= 11.1 mlday The Figure below shows a cross section of a dam which can be idealized as an unconfined aquifer of hydraulic conductivity K. In order to prevent instability of the wall, the maximum Darcy's velocity (specific discharge) that should occur anywhere within the dam is specified as Vmax. Show that the minimum width W min needed to satisfy this requirement can be expressed as: 2 K W min = (ho? 20 maxho -hy?) he Ahw W 91
