This seminar is composed of two major topics: Hydrology and Fluvial Geomorphology.
At a loss when hydrologist or hydrologic engineers start throwing out certain terms such as flood return interval, antecedent moisture condition, initial abstraction, etc.? As a professional working with these technical individuals and their reports, it is crucial that you fully understand where they are coming from. We will discuss the hydrologic cycle, common terms, frequency analysis (how do you come up with the 100-year storm?), sources and use of precipitation data, and developing hypothetical (synthetic) storms for use in designing flood control projects. We will then delve into advanced topics and how the information gleaned therein is essential in order for hydraulic engineers to develop their designs. Such topics include hydrologic losses, determining runoff, developing a hydrograph, and routing the channel downstream.
Whether you are working on a water resources project, stream restoration, bank stabilization, or simply looking to brush up on your fluvial geomorphology basics…you are in luck! We are diving below the surface of fluvial geomorphology and into the depths to catch you up on the latest theories, approaches, and tools! We will start with examining the fundamentals of fluvial geomorphology and how it intersects with other disciplines, such as geology, ecology, engineering, etc. After covering the basics, we will delve deeper into watersheds, hillslope and stream hydrology, soil erosion and land degradation, river channel dynamics, sediment transport, flooding and flood management, floodplains, and deltas.
We will explore fluvial geomorphology and its relationship with watersheds, including the common terms and watershed elements, stability and instability definitions and conditions, and causes of river instability. We will also discuss watershed hydrological classification, channel profile and shape, and limitations of channel layouts for stream restoration projects. Then we will move beyond river behavior and into the computational tools you can use to determine design features for restoring streams based upon fluvial geomorphologic theories. You will learn how to identify various channel forms and their important features as well as discover the Rosgen stream classification system, guidelines, and best practices for use. We will also take a look at the inclusion of geomorphology in stream restoration projects, including channel forming discharge and equilibrium slopes.
Learning Objectives & Take-Aways
1. After attending this course, you will know the fundamentals portions of the hydrologic cycle and understand the meaning of key hydrologic terms and how they are used in science of hydrology.
2. You will be able to identify how rainfall information is used to develop a flood hydrograph and understand how hydrologists determine the hypothetical frequency (such as the 100-year storm) of rainfall events.
3. You will have better understand how rainfall information is transformed into a runoff and then used to develop a hydrograph: its shape, volume, and peak discharge.
4. You will discern how hydrographs are developed for areas that do not have rainfall information
5. You will gain familiarity with the procedures used to determine how the hydrograph changes as the hydrologist tracks the flood downstream.
6. You will understand key fluvial geomorphology concepts and terms.
7. You will understand the fundamental forces of nature that determine the forms of a river.
8. You will learn the relationships between river forms, streambank protection, and erosion control.
9. You will understand the significance of stream restoration as it relates to fluvial geomorphology.
10. You will dentify the functional components of a watershed and river
Professor David T. Williams, PhD, P.E, PH, CFM, CPESC; Fellow, ASCE, American Society of Civil Engineers.
Dr. David T. Williams, a registered Professional Civil Engineer in eight states, brings a variety of experience to Sem-Train, including: National Technical Director for Water Resources for PBS&J, co-founder and President of WEST Consultants (a nationally recognized water resources engineering firm), the U.S. Army Corps of Engineers, and adjunct professor at San Diego State University. Dr. Williams’ professional experience includes more than twenty years as a hydraulic engineer with the U.S. Army Corps of Engineers at the Waterways Experiment Station (WES) in Vicksburg, MS, both the Nashville and Baltimore Districts, and the Hydrologic Engineering Center (HEC) in Davis, CA. While at WES, Dr. Williams worked on research applications of sediment transport in rivers and reservoirs and the solution of unusual hydraulic and sediment related problems using computer models and other state-of-the-art techniques. During the mid-1970's, Dr. Williams worked at HEC, helping in the development of spatial data management techniques, evaluation of the economic benefits of flood control projects, and sedimentation in rivers and reservoirs.
Dr. Williams has been a frequent short course instructor for professional and public organizations on computer training using HEC-2, HEC-RAS, HEC-HMS and HEC-6. Dr. In addition, Dr. Williams has taught short courses on channel bed scour for toe protection design, sediment transport, stream restoration, fluvial geomorphology, pipe hydraulics and streambank protection, as well preparing for becoming an expert witness. Dr. Williams’ professional society activities have included past chair of the ASCE/EWRI Committees on Sedimentation, Computational Hydraulics, Risk, Uncertainty, and Probabilistic Approaches (RUPA) and Stream Restoration as well as 2-time past President of the International Erosion Control Association (IECA).
