An unlined channel in alluvial soil has a seepage loss of 2.5 cumecs/ million sq.m of wetted perimeter. The channel has a wetted perimeter of 25 m and has maintenance cost of Rs. 1 per sq.m of wetted perimeter. There is a huge scarcity of water in the area and as such the canal is to be lined with cement concrete lining 12 mm thick so as to reduce seepage loss to 0.02 cumecs/million sq.m of wetted perimeter. The lined channel will have a wetted perimeter of 20 m. The extra cost of lining works out to be Rs. 100/-per sq.m. If the average annual revenue per cumec of water is Rs. 25 lakhs and percentage reduction in annual maintenance cost is 40%, decide whether it is economically feasible to provide canal lining. Assume the life of canal lining as 50 years and the interest rate is 6 per cent per annum.

A trapezoidal irrigation canal has a bottom width of 2m and a flow depth of 0.9m. The sides have a ratio of 3 horizontal to 2 vertical. The channel bed has a slope of 0.001. If the Manning's Roughness Coefficient is 0.025, calculate the volumetric flowrate through the open channel. If the canal will serve a clay-loam rice land that demands 3L/s for every hectare, what is the total land area that can be supplied by the canal.
A trapezoidal channel is 5.0 km long with the side slopes of Z-0.5 constructed in clay soil. Up to the first 2 km, the bed-width of the channel is 4.90 m and the depth of flow is 1.05 m. Thereafter, the bed- width and the depth are 4.0 m and 0.885 m, respectively, right up to the downstream end of the channel. Estimate the total seepage loss through the channel by Moles-Worth
please correct answer only with two decimal places only A Trapezoidal canal is designed in alluvial soil using Lacey's theory to fulfill the irrigation needs. The cultural command area of the canal is 3000 hectares. The peak discharge required in Rabi season is 3 m³/s and peak discharge required in Kharif season is 5 m³/s. If the mean size of the sediment particles is 0.3 mm. Then the hydraulic radius that should be adopted for the channel is about

2. A rectangular channel section has a width of 2 meters and a depth of flow of 1.7 meters supports a flow of 10.2 m3/sec. The channel bed has a roughness correlating to a coefficient of 0.012. If excavation costs 650 pesos per cubic meter, compute the saving per kilometer of the canal if the most efficient trapezoidal section was instead used.
The specific gravity of the ground soil of an earth dam is Gs=2.58, the void ratio e=0.84, and the hydraulic gradient i e at the downstream seepage outlet is 0.22. If the safety factor Fs is 2.2, then ask whether there will be the damage of soil flow at the outlet of the earth dam?
The rectangular diversion channel is originally designed to have a width, B, of 12 m and depth, Y, of 2 m which is lined with concrete that has a roughness of 0.021. The distance from the city to the bay is around 8 km with a difference in elevation of 20 m. However, due to limited budget, it is proposed that the original design of the diversion channel be modified into most efficient rectangular hydraulic section. Knowing that the most efficient rectangular section is the one with a depth equal to half of its width or Y= 0.5B, determine the (a) new dimensions, Y and B of the modified rectangular channel and compute the total savings in (b) excavation cost, (c) land acquisition cost, and (d) concreting cost if the modified design is to be implemented but adhering to same discharge capacity. The unit cost of excavation is 400 per cubic meter, cost of the land is 1,500 per square meter, and concreting cost is 300 per square meter of lining.
