Dam site selection is an important task in water resource management and it depends on a number of biophysical as well as socio-economic factors. Dam site selection is becoming important research area due to the increase of water scarcity and also to prevent flood in certain area. This paper presents Multi Criteria Decision Making (MCDM) approach in water resources management through the integration of Analytic Hierarchy Process (AHP) and Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS). These methods were applied for identification of suitable dam site in Tlawng sub-basin. The influential criteria for dam site selection were initially identified through literature review and experts opinion which was followed by the selection of four (4) feasible sites after having studied Tlawng watershed. Lastly, AHP and TOPSIS were applied to determine the relative weight and rank respectively.

Water management has become an important research area as the scarcity of water increases day-by-day around the world. Rain water harvesting is one of most efficient way of managing water resources which could be utilized for different purposes during the needy period such as drought, drinking water and irrigation. This paper presents a method for identification of suitable dam site using both Multi-Criteria Decision Analysis (AHP) and GIS to establish the hydrological characteristics of suitable region for dam construction. This method considers six (6) criteria such as slope, size of catchment, geology, land use characteristics, proximity to settlement and proximity to river. Each criterion was assigned a weight depending on relative importance with other criteria. Thematic layers were then generated based on these criteria and overlaid in GIS environment to obtain layers identifying the suitable sites for dam construction.

Subsurface dams and aqueducts have been used for many years as important sources of water in different parts of the world. Nowadays, little attention is paid to aqueducts. On the other hand, there is a great tendency for constructing and using subsurface dams in many arid and semiarid parts of the world such as Iran. A combination of these two structures was established in ancient Iran including Qanat Vazvan in Isfahan. Nowadays, new methods and techniques such as the Geographic Information System and Remote Sensing have been developed to process site selection of subsurface dams with high accuracy and in a short time. Study and research of the Qanat Vazvan structure emphasizes the idea that these two structures have been combined in a new way. Considering some main criteria and sub-criteria for subsurface dam site selection, with the existence of aqueduct, some suitable locations with a combination of aqueduct and subsurface dam in Pishkoh basin, Taft, Yazd province have been delineated. Some of the advantages of underground dams are their local use, being close to the demand sites and their capacity for gathering water in each season. These positive points when combined with reclamation of aqueducts (qanats) cause a renewable situation for qanats and their efficiency as a water resource management process. Underground dams can be built in a qanat's shaft by constructing some hatches inside the dam's wall. Hence, water can be stored during cold rainy seasons. The main and basic weaknesses of qanats can be covered through this combination. Hence, it causes a strong and optimum usage of qanat water.

AbstractUnplanned and haphazard built-up growth due to immense pressure of population is a common problem for maximum cities of developing countries which paves to create urban sprawl by capturing spacious areas of natural environment. For this, selection of suitable places for built-up development by maintaining ecological balance has become inevitable part for proper urban planning. Siliguri planning area, which has witnessed a tremendous growth in built-up features after the 1990, has been chosen for this work to find out best places for future built-up development with minimum effects on different natural features and also calculates the amount of different types of suitability which will be transferred from different land use and land cover categories in near future which is a novelty of this work. The work has been executed through GIS-based multi-criteria analysis, and a total of nine criteria have been taken to locate best places for built-up development. Analytic hierarchy process or AHP has been used to calculate weights of each criterion by using pair wise comparison matrix. Final site suitability map has been prepared with four different classes: high suitable, moderate suitable, less suitable and restricted area and the percentage of land is high in moderate suitable category that is 52.33% which covers the intermediary portion, mainly wastelands and agricultural land of the study area with higher facility of accessibility. Results from this work would be helpful for the planners, stakeholders, policy makers by identifying best locations for the intensive developmental projects in near future.
