• My objective of this project was to have
  experience in applying GIS technology in stream
  studies.
• This project was based on the MS research of
  Lance Christian from the department of Geological
  Sciences of University of Texas at Austin.

• In order to judge the degree of urbanization
  within a watershed.
• I choose The waller creek watershed in the
  downtown area for geochemistry analysis.
• I will use G.I.S to analysis the geochemical
  attribute by join data table of Alkalinity, major
  and trace element concentrations, oxygen, and
  strontium, PH, conductivity parameters.

• Work in progress!
• The following work should use the strontium-lead
  isotope system to create potentiometric surface
  map and link the geochemistry data with
  hydrological models.
