  • SA-2 : Reservoir Operation Studies 
    Yoganarsimhan, G. N. (National Institute of Hydrology, 1983)
    This state-of-art report deals with problems associated with operation of a single purpose/multi-purpose reservoir. Starting with heuristic procedures of reservoir operation, the general ...
  • SA-1 : Time series modelling 
    Kumar, Arun (National Institute of Hydrology, 1982)
    Hydrologic variables might vary in space, as well as time and are represented by either continuous or discrete series. Much of the statistical methodology is concerned with models in which ...
  • RN-49 : Overland flow in mountainous areas 
    Kumar, Avadhesh; Ramasastri, K. S. (National Institute of Hydrology, 1986)
    Runoff in mountainous regions results from rainfall, snowmelt and glacier-melt. The different components of runoff are generally considered to be surface run off, sub-surface runoff and ...
  • RN-48 : Regional approaches for flood estimation in mountainous area 
    Kumar, Avadhesh; Ramasastri, K. S. (National Institute of Hydrology, 1986)
    Floods in mountainous areas are the catchment's response due to precipitation and are influenced not only by catchment and stream characteristics but also storm characteristics and vegetal and land use changes. More ...
  • RN-46 : Snowmelt processes 
    Singh, Pratap (National Institute of Hydrology, 1986)
    The accurate forecasting of the volume of snowmelt runoff likely to occur is of great importance for water resources management, especially to those responsible for operation of multipurpose reservoirs. [he ...
  • RN-45 : Remote sensing application to sedimentation studies 
    Bhar, A.K. (National Institute of Hydrology, 1986)
