Computes hydraulic dimension (cross sectional area, width, or depth) from a built-in table of regional hydraulic curve graph coordinates.
RHG_graph(region, drainageArea, dimensionType)The value of the requested hydraulic dimension
Used internally to convert historic studies that do not report regional relationships using the "power function" convention.
Other data:
RHG_graph_coefficients(),
region_min_max(),
regional_curve,
regional_curves()
# Calculate the cross sectional area for a watershed with drainage area = 1
# square mile in the Eastern United States region.
RHG_graph(region = "Eastern United States",
          drainageArea = 1,
          dimensionType = "area")
