Further information for topics mentioned in Monday’s class (9/21). These topics are beyond the scope of this class, but these are useful resources: Explanation of various types of borehole geophysics: http://ny.water.usgs.gov/projects/bgag/intro.text.html Use of surface geophysics in groundwater studies: http://pubs.usgs.gov/twri/twri2- d1/html/pdf.html Periodic table highlighting isotopes useful in hydrology: http://wwwrcamnl.wr.usgs.gov/isoig/period/index.html Reading for Sept 26 (Section 3.4 in Anderson and Woessner) How are transmissivity (or hydraulic conductivity) and storage coefficients determined? What is the “scale problem” with hydraulic conductivity measurements (and specific yield)? o If you are not familiar with scale effect in hydraulic conductivity, you can search

Unformatted text preview: online and read about it, or see these classic papers: http://info.ngwa.org/gwol/pdf/952564092.PDF https://info.ngwa.org/GWOL/pdf/992665841.PDF • How can heterogeneous layered systems be simplified and treated as a anisotropic homogenous layer? (Eqs 3.4a and b). Be prepared to calculate equivalent vertical and horizontal hydraulic conductivity. This is also discussed in most groundwater texts. • Please skim Eq 3.5, the section on kriging, and the boxes on PLASM and AQUIFEM-1. We will not discuss these in class • Carefully read Box 3.1 and be prepared to calculate intermodal transmissivities (or hydraulic conductivities) and the vertical leakage (VCONT) term....
