Evaluate the following statement, addressing what parts, if any, are right and which are wrong:
Jointing in rocks does not affect the flow of groundwater at depths greater than 10-20m because all fractures close below that depth.
Jointing is important, however, to engineers interested in stability of slopes and locating structures because joints can slide or open under gravitational forces on slopes.
The first statement is false, the second is true. Joints represent major pathways for groundwater flow but it depends on the fracture density vs permeability of the rock type.
