Concept explainers

Groundwater Flow

The term groundwater refers to the water which is found beneath the earth's surface. Pores present in the soil and rocks with fractures make a passage for rainwater to enter the earth's surface and deposit as groundwater. The flow nature and direction of groundwater under the earth's surface directly impacts the strength and compressibility of the soil, which reflects its ability to support structural loads.

Question

For a drinking and utility water facility, it is desired to pump water with a flow rate of 20 m³/hr from a well drilled in a pressurized aquifer with a thickness of 30 m. The hydraulic conductivity of this aquifer is estimated to be 0.0221 m/s. Level descents in two observation wells 120 m and 750 m away from this well were measured as 7.2 m and 1.7 m, respectively.
In order to be able to draw 20 m³/hour safely from this aquifer, the aquifer must be

A)Prove and interpret whether the hydraulic conductivity is correctly predicted

B)Calculate and interpret the transmission capacity of the aquifer according to the result we found for pulling 20 m³/hour

Someone pours a cup of water into an open well dug into a confined aquifer. If the piezometric head is 4m lower at the neighbors well 1500m away, how long will it take the poured water to travel to the neighbors well? Assume steady, unidirectional flow in a homogeneous silty sand confined aquifer with a hydraulic conductivity of 3.5 m day-1, and an effective porosity of 0.35.
A confined aquifer has a thickness of 85 ft. An 86-in diameter well drilled to the bottom of the aquifer, as shown in fig 3-10, if the hydraulic conductivity of the aquifer is 10 ft / day, and if water is originally 170 ft deep in the well, calculate approximately the maximum rate of flow that can be pumped from the well without dewatering any part of the aquifer. Assume 1000 ft reasonable value for the radius of influence. What will be the average velocity ( Darcy velocity ) of flow in the aquifer at a distance 20 ft from the center of the well?
A dam releases water into a spillway, and then some distance downstream a hydraulic jump occurs. The dam height is 25 m, the initial depth in the spillway is 1 m, and the hydraulic jump leads to a region of depth 15 m. Upstream of the dam may be considered a reservoir. Determine the average velocity before the jump and whether the jump will occur. If there will be a jump, determine the velocity after the hydraulic jump, neglecting any friction losses.
