Surface Water Hydrology: Parts I and Part II

Part I - Available as Download
Part II - Wednesday, August 7, 2019 | 1:00pm ET

At a loss when hydrologic engineers and hydrologists start throwing out certain industry 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.  Join Dr. David T. Williams for this live, educational, webinar exploring the concepts, terms, and analyses behind hydrology and the basis of hydrologic studies.

Surface Water Hydrology 101, Part I - Available as Download
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.

Surface Water Hydrology 101, Part II - Available LIVE on Wednesday, August 7, 2019 | 1pm ET
Moving beyond the basics, we will 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.

Learning Objectives:
Part I:

  • Learn the fundamentals of the hydrologic cycle.
  • Understand the meaning of hydrologic terms and how they are used in hydrology.
  • Identify how rainfall information is used to develop a flood hydrograph.
  • Discover how hydrologists determine the hypothetical frequency (such as the 100-year storm) of rainfall events.

Part II:

  • Examine how rainfall information is transformed into a runoff.
  • Explore the procedures used to develop a hydrograph: its shape, volume, and peak discharge.
  • Discern how hydrographs are developed for areas that do not have rainfall information.
  • Comprehend the procedures used to determine how the hydrograph changes as the hydrologist tracks the flood downstream.

Presenter: Dr. David T. Williams

Dr. David T. Williams, a registered Professional Civil Engineer in eight states, with a variety of experience including: National Technical Director for Water Resources for PBS&J (now Atkins), 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.

Session Details: PART II - Wednesday, August 7, 2019 | 1:00pm ET (90 minutes). Plan to login 10 – 15 minutes prior to the start time of the webinar.
