Geology 127 (Hydrogeology)
California State University, Sacramento
Week 8: Specific discharge, average linear flow velocity, equations of flow (confined and unconfined aquifers), laminar and turbulent flow, steady state flow in confined and unconfined aquifers; refraction of flow, flow nets
Upon completion of this unit students should be able to:
Distinguish between specific discharge, average linear flow velocity, Darcy flux and Darcy velocity.
Discuss the assumptions and variables with each ground water velocity solution method.
Calculate the discharge per unit width for an aquifer.
Use equations for confined and unconfined aquifers to estimate hydraulic head at a known distance between two monitoring points.
Predict how groundwater will flow as it cross between media with different hydraulic conductivity
Read, interpret and construct a flow net
Make simple calculations using a flow net
