Abstract / Summary:
The Cooperative Research Centre (CRC) for Catchment Hydrology's research program "Flood Hydrology" has the overall objective:
To improve methods for estimating flood risk and the reliability of flood forecasting, and to advance the understanding of catchment similarity and regional behaviour.
Major improvements in the accuracy of flood estimates, and hence flood risk, could be achieved if we could better predict the proportion of storm rainfall which becomes flood runoff. Depending on initial wetness and catchment characteristics, this proportion can vary from 0% (dry catchment, porous soil) to nearly 100% (wet catchment, impervious soil).
CRC Project Dl "Improved loss modelling for design flood estimation and flood forecasting" has the goal of improving the prediction of runoff for storm events. A major factor in the adoption of this project by the CRC is the access to rainfall data (Bureau of Meteorology) and runoff data (Rural Water Corporation). The resulting database is more extensive than has been previously available in Victoria for studies of this kind, and a shining example of the cooperative arrangements within the CRC.
Earlier versions of this review by Nandakumar et al. set the scene for the 3 year project which began in October 1993. This document provides the background and justification for the selection of the sub-projects which comprise CRC Project Dl.
