Abstract

 Limitations of water resources and the ever-increasing demand for this vital resource have intrigued water crisis along with its unpleasant consequences. Hence, conducting more accurate studies on water resources is of special importance. In this study, water resources and specifically, ground waters in different parts of east of Guilan province, have been studied, and some practical strategies regarding the shortage of water which is obvious in different sectors, especially agriculture, have been presented. For this purpose, some field and laboratory studies were done and then the results analyzed. Findings showed that there are two distinct regions of ground water with highly exploited AQUIFERS. The first region is located in the south and southwestern parts of Roudsar and the second in the south and southwestern parts of Kelachay. In the map of iso TRANSMISSIVITY, these two regions include curves of more than 300 m2/day. This research also showed that the existence of salt water in some of the studied regions with shallow depth is not due to the entrance of the Caspian Sea's sub saline waters, but related to the fossilized salt water. That is why at times, one encounters salt water in shallow wells, which are occasionally artesian. Regarding a number of high discharge springs in the region, researches have been done that helped drawing the recession curves of Sefidab, Latak, and Leilakouh springs whose coefficients of recession curve ( a ), storage capacity (W) and discharge formulas are: For Sefidab spring(1999): a =3x 10-7, W=4.3 x 10-6m3 ,and Qt= 1.3 e-0.00000, while for Latak (2000) and Leilakouh(2003) springs: a =1x 10-7 , W= 2.3 x 106m3, and Qt =0.23 e -0.000000. AQUIFERS of the region include phreatic AQUIFERS, under pressure and artesian. The studied ground waters are of suitable quality for drinking and agricultural purposes. Moreover, there are not any nitrate problems in AQUIFERS and low BOD and COD values indicate the existence of healthy and clean waters.
