Overland flow drainage on and from the tarmac of an airport invokes, in its design, principles involving :
(a) Spatially varied flow without hydraulic jumps
(b) Backwater flow
(c) Subcritical flow throughout
(d) Attention to rolling flows within spatially varied flows and possibly to moving hydraulic jumps
