  • 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 ...
  • नदियों को जोड़ने की चुनौती
