Daily Objectives #17 (March 17, 2009)                                        Dr. Sanders

By the end of today's class, you should be able to do the following: 

v Hydrogeologic Maps and Cross Sections

w Review: List the three major environments of deposition of glacial materials, describe the sedimentary deposits they leave, and tell whether each is most likely to be an aquifer or an aquitard.

w Explain these terms:         
     diamicton         outwash         till         buried valley                         
     lacustrine         moraine         varve    bedrock valley                    

v Ground Water Modeling: Conceptual Models
  Homework for Tuesday after break:

Write a one-page description of the geology of the study area.  (Refer to your cross section, and examine cross sections of other students in class today to get a more full, 3-D picture of the system.) 

Write a 2-3 paragraph description of the conceptual model.  At this point, it should include a description of the hydrostratigraphy and the boundaries to the flow system (we will add the other components next time).

Read the instructions for making a grid and constructing your own model.  Download and read these two documents:  First Steps and  Building Your Model   

v Ground Water Modeling: Practice

You may wish to examine the files below as a sample of a GGW model.  To get each file, double click on the link and select "Save File", then save each file in a place where you can find it again.  If that doesn't work, then just right click on the link on this page and select "Save Target As".  Remember where you save it to, so you can find it again!

(1) GGW Model for the Holiday Hills Community (file extension ".ggw")     

(2) Map Image for Holiday Hills (file extension ".bmp")

(3) Grid for this model (extension .xls) (you don't need this one to run the model, but you might want to look at it for your own information).
