  • RN-10 : Hydrological parameters in drainage studies 
    Mishra, G. C. (National Institute of Hydrology, 1984)
    The understanding of land phase of the hydrologic cycle plays an important role in design of field drainage system. Physical features(topography, geology; soil characteristics) meteorological (temperature; ...
  • RN-9 : Study of hydrogeological parameters 
    Chachadi, A. G.; Mishra, G. C. (National Institute of Hydrology, 1984)
    Frequently, the groundwater modeller faces with the problem of input parameters to-the model. Hydrogeological parameters like hydraulic conductivity, transmissivity, storativity and specific yield form ...
  • RN-13 : Comparative study of components of watershed models 
    Seth, S. M.; Datta, Bhaskar; Singh, R. D. (National Institute of Hydrology, 1984)
