Visual materials, 1968-1996 and undated

This series consists of photographs, negatives, and slides created or collected by Nordin during his career. All chronicle research projects or professional conferences and meetings. Nordin used many of these images as documentation and data collection for research projects, so material in this series relates to project files in Series 1 and field books in Series 3. These items primarily relate to sediment measurement and bridge scour and are divided into two subseries by material type.
