Flood Frequency: Calculating 100-Year Floods

Everyone knows that a 100-year flood is a really big flood. But not all big floods are 100-year floods, and a 100-year flood is not necessarily the same as a 100-year storm. So…how can you ensure your floodplain structures are designed to handle any flood nature may have in store?

Join returning speaker Doug Beyerlein, P.E., P.H., D.WRE, in our online training webinar as we examine the different flood frequency methods available to an engineer, the key assumptions contained in each method, and how to select the appropriate flood frequency method for the engineering job at hand. We’ll also discuss situations where flood frequency is not the appropriate design parameter and what flow-related method should be used instead.

Specifically, we’ll discuss how engineers use flood frequency as a design standard in sizing many, if not most, structures within a floodplain—ranging from designing culverts and bridges, to determining roadway and building elevations, to sizing flood control structures. Calculating a flood frequency value is not difficult, but selecting the appropriate flood frequency method to calculate the frequency flow value can be.

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

  • Understand why flood frequency is not the same as storm frequency.
  • Explore the different methods for calculating flood frequency.
  • Analyze the key assumptions built into each flood frequency method.
  • Learn the regional hydrologic characteristics that are important in flood frequency method selection.
  • Determine when flood frequency is not the appropriate design parameter.

Water Well Journal – July 2017

We have just received our digital copy of the Water Well Journal for July 2017.  This issue discusses topics such as well rehabilitation and chemicals, well efficiency and fluid mechanics, water quality, engineering water systems, conversing with customers, benefits of ongoing training, pump rehabilitation and safety matters in relation to types of safety gloves used.

Water Well Journal – April 2017

We have just received our subscription of the Water Well Journal for April 2017 from the National Groundwater Association (NGWA).

Water Well Journal April 2017
Water Well Journal Volume 71 Issue 4 (April 2017)

This issue includes articles on well design, wells’ life-cycle, nitrates and groundwater, water treatment, preventing muscle injuries through ergonomic processes, managing cash flow, engineering of water systems and other relevant information.

Those of you who are interested in viewing this journal can email me or visit me at my desk.


Water Well Journal – February 2017

Although our section does not focus so much on groundwater activities, as much in the past, with Wells Meeting and the like, I do look forward to our Water Well Journal subscription since it helps keep us abreast of technology trends that are occurring in the drilling world, as well as, provides articles that can be applied to performance and safety measures and overall best practices in the office.

The journal subscription for February, 2017 is no different, since it documents, aerial drones to monitor drilling on site, guidelines for posting work related information online, engineering for water system designers and a review of commonly used performance indicators.

Water Well Journals 2016

Digital copies of the Water Well Journal by the National Ground Water have been received for the months of April, May, June, July and August for the year of 2016. Persons wishing  to view any of these journals may visit me at my desk or send me an email.

Although I wanted to download these before posting, due to some network connection errors I have only been able to download the journal for the month of April.

However, since  the information can still be accessed via the link persons would still be able to read up on new developments in the world of drilling, as well as, view discussions on topics such as geothermal systems, safety in the workplace, aquifers and other relevant topics.


Water Quality Engineering: Physical / Chemical Treatment Processes

Water Quality Engineering Physical/Chemical Treatment Process Mark M. Benjamin and Desmond F. Lawler

I recently came across one of the bestselling textbooks offered by Wiley. As a text which is described as offering explanations for “both the underlying theory and the underlying mathematics, this text enables readers to fully grasp the fundamentals of physical and chemical treatment processes for water and wastewater.” (Wiley, 2016)

It is also recommended for professional environmental engineers in search of a contemporary perspective on water and wastewater treatment processes so I believe that it would be a good fit for the Agency for a new text for the library. Also, due to its ability to provide problem sets and examples for students to figure out the mathematics behind the physical and chemical treatment processes for water and wastewater, it would greatly be welcomed by our interns in the relevant field of water quality engineering.

Persons can read the full description offered Water Quality Engineering: Physical / Chemical Treatment Processes.

Water Well Journal January 2016

We have just received the digital edition of the Water Well Journal for January 2016 (Volume 70 Issue 1) from the National Ground Water Association.

In this issue pertinent topics are discussed such as well rehabilitation, well health, engineering of water systems, workplace drug and alcohol testing, planning and efficiency and safety.

Those wishing to view this journal can contact me via email or phone or visit me at my desk. 🙂
