Hydraulic Design of the Pool-Type Fishway with V-Shaped Overfalls
Proceedings of the International Symposium on Fishways '90
Organizing Committee for International Symposium on Fishways
The objective of this paper is to present a pool-type fishway and its hydraulic characteristics. This fishway, with V-shaped overfalls, is applied throughout the Netherlands, especially in small steep rivers: sometimes in the river itself, in other cases as a by-pass of the main river. A review of the Dutch fishways is given, then the hydraulic design of the pool fishway with V-shaped overfalls based on hydraulic model investigations is presented. The paper concludes with design rules and recommendations for the improvement of the presented fishway.
