  • 3-Leaching for Salinity Control. 
    Pandey, R. S.; Tyagi, N. K. (National Institute of Hydrology, 1988-12)
    Leaching is an important tool for reclamation of saline lands and their management in post drainage phase. Research advances in India in respect of theoretical developments, methodology and design practices of leaching ...
  • 4-Modelling Soil Water Dynamics in Unsaturated-Saturated Zone. 
    Saini, Ashok Kumar; Singh, Sita Ram (National Institute of Hydrology, 1988-12)
    Richards equation with a sink (source) term adequately describes the dynamics of water in unsaturated-saturated soil-aquifer system. Galerkin's finite element method in conjunction with the iterative predictor-corrector ...
  • 5-Hydraulic Performance of Deep Horizontal Tile Drainage System. 
    Kumar, Ranvir; Singh, Joginder; Agarwal, M. C. (National Institute of Hydrology, 1988-12)
    The hydraulic performance of deep tile drainage system was evaluated in saline rising water table area. The tiles were laid at a depth of 2.5 m below land surface with 24, 48 and 72 m spacings. The q vs h relationship ...
  • 6-Drainage and Water Logging Problems in India. 
    Briz Kishore, B. H. (National Institute of Hydrology, 1988-12)
    In the absence of any means of draining the irrigated water adequately, the water table begins to rise. Seepages from canals, tanks. irrigation fields, etc. further add to water table, which ultimately reaches the ...
  • 7-Surface Drainage System for Agricultural Watershed. 
    Mishra, G. C.; Soni, B. (National Institute of Hydrology, 1988-12)
    The suitability of surface drainage system, the hydrological parameters needed for design of surface drainage system, updating of SCS curve number and the SCS method for computation of design discharge during successive ...
  • 8-Drainage of Heavy Soils. 
    Sahni, B. M. (National Institute of Hydrology, 1988-12)
    Heavy clay soils (Vertisols and associated soils) constitute a major group of soils in India. Because of their clayey nature, these soils are highly moisture retentive and hence possess high potential productivity with ...
