  • 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 ...

    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 ...

    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.
