PURPOSE: A multifunctional ecological stream is provided to enable fishes and water plants to inhabit at all times by maintaining a regular water level in the stream and to prevent the lower part of an embankment from being lost by smoothly discharging deposits. CONSTITUTION: A multifunctional ecological stream comprises a fresh water stream water storage unit(11), a power generation beam unit, and an embankment support water storage unit. The fresh water stream water storage unit is separated by a cut off wall(100) included at regular intervals so that stairs are formed towards downstream. The cut off wall includes a water level interlocked floodgate opened according to a water level. A fresh water stream floodgate is artificially opened in a rainy season so that a fresh water stream floodgate opening unit is included to facilitate discharge. The power generation beam unit includes a fish way at 500-10000 m intervals. The power generation beam unit enables constant power generation and stores rainwater. The embankment support water storage unit is formed on the outer side of an embankment and supports water pressure by storing water in order to prevent the embankment from being washed away when the water level rises. |
