The researchers used electrical resistivity surveys to evaluate the underground water in Gashua, Yobe State. They found that the aquifer in the area has good water flow capacity and can hold a decent amount of water. The thickness of the aquifer ranged from 66.7 to 120 meters, with an average of 84.32 meters. The water in the aquifer has a resistivity ranging from 100.7 to 350 ohm-meters, with an average of 280 ohm-meters. The water flow rate through the aquifer ranged from 110.91 to 348.88 square meters per day, with an average of 182.55 square meters per day. The porosity of the aquifer, which is how much water it can hold, ranged from 27.7% to 32.9%, with an average of 28.8%. Overall, the study shows that Gashua has a good potential for groundwater production.
