Abstract: Study is focused water resources in dry season in the lower part of the Red river starting at Viet Tri comprises 11 provinces and cities where there are the most important areas in socioeconomic point of view for Vietnam. This is the dynamic economic zones and water requirement for socio-economic development is very high. Using statistical method based on observed data collected along the river, the computation is carried out in order to assess the attenuation of water resources quantitatively in dry season. Later scenarios of input water resources at the catchment are generated and Mike11 is used to simulate the hydrological regime along the low part of river system in the dry season. Results show that in current decades, under the impact of climate change water resources induced by rainfall reduces significantly that cause many difficulties for supplying water for socio-economic activities in which mainly for agriculture in the catchment. Also socio-economic activities such as deforestation, sand mining and storing and operation of water from reservoirs are mostly affected to water quantity (water level and discharge) at the study areas. The results of simulation can help decision makers to decide the solutions effectively to exploit fresh water for socio-economic development in downstream areas of Red river delta.
