    Thandaveswara, B. S. (National Institute of Hydrology, 1988)
    Flood damage computations in case of rare events in urban areas is an important step in Flood Management. In this paper the difficulties, limitations of the current approaches for evaluating the ...
  • Theme-4-5-Impact of 1987 flood on FCD projects. 
    Shahjahan, M.; Hossain, A. N. H. Akhtar (National Institute of Hydrology, 1988)
    The flood of 1987 was a very remakable one in respect of its magnitude and the damage it has done to the national economy of Bangladesh. The said flood has exceeded the flood of 1974. In ...
  • Theme-5-1-Structure of a system for on-line flood forecasting. 
    Corradini, Corrado; Melone, F.; Ubertini, L. (National Institute of Hydrology, 1988)
    A complete system for real-time flood forecasting in large river basins is presented. It was tested on a large Italian basin with a drainage area of 4147 km2. The experimental network, based on the ...
  • Theme-5-2-Flash floods and their forecasting - A few case studies. 
    Singh, Ranjit; Alda, K.; Bhosale, S. G. (National Institute of Hydrology, 1988)
    Flash floods occur from heavy rainfall and sudden overflowing of rivulets and streams into the low lying areas. They occur (i) from the movement of depressions/cyclonic storms (ii) the shift of ...
  • Theme-5-3-Multi-day stream flow forecasting using the Kalman filter model. 
    Fitch, Murray; McBean, Edward (National Institute of Hydrology, 1988)
    The performance of a river flow forecasting model employing a Kalman Filter algorithm is evaluated for increasing forecast times. The expected decrease in forecast accuracy is quantified and ...

  • Theme-5-5-Forecasting of river flows using a CARMA model. 
    Udayasen, Nattawuth; McBean, Edward (National Institute of Hydrology, 1988)
    The Contemporaneous Autoregressive Moving Average (CARMA) model is used to forecast flows of the Ping and Nan Rivers in Thailand. Streamflow forecasting is executed for one year ahead. The ...
  • Theme-5-6-Real time flood forecasting using hydrometeorological model. 
    Wasimi, Saleh A. (National Institute of Hydrology, 1988)
    A conceptual hydrometeorological model suitable for use in real-time flood and flash flood forecasting has been developed. The model has three basic components: the rainfall forecasting model, the ...
  • Theme-5-7-Flood forecasting for the lower Indus river. 
    Phien, H. N.; Austriaco, N. C.; Pornprasertsakul, A. (National Institute of Hydrology, 1988)
