Dr. Chester Watson
Emeritus Professor
 Dr. Watson has practical experience as an engineer working in coal-fired steam generation electric power plants, as a utilities construction manager, in the design and survey for major river projects such as docks, pipeline crossings, mined land reclamation, and channel stabilization measures. He conducted approximately 25 floodplain information and flood insurance studies for the U.S. Army Corps of Engineers and FEMA. He was also in charge of numerous Hydrologic, Hydraulic, and Geomorphic studies for the Vicksburg, Mobile, Sacramento, and Memphis Districts of the U.S. Army Corps of Engineers. Dr. Watson has been a reviewer of mine reclamation plans for the Nuclear Regulatory Commission, specializing in hydraulic and geomorphologic related hazards. He also served as Principal Investigator for research projects involving erosional stability of watershed and stream systems, effectiveness of manufactured stream stabilization products, and river and stream restoration projects.
Technically, his emphasis has been on the analysis of watershed and channel system instability. He has given seminars to personnel of the Soil Conservation Service and Corps of Engineers incorporating geomorphic and hydraulic concepts. He has co-authored text books and has written chapters for other texts. Dr. Watson has conducted the geomorphology portions of the Waterways Experiment Station channel stabilization seminar, channel rehabilitation seminars for the U.S. EPA, and stream bank stabilization for IECA. He has been involved in a major research effort for Waterways Experiment Station, U.S. Army Corps of Engineers to develop methods for rehabilitation of streams that have been destabilized due to land-use change and channelization. This project, the Demonstration Erosion Control project, is a long-term, comprehensive effort to control erosion and channel degradation. Numerous full-channel grade control structure, side-channel drop pipes, riprap bank stabilization, and bioengineering projects have been constructed. Dr. Watson was in charge of a group that intensively monitors the performance of the constructed features and the response of the channel to the emplaced features. Working with Waterways Experiment Station personnel and other participating groups, Dr. Watson has developed design, monitoring, and evaluation tools for channel stabilization. He has also participated in the development and testing of procedures that will include physical habitat features as a component of the channel stabilization design. Other research includes development of guidelines for channel rehabilitation that will improve habitat value and maximize the natural reaeration capacity of the stream. Based on the natural reaeration capacity of the streams, Dr. Watson has conducted intensive physical model simulation of weir overfalls that could be used to improve the water quality of streams. Mathematical modeling has also been applied to assess the effect of using a stable channel morphology to improve a stream that was degraded by gravel dredging. Dr. Watson’s primary teaching emphasis at Colorado State University was in Environmental River Mechanics (CE413). Research activities have provided funding for numerous graduate students. Dr. Watson has been a member of the Larimer County Floodplain Review Board as a volunteer service to the community. Research Interests

Dr. Johannes Gessler
Emeritus Professor
Dr. Gessler retired in 2003 after having been associated with Colorado State University for 37 years. Over that period of time he served the Department and College in many different ways: as a faculty member, as Associate Department Head, as Interim Department Head, since 1990 as Associate Dean, and for a couple of years (1997-1999) as Interim Dean. So what after retirement? Since then he taught a couple of courses (Statics and Hydraulic Engineering) at times when the department was short handed. Perhaps more important, he continued to serve the College of Engineering as coordinator for students who are interested in the Study Abroad Program. He made presentations to freshmen students on opportunities related to Study Abroad, presented individuals with various alternatives, and helped them in the planning process. Engineering has become a very internationalized professional field. Many of our students will work on international projects, or work with civil engineers in other countries. Consequently, Gessler feels that the number of students to study abroad should be more like 20-25%. Shortly before his retirement Johannes was instrumental in creating an International Engineering option within the Engineering Science major. Students in this option concentrate their engineering studies in one of the traditional engineering fields, and supplement this curriculum with various courses in International Studies.

Overland Flow
Research on overland flow has started in Canada as my part of my own thesis and dissertation topics. More recent research on overland flow has been funded by ARO and ARL since 1986. Some of the papers below refer to the overland flow characteristics from raindrop impact to sheet flows, roll waves and the applicability of simplified equations of motion.
Surface runoff modeling
Surface runoff modeling has been the emphasis of our activities within the Center for Geosciences. This on-going project has been funded by ARO and ARL since 1986. We have developed numerical algorithms for the simulation of rainfall-runoff using GIS terrain data, raingages and/or radar rainfall precipitation. The model CASC2D has been developed at CSU by Dr. Julien in collaboration with numerous students including Drs. Bahram Saghafian, Fred Ogden, Bill Doe, Darcy Molnar, Amit Sharma, Billy Johnson, and Jeff Jorgeson, who completed their Ph.D. studies at CSU. The most recent version of the model is CASC2D-SED which simulates soil erosion from overland flow and routes sediment by size fractions to the outlet of a watershed. Rosalia Rojas is pursuing new developments with the model CASC2D-SED is under further development to determine the effect of grid size in the calculations of soil erosion.
Upland Erosion
Research on upland erosion has started in Canada as my part of my own thesis and dissertation topics. More recent research on overland flow has been funded by ARO and ARL since 1986. Some of the papers below refer to the modeling with CASC2D-SED and the transfroms for the analysis of flow and sediment duration curves. The most recent version of the model is CASC2D-SED which simulates soil erosion from overland flow and routes sediment by size fractions to the outlet of a watershed. Rosalia Rojas is pursuing new developments with the model CASC2D-SED is under further development to determine the effect of grid size in the calculations of soil erosion.
Alluvial Channels
This on-going project started during the author’s post-doctoral studies and has been recently funded by the USBR since 1996. We have developed a method for the determination of the downstream hydraulic geometry of alluvial channels. The research has been carried out in collaboration with J. Wargadalam, Claudia Leon, Travis Bauer and Gigi Richard, who received graduate degrees at CSU.
Resistance to Flow and Bedforms
The analysis of resistance to flow and bedforms has been the subject of research in collaboration with Delft Hydraulics and the USBR. The analysis of bedform geometry and resistance to flow has been the author’s research topic during his two sabbaticals in 1991 and 2000. Research on the Rhine River has been in collaboration with Gerrit Klaassen at Delft Hydraulics. Additional research at CSU has been carried out by Y. Raslan during the course of his Ph.D degree at CSU.
Local Scour
Research on local scour has been intermittent with interest from USDA for the analysis of rill erosion and interest from FHWA for the analysis of pier scour and scour below drop structures. The investigations have been performed in collaboration with N.l Bormann, O. Stein, and C. Santoro, who received degrees from CSU.
Sediment Transport
This analysis of sediment transport in rivers has been a primary research area since 1977. First studies relate to sediment transport in canadian rivers in collaboration with marcel Frenette. Recent investigations refer to the mechanics of sediment transport. The research results available here refer to the studies in collaboration with Hyoseop Woo, Junke Guo, and Otto Stein who received graduate degrees from CSU. This web site contains numerous papers and technical notes on published results. The analysis of hyperconcentration, mudflows and debris flows is available in a separate item below.
Mudflows and Debris Flows
Research on hyperconcentrations, mudflows and debris flows in mountain streams has been on-going since 1983. Research has been carried out in collaboration with J. O’Brien, H. Woo, Y. Lan and J. Guo who not only manifested great interest in the topic, but also earned Ph.D. degrees at CSU.
