Authors: Tran, Thuc; Co-Author: 2010 (This study investigates impacts of climate change on water resource in the Huong River basin in the Central Vietnam. Hydrological responses of six climate change scenarios were calculated. Results reveal that climate change would cause significant increase in rainfall in wet season resulting in an increase in river flow. By contrast, the decreasing trend of river flow in dry season is a consequence of the decline of rainfall and increase of evapotranspiration under most scenarios. Sea level rise coupled with the lowering of river stages may exacerbate salinity intrusion. Impacts of climate change on socio-economic sectors such as agriculture, tourism, biodiversity, fishery and aquaculture are assessed, and adaptation options for Thua Thien - Hue Province are proposed.)
Authors: Trần Hồng, Thái; Co-Author: 2011 (In recent decades, the increasing in greenhouse gas emission has caused global warming leading to many adverse changes of the environment especially the sea level rise and the hydrological regime. The Dong Nai river basin having the downstream part below the sea level is among the most vulnerable basins to climate change. Recents studies showed that the sea level in the downstream of Sai Gon - Dong Nai river basin is rising. Many cities downstream of the basin especially Ho Chi Minh city are being flooded in flow tides which seriously affect the socio-economic development. Thus, research on the future impacts of climate change on flooding in this area is of vital importance. This paper applied the HydroGIS modeling package to predict the flooding levels in the Dong Nai river basin for the period from 2020 – 2100 taking into account the impact of climate change. Inundation maps were developed based on three climate change scenarios namely B1, B2 and A1FI and different sea level rise values (e.g. 15, 25, 50, 75 and 100cm). These maps together with comprehensive analysis on the trend and extent of flooding will assist decision makers in developing mitigation measures coping with flooding in the river basin.)
