For the trapping water in reservoir to install water gate as of various type, we have studied results as of flow pattern without vortex and bubble at turbine inlet in the small hydraulic power-plant. In case of overflow conditions on the top crest of water gate, overflowing effect with test matrix is reviewed by phenomenon of surface wave using the flow test and numerical simulation. We ascertained that height of wave is lowed and vortex/bubble at turbine inlet is reduced as overflowing is larger.
