Water sustainability model for estimation of groundwater availability in Kemuning district, Riau-Indonesia

There are rising interests in the utility of groundwater in various aspects, which is capable of triggering problematic issues. The excessive exploitation for anthropologic uses, without regards to aquifer capacity, will decreases the water table as well as capacity of groundwater in the aquifer. This research is aimed to provide aquifer model of underground water by consideration of various environmental factors, with the propensity of being modeled, in an attempt to predict groundwater conditions in subsequent years. The purpose of this research is to forecast water requirements, availability, as well as three-dimensional model of groundwater depth in Kemuning, Indragiri Hilir Regency-Indonesia between 2015 and 2022. Furthermore, various environmental factors, from aquifer profiles to anthropologic demand, are taken into account in the evaluated model, including water requirements, encompassing recharge and aquifer parameters, which consists of storativity and transmissivity. From anthropologic side are domestic requirements, trade, public facilities, agriculture, and livestock. The results show that groundwater availability in Kemuning is to be safe condition, and average difference is 1.06×108 m3/yr. The coefficient of storativity and transmissivity are 16.514 m2/day and 9 897.26 m2/day, respectively, while the average depth was recorded as 2.8965 m to 10.4927 m.
