When the specific energy for a given discharge is plotted against the depth of the flow at

Question:

When the specific energy for a given discharge is plotted against the depth of the flow at a given section, a specific energy curve is obtained. The specific energy curve approaches the abscissa asymptotically for low depths (supercritical flow) and usually approaches a 45° line asymptotically for high depths (subcritical flow). Discuss the physical meaning of these limits.
