Sediment Removal From The San Gabriel Mountains, Mary C. Ferguson May 2012

Sediment Removal From The San Gabriel Mountains, Mary C. Ferguson

Pitzer Senior Theses

The issue of sediment removal from the San Gabriel Mountains has been a complex issue that has created problems with beach replenishment, habitat destruction and the need to spend millions of dollars at regular intervals to avoid safety hazards. Most recently 11 acres of riparian habitat, including 179 oaks and 70 sycamores, were removed for sediment placement. Other sites including Hahamongna Watershed Park and La Tuna Canyon also face a similar fate. This thesis questions: How did we get to this point of destroying habitat to dump sediment which is viewed as waste product? What are the barriers for creating …


Geomorphological Approach To Toxic Trace Metal Distribution Across A Medial Bar Deposit In The Trout Brook Of The Park River Watershed, Hartford, Ct, Kelsey Semrod Apr 2012

Geomorphological Approach To Toxic Trace Metal Distribution Across A Medial Bar Deposit In The Trout Brook Of The Park River Watershed, Hartford, Ct, Kelsey Semrod

Senior Theses and Projects

The Trout Brook, a major tributary of the Park River watershed, was sampled for heavy metals in sediment with a focus on Pb, Cu, Cd, and Zn. These metals are known to be contaminating the river due to a history of discharge from metal finishing industries. In a watershed-wide survey conducted in September 2011, high concentrations of metals were found in the Trout Brook, with some sites exceeding the probable effect concentration (PEC). The Trout Brook contains a Sanitary Sewer Overflow (SSO) and a vegetated medial bar that may be trapping sediment. Based on the results of the earlier studies, …
