Hydrology 101 (For Those Who Skipped It in College) - 2017


At a loss when hydrologic engineers start throwing out fancy terms like flood return interval, antecedent moisture condition, initial abstraction, etc? As a professional working with these technical individuals and their reports, it’s essential that you fully understand where they are coming from.

Join two-time former IECA President, Dr. David T. Williams for the first part of our Surface Water Master Class series, a two-session live presentation exploring the concepts, terms, and analyses behind hydrology, and the basis of the analyses that goes into hydrologic studies. After covering the basics, we'll follow-up with an exploration of advanced topics (e.g., hydrologic losses, determining runoff, developing a hydrograph, and routing the channel downstream), as well as how this information is essential for good hydrologic design.

  • Hydrology 101, Part I
    In this session we’ll 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 design of flood control projects.
  • Hydrology 101, Part II
    In this session, we’ll move beyond the basics to advanced topics and how this information is used to develop information essential for hydraulic engineers to develop their designs. Advanced topics  include: hydrologic losses, determining runoff, developing a hydrograph, and routing the channel downstream.

Learning Objectives
Attendees can expect the discussion and education of the following learning objectives:

  • Learn the fundamentals of the hydrologic cycle.
  • Understand the meaning of hydrologic terms and how they are used in hydrology.
  • Understand how rainfall information is used to develop a flood hydrograph.
  • Understand how hydrologists determine the hypothetical frequency (such as the 100 year storm) of rainfall events.
  • Learn how rainfall information is transformed into a runoff.
  • Understand the procedures used to develop a hydrograph: its shape, volume, and peak discharge.
  • Learn how hydrographs are developed for areas that do not have rainfall information.
  • Understand the procedures used to determine how the hydrograph changes as the hydrologist tracks the flood downstream.
