Abstract:
Water is one of the most essential needs of mankind. Water is the source of life and the reason for the formation of many settlements on the Earth's surface. The shortage of safe drinking water, especially in third-world countries including our country, is presented as one of the fundamental problems. Lack of control over quality and the excessive amount of extraction and consumption can exacerbate these problems and bring serious threats. Therefore, it is necessary to pay attention to various aspects of this vital resource while implementing principled policies. One of the newest approaches in this field is risk management, which the World Health Organization also emphasizes the importance of using (Swedish, 2009, 13). The present research, by identifying and leveling the risks that threaten drinking water resources in rural centers of the Sorkhun aquifer, has proceeded to prioritize and level these centers based on the amount of risk existing in their drinking water resources. The research method in this study is descriptive-analytical using a survey method and by preparing a questionnaire from the perspective of two groups: village administrators (Dehyars) and officials. The statistical population studied includes the Sorkhun aquifer, the village administrators of Sorkhun rural district, and 20 officials who were selected as the statistical sample. Finally, these villages were ranked using the AHP (Analytic Hierarchy Process) and TOPSIS models and divided into five levels, including: very high risk villages, high risk villages, medium risk villages, low risk villages, and very low risk villages.

Risk Leveling of Drinking Water Resources in the Villages of Dasht-e Sorkhun, Bandar Abbas (Case Study: Sorkhun District - Qaleh Qazi Section, Bandar Abbas County) 1 Ahmad Nohegar Associate Professor, Faculty of Agriculture and Natural Resources, University of Hormozgan Fatemeh Riahi Chalvani Master's Student in Watershed Management Engineering, University of Hormozgan Nahid Akbari Samani MSc in Geography and Rural Planning Date Received: 2011/09/27 Date Accepted: 2012/01/01 Abstract Water is one of the most essential human needs.
Given what has been said, the main objective in the present research is to investigate and study the status of reservoirs and the drinking water distribution network, and to identify and classify the risks that threaten these resources during the maintenance and supply stage of drinking water, and finally, to prioritize and level rural centers based on these risks.
