ArcHydroを使用して流量を計算する

Question

<\/HEAD>ArcHydroを使用して排水区域の総流量を計算したいです。結果は毎秒立方フィートである必要があります。ArcHydroツールを確認し、FlowAccumulationまで進みましたが、毎秒立方フィートを得るために何をすればよいかわかりません。 <\/SPAN><\/P><\/BODY><\/HTML>

Arc Hydro will not calculate flow rates in cubic feet per second (cfs). Arc Hydro is used to help the parameters that go in to equations or models that are used to calculate the flow rate.

The tools in Arc Hydro are made to help automate the determination of the the parameters that come from watershed delineation process such as area parameter, flow path length and slope, watershed centroid, using the watershe polygons to convert raster based land values of impervious surface or infiltration rates to averages for the watersheds; thing like that.

Hope this helps,
