Abstract
A fish screen is presented having a porous surface made of two or more corrugations (e.g., elongated convex shapes) having an at least partially porous surface. The incorporation of a porous area on the corrugations allows increasing the total porous surface area compared to an underlying diversion area. The porous area is a magnification of an underlying diversion area, which reduces the fluid pressure (e.g., impingement forces) acting on the porous area of the screen. The valley between each pair of corrugations is solid, not porous. The solid valley(s) provide two important functions; they provide multiple small solid surface flow channels over the screen surface. These solid channels protect small or weak swimming aquatic organisms from impingement on the screen. That is, once organisms reach the solid channel, they may move along the solid channel free of impingement until they reach the edge of the screen.
