Abstract

Modeling Pathways of Phosphate Loading in the High Sierra Lakes
Track: 3D and Lidar Data
Authors: Micah Taylor

Nutrient loading is the process by which lakes become loaded with harmful nutrients. These nutrients cause algal growth, consumption of algae by microscopic organisms, which in turn consumes the oxygen supply in the water. This project used GIS analysis to find potential pathways of phosphates, one of the contributing nutrients, traveling from source to lake. Current 3D modeling techniques and CityEngine were used to visualize these pathways across complex terrain of the high Sierra Lakes.
