The W/R ratio is defined as the water storage capacity divided by the earthwork required to build such a reservoir/dam capable of this storage capacity. It is noted that, in some cases, a DG site with a higher elevation and hence a larger potential head may not be competitive with a lower site which has a larger W/R ratio.
