Abstract
Every country’s influence and livelihood is centered on that country’s water source. Therefore, many studies are being conducted worldwide to improve and sustain water resources. In this research paper, we have selected and researched the water scheme for groundwater recharge and drinking water supply of drought prone areas. The water project is aimed at connecting the drought prone areas of the three districts of Tamil Nadu to filling up the ponds in their respective villages and raising the ground water level and meeting the drinking water requirement. We have chosen a multi-criteria decision method to select the best alternative in a complex situation. When reviewing the implementation of this water project, many experts and people who will benefit from this project may have some hesitation and ambiguity in their suggestion on choosing the best water distribution system.We believe that the benefits of this project can be fully availed of if we choose a water distribution system. Our contribution in this article is to choose the best water distribution system for this project by use of our proposed multi-criteria decision making (MCDM) methods, hesitant fuzzy standard deviation with multi-objective optimization method by ratio analysis (HFSDV-MOORA), hesitant fuzzy standard deviation with technique, for order preference by similarity to an ideal solution (HFSDV-TOPSIS) and hesitant fuzzy standard deviation with VIsekriterijumsko Kompromisno Rangiranje (HFSDV-VIKOR), which will provide the best solution for improving the water resource for the drought-prone areas of three districts. Finally, we have identified and compared the correlation coefficient between proposed methods. As a result of the study, it has been found that the best water supply system is closed concrete pipes laid along agricultural land through the rural areas.
Highlights
In agricultural production, soil, seed and water are basic requirements
We have used a hesitant fuzzy set with the SDV weight finding technique in the weighting area, which is considered an important part of the multi-criteria decision making (MCDM) method used here
We proposed HFSDV- MOORA, HFSDV-TOPSIS and HFSDV-VIsekriterijumsko KOmpromisno Rangiranje (VIKOR) for solving
Summary
Soil, seed and water are basic requirements. sunshine, insecticides, fertilizers, suitable climates and human labors are needed. The main impact of irrigation is in terms of the increased agricultural yield. These results affect different human environments, like social, cultural, economic and political, besides the agricultural development.many studies are being conducted worldwide to improve and sustain water resources. Tamil Nadu is a water stressed state and depends heavily on ground water for irrigation. In Tamil Nadu, ground water is considered as a main resource for irrigation. The canal irrigation system is an important primary need of agriculture. The groundwater level is decreased, because of the rise in the population, development of industries, illegal well pumping, etc. The water distribution system will help recharge ground water table and benefit farmers in Coimbatore, Erode and Tirupur districts
