The purpose of the study is to simulate drown model on complete process operated by
diffusive tank model when low-lying region near seashore incur tidal bore poured into forcefully from
levee break rupture. Focus on the respect of the levee break, in order to analysis the influence of
drown region and drown depth in several conditions, the study design different width of the rupture
and is adapted to the revolution of automatic drainage floodgate. Because diffusive tank model is more
simplified from the model of unsteady non-uniform flow, we can get the result with good recurrence
by using lesser labor and computing time in the runoff analysis simulation. The analysis subject of the
study is a farm land consolidation region near seashore with the area of 845ha. The simulative result
shows maximum flow rate 7.4cms of automatic drainage floodgate with 9m height and 3m wide on the
width 2m of the rupture when storm come, Agricultural low lying region near seashore poured into sea
water from the levee break rupture, rising tidal bore 1.85m stage outside of levee. And maximum
submergible area inside basin is 19.159ha on the width 10m of the rupture at 56□ hour.
