Identification of suitable location for construction of check dam in Manur water shedding area, Tirunelveli District

In this research article author has focused on the issue of ground water and narrated that in modern civilized society the day today usage of ground water for community utility has been raised. As it is clear that due to change in weather condition the predicted monsoon has been changing its seasonal annual rainfall. Furthermore, the it is suggested that a proper technique should be implemented to preserve the available fresh water, which is need of the hour for dry zone like Manur of Tirunelveli district. A suitable techniques has been suggested for real time implementation which is to be demonstrated in a pilot scale. This research work explores all the possibilities to execute the identifi cation of suitable site selection.

Introduction
Rural development, Urbanization and industrialization are developing in modern era with the support of available ground water. Conservation of water resources is a global issue, which has been emerging as a diffi cult task in the developing countries.
Tirunelveli is established with good water resources from the origin of river thamirabarani, meanwhile manur taluk has been observed to be dryzone with lesser water storing capability [1]. Considereing the fact it is planned to raise the ground water storage with the support of identifying suitable location for the construction of check dams in the region, where the draing excess river water may be preserved. While focusing on geological parameters in these areas it has clay soil also called as black cotton soil, which has a very good potential to store ground water [2]. The real need for the dry zone is adopting a suitable technique for water conservation implemention.
In recent days construction of sub surface dam has been emerging in most part of the world for temporary storage of groung water, which may be utilized for cattle feeding and day today utility [3]. The most crucial part in this work is identifi cation of location, where a vast parameters are to be typically considered for fi xation. Comparatively it is assessed that each area has unique quality with distinguished advantages and disadvantages, but priority is given for the possibility of reducing the evaporation potential of water [4].
Multi-Criteria Decision-Making Method (MCDM) works on the principle of choosing different criteria and each paramaters have been measured in terms of quantity and quality. The major factors took into considerations are earth study, hydro geological study and fi nancial contribution, meanwhile they have been given weightage and based on optimization suitable region is fi nalized [5]. In this project work, 14 different locations 047 https://www.peertechzpublications.com/journals/global-journal-of-ecology Citation: Gopikumar  Outcome from different ELECTRE have been categorized and ranked, further they may be merged with Borda and Copeland approach.
Finally this project work will give a solution for the preservation of shedding freshwater to the sea with more detailed fi eld investigations and manur taluk is always identifi ed as the best study location based on GIS information.

Literature survey
Subsurface dams or check dams are normally constructed to safeguard the available water resource within their limit [6]. In general the purpose of these check dams are to provide   The investigations are carried forward with the geological comparision from spatial database, hydrological assessment with the support of study on hydraulic parameter. The study region has been quantitatively and qualitatively ranked and optimization study has to be progressed with the MCDM analyses. A typical scheme on construction of subsurface dam has been portraited in Figure 3. The parameters required for ranking are highlighted in Figure 4.
The existing river fl ow towards the watershed area is blocked and an artifi cial storage unit creation will benefi t the community. In this case through an external well may be constructed to draw the stored water, which may be used for a long time during change in weather conditions and this will be an effective practice. With appropriate ground truthing study in the location the modern engineering parameters highlighted in the Figure 4 gives easy solution for categorization and rankings are fi xed .
