Abstract
<p> Previous studies on the flow passing under the gates have exclusively directed towards discharge evaluation, and it seems that there is no study which gives direct information for gate operation. On the recognition that explicit expression of gate opening is most urgently needed information for gate operation, the present study aims to give the opening of sluice gates correspondent to the appointed discharge, water depth(s) of upstream and/or downstream of the gates for outflows on the basis of fundamental hydraulic equations. As for free outflow, expression of gate opening in terms of the discharge (critical depth) and upstream water depth was obtained from momentum theorem the experimental result on the relationship between discharge and upstream depth. As for submerged flow, a fourth order polynomial equation for gate opening with coefficients including the terms of discharge, upstream and downstream depths was obtained from the basic equations the same as those employed by Henry. The derived equations for gate opening showed good agreement with experimental data obtained in the laboratories.</p>
