Abstract

Withdrawal of ground water resource in Rafsanjan plain is about 450 million cubic meters in 1974. In this year, according to the hydrological calculation approximately, 98 million cubic meters of capacity permitted the table, has been added to harvest. Therefore, Rafsanjan region been forbidden region since 1974. According to statistics data, in 2003, extraction rate of ground water are recorded about 750 million cubic meters. But approximately 250 million cubic meters per year had added to the harvest in stored groundwater. For this rezone the level of groundwater falls down 80 cm per year. This has been introduced of agent to loss of farm land residential areas of failure. Down the level of groundwater decreased water quality including high and rising Ec, so that not to meet the standard value. In the Rafsanjan plain the geological layers are different, then, in this region, opening layers of earth is horizontally and vertically. This phenomenon alongs with techtonic movement may be resulted to a tragic event in this area.
