Developing hydraulic facilities of self-reliant type is an important research topic since the environmental aspects in water resources engineering have become urgent consideration. This paper deals with a selective intake from middle-high water flow in a small river, and a novel fan-shaped settling basin is proposed. Water is introduced to the settling basin from an intake weir and is withdrawn via a bell-shaped surface water intake. The hydraulic structure of this settling basin intends to prevent sedimentation in an attached reservoir when the water is taken from middle-high water flow. The soil particle distribution in the settling basin is calculated under a steady flow condition, where the water flow into the settling basin is highly turbid, and high performance of the surface water intake is demonstrated.
