I need help on this problem Manning equation problem for parts a, especially rearranging the equation. Thank YOU They constructed 20-feet-high levees along the river channel. The channel constrained by the levees is 250 feet wide. For this exercise, assume that the channel cross-section can be approximated by a rectangle, with width, w, and the water depth, d. The Hydraulic radius is 17.24ft. assume that the channel slope is 0.0003 (a)Since late 1970s there was a push to restore river ecology and let vegetation grow back inthe channel. Assuming that vegetation in the channel will increase the Manning’s coefficient by 0.01,how much higher would the levees have to be to contain a flood with a maximum flow rate of 25,000cubic feet per second?

You are in charge of evaluating a segment of aqueduct pipe (diameter: 30cm). You know that pt. A has a measured pressured of 500 kPa. You must : a) Determine the head-loss between points A and B if they are separated by 100m, that the pipe has a flow of 175 1/s and that the Hazen-Williams coefficient is 100 (see figure 3) b) Calculate the absolute roughness (&). Presume that the water temperature is 15oC. A A Figure 3 Aqueduct pipe c) We wish to limit head-loss to 10 kPa, all the while transporting the same flow between points A and B. To do this, it has been suggested that a second pipe could connect these two points (see figure 4). You must determine this second pipe's diameter knowing that the total length of this secondary pipe is 135m and has the same Manning coefficient as the first pipe. Neglect all local head-loss B Figure 4 Proposed secondary pipe (dotted line) B
A channel has been designed to convey clear water to a fish hatchery. The design calls for aflow depth of 2.0 ft and a velocity of 2.0 ft/s. The channel is very wide so the side effects canbe neglected and the hydraulic radius taken as equal to the depth. It is to be constructed insand which has a median diameter ds = 0.915 mm (0.003 ft). For a flat bed in this materialthe Darcy-Weisbach friction factor is estimated to be f = 0.0185 and the required channelslope is S = 0.000145. The water temperature is 20°C and the kinematic viscosity υυ is = 1.08x 10-5 ft2/s. The specific gravity of the sand is 2.65. Clear water is admitted to the channeland it is imperative that no material be scoured from the bed since any sand in the hatcherywill result in instantaneous death of all the fish. Using Shields' diagram, determine if theexisting design is adequate to deliver clear water to the hatchery.
