Short Biography

Adam Mosbrucker is a staff memeber at the Cascades Volcano Observatory in Vancouver, Washington. His work at CVO is highly multidisciplinary and dynamic. Mosbrucker’s role in the hydrologic monitoring project includes field data collection, processing, analysis, and interpretation. He provides support to a wide variety of volcano hazard monitoring and research projects. Mosbrucker's own research is focused on direct and remote sensing methods of applied and quantitative fluvial geomorphology and sediment transport in disturbed systems.

Hydrologic Monitoring

Hydrologic monitoring at CVO includes water and suspended-sediment discharge, turbidity, lake elevation, and lahar/debris flow detection. Our work focuses on the long-term impact of excess sediment. As a hydrologic monitoring project staff member, I support field data collection, instrumentation, stage-discharge rating development, data QA/QC, and record publication efforts. I also conduct research using remote sensing technology to advance the science of sediment monitoring through partnerships with other agencies.

GIS & Geomatics

My primary interest is in direct and remote sensing methods of investigating fluvial geomorphologic change and sediment transport in high-gradient streams and disturbed landscapes. Geomatics is a fundamental component to my work at CVO. Geomatics is the integrated approach to geospatial data acquisition, processessing, analysis, management, and representation – including Geographic Information Systems (GIS), Light Detection And Ranging (LiDAR), Structure-from-Motion (SfM) close-range oblique photogrammetry, geodesy, Global Navigation Satellite System (GNSS/GPS), and traditional land surveying.
