Tidal Power | Nature

ABSTRACT ESTIMATES of the power to be obtained from the rise and fall of the tide are often greatly in excess of practical possibilities. If it is assumed that an estuary or reservoir of

area A is enclosed by a dam at the outer face of which the difference of level between high and low water is H, then (_w_ being the weight of the unit cube of water) the work which might

conceivably be extracted from tidal action is _w_.AH2/2. To attain this end the relation between the water levels outside and inside the dam must be that shown in Fig. 1 by the full and

dotted lines respectively. The motors or turbines must be designed to work efficiently with any head from? to H, and able to do all the work in such a short time that the high and low water

levels remain practically constant during that interval, say 20 minutes. Access through your institution Buy or subscribe This is a preview of subscription content, access via your
