Sustainable groundwater management based on groundwater basin (GWB) must be equipped with comprehensive information including the characteristic of hydrogeology. This management method is very useful for governments to design some regulations, such as tax and conservation zone. Nowadays, not only the government but the public society can also have access to know this management. Open and transparent groundwater application needs sufficient data. Based on that issue, this research aims to provide the geological and hydrogeological conditions of GWB, define the aquifer configurations, and determine the groundwater recharge-discharge zones and the type of GWB boundary on Karangkobar GWB. The methods applied to the study are 1) mapping the geological and hydrogeological condition; 2) reconstruction of subsurface stratigraphic condition; and 3) overlay four parameters of the recharge-discharge zone. The Karangkobar GWB consists of the unconfined and confined aquifer of High Plain Aquifer, where the groundwater flows from north and east heading southward and westward. Seven boundary types bounded the Karangkobar GWB. The map can also support the open and transparent water data application system, it will also ease the party that will conduct an assessment to design regulation regarding the groundwater management.
Key words: groundwater basin / boundary type / Karangkobar / recharge zone
