**Yabakei Dam**
**Definition**
Yabakei Dam is a concrete gravity dam located in Ōita Prefecture, Japan, primarily used for flood control, water supply, and hydroelectric power generation.
**Overview**
Constructed in the mid-20th century, Yabakei Dam plays a significant role in managing the water resources of the Yabakei region. The dam impounds the Yamakuni River, creating a reservoir that supports local agriculture and provides recreational opportunities. Its design as a gravity dam allows it to withstand the pressure of the stored water through its own weight.
**Structure and Specifications**
The dam stands approximately 70 meters high and stretches over 200 meters in length. It has a total reservoir capacity of several million cubic meters, enabling effective flood mitigation during heavy rainfall periods. The hydroelectric facilities installed at the dam contribute to the regional power supply, promoting sustainable energy use.
**Environmental and Social Impact**
Yabakei Dam has contributed to regional development by stabilizing water availability and reducing flood risks. However, like many large dams, it has also affected local ecosystems and required the relocation of some communities during its construction.
