摘要：Water supply is closely related to geographical and climatic factors on the watershed area. Tank model is one of the hydrological models used to analyze the characteristics of river flow using the data of rainfall and climate. This study was aimed to analyze the flow rate by using a tank model, which can describe the magnitude of hydrological processes, namely runoff rate, infiltration capacity, and ground water content in the sub-watershed of Konaweha. The study site was on the catchment area of ??the Wawotobi dam of Konawe Regency, South East Sulawesi Province, Indonesia. The study results showed that the conservation activity on the catchment area of the Wawotobi dam have a role in increasing the river flow rate and water infiltration into the soil. The pattern of land management that involves the conservation aspects resulted in a lower runoff or discharge rate, a greater value of infiltration and ground water content that can fill into a greater depth. In this case, the land use that takes into account the conservation aspects is very important in keeping the interval between maximum and minimum discharges or river flows, that is, not too big flow. This model of tank can also be used to predict the river flow at various watershed land uses on the sub-watershed area of Konaweha.
