屋面径流
从屋顶径流的降雨可以与降雨管控制和防浪墙储存进行模拟。可变深度公差值(TOL)可以被分配到容纳其他屋顶存储。根据屋面坡度,将屋面雨水径流加到建筑物周围的地表。一个正面的屋顶头,使水流被添加到地表水,而洪水仍会在建筑物周围。
Replicate Historical Rainfall Events with NEXRAD data
Model calibration can be performed with NEXRAD rainfall data. NEXRAD ASCII grid rainfall data can be interpolated to the grid elements using the GDS. A file RAINCELL.DAT is generated so that each grid element distinct rainfall data in the NEXRAD recorded intervals (typically 5 or 15 minutes). A historical rainfall event can then be simulated with spatially and temporally varied rainfall. Adjusted NEXRAD data to rain gages is necessary to compile rainfall data.
分流河道流量
坡面流可以代替单流程模拟小溪流和沟渠。越多的水流进入沟渠,小分流河道就越扩张。这种分流提高了冲积扇推进洪水的时间。
Channel Flow and Exchange of Channel and Floodplain Discharge
One-dimensional channel flow is simulated with rectangular, trapezoidal or surveyed cross sections. Unconfined floodplain flow is simulated in eight directions (4 compass directions and 4 diagonal directions). Overbank flow or return flow to the channel is simulated for each timestep. For detailed simulations the channel can be larger than the grid element. Tributary inflow is unlimited. The GDS can convert HECRAS cross sections into a data file formatted for FLO-2D.
