摘要： 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.

摘要： A continuous flow measurement recorder is provided for making water flow measurements in an open channel. An ultrasonic sensor obtains pressure head measurements upstream from a flume or weir located in the open channel. A central processing unit receives the head measurements from the sensor and calculates the water flow rate and the total flow. A liquid crystal display device displays the water flow rate and the total water flow calculated by a central processing unit. A common, portable, easy to install housing is used to house and protect the sensor, central processing unit, and display device.

摘要翻译：呈现具有由具有至少部分多孔表面的两个或多个波纹（例如，细长凸形）制成的多孔表面的鱼筛。在波纹上引入多孔区域允许增加与底层转向区域相比的总多孔表面积。多孔区域是潜在转向区域的放大倍率，其降低了作用在筛网多孔区域上的流体压力（例如冲击力）。每对波纹之间的谷是固体，不是多孔的。坚实的山谷提供了两个重要的功能：它们在屏幕表面上提供多个小的固体表面流动通道。这些固体通道保护小游泳或弱游泳水生生物免受屏幕上的冲击。也就是说，一旦生物体到达固体通道，它们可以沿着固体通道移动而不受冲击，直到它们到达屏幕的边缘。

摘要： A baffle apparatus and method for directing fluid flow to reduce damage to an energy dissipating basin that includes an inlet, an outlet, a floor, a sidewall that extends upward from an edge of the floor, and an opposing sidewall that extends upward from an opposing edge of the floor defining a basin interior with a basin span between the sidewall and the opposing sidewall. The baffle apparatus includes a deflector structure that is generally planar and is fixedly or adjustably positioned substantially transverse to a downstream direction flow in the basin, the deflector structure spanning between the sidewall and the opposing sidewall above the floor. Also included, is a retaining structure for fixedly or adjustably positioning and securing the deflector structure to the sidewall. The deflector structure directs flow in the basin to flow in a downstream direction from a reverse upstream direction adjacent to the basin floor.
