Investigating the potential of geographic conditions and geomorphology in the storage of water resources using GIS(The studied area is Haj Aligholi Desert)

Water is life  resource  for living creatures especially  human  being .Water is the first and necessary toop for industrial development the base for agricultural production .if the mater of water and soil conservation be considered systematically and in the wide spread scale, in fact the consistency of natural environment is fulfilled (rajaei 1382).The resource area is located between 50 35 to 26 36 of north  latitude and 12 54 to 46 54 north longitude which reaches from north to alborz mountain frome east to moladeh village, from west to damghan city and from sout to hajaligholi playa . in this area the following villages are located , mehmandoost, dehmolla, kalatimolla, forat,zarrinabadmehdiabad,abbasabadT,vamerzan,bagh,jazan,heidarabad and haji abad which contain a population about 62000 person including damghancity. the main occupation of population of this region is gardening. The disaster of underground water table falling , Stalinization of water, increase of demand and region potential for increasing cultivating lands needs a full study for providing sustainable situation and is one of the most necessary need of the ragion. In order to reach to this aim all geographical, natural and especially geomorphology agents of region were strictly and in the field , using GIS hardware were studied to find the role of them on water resources of this area where is one of the centers of human activities in the field of agriculture . the results show that the geomorphology of the region including tall mountains, affecting on the amount of rainfall, also tectonized limestone formation, have an important role on water provision of the region, which with wide plainheads have the principle role oo feeding underground tables.
