Abstract:
The Vu Gia - Thu Bon river basin is one of the largest basins in Vietnam. Research and assessment of this potential basin is a great interest to scientists and regulators. One of the important studies is the evaluation of morphological parameters of the basin. The morphological parameters represent water resources and at the same time are one of the factors that help researchers give a comprehensive view of the basin, assessing the factors related to the direction of the flow, the flow rate or hazards throughout the basin. Therefore, this paper is an attempt to evaluate the morphology of Vu Gi

Abstract. Hydrological droughts are one of the most damaging disasters in terms of economic loss in central Vietnam and other regions of South-east Asia, severely affecting agricultural production and drinking water supply. Their increasing frequency and severity can be attributed to extended dry spells and increasing water abstractions for e.g. irrigation and hydropower development to meet the demand of dynamic socioeconomic development. Based on hydro-climatic data for the period from 1980 to 2013 and reservoir operation data, the impacts of recent hydropower development and other alteration

Flood is one of the most well-known phenomena in the Central Vietnam where Da Nang city is located. As the most area in the central coastal part, this city frequently suffers to flood without any prevented structure like sea dike or river levee. The only thing that can help to the response for flood is emergency plans. Therefore, flooding still causes great damages to the economic development and social stability in this region. For ensuring the sustainable development of Da Nang city under the impacts of climate change and sea level rising, it requests a change in direction of the solution, f

Abstract Upstream hydropower development has a great impact on downstream flows. According to the Regulation of Multi-reservoir Operation in Vu Gia – Thu Bon River Basin (Regulation 15371), four large-scale upstream reservoirs must discharge certain flow during the dry season to increase water levels at downstream hydrological stations named Ai Nghia and Giao Thuy. These stations are used as the control points for the downstream water supply.
