ANALYSIS OF GROUND WATER DRAFT PATTERN IN AN AGRICULTURE LAND USE UNDER RAINFED WATERSHED SYSTEM
Journal Title: International Journal of Agriculture Sciences - Year 2017, Vol 9, Issue 4
Abstract
There has been a significant increase in the demand of groundwater for agriculture, domestic and industrial uses. This has caused over exploitation of groundwater in some areas causing excessive lowering of water levels, sea water intrusion in coastal aquifers and upcoming of saline water in inland areas. To overcome from these problems the ground water draft pattern has been studied in the Patapur micro-watershed, which is located in Raichur district [semi-arid region].In the micro-watershed the main source of irrigation has been supplied from the tube wells. The necessary data[discharge of the tube well (lit/s), irrigation period (hr), irrigation interval (days), number of irrigation, crop details, soil types etc]required for the groundwater investigation was collected from the owners of the tube wells. Parallelly, the groundwater fluctuations during pre-monsoon, monsoon and post-monsoon for 2013-2014 were also measured [3-4 m during the month of June and July]. The total groundwater draft during the investigation period was 228,858.50 m3. From the study it was concluded that,t he micro-watershed prevailed with semi arid agro climatic condition needs groundwater protection to set sustained yield of rain fed crop intermittently.
