Abstract. Numerical models are an important tool for simulating temperature, hydrodynamics, and water quality in lakes reservoirs. Existing differ dimensionality by considering spatial variations of simulated parameters (e.g., flow velocity temperature) one (1D), two (2D) or three (3D) dimensions. The different approaches based on levels simplification the description hydrodynamic processes res...

This paper investigates the hydro-climatic reasons behind desiccation of Hamun Lakes in Iran-Afghanistan border. We analyzed changes flow Hirmand River (90 percent total inflow to lakes) at international border, and precipitation over this river’s sub-basin during 1960–2016 by calculating standardized indices for (SPI) discharge (SDI). applied Normalized Difference Spectral Indices using satell...

Theoretical review of ‘mining pit lakes’ indicates that like natural lakes such lakes display a huge diversity. They are typically in a non-equilibrium state with respect to their surroundings. Hence, at the decommissioning phase of mining operation a detailed technical study are required on different aspects of such created water bodies considering its morphometry, geology, hydrology, water qu...

Abstract. Observations of changes in terrestrial water storage (TWS) obtained from the satellite mission GRACE (Gravity Recovery and Climate Experiment) have frequently been used for cycle studies improvement hydrological models by means calibration data assimilation. However, due to a low spatial resolution gravity field models, spatially localized changes, such as those occurring lakes reserv...

Increasing pressures on natural resources has led to the adoption of water quality standards to protect ecological and human health. Lakes and reservoirs are particularly vulnerable to pressure on water quality owing to long residence times compared with rivers. This has raised the question of how to determine and to quantify the sources of priority chemicals (e.g. nutrients, persistent organic...

This study investigates nutrient sources and transport to receiving waters, in order to provide spatially detailed information to aid water-resources managers concerned with eutrophication and nutrient management strategies. SPAtially Referenced Regressions On Watershed attributes (SPARROW) nutrient models were developed for the Northeastern and Mid-Atlantic (NE US) regions of the United States...
