Abstract

Survey to support 2D hydraulic aquatic habitat models
Track: Water Resources
Authors: Randall Olden, David Anderson

In order to better understand the ecological implications of instream flow scenarios in the Gila River, the New Mexico Interstate Stream Commission completed topographic instream surveys of four study sites. The surveys incorporated data derived from multiple sources including LiDAR, RTK GPS, and terrestrial laser scanning. Data from each source were imported into ArcGIS and combined into a single terrain data set which was further processed for use in a hydraulic habitat model.
