A canal is located in an area where its route parallels that of a nearby river. A stratum of coarse-grained soil 10 ft thick is sandwiched between a relatively impermeable fine-grained soil, and extends between the canal and the river. The distance between the river and the canal is ft, and the coefficient of permeability of the buried coarse stratum is 0. Make a sketch of the described conditions. Calculate the seepage loss from canal to river, gallons per day per mile of river canal length. What are flow nets and why are they used? Flow nets are a pictorial method of studying the path that moving water follows.

Make a sketch of the described conditions.
Calculate the seepage loss from canal to river, gallons per day per mile of river canal length. What are flow nets and why are they used?
Flow nets are a pictorial method of studying the path that moving water follows. They are used because it may be necessary to use flow nets to evaluate flow where the zones of flow or directions of flow are irregular, where water enters and escapes from permeable zone of soil by traveling a short distance, or where the flow boundaries are not well defined a boundary being the separation between where flow does and does not occur.
A concrete gravity dam is ft long from upstream to downstream end. It is constructed on a stratum of sand-silt soil 40 ft thick.
The coefficient of permeability for this soil is 0. Rock underlines the rock stratum. The bottom of the dam is 6 feet below the soil surface.
For the condition where the height of water against the upstream face of the dam is 45 ft above the soil surface, and the water level at the downstream end is just at the soil surface, draw the flow net for seepage beneath the dam and calculate the quantity of seepage in gallons per day per foot of width of dam.
For the condition where the height of water against the upstream face of the dam is 35 ft above the soil surface, and the water level at the downstream end is 5 ft above the soil surface, draw the flow net for seepage beneath the dam and compute the seepage in gallons per day per foot of width of dam.
The vertically upward flow of groundwater an artesian condition occurs through a sand deposit where the void ratio is 0. What hydraulic gradient is necessary for a quicksand condition to develop? The hydraulic gradient for an occurrence where there is a vertically upward flow of water through a sand mass is 0.
If the specific gravity of soil particles is 2. Well points are to be used to dewater a large trench excavation that extends a 35 ft below the surface of the water table.
Assume that the bottom width of the trench excavation of 70 ft.
