Geoelectrical Detection Of Water Table Depth At Two Locations In The Los Osos Groundwater Basin, Hallie A. Douglas
Geoelectrical Detection Of Water Table Depth At Two Locations In The Los Osos Groundwater Basin, Hallie A. Douglas
Natural Resources Management and Environmental Sciences
The city of Los Osos sits on top of a coastal groundwater aquifer which is the sole supplier of all its residential, agricultural, and industrial water needs. Lacking a sewer system, the upper aquifer became progressively contaminated with nitrates over several decades. Groundwater pumping eventually shifted to the lower aquifer, however seawater intrusion of the lower aquifer caused by over-pumping has further degraded water quality. The Los Osos groundwater basin provides an excellent field region to examine the utility of geophysical methods for characterizing aquifer structure. In this study shallow (<20 >m) electrical resistivity imaging methods were performed at two …
Road Cuts And Atterberg Limits Of Little Creek Road, Christopher A. Marquis
Road Cuts And Atterberg Limits Of Little Creek Road, Christopher A. Marquis
Natural Resources Management and Environmental Sciences
This senior project examined road cuts and soil adjacent to the road cut, along Little Creek road. Contrasting a landslide hillslope complex to a hillslope drainage complex, the project also compared the organic soil horizon to the mineral soil horizon in both soil units. The soils were analyzed using qualitative and quantitative measures of soil properties. The project utilized a road cut inventory to note the characteristics of the road cut such as presence of rill erosion, rock outcrop and sloping degree of the road cut. The project derived the plasticity index for both organic and mineral horizons, and compared …

An estimated 3.4 million people die each year from unsanitary water or inaccessible water supply. Most of these deaths take place in the developing, third world (99%). There is a dilemma arising on the world stage as well. The water demand/supply deficit is expected to increase significantly over the next 37 years if preemptive action isn’t taken. 97% of the world water supply is oceanic, making it an attractive solution to the water deficit. Providing autonomous, “deploy and watch” systems for utilizing sustainable energy to provide purified water for unitized low pricing has the potential to penetrate a large world …
