Stream Aquifer Interaction (Lesson - Under Development) Beginner. This exercise explores the impact of stream stage fluctuations on adjacent aquifer systems (both unconfined and confined). Part I involves qualitatively describing the key parameters and relationships controlling groundwater response to stream fluctuations through the analysis of (vertical cross-section) profile models. Part II presents the mathematical framework of stream-aquifer interaction, giving students the opportunity to quantify groundwater dynamics and infer aquifer properties from observational data.
Groundwater Model Calibration Exercise - Fluxes and SWLs Planning to install a new 250 GPM well at their main facility, a small manufacturer hires you to determine whether their proposed well will cause any problems with the stream and an existing well and whether the new well or the existing well would likely become contaminated by a nearby TCE plume as a result of the operation of the new well. The new well will be operated continuously. The party responsible for the TCE plume has only recently been notified that they must remediate this plume. The State DEQ expects that it will be several years before this happens since it appears the State will have to go to court to force compliance. ​
Irrigation Drainage System (Intermediate - Analytical and numerical sub-problems.) The irrigation system for the Spartan valley is to control the water table at a minimum of 3.5 ft below the ground surface. This is done to prevent flooding in agricultural fields which can damage or completely destroy crops. The proposed solution is to create a system of 6ft. deep parallel ditches that `remove' groundwater through surface seepage, such that the water table does not rise to a depth less than the minimum allowable depth (see below).
