Abstract

The Avan unconfined aquifer is one of the reliable groundwater storages in the west of Khuzestan province.The great Karkheh dam and the irrigation network development resulted in more water injection into the Avan aquifer. The purpose of this investigation is to evaluate uprising of groundwater table, to demarcate zones most affected by the water level and evaporation, and to estimate annual volume of water from the Karkheh dam storage into the Avan aquifer. In order to assess the spatial spreading of the groundwater level in different parts, pre- and post-dam water level maps were prepared . To understand the general trend of water level, unit hydrograph of the plain was also prepared. The collected results indicated that in average the water level risen about 5 meters and the most up coning was about 14 meters in the west and north. Two methods including flow channel and chemical balance was used  to compute the flow input from the Karkheh dam into the aquifer. The annual water inflow from the Karkheh dam storage into the aquifer using the average data was 7.3 MCM.
