  • TR-17 : Simple techniques for forecasting of monsoon rainfall and runoff and application to Mahanadi river at Hirakund 
    Goel, N. K. (National Institute of Hydrology, 1986)
    Monsoon period (June to Oct.) is a crucial period as nearly 90% of annual rainfall and runoff is received during this period in Indian subcontinent. The water resources planning activities e.g. . ...
  • TR-16 : Overland flow modelling 
    Palaniappan, A. B.; Ramasastri, K. S. (National Institute of Hydrology, 1986)
    Surface flow estimation is needed by planners and managers of water resource system. Most of the analysis are based on linear systems, wherein the watershed is assumed to be virgin. But, ...
  • TR-15 : Mathematical modelling of moving storms 
    Ramasastri, K. S. (National Institute of Hydrology, 1986)
    The magnitude of peak flood and the shape of a flood hydrograph depend not only on the magnitude of total storm rainfall depths but also on its distribution in space and with ...
  • TR-14 : Estimating evaporation losses from lakes and reservoirs 
    Sikka, A. K.; Goyal, S. K. (National Institute of Hydrology, 1986)
    Engineers, planners and all concerned with water resources require an estimate of evaporation losses from lakes and reservoirs for the efficient reservoir operation and the water balance ...
  • TR-13 : Development of a variable parameter simplified hydraulic flood routing model for rectangular channels 
    Perumal, M. (National Institute of Hydrology, 1986)
    A variable parameter simplified hydraulic method based on the approximation of the St. Venant's equations which describe the one dimensional flow in a channel or river has been developed for routing floods in channels ...

  • UM-10 : Muskingum cunge routing procedure 
    Seth, S. M.; Palaniappan, A. B. (National Institute of Hydrology, 1984)
    Experience and observations of flood flows in river show that the flood peak attenuates as it travels downstream. Although lateral flow and flow from tributaries may add up to the flow and lead ...
  • UM-9 : Model parameter evaluation using catchment characteristics 
    Seth, S. M.; Singh, R. D. (National Institute of Hydrology, 1984)
    In view of growing development of water resources in many projects, it becomes necessary to estimate discharge values for ungauged watersheds or sites within a region. The simplest way is to ...
  • UM-8 : Unit Hydrograph Derivation 
    Seth, S. M.; Singh, R. D. (National Institute of Hydrology, 1984)
    The unit hydrograph technique is a simple tool being used by most of the water resources development organisations for the estimation of flood flows. Although number of techniques are available ...
  • UM-7: Finite Element Aquifer Flow Model 
    Seethapathi, P. V. (National Institute of Hydrology, 1984)
    The purpose of this report is to describe how to model aquifer systems with AQUIFEM-1, a finite element aquifer flow model developed by Massachusetts Institute of Technology and implemented at the Institute for ...
  • UM-6 : Preparation of Working Table 
    Seethapathi, P. V.; Dhason, S. R. B. (National Institute of Hydrology, 1984)
    A computer model is presented for quantifying the impacts of multipurpose water management policy. The model is designated for analysis of water availabilities throughout a river basin over extended ...
  • UM-5 : Rating curve analysis 
    Seth, S. M.; Palaniappan, A. B. (National Institute of Hydrology, 1984)
    The water level and the volume of water passing a site in a river provides useful information about the flow, which can be used for many planning purposes. The water levels are easily observed and ...
  • UM-4 : Polynomial Regression 
    Seth, S. M.; Goel, N. K. (National Institute of Hydrology, 1984)
    For any non linear function Y=f(X) regression may be obtained by fitting a polynomial. The general form of the polynomial regression is as given under:- Y = a o + a + a + + ...
  • UM-3 : Multiple Linear Regression 
    Seth, S. M.; Goel, N. K. (National Institute of Hydrology, 1984)
    The derivation of relationships among hydrologic variables is of great importance for the transfer of information from few gauged sites to many ungauged sites. This relationship may be between ...
  • UM-2 : Frequency analysis 
    Seth, S. M.; Goel, N. K. (National Institute of Hydrology, 1984)
    The user's manual gives the details of a computer programme for best fit distribution using normalization procedures and chi-square criterion. Various normalization procedures which have been used in the ...
