Hydrogeology of the Mahomet Aquifer System

Glasford aquifers

Mahomet Sand aquifer

North

slide11

Where:

is the vector of the observed hydraulic head

is the vector of parameters such as:

and

Pumpage (Q),

Leakage (L),

Recharge ( R),

Hydraulic conductivity (K),

Specific storage (Ss), and

Boundary conditions (BC)

slide18

Assumed recharge zones for the preliminary model. Zones 5, 6, 8, 9 and 10 are prior information zones.

slide19

Assumed hydraulic conductivity zones for the preliminary mode and the values of hydraulic conductivity [ft/day] from pumping tests.

slide27

Uncertainty analysis:

Assuming homoscedasticity (constant variance of errors) and uncorrelated errors among parameters, sensitivity analysis and Student’s t-test may be used to calculate the confidence intervals of the estimated parameters.

slide30

Groundwater Management Models:

1. A model for least cost pumping from an existing well field.

2. A model for capacity expansion of a well field.

3. A model for safe yield groundwater management.

4. A model for containment of pollution in a contaminated aquifer.

5. An economically based model for water resources planning for a multi-basin and multi-component system.
