    Bhargava, D. N.; Chandra, Satish; Mishra, G. C. (National Institute of Hydrology, 1985)
    A mathematical model for seepage studies from two parallel canals has been developed and interference of two parallel canals is studied. One of the canals is situated on ...
  • TN-14 : Flow towards well with storage in leaky aquifers 
    Seethapathi, P. V. (National Institute of Hydrology, 1985)
    The formulation of strategy for the optimal management of groundwater demands a knowledge of the relationship between the pump ages in the wells to the drawdowns in the aquifers both in spatial ...
  • TN-13 : Regional aquifer simulation 
    Seethapathi, P. V. (National Institute of Hydrology, 1984)
    Over the past two decades ground water has become topic of discussion and investigation and as a result the knowledge and understanding of ground water conditions have radically improved. ...
  • TN-12 : Methodology for estimation of design storm 
    Ramasastri, K. S.; Seth, S. M. (National Institute of Hydrology, 1984)
    Estimation of 'Design Flood is a first and vital step in the design process for a large range of water resources development works. The design flood is generally derived from the design storm ...
  • TN-11 : Water requirement of crops 
    Lohani, Vinay K.; Seethapathi, P. V. (National Institute of Hydrology, 1984)
    It has become essential to make effective use of the available water resources allocated for agricultural purposes. Besides better methods of land preparation, proper management of irrigation ...
  • TR-20 : Identification of hydroenvironmental indices 
    Gaindhar, Vipin; Sinha, Asha; Karawade, Deepa; Nanda, N. K. (National Institute of Hydrology, 1985)
    This piece of work is aimed at design and implementation of a Management Information System Package for the employees of National Institute of Hydrology, Roorkee. This utility package computerizes ...
  • TR-19 : Recharge from large depression storage 
    Chachadi, A. G.; Mishra, G. C. (National Institute of Hydrology, 1985)
    The duration of the pumping test is largely influenced by the discharge rate, radial distances of the observation points, aquifer parameters and boundary conditions. Plots have been presented for determining the time ...
  • TN-18 : Parameterization of hydrogeological factors in groundwater study 
    Mishra, G. C.; Chachadi, A. G. (National Institute of Hydrology, 1985)
    Walton has presented a relationship of transmissivity with specific capacity for wells having negligible storage. These graphs are used for estimation of transmissivity provided storage coefficient ...
  • TN-17 : Drought analysis using soil moisture simulation approach 
    Sikka, A. K.; Mishra, G. C. (National Institute of Hydrology, 1985)
    A number of drought indices have been developed in past. Most of these indices appear to be adhoc and consider either rainfall alone or take some account of soil water storage and loss of water from this storage ...
  • TN-10 : Artificial recharge of groundwater 
    Lohani, Vinay K.; Seethapathi, P. V. (National Institute of Hydrology, 1984)
    Development of the groundwater resources in various parts of the world has been increasing in recent years as development of surface water resources approaches the point of full potential. The ...
  • TN-9 : Unsteady flow to a multiaquifer flowing well 
    Mishra, G. C. (National Institute of Hydrology, 1984)
    Using discrete kernel technique, analytical solution has been obtained for unsteady flow to a well tapping any number of aquifers which are separated by aquicludes and have different initial hydraulic heads. ...
  • TN-8 : Study of reach transmissivity for stream aquifer interaction 
    Mishra, G. C. (National Institute of Hydrology, 1984)
    A river comprising boundary of flow domain is often encountered in regional groundwater flow modelling. When a river fully penetrates an aquifer and has considerable stream discharge, the river ...
  • TN-7 : Study of depth-area-duration and depth-duration characteristics 
    Seth, S. M.; Ramasastri, K. S.; Singh, Pratap (National Institute of Hydrology, 1984)
    Some of the extreme storms in the contiguous areas of Saurashtra and Rajasthan forming part of the arid and semi-arid belt in India were analysed by the depth-area-duration and depth-duration ...
  • TN-6 : Estimation of seepage from canal using tracer technique 
    Mishra, G. C. (National Institute of Hydrology, 1984)
    Loss of water due to seepage from irrigation canals constitutes a substantial percentage of the total usable water. By the time the water reaches the field, it has been estimated that the seepage losses are of the ...
