Question #$5(10$ Points$)$

The Darcy equation is used to relate the specific discharge $($or Darcy velocity; units of

length per time$)$ to the hydraulic gradient along a particular groundwater flow path.

a$.$ Write the equation and define all the terms.

$(3$ Points$)$

b$.$ For the one term of the equation $($parameter$)$ that is related to both soil and

fluid properties, name the soil properties and the fluid properties that affect it

and state how they affect it $($eg$,$ does an increase in the selected soil or fluid

property, increase or decrease the parameter?$)$

$(4$ Points$)$

c$.$ How do we estimate the actual groundwater flow velocity $($seepage velocity$),$

knowing the specific discharge?
