In this research, a 2D laterally averaged model of hydrodynamics and water quality, CE-QUAL-W2, was applied to simulate water quality parameters in the Ilam reservoir. The water quality of Ilam reservoir was obtained between mesotrophic and eutrophic based on the measured data including chlorophyll a, total phosphorus and subsurface oxygen saturation. The CE-QUAL-W2 model was calibrated and ver...

Background and Objectives: Dez dam located on Karun River is one of the largest Iranian dams. In a field study, EC, NO3, NH4, PO4, turbidity, TS, alkalinity, coli, temperature, chlorophyll a, DO, BOD5, and Secchi disk (at depths of 0, 2.5, 5, 10, 25, and 50 m)were measured at five sampling points during 2011-2012 water year. Materials and Methods: Water Quality Index and TSI were calculated for...

This study investigates flood avalanches in a dense reservoir network in the semiarid north-eastern Brazil. The population living in this area strongly depends on the availability of the water from this network. Water is stored during intense wet-season rainfall events and evaporates from the reservoir surface during the dry season. These seasonal changes are the driving forces behind the water...

Since the 1950s, the pollution of reservoirs has become serious. The water quality in reservoirs is deteriorating due to population growth, industrialization, and urbanization. In order to clarify the characteristics of water quality change in reservoirs, in-situ monitoring of water quality and phytoplankton were conducted in Jinpen Reservoir, Shibianyu Reservoir, Zhoucun Reservoir, and Zhelin ...

The impact of rainwater on the microbial quality of a tropical freshwater reservoir through atmospheric wet deposition of microorganisms was studied for the first time. Reservoir water samples were collected at four different sampling points and rainwater samples were collected in the immediate vicinity of the reservoir sites for a period of four months (January to April, 2012) during the North...

The Lorenz curve is used to estimate the heterogeneity of an oil reservoir. The corresponding permeability distributions in a series of concept reservoir models with a uniform average permeability but different heterogeneities are obtained and characterized by inverse calculation of the Lorenz curve. Then the development laws of a reservoir in relation to its heterogeneity are studied in method...

monthly and annual water and phosphorus mass budgets were set up over the year 2010 for thelake rio verde, brazil. limited data for the water budget was compensated using an interpolation methodwith data water budget data of a nearby reservoir. thus, errors of ca. 1.5% were estimated for the waterbudgets. dominant p mass input terms were inflows from the rivers and direct run off into the reser...

CO2-based Engineered Geothermal Systems (EGS) have been explored from the perspectives of thermodynamic performance, in-reservoir chemical reactivity, and economic viability. Previous works have correctly noted the important role that initial water content in the geothermal reservoir will play in determining the viability of the concept, but have not examined reservoir water content from a quan...
