✦ Synopsis

lkrodimmsional finite element analyses of two types of m i ) a conduit gate with pressure flow upstream of the gate and free surface flow downstream of the gate and (ii) a sluice gate with free surfacm both upstream and downstream of the gak-arc done using ideal h i d theory. The conduit gate problem is solved using both + and $-formulations. Various methods of satisfjmg the boundary conditions were tested for both formulations. The 9formulation developed in the pnscnt study is found to converge faster for flows with Froude numbers less than 4, which are common in sluice gates. The results obtained from the present study are compared with results from aualyticd and experimntal techniques available in the literaturr. The $-fornulation developed m the pnsmt study is then used to solve the spillway gate problem, for which no analytical solution is available.
