TECHNICAL AND ECONOMICAL COMPARISONS OF RUBBER DAM WITH OTHER ALTERNATIVES

Rubber dam is a small dam which is used in rivers as a divesion dam. The only metal parts of these dams are the water proof anchor bolts. Sluice gates as well as hoisting devices are not necessary for their operation and the effect of foundation behavior on these structures is insignificant. Moreover, they do not influence the morphology of the river and require less expensive stilling basin. The cost of dam depends mainly on the width of dam and the labor fees for instalation. The average cost per length in meter is approximately 15000 US dollars at the present time. It is necessary to attain adequate knowledge to design and operate the control system of this structure.
