How do you determine the vertical hydraulic gradient at a site:

By installing two or more piezometers at the same site, with screens at different but known depths.

By obtaining detailed knowledge of the geological profile.

By pressure testing several closely spaced piezometers

By two or more piezometers spread far apart across the landscape.

Why is the hydraulic head (h) a useful quantity in groundwater studies (consider the density of water to be constant)?

Because it expresses water per mass.

Because without it, water will flow in all directions.

Because it allows us the determine the direction of groundwater flow between two or more points.

100%

Because water would flow uphill if we didn’t divide the total potential with the gravitational acceleration (g).

Define the transmissivity (T)

It replaces Kz and it is only valid if flow in the z-direction is zero.

It is the product of the hydraulic conductivity and the aquifer thickness.

100%

It is the product of the hydraulic conductivity in the z direction and the aquifer thickness.

It is the hydraulic conductivity in two dimensions (e.g., in the x-y plane).

Define the specific retention (Sr):

It is the porosity minus the specific storage (Ss).

It is defined as the volume of water that a unit volume of a confined aquifer releases for a unit decline in hydraulic head.

It is the proportion of the water contained at saturation that is held back in the soil by capillary and surface tension effects once the soil has drained.

100%

It is defined as the volume of water drained by desaturating the aquifer by a unit decline in hydraulic head.

If the flow from a catchment is 10m³/s for 3 hours and the total rainfall depth is 10.8 mm, what is the catchment area (in ha)?

Hint: remember one hectare = 10000m²

What is a piezometer?

An irrigation bore.

a bore with a short screen at the bottom which can be used to determine the hydraulic head.

a well from which to extract water.

a testing facility for pressure transducers.
