacerbates water shortages globally, creating substantial environmental challenges, especially in lakes wetlands ecosystems. This paper presents a stationary policy to restore sustain the level natural using new version of hedging rule that accounts for time-dependent allocation municipal sectors under different climate change projections. The ...

The upper portion of the Midale Beds of southeast Saskatchewan were deposited in a Tidal Flat environment and show a great deal of variation in reservoir quality. They were vulnerable to erosion as a result of an extended period of exposure. Our model of deposition suggests that the carbonates prograded laterally as clinoforms and built up to sea level (Kent and Lake, 2012). The potential for p...

Limited water resources with uneven distribution in addition to the growing demands are the main challenges of the water governance in Iran. The Government has planned several water resources development project and due to their complex technical, socio-economical, and environmental outcomes, comprehensive evaluation is needed. To select more adaptive and accountable projects, suitable group de...
