Abstract

The small dam holds back water running along a natural channel. It comprises a central modular element (1) which is easily transportable and is made of precast concrete. It has at least one discharge valve (20) on its upper part and a flush valve (21) on its lower part, together with the appropriate control apparatus. Abutments are also made of concrete, are transportable and can be easily adapted to fit the central element as well as the slopes on either side of the channel. Prestressing cables (8) hold the elements together and are anchored to the sides of the channel. These dams can be arranged in series in order to control the flow of water. They are cheap and simple to instal and have many advantages over conventional large dams.
