    Khobragade, S. D.; Bhar, A. K. (National Institute of Hydrology, 1992)
    The earth land is dotted with about three million lakes, most of them being located in Northern Hemisphere. Many times lakes, ponds and reservoirs are wrongly considered as simile but ...
  • TN-91 : Stochastic modelling of water quality data 
    Tyagi, Aditya (National Institute of Hydrology, 1991)
    In the past two decades, many mathematical water duality models have been developed to simulate physical. chemical. and biological processes occurring in river water. Their possible ...
  • TN-79 : Estimation of evapotranspiration losses from agricultural lands- climatological approach 
    Goyal, S. K.; Raghuwanshi, N. S. (National Institute of Hydrology, 1990)
    Evapotranspiration from agricultural lands forms an important part in the root zone water balance study. For last few years due to continued occurrence of drought conditions, it has become ...

  • TN-72 : Review of methodologies and software for flood forecasting 
    Jain, S. K. (National Institute of Hydrology, 1990)
    Flood forecasting is required for a number of purposes, e.g. , flood control, flood damage reduction, and reservoir operation. Significant improvements in operation of water resources systems ...
  • TN-71 : Use of paleoflood information in frequency analysis 
    Seth, S. M. (National Institute of Hydrology, 1990)
    The study of past or ancient flood events which occurred prior to the time of human observation or direct measurement by modern hydrologic procedures, is termed as paleoflood hydrology. ...
  • TN-70 : Long range forecasting onset of drought condition in tropics and sub tropics 
    Divya; Sharma, M. K. (National Institute of Hydrology, 1989)
    Droughts of great magnitude in various tropical and sub-tropical regions have been a matter of concern in the recent past. Their socio-economic consequences have resulted in the studies ...
  • TN-97 : Acid rain and its implications 
    Divya (National Institute of Hydrology, 1992)
