"Teaching guide to Erosion and Sedimentation" by Pierre Julien, 1987

This series consists of reports, notes, and papers arranged in alphabetical order. Reports on groundwater research and water districts, as well as a binder of ditch information, are included. Reports by Robert Glover and a photocopy of testimony by Ralph Parshall are notable. Most materials from the 2011 accession were placed in this series and came primarily from Ayres Associates. Materials added in 2014 can be found in boxes 13 through 15 and include a number of items on Northglenn. Reports on the Cache la Poudre River added in 2019 are only available digitally.
