1. Place the sluice parallel in a shallow area that has a good flow of water. You do not want whitewater flowing through the sluice, as you will more than likely lose material due to the fast flow of water. 2. Ensure that the bottom of the sluice is angled slightly lower than the gate of the box.

Keene got away from the side sluice design because the whole assembly has to be on top of their floats. More lift, less power. The undercurrent design let the whole thing sit in between the floats at water level, giving more suction for less power. The 6.5hp P180 will power a 5" subsurface dredge but is to weak for an above water sluice. It ...

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 ladder

The design of under sluices is critical to their function. They must be able to withstand the force of the water, as well as the erosion and corrosion that can occur over time. Engineers must take into consideration the type of soil and rock on which the dam or barrage is built, as well as the size and shape …

sluice in American English. (slus ) noun. 1. an artificial channel or passage for water, having a gate or valve at its head to regulate the flow, as in a canal or millstream. 2. the water held back by or passing through such a gate. 3. a gate or valve used in opening or closing a sluice; floodgate.

Sluice gates. 1. SLUICE GATE. 2. SLUICE GATE • A sluice is a water channel that is controlled at its head by a gate (from the dutch word "sluis" ). For example, millrace is a sluice that channels water towards a water mill. The terms "sluice gate", "knife gate", and "slide gate" are used interchangeably in thewater/wastewater control ...

General types of outlets are: conduit, tunnel, and sluice. These general types have various kinds of intakes and pro­ visions for gating and energy dissipation. Data Requirements The data requirements for outlets depend on site-specific conditions, project requirements, the level of design effort (preliminary or final), and special considerations.

Sluices at different heights mean that the tank does not allow equity in water supply to all the sluices. As a consequence, there may be mixed crop patterns due to differences in water availability. Water intensive crops are found in the area served by lower sluices while less water intensive crops are found in areas served by the upper level ...

3. Under sluices Also known as scouring sluices. The under sluices are the openings provided at the base of the or barrage. These openings are provided with adjustable gates. Normally, the gates are kept closed. The suspended silt goes on depositing in front of the canal head regulator.

Selection of foundation based on different types of soil. Foundations are recommended based on the different soil types which are provided below: Rocks. Uniform firm and stiff clay. Soft clay. Peat. 1. Rocks. This category involves rocks, hard sound chalk, sand and gravel, sand and gravel with little clay content, and dense silty sand.

The principal behind the sluice box is the same no matter what design is used. Water carries gold laden gravels down the box and gravity ultimately separates the gold from the lighter rock and sand. In theory, it sounds simple, in practice, there is a little more to it. Most sluice boxes use riffles or obstructions blocking free flow of gravel ...

2. Under Sluices. The under sluices are constructed on the side of the river where, the canal takes off through the structure known as the head regulator of the canal. If there are canals taking oft from both sides of the river upstream, then there shall be two under sluices, one on each sides. There shall similarly be two divide walls.
