locate suitable sites for construction of an underground dam by using ahp multi-criteria decision

Identification of suitable sites for subsurface flow harvesting using underground dam (Case study: Border basins of Torbat-e-Jam County)

Every year, large amounts of the country's water resources leave the country through political borders. Subsurface water is part of these resources that flows on the dry bed of rivers and becomes inaccessible without proper exploitation. Since Iran has many common borders with neighboring countries, it is necessary to pay attention to this issue. One of the appropriate solutions to prevent the ...

Determination of Suitable Areas for underground Dam Construction Using Boolean and Fuzzy Logics in Central Areas of Ardebil Province

In the arid and semi-arid area's rainfall have considerable changes in terms of time and amount that make the water resource management an important issue. In this research, using both Boolean and Fuzzy logic were zoned potentiality suitable areas for construction of underground dams. The study area is located in the central region of Ardabil province with 7461 km2 area and semi-arid climate. F...

An AHP-Delphi Multi-Criteria Decision Making Model with Application to Environmental Decision-Making

Feasibility study and construction of an underground dam in the Daryan watershed (Case Study Mashnaq Underground Dam)

    The water crisis in arid and semi-arid regions is a limiting factor for human activities and sustainable agricultural development. One of the new solutions in this field is the construction of underground dams. Underground dams compared to conventional dams that store river water in open reservoirs; block the subsurface flow of water in the cross-section of the river and store it under the ...

prioritization of suitable axes for underground dam construction in the doostbeiglou watershed

extended abstract introduction water resources management in arid and semi-arid areas is very important to provide of water for stakeholders. in recent decades, construction of underground dams have been considered, because of its advantages. these dams have many advantages, e.g., unlike a surface dam, land is not submerged to store water and there is no danger of breaching due to natural or ma...

APPROXIMATE ALGORITHM FOR THE MULTI-DIMENSIONAL KNAPSACK PROBLEM BY USING MULTIPLE CRITERIA DECISION MAKING

In this paper, an interesting and easy method to solve the multi-dimensional  knapsack problem is presented. Although it belongs to the combinatorial optimization, but the proposed method belongs to the decision making field in mathematics. In order to, initially efficiency values for every item is calculated then items are ranked by using Multiple Criteria Decision Making (MCDA).  Finally, ite...
