Changing trends in annual maximum daily precipitation in central – highland regions in context of climate change

Abstract

     Annual maximum daily precipitation (AMDP) is often used to estimate the design flood for medium and small ungauged-basins. Research on changing trends in annual maximum daily precipitation in context of climate change is to assess and analysis the frequency and magnitude of flood, especially in Central and Highland regions, where the variation of storm and flood are high. The research applied the bias correction methods to simulate the daily precipitation for some raingauge stations in the region from HadGEM3-RA climate model to analysis the trends of annual maximum daily precipitation in time, and applied ArcGIS software to simulate the changing of AMDP in space. The result showed that AMDP tends to decrease in most area.
