GRASS's 6.4.1 Prediction of River Channels in Southern Staten Island
In the map below, I brought in the Hurricane Zone layer for zones A,B and C, where A is the zone in most danger of flooding. It appears that the river channel program was accurate in predicting Zone A. The GRASS 6.4.1 program does take into effect the elevations but the hydrology option sought of outlines where a river type of channel may be created and you can see this clearly on portion of the Staten Island Rapid Transit right of way and near Seguine Avenue.
