K. Abstract: Underground water occurs in various types of unconsolidate and semi-consolidated formations (Porous Media) and consolidated formations (Fissured Media). Three major units in the hydrogeologic stratification have been identified. N S-tier classification of underground water is also proposed to assist in diverse requisitions for the exploitation of various water types and its role in civil engineering works in India. 1987-01-01T00:00:00Z http://117.252.14.250:8080/jspui/handle/123456789/3323 Title: 2-Groundwater exploration and development in the Vattulukki tribal farm in attappady. Authors: Sundeep, P. A.; Nazimuddin, M.; Rajagopalan, S. P. Abstract: The Vattulukki Tribal Farm is located within the drought prone Attappady Valley in Palghat District. Successful exploitation of groundwater is the key to any developmental programme in the farm. This paper is concerned with aspects related to identification of a potential bore well site within the farm through geophysical surveys, drilling of the bore well and estimation of sustained well discharge and pump setting details through aquifer performance tests. The bore well was found to safely yield about 70,000 litres per day. This developed water source is being presently used for mulberry cultivation and country brick manufacturing which benefits about 50 tribal families who have been settled in the farm. 1987-01-01T00:00:00Z http://117.252.14.250:8080/jspui/handle/123456789/3322 Title: 3-Conjuctive use of surface and groundwater in Chambal command (M. P.) Authors: Chourasia, L. P. Abstract: It is found that due to the advent of high yielding varieties of crops, vagaries of monsoon and other inter-state problems, the tail reaches of canals of the lower Chambal Command are unable to meet the irrigation requirements of the crops even during winter months. So far, out of 2.21 lakh hectares, 1.89 lakh hectares area has been irrigated during the years 1977-80 but due to shortage of water in the Gandhi Sagar dam, the actual irrigated area in years 1982-85 has come down to 1. 25 lakh hectares due to low rainfall in the catchment area of Gandhi Sagar dam. The average quantity of surface water used for the last three years is 0.121 million hectare metres. The total 0.188 million hectare metres water is required to irrigate 2.21 lakh hectares area. Out of this, 1/3 requirement is proposed to be met out of groundwater resources. At present only 0.40 lakh hectares area is irrigated by the groundwater resources in the Chambal Command. In this paper an attempt has been made to utilise the surface water with available groundwater in the Chambal Command area to increase the intensity of irrigation in the Chambal Command, M.P. 1987-01-01T00:00:00Z
