Adam R Mosbrucker

I specialize in the application of geomatics to study geologic and hydrologic hazards. My work utilizes remote sensing, geospatial modeling, field sampling, instrumentation, and surveying to quantify fluvial geomorphology and sediment transport in disturbed volcanic systems. I enjoy all things photographic in nature (e.g., photogrammetry, multispectral, and remote camera systems).
