Project 3 Hints

Landfill Site Landfill

Remedial Alternatives Alternative A - Do Nothing Alternative B - Impermeable Cap Alternative C - Cap and Confining Wall Alternative D - Cap, Slurry Wall and Drain Alternatives E, F and G Your Alternatives

Part A Create the working directory C:\temp\Proj3a Download the Vista1.gwv.zip file (from class webpage) Un-Zip the file to get the file Vista1.gwv Place the file in the working directory Open the model Vista1 Run the model (steady state)

Part a

Part B Create a new working directory C:\temp\Proj3b Keep a separate working directory for each part, so you can back up if you make a mistake Save (or copy) the file Vista1.gwv from C:\temp\Proj3a to C:\temp\Proj3b Select MODELS PATHS TO MODELS Set working directory to: C:\temp\Proj3b

Part b - Transient Model Setup In Part B: Convert the model to a transient model with 1 stress period

Stress period Types Select: Stress Period Types Set all to transient Set up the Stress periods Stress period length = 972,000,000 seconds (= 30.82 years) 20 time steps Time step multiplier of 1.5

Specific Yield Set specific yield = 0.28

Part b - Initial Heads Select: Model MODFLOW Package Options Initial Heads tab Select: Initial Head Location: Read Heads Directly from Binary Head Save File Browse Select: *.hds file from Part A MAKE SURE THE Part A HDS FILE IS IN A DIFFERENT FOLDER FROM THE PART B FILES!
