  Applying a proper management on water resources by identifying vulnerable areas as the first solution can be useful. The purpose of this study was to assess the vulnerability in the central plain of Guilan with drastic model. To identify the vulnerable areas of the central plain of the Guilan plain to pollution, drastic model was used and an aquifer vulnerability map was developed. The principles of the drastic model are based on the combination of seven components, depth to static level, net nutrition, aquifer environment, soil environment, topography, unsaturated environment, and hydraulic conductivity, which after ranking and applying weight impact on each component and algebraic composition of seven components, the final result will indicate the aquifer vulnerability. For this purpose, first, the information of the seven components in the central aquifer of Guilan was collected, and after entering in the GIS software, the layers needed for the model were finally prepared. Then, by using overlapping techniques after applying the required weight coefficients for each layer, a final vulnerability map was prepared. The profile of the drastic model varied from 82 to 182 for the vulnerability of the central aquifer of Guilan. The final drastic model map showed that 48.64% of the area had a high vulnerability and 50.55% had moderate vulnerability and only a small area of the plain (0.81%) had a low vulnerability. Based on the sensitivity method of map removal and single component and using the Monte Carlo technique, the depth distance to the station level was identified as the most effective component and saturation zone as the second most effective component in the central plain of Guilan.

  Industrial developments must follow environmental codes to sustain soil, water and air quality. Therefore, assessment of aquifer vulnerability potential for locating new industrial settlements is necessary. In this research, the vulnerability of Sari plain groundwater resources to the establishment of industrial zones is evaluated by DRASTIC model. Results show that Sari aquifer is very vulnerable to industrial development and the vulnerability map of the plain consists of three zones. The first, second and third zones that covers 10.49%, 56.66% and 32.85% of areal extent of the plain are classified as highly, very highly and too highly vulnerable, respectively. Parameter sensitivity analysis showed that the depth of the water-table is the most effective factor on the DRASTIC vulnerability index. Sari shallow aquifer is strongly affected by pollutants from agricultural and industrial activities. The study area is not suitable for the establishment of industrial estates based on the vulnerability map. Moreover, if environmental considerations are not respected by farmers and the existing industrial units in the plain, the aquifer will be suffering serious damages. Manuscript profile

  New industrial estates developments must follow the effective factors in protection, management and sustainable development of aquifers and water resources in a plain in order to meet the needs of people. Therefore, assessment of the aquifer vulnerability potential for locating new industrial estates settlements is necessary. So, investigation of the vulnerability of Sari plain groundwater resources for locating the industrial zones is necessery. In this research, the risk map of the plain was prepared using a drastic model to assessment of the effective hydrogeological factors in locating the industrial estates of Sari plain. The results of the Drastic model showed that Sari aquifer vulnerability is classified in three groups of highly vulnerable (10.49%,), very highly vulnerable (56.66%) and too highly vulnerable (32.85%). Sensitivity analysis based on two-way single parameter and parameter deletion methods showed that the depth of the water-table factor is the most sensitive factor on the DRASTIC vulnerability index. Sari aquifer is strongly affected by agricultural and industrial activities' pollutants due to shallow water-table; so, the study area is not suitable for establishment of industrial estates based on the final vulnerability map, the aquifer extreme vulnerability potential and the amount of exsisting pollutant. Also, if environmental considerations are not respected by farmers and the existing industrial units in the plain, the aquifer will be suffering serious damages. Manuscript profile
