Authors: Tran Hong, Thai; Co-Author: 2010 (Vietnam-Chinese transboundary river basins play an important role in socio-economic development for both Vietnam and China. The cooperative research on assessment of climate change impact on water resources is necessary in order to maintain and develop water resources, exploit and consume effectively, protect environment and prevent disasters on transboundary river basins. The problems have been paid the attention by scientists and agencies of both countries. This report presents the expressions of climate change impacts on water resources on Vietnam-China transboundary river basins and suggest cooperative content and methodology of the research.)

The study developed climate change (temperature and rainfall) and sea level rise scenarios corresponding to some key emission scenarios, namely A1FI, A2 and B2. Impacts of climate change on main sectors such as water resources, agriculture and tourism were also assessed. These were used as the basis for proposing adaptation measures.)

Authors: Hoang Minh, Tuyen; Co-Author: 2011 (Base on the results of the flow simulated by Mekong River Commission (MRC), combined with Sea Level Rise (SLR) and salinity scenarios by IMHEN, the paper presents impacts of CC on flooding and salinity intrusion in Cuu Long Delta. By 2050, the maximal flooded area which is more than 0.5 m depth can be up to 68.3% of the entire area of Cuu Long Delta. The maximum distance of salinity intrusion increases in the main rivers can reach by 10 km by the middle of the 21st century. The area affected by salinity intrusion at >4‰ occupies 41% area of all Cuu Long Delta and by salinity >1‰ is 59% of natural area.)
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: Tran Hong, Thai; Co-Author: 2011 (Climate change (CC) is one of the most significant challenges facing human beings in the 21st century. CC will seriously affect lives, production and environment worldwide. It also leads to the increasing temperature and one of its consequences is sea level rise, resulting in unpredicted changes of the river flow. This may cause more severe floods, serious drought and water shortage, further to continent of the salinity intrusions and negatively effect on the human’s lives, socio-economic development. In order to assess the changes in flow in Hong - Thai Binh and Dong Nai river basins under influences of CC, in the article flow from two mentioned basins is analyzed under condition of CC. This is important basis to evaluate the effect of CC on other fields relating to water resources. In the article, rainfall-runoff model (MIKE 11 - NAM model) was used to determine the flow in essential locations in Hong – Thai Binh and Dong Nai river basins in the three CC scenarios: A2, B2 and B1 [1].)
Authors: Tran Hong, Thai; Co-Author: 2010 (Rapid socio–economic development leads to a great increase in water demand of many sectors and conflicts between water users. Moreover, studies have warned about serious degree of influence of climate change (CC) on Vietnam, particularly on the water resources. Therefore, assess CC impacts on water balances are very necessary task. The Ministry of Natural Resources and Environment has completed the appropriate climate change scenarios in Vietnam [1]. In this study, water balance results will be presented including three scenarios: high emissions scenario (A2), medium emission scenario (B2), and low emission scenario (B1). The water balanced in Hong-Thai Binh river basin was calculated, which is one of the largest basins in Vietnam. The basin is very complicated: Under the influence of flow regime of international rivers [2], a system of reservoirs and irrigation structures serving diverse purposes, such as of water supply, irrigation, flood control and hydropower [3-5]. MIKE BASIN model was applied to describe exploitation, utilization and to identify the water shortage areas according to the climate change scenarios.)
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.)
