Groundwater Management in Coastal Area of Batang Regency to Anticipate Sea Water Intrusion

Abstract

Of the water sources that exist on earth, almost all of human’s daily water needs such as drinking, bathing and washing are sourced from groundwater. Uncontrolled extraction of groundwater can cause various impacts on the environment, such as lowering of the groundwater level and seawater intrusion. Efforts to manage groundwater need to be carried out so that its availability is always maintained. The initial step of this effort is to formulate a management model as a basis for policy determination. For this reason, in this study a dynamic modeling simulation was carried out using dinamic program. The results of the research show that the priority for groundwater management efforts in the coastal area of Batang Regency is to reduce the use of groundwater for the domestic sector which can be done through saving groundwater use or by increasing the capacity of the local water company. Besides that, management through artificial recharge by making infiltration wells or biopore holes is also effective in maintaining the availability of groundwater in this area.
