Abstract

The water-storage performance of an intake weir can be evaluated by stage-discharge ratings. The stage-discharge rating of a gabion weir depends on the physical characteristics of the filling materials. This study reviewed existing discharge formulae for the evaluation of the water-storage performance of gabion weirs. A previously published relationship between the characteristics of filling materials and experimental constants was adapted for stage-discharge rating. The mean size of the filling material is the most influential factor for the water intake and water-storage performance of gabion weirs.

취수보의 저류성능은 유량과 수심의 관계로 평가될 수 있다. 돌망태 취수보의 유량과 수심의 관계는 채움재의 물리적 특성에 따라 달라진다. 본 연구에서는 인공함양 원수확보를 위한 돌망태 취수보의 저류성능을 평가하는데 활용할 기존의 방류량 산출식들을 검토하였다. 채움재의 물리적 특성을 실험변수들과 관계식으로 표현한 기존의 방류량 산출식은 유량과 수심의 관계를 잘 표현하였다. 또한 채움재의 평균입경은 수심확보와 간접취수에 영향을 미치기 때문에 저류성능 뿐 아니라 취수성능에도 중요한 인자임을 알 수 있었다.
