Function and features line Time series change of rise and fall of flood water surface Xpswmm plug-in(free license version) required the user to set a movable model for the position of the flood waters. This caused a lot of work when there was a large water surface. The new plug-in automatically expresses the rise and fall of flood waters and reduces the time consuming process. Time series change of water flow vector The plug-in can show the time series expression of the flood water vector and direction. It allows the reproduction of the flow visually. Expression of conduits and time series change of water level inside conduits You can see the 3D VR expression of the drainage network. It can display the time series change of the rise and fall of the water level inside the conduits. xpswmm data import screen Using the screens below, you can adjust coordinates of the position to be displayed and import the "result of the flood" and the "result of conduit data" 1.Flood water surface drawing option 2.conduit drawing option Drainage network and flow in conduit UC-win/Road flood water surface UC-win/Road flood water surface vector link with "xpswmm"(xpx, xp file) Drawing of pipes and manholes, drawing of laid drainage and manhole, drawing of inside-pipe water flow information
