Prioritization of watershed management scenarios under the influence of climate change using multi-criteria decision-making method (case example: Dalki watershed)
نویسندگان English
Due to its geographical location, Iran has also been affected by this phenomenon and its disturbing effects. Therefore, the phenomenon of climate change and the need to adapt to it must be accepted as a reality and included in the country's planning and water sector management. This study develops watershed management alternatives that can ensure optimal climate change adaptation benefits under different climate scenarios. Climate change adaptation scenarios were compared and prioritized through a hierarchical analysis process. Then, using the WASPAS method, Dalki catchment sub-basins were prioritized regarding the use of alternative methods and predicted scenarios. According to the opinion of 8 experts, there are eight scenarios of installing water harvesting measuring devices and smart meters (S1), using watershed methods to store water (S2), changing the cultivation pattern (S3), changing the cultivation time (S4), developing new irrigation methods (S5). , introduction of new types of products (S6), creating a balance between feeding and harvesting through non-structural and structural arrangements (S7) and reusing water and replacing wastewater for agricultural purposes (S8) were introduced to adapt the watershed to climate change. Based on the obtained results, sub-basin 8-2-2-4 is in the first rank and sub-basin 9-2-2-4 is in the last rank in terms of applying criteria in the implementation of alternatives to adapt to climate change.
