Investigating of Spacing Spatial and Temporal Distribution of Quality and Quantities Groundwater at Noorabad Plain

Results of urban growthing and increasing pollutants water leads to decreasing of quality and quantity of water resources. Quality and Quantities groundwater at Noorabad Plain are conducted in this study. For this purpose, traced the hitographs of rainfall from April 1997 to 2017. According to the drawn hitograph, the years 2004, 2010 and years 2014, 2017 were selected as rainy years and low rainfall years respectively. Spatial distribution’s map for concentration of groundwater quality parameters and groundwater level by Kriging method were created. In addition, the best of selection of model according to the assessment criteria (RMSES, RMSE, ASE and MSE) were created for these years. By dividing the product by the rank of each parameter in its average weight on the total number of parameters, the GQI index was prepared to study the groundwater quality in the years studied. The results show that: the water quality of this area is in a good grade during the studied years. In all of the examined years, the northern and southeast areas of the noorabad plain have better quality than other areas. By investigating of quantitative and qualitative maps, it was noted that, by increasing the distance of groundwater level from the ground, water quality becomes more appropriate.
