A rectangular concrete channel (n = 0.015) has a bottom width of 10.0 m and a discharge rate of 43 m/s. Plot the specific energy diagram for depths ranging from 0.5 m to 3.1 m. From the diagram, determine (a) critical depth, (b) minimum specific energy, (c) specific energy for a water depth of 0.8 m, and (d) water depths when the specific energy is 2.7 m. What channel slope would result in critical flow?

I need the answer as soon as possible

Water flows in a horizontal, rectangular channel initially 10 feet wide and 2 feet deep. The initial velocity is 6 ft/s. This flow encounters downstream a simultaneous downward step and constriction. No energy losses are associated with these changes in channel configuration. a. What is the specific discharge, q: i. Upstream (for w= 10 feet)? ii. Downstream (for w = 6 feet)? b. What specific energy, E, is associated with the flow as initially specified (at the upstream location)? c. What is the minimum energy needed to pass the full discharge at the downstream location? d. What is the height (Az) of the smallest downward step necessary for the upstream flow conditions to remain as specified?

Question One Determine the flow rate in a confined aquifer with a hydraulic conductivity of 20m/d, and thickness of 6.6m. The initial piezometric surface is 14.53 above the lower confining bed, causing the piezometric surface to be 13.85m at a radius of 40m and a 14.31m at a radius of 85m. The solution should include a labeled diagram.
