  Tandale, T. D. (National Institute of Hydrology, 1987)

  The paper presents results of hydrogeological studies carried out in two representative river basins of upland Maharashtra. These results are well comparable to other river basins ...
• 5-Ground water simulation for planning salinity management. 

  Tyagi, K. C.; Pillai, N. N.; Tyagi, N. K. (National Institute of Hydrology, 1987)

  Secondary salinization due to rise in water table is a growing problem in parts of Sirsa and Hisser districts of Haryana. Projections of waterlogged area made through simulation studies indicated that of the ...
• 6-Unsteady flow to a well in multiple confined aquifers. 

  Singh, Sita Ram (National Institute of Hydrology, 1987)

  Transient ground water flow to a fully penetrating well installed in n-confined aquifers (n is an integer) separated by aquicludes has been analysed. The aquifers were in hydraulic equilibrium before the start ...
• 7-Determination of aquifer recharge for varying river stages. 

  Mishra, G. C. (National Institute of Hydrology, 1987)

  A mathematical model has been developed for finding the exchange flow rate between a river and a multiaquifer system for varying river stages. The solution has been obtained by discretising the time parameter and using ...
• 8-Trade off between accuracy and grid sizes in a groundwater management model. 

  Laxminarayana, V.; Nagaraj, M. K. (National Institute of Hydrology, 1987)

  In water resources systems, most of the models are optimum simulation type in which management of resource is the main objective. Generally groundwater management models use governing partial differential equation ...
• 9-Groundwater induced inundation in the Pandarethu mines of Malabar cements limited. 

  Prasad, P. M. R.; Rajagopalan, S. P. (National Institute of Hydrology, 1987)

  This paper is concerned with detailed investigations which were carried out in the Pandarethu mines of Malabar Cements limited to obtain quantitative estimates of groundwater induced inundation in the mine pit. A ...
• 10-Correlation of unit draft of electric tubewells and irrigation requirements of crops in selected areas of Punjab - A case study. 

  Singh, Gurucharan (National Institute of Hydrology, 1987)

  There are about 0.5 million private shallow electric tubewells in Punjab State. The farmers are charged by a flat rate for consumption• of electricity by agricultural pumpsets.There is tendency amont the farmers ...
• 11-Use of shallow tubewells for skimming and anti water logging. 

  Dhillon, G. S.; Paul, D.; Kumar, Mahinder (National Institute of Hydrology, 1987)

  The waters in the south western part of the state of Punjab are suitable for irrigation in its upper zone up to about 15 metres and deeper water is saline. To utilise these brackish waters ...
• 12-Vertical drainage for reclamation of saline land. 

  Naorem, Achoubi D.; Kazmi, H. A. (National Institute of Hydrology, 1987)

  Well drainage is an alternative method to gravity drainage. A brief account of the problems of salty soils, their origin, occurrence, and reclamation are given. Some theoritical and practical ...
• 13-Ground water data storage and retrieval system. 

  Chalisgaonkar, Deepa; Jain, Sharad K.; Parida, B. P. (National Institute of Hydrology, 1987)

  Management of large volumes of ground water data observed under variable exploitation and replenishment conditions needs a scientific basis for mass storage alongwith facilities for selected retrieval. A ...
• 14-Experience with nucleonic snow gauge. 

  Kumar, Virendra (National Institute of Hydrology, 1987)

  Nucl6onic Snow Gauge has been used for the first time in India for measurement of water equivalent of snow cover at a snow course in BEAS Basin. The gauge consists of CS-137 sources, NaI(Tl) detectors and gamma ...
• 15-Fabrication, Testing and Evaluation of a rainfall simulator. 

  Adhikari, R. N.; Rao, M. S. R. M.; Chittaranjan, S.; James, E. V. (National Institute of Hydrology, 1987)

  Information on soil loss under different slopes, vegetative covers and rainfall characteristics are not available in order to make specific recommendation for a particular region. This information ...
• 16-Design requirements for installation of lysimeters. 

  Singh, Raj Vir (National Institute of Hydrology, 1987)

  For accurate and reliable measurements of different components of crop hydrologic cycle the lysimeters should be constructed, installed and operated properly. The installation of lysimeters must meet several design ...
• 17-Fabrication, Testing and Evaluation of Bellary type water level recorder. 

  James, E. V.; Chittaranjan, S. (National Institute of Hydrology, 1987)

  Automatic water level recorders are essential in the soil and water conservation and hydrological research. There is an urgent need to design and fabricate indigenous recorders, eliminating some of the ...
• 18-Moisture inflow over India and its contribution to rainfall during normal, good and bad monsoon years. 

  Dewan, B. N.; Subramanian, S. K.; Dikshit, S. K. (National Institute of Hydrology, 1987)
