1. CE 394 K GIS in water resources
GEOCHEMISTRY of AUSTIN STREAMS
Qianru Zeng
Fall 2002

2. 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.

4. 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.

10. Nitrate concentrations
in public water supplies
have risen above acceptable
levels in many areas of the
world, largely as a result
of overuse of fertilizer and
contamination by human
and animal waste

15. Austin street and sampling locaton

16. 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.
