Study and Analysis of Groundwater Level Variation in Catchment of Bambela Check Dam on Rivel Machhan Dr. N. J. Shrimali Department of Civil Engineering Faculty of Technology & Engg., The M.S.University of Baroda Vadodara, Gujarat, India

Abstract Continuous exploitation of groundwater and its increased use has created issues related to recharging. Water harvesting and recharging of ground water is gaining greatest important amongst many issues related to water resources management. Water harvesting by construction of check dams is one of the very popular approach which is at many places practiced through people’s participation. Dahod district of the Gujarat state is a tribal area. It is a water scarce area with average annual rainfall around 900 – 1000 mm. Water harvesting by construction of check dams is practiced in this area. After construction of check dams scenario started changing and significant improvement in the water table conditions observed. Here an attempt is made to study water table fluctuations in catchment of one of the check dam named Bambela Check Dam on river Machhan.

INTRODUCTION

Dahod district is located in the North-east direction of Gujarat. Machhan river is flowing through Jhalod taluka. The overall 2

topography of the region is highly undulating and of varying slopes. The catchment of the river is 431 km up to its meeting place with Anas which is a tributary of Mahi. Machhan river catchment receives much of its rainfall from the southwest monsoon during the period between June and September, its maximum intensity being in the months of July and August. The annual rainfall in the area varies between 800 to 1000 mm. Bambela check dam is 100 m long and 3.5 m. high. Following Table 1 gives salient features of Bambela check dam.
