abstractthe understanding of water resources for the purpose of ground and surface water management as two inseparable systems is great importance. in this study by examining the time series of climatic variables (precipitation), hydrological (flow and consume) and the level of water table, the parameters associated with each other and with fluctuating water table can be realized. there was a d...

in this study, a bearing capacity device is designed and fabricated to determine the load-settlement behavior of three circular footing models resting above the ground water table. capillary rise in the studied well graded sand is measured and the level of the water table is controlled at the desired heights during each bearing capacity test. moreover, shear strength parameters and soil water r...

abstract this research investigates the effect of drought on ground water table of neishabour plain. the precipitation data of nishabour synoptic station during 1990-2001, the bar climatology station during 1964-2001 and the data of hydrometric stations of kherv and bar in 1996-2001 have been used as the base of analysis. the method of herbest et all has been used to analyze the drought. using ...

recent droughts and indiscriminate use of ground water for agriculture, is the main problems of the especially desert country.water crisis has gripped all of country plains, and due tothe reduction of surface water resources and successive droughts, illegal exploitation of ground water resources is increasing.the knowledge of the water balance plains can be helped in the water resources managem...

Groundwater drought denotes the condition and hazard during a prolonged meteorological drought when groundwater resources decline and become unavailable or inaccessible for human use. The aim of this study is to identify the influencial factors on groundwater drought in Hamadan- Bahar Watershed,Iran, to understand the forcing mechanisms. The Standardised Precipitation Index (SPI) has been used ...

Koot - Hamoodi are two units from seventh units out of 1&2 irrigation and drainage network in Dasht-Azadeghan project where was past about 7 years from their operation. Results of the studies were showed before construction of network; ground water table in considered of this area was high and more than 90% of these lands were high and too high in saline and alkaline. After construction and ope...
