I've been comparing the figures in TR-55 Fig. 3.1 and NEH-4 Fig. 15.2 (also in HEC 19 Fig. 52) for determining shallow concentrated flow. It looks like the TR-55 figure uses the same data as the NEH-4/HEC 19 figures but the TR-55 doesn't include all the ground cover conditions that NEH-4/HEC 19 does. Does anyone know why TR-55 limits the ground cover options to just "paved" and "unpaved"?
Thanks,
Ben
