ASESSMENT OF CURRENT STATUS & CAPACITY OF RAINFALL DATA EXPLOITATION FOR FLOOD FORECASTING; AN APPLIED PILOT STUDY IN CHU RIVER BASIN

Abstract

The most important matter of flood prevention is forecasting and early warning to identify optimal or best practical prevention solutions to minimize damages and losses. Therefore, the requirement of increasing the lead time of flood forecasting and early warning at river-basins is highly significant and practical. The present flood forecasting quality mostly depends on the quality of rainfall forecasts and hydro-met monitoring & observation networks in the basins. Improvement of the accuracy of rainfall forecasts is a fundamental problem of the hydro-met sector included in many international and national studies, which is also not expected to be repeated in this report. The study will be focused in an assessment of current status and capacity of rainfall data exploitation for professional flood forecasting in Viet Nam, in which a pilot application study will be carried out to provide forecast bulletins for Chu river in Thanh Hoa province.
