Ninth International Symposium on River Sedimentation(Oct.18-12, 2004, Yichang, China)

The Ninth International Symposium on River Sedimentation (9th ISRS) has been successfully held on Oct. 18 to 21, 2004 at the site of the partially completed Three Gorges Project on the Yangtze River near Yichang of Hubei Province, China. The Symposium is organized by the Ministry of Water Resources, People's Republic of China (MWR), sponsored by International Research and Training Center on Erosion and Sedimentation (IRTCES), Changjiang River Water Resources Commission (CWRC), China Institute of Water Resources and Hydropower Research (IWHR) and Chinese Hydraulic Engineering Society (CHES). Twenty nine organizations including the United Nations Educational, Scientific and Cultural Organization (UNESCO), International Association of Hydraulic Engineering and Research (IAHR), International Association for Hydrological Sciences (IAHS) and National Natural Science Foundation of China (NSFC) are co-sponsors.

Future hydro-meteorological drought of the Johor River Basin,Malaysia, based on CORDEX-SEA projections

Water scarcity issues in the Johor River Basin (JRB) could affect the populations of Malaysia and Singapore. This study provides an overview of future hydro-meteorological droughts using climate projections from an ensemble of four Coordinated Regional Climate Downscaling Experiments – Southeast Asia (CORDEX-SEA) domain outputs under the Representative Concentration Pathway (RCP) 4.5 and 8.5 scenarios for the 2021–2050 and 2071–2100 periods. The climate projections were bias corrected using the quantile mapping approach before being incorporated into the Soil and Water Assessment Tool (SWAT) hydrological model. The Standardized Precipitation Index (SPI) and Standardized Streamflow Index (SSI) were used to examine the meteorological and hydrological droughts, respectively. Overall, future annual precipitation, streamflow, and maximum and minimum temperatures are projected to change by about ?44.2 to 24.3%, ?88.7 to 42.2%, 0.8 to 3.7ºC and 0.7 to 4.7ºC, respectively. The results show that the JRB is likely to receive more frequent meteorological droughts in the future.
