Hydraulic design of rubber dams (inflatable flexible
The hydraulic design of rubber dam is still embryonary because of the large number of intervening parameters and processes. In practice physical modelling is strongly recommended.

Hydraulic Rubber Dam | ScienceDirect
Inflatable weirs, also known as rubber dams, are flexible elliptical structures made of rubberized material attached to a rigid concrete base and inflated by air, water, or a combination of air and water. Those are made of durable fabric and are pressurized by air, water, or a combination of both. After rubber dam is inflated, it serves as weir.

Design and Analysis of Reinforced Rubber Membranes for
membrane of inflatable dams is too vague. Therefore, finite element analyses are needed to get the stresses of the multi-ply composite material with cover layers of rubber. Because of the rubber layers the inflatable dams are sometimes called rubber dams. In the end of the actual investigations, there should be a design concept for inflatable ...

HYDRAULICS OF RUBBER DAM OVERFLOW : A SIMPLE DESIGN APPROACH
Overflow of rubber dams is characterised by an accelerating nappe which adheres to the membrane wall. Hydrodynamic and fluid-structure instabilities may develop and must be avoided. Current design techniques include the installation of a fin an the upper quadrant of the rubber dam, to deflect the flow away from the flexible membrane wall.

Construction, operation, and maintenance of rubber dams
Abstract: Rubber dams are inflatable and deflatable hydraulic structures. Thousands of rubber dams have been in-stalled worldwide for various purposes: irrigation, water supply, power generation, tidal barrier, flood control, environ-mental improvement, and recreation. Furthermore, rubber dams have been used in cold areas where the temperature is

Inflatable rubber dam
Inflatable rubber dams are cylindrical rubber fabrics placed across channels, streams and weir or dam crests to raise the upstream water level when inflated. The membrane is a multi-layer fabric made of synthetic fibre (usually nylon) and rubberised on one or both sides. The fabric is quite flexible and yet exhibits good wear-resistance characteristics.

Rubber dam - Mécan Hydro
Rubber dam. It comprises of a flexible, high tensile, rubber-coated fabric bladder, which is permanently clamped to a reinforced concrete foundation. The bladder is inflated either by air or water, which in turn impounds and controls water flow, and is lowered by releasing the air or water from inside the bladder. Below is a brief introduction...
