Beginning at points a and b, sketch and label the water-surface profiles which are expected for gradually varied flow. P10.103 A circular painted-steel channel is running half full at 1 m3/s and is laid out on a slope of 5 m/km. Is this a mild or steep slope, of type 1, 2, or 3? Take R 50 cm. P10.104 The rectangular-channel flow in Fig. P10.104 expands to a cross section 50 percent wider. Beginning at points a and b, sketch and label the water-surface profiles which are expected for gradually varied flow.
