Underground waters play an important role in the present location of Shush country, as well as in the continued survival in the future. Due to the fact that the quality of groundwater resources of the study area has not been evaluated so far, this study evaluated the quality of groundwater resources of this area. In this study, the parameters of sodium, chloride, sulfate, total soluble solids, acidity, magnesium and calcium as parameters of the quality index of resources contained in the World Health Organization's Guidebook were evaluated. For this purpose, after normalizing the data and plotting of this data, Using Kriging and Inverse Distance Weighting methods spatial variation map of these parameters were provided and the results of two methods were compared. The results showed that in all parameters the accurasy of the Kriging in estimating the values was highest. After mapping the spatial changes of these parameters, the maps were combined and the groundwater quality map of study area was prepared based on water quality standards for drinking. The results showed that 23.67% of the groundwater in the study area was in the optimum level and 15.29% had a quality level for drinking.

Assessing existing water resources along with different routes of the river in a watershed is essential for its optimum use, conservation, and predicting flood and minimum flow. In addition, identification of runoff production processes is also important for assessing the effects of climate change and landuse on the hydrologic response of the watershed. There are several methods for separating base flow. In this study, the minimum local methods, sliding intervals, fixed intervals, one -parameter recursive digital filter and two -parameters recursive digital filter method were used for separating base flow at four hydrometric stations of Karaj River basin with a statistical period of 22 years (1991-2012). Then, the results were compared to determine the most appropriate method. The results showed that at Sierra-Kalvan and Nashtarod stations, the one-parameter recurrsive filter method with alpha of 0.925 and 0.950 could be a suitable method for estimating the base flow, due to the lack of significant differences between their results, as well as the minimum standard deviation. For Mored and Sierra stations, the one -parameter recursive digital filter with alpha values ​​of 0.950 and 0.975 was considered as a suitable method in separating base flow because of the lack of significant differences between their results as well as the standard deviation. The one -parameter recursive digital filter, therefore, has high spped in separating the flow hydrograph and can determine the continuous values of base flow.
