Project Description

The primary goal of this proposed project is to determine the sources of fine sediment in highway and roadway runoff. A secondary goal is to distinguish relative contributions from traction sand, vehicle wear, tire wear, road surface wear, and vehicle emission particulates, as well as from adjacent land surfaces contributing to highways and roadways (for example, road shoulders and slope cuts) in highway and roadway runoff that reaches Lake Tahoe, either directly by stormwater runoff or by entering streams that flow into Lake Tahoe Another secondary goal is to develop a GIS representation for highways and roadways showing high, medium, and low areas of potential fine sediment yield for highway runoff.
