Groundwater resources is affected by natural and socio-economic
factors such as: extending of agriculture area, deforestation, socioeconomic development, environmental pollution, natural disasters, and
climate change that prevent the percolation and infiltration process and
quality of groundwater [1]. Nowaday, these factors are rapidly changed
combined with the negative impacts of climate change have an direct
influence on groundwater resources and an indirect influence on
groundwater users [2]. Infact in coastal Center of Vietnam, freshwater
storage that can be extracted from shallow aquifer are declined, thus it
effect to living, agriculture production, industry, transportation, and
construction in urban areas and as well as coastal areas[4]. In both
science and practical terms, study on evaluation of declination and
adaptation of coastal aquifers to the needs of water supply under climate
change-sea level rise scenarios which will help decision makers in
planning of water resources allocation and looking for alternative water
resources (if needed)[5].
Gio Linh plain in Quang Tri province is in coastal Center areas with
a coastlines of 15.5km extends from Cua Viet town to Trung Giang ward.
It has two main aquifers are Pleistocene and Holocene aquifer that are
abstracted for living and production water usage. However, groudwater
resources are declined in recently years. The lacking of water supply and
increasing of saltwater intrusion in dry season of 2012-2013 due to the
changing of rainfall that affect to the storage of water at main water
reservoirs in the province. To identify the science basis for proposed
solutions for rational use and protection of groundwater resources is
important in progress of subtainable development in the region.
Consequently, the disertation of « Study the effects of natural,
environment, and socio-economic condition to groundwater resources in
Gio Linh, Quang Tri taking into account the impact of climate change
and sea level rise » was sellected to study and complete.
