Restoration of Minor Irrigation Tank Using Geophysical Methods in Deccan Traps – A Case Study in Sawangi, Amravati District, Maharashtra
Journal Title: International Journal of Engineering and Science Invention - Year 2018, Vol 7, Issue 7
Abstract
In watershed areas the groundwater management can be solved by building irrigation tanks to sustain from drought and improve crop yield. The minor irrigation tanks can also supply water for drinking purpose. When the tank is full to its capacity during the rainy season, it should be able to supply water both for irrigation and drinking purposes even during the dry season. Any leakages in the subsurface of the tank would result in seepage of water into the ground and the tank would be dry during the summer months. An attempt has been made to identify the leakages in a minor irrigation tank using geophysical methods, which would enable to study not only the leakages but also the flow direction of the leakages along fractures or joints in the tank. This can lead to improved sustainability of the minor irrigation tank during the dry seasons. A detailed geophysical investigation has been carried out on minor irrigation tank located in village Sawangi, Warud taluka, District Amaravti, Maharashtra, India. In this area a large number of minor irrigation tanks have been constructed for groundwater management. One tank located in the area with a storage capacity is 521 Mm3 and water spread area is 37 ha has been chosen for the present study. The average normal rainfall of this area is 710 mm. During the rainy season when the rainfall in the area is normal or above normal the tank attains a full capacity. Subsurface leakages were observed in this tank and it was found that water was draining and the tank was not able to sustain its capacity during the summer months. The leakages were detected in the upstream direction and the downstream direction of the tank. Geophysical studies using Electrical resistivity, Self-potential and VLF EM surveys were carried out to detect the leakages. The fractures zones were identified to be oriented in NW-SE direction in the massive basalt formations and accordingly measures were taken to plug the leakages. This paper presents the applicability using geophysical studies for detection of leakages in minor irrigation tank with a case study.
