  • RN-41 : Analysis of low flow to investigate drought characteristics and plan water use management 
    Verma, P. K.; Sikka, A. K. (National Institute of Hydrology, 1986)
    In spite of the lack of a unified definition of drought among the community of scientific professionals, it is basically agreed to be a situation of prolonged water deficit for given use, caused due to ...
  • RN-40 : Comprehensive review of drought indices 
    Sikka, A. K. (National Institute of Hydrology, 1986)
    Scores of drought definitions are available in the literature developed by a variety of disciplines because it affects so many economic and social sectors. Drought holds different connotations to different people. The ...
  • RN-39 : Remote sensing applications for flood inundation studies 
    Bhar, A.K. (National Institute of Hydrology, 1986)
    Mankind is beset with flood problems from the very ancient time. Fury of flood leaves its crippling effect on the economy. Flood inundation is one of the basic data need to understand, combat ...
  • RN-38 : Measurement of snow and estimation of snow cover 
    Singh, Pratap (National Institute of Hydrology, 1986)
    The rivers draining out of the Himalayan region derive a major portion runoff from snow and ice melt. For runoff forecasting, irrigation planning, supply of drinking water and industrial use etc. reliable and ...
  • RN-37 : Hydrological aspects of droughts 
    Singh, R. D. (National Institute of Hydrology, 1986)
    Drought forms one extreme end of the hydrologic cycle. It represents a period of abnormally dry weather sufficiently prolonged for the lack of precipitation to cause a serious hydrological imbalance and connotations of ...
  • RN-36 : Vegetation management for increased water yield 
    Sikka, A. K.; Lohani, Vinay K. (National Institute of Hydrology, 1985)
    Studies done in India and elsewhere have indicated that the vegetation management practices have a great potential in increasing water yield from a watershed. The vegetation management practices include ...
  • RN-35 : Flood foresting models 
    Seth, S. M.; Goel, N. K. (National Institute of Hydrology, 1985)
    A hydrological forecast is the prior estimate of the future state of hydrological phenomena based on the knowledge of underlying physical laws and the modifying effects of specific geographic conditions. The ...
  • RN-34 : Conjunctive use of surface and ground water 
    Kamal (National Institute of Hydrology, 1985)
    In a general sense, factors that must be considered in conjunctive use analyses have been identified and discussed. The factors have been distilled from the work of many authors who have examined ...
  • RN-33 : Atmospheric general circulation models 
    Ramasastri, K. S.; Singh, Pratap (National Institute of Hydrology, 1985)
    Hydrological cycle encompasses in itself two major processes the atmosphere phase and the ocean-land surface phase. Mathematical and conceptual modelling of these two processes independently have been ...
  • RN-32 : Telemetry systems and signal analyzers for data transmission 
    Goyal, V. C.; Seth, S. M. (National Institute of Hydrology, 1985)
