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.

4. A constant-head permeability test was conducted on a soil sample retained inside a cylindrical mould with a length of 40cm and an inner diameter of 18cm. In the test setup, a total of 55cm³ of water was collected during 3 hours and 15 minutes after reaching a constant-head difference of 60cm. a. Calculate the hydraulic conductivity (cm/s) of the soil sample. b. Estimate the type and permeability class of the soil. (Show all working calculations.)
Soil mechanics
A cylindrical soil sample with length = 15cm and diameter = 4cm was taken from a site where a groundwater contamination piume was found. The sample was tested in the lab to determine its hydraulic conductivity. A hydraulic gradient of 0.05 was applied across the sample, and a flow rate of 0.025 cm³/sec was measured. Calculate the hydraulic conductivity of the soil sample using Darcy's law.
