Upper Gotvand dam is constructed on the Karun River located in the south west of Iran. In this paper, 2D and 3D models of the dam together with the foundation and abutments were constructed and several seepage analyses were carried out. Then the gypsum veins scattered throughout the foundation ground and also the seepage pattern were included in the models, hence the dissolution law of gypsum, ...

BACKGROUND The organochlorine pesticides (OCPs) are among the most commonly used in water streams around the world. Most of these contaminants are highly hydrophobic and persist in sediments of rivers and lakes. Studies have suggested that OCPs may affect the normal function of the human and wildlife endocrine systems. OBJECTIVES The aim of this study is to determine the concentrations of sel...

Water resources are vital to the survival of living organisms and contribute substantially development various sectors. Climatic diversity, topographic conditions, uneven distribution surface water flows have made reservoirs one primary supply in Iran. This study used Landsat 5, 7, 8 data Google Earth Engine (GEE) for supervised monitoring dynamics reservoir eight Iranian dams (Karkheh, Karun-1...

Different types of Optimizing the Parameters Hydrological Routing Methods using Particle Swarm Optimization (PSO) Algorithm for Flood in Karun River

As a departure from traditional situational perspectives, researchers have given increased attention to the dispositional basis of attitudes. Recently, Hepler and Albarracín (2013) introduced a construct that they called "dispositional attitude" and provided validity evidence for a new scale--the Dispositional Attitude Measure (DAM). Although the DAM was introduced as a "new" approach for asses...
