Diversion Headworks
Scouring sluices are holes at the bottom of a or barrage that allow the sand to flow through them. Movable gates are used to cover these openings. When these gates are closed, silt builds up. When enough silt has built up, the gates are opened, and the silt flows through scouring sluices toward downstream. 4. Fish Ladder. Fig 5: Fish …

7 Different Types of Spillways
Spillways are classified into different types on the basis of the arrangement of the control structure, a conveyance channel and a terminal structure. In this article, we will discuss in brief all the different types of spillways with pictures. Types of Spillways. Different types of spillways are as follows: Straight Drop Spillway; Ogee Spillway
How to Make a Sluice Box
Many people design elaborate sluices that are way longer than necessary. Width is commonly about a foot or two wide, and the height is approximately 6 to 12 inches. Since a sluice should ideally be situated in a shallow section of stream, the depth of the box does not need to be much, just enough to capture water to flow over the riffles and ...
Design and Implementation of a Wire Rope Climbing Robot for Sluices
Regular maintenance of wire rope is considered the key to ensuring the safe operation of a sluice gate. Along these lines, in this work, a six-wheeled wire rope climbing robot was proposed, which can carry cleaning and maintenance tools for online cleaning and safety inspection of the sluice wire rope, without its disassembly. The developed …
