The quizzes do test students on what was gained from the lesson but students won't gain/learn more if the answers are not given at the end for immediate review.

Self-paced slide format with interspersed review questions helps with retention of content and greatly helps with passing quiz.

Great for a wrap up for the flood lesion!

ward-forbesk 2018-09-17 02:28:31

An excellent explanation of the flash flood process.

This module is really helpful. I have learned a lot regarding on the processes of the flash flood.

Very interesting and useful

MaryAnnKaufman 2017-10-18 14:44:06

I would also have a GIS unit with this because it would be very useful for Raster Cover maps, which I'm sure is how some of this is displayed in the text. But it would drive home the point really well.

bjk,

kkinsland 2017-03-25 13:18:48

Solid module and provides enough basic information to a very good overview from a range of technical fields. Only criticism I would have is that the speaker goes very fast and makes it very hard to take notes without having to rewind, a lot! Tough to take notes and visual concept at such a rapid clip. But, I make it though none the worse and have a much better base of information.

Ssowell 2017-03-11 17:39:18

Ok

JonathanBelles 2014-05-12 01:46:30

Very well narrated!

God's Rebel 2014-01-17 10:25:39

This module is well done and narrated as well. It makes learning very easy and is very understandable. I recommend this module to any one wanting to learn more about flood prediction or meteorology.

pigfat 2013-02-20 14:52:14

The manner of presentation is well organized and the usage of graphics and animations are helpful. The audience for this module is wide, from meteorologists to hydrologists, so it is partly and necessarily simplified. The module goes into some detail about runoff curves, but I think there is a tendency for meteorologists to assume the runoff component is simply a reflection of infiltration excess. The process is more varied and nuanced than that, which can have important implications for operational procedures and forecasting prowess. It is good going in to the module to recognize this, and to explore further what specifically engenders flash flooding in your service area. I also think that although it is good to recognize the difference between basin, gridded, and County FFG, one should be cautious in using or applying gridded FFG. Ever-increasing computing power suggests this would be a nice addition to distributed modeling and forecasting (as hinted in the module). But I recommend putting some thought to this before moving forward from this module alone. As the contributors envision, seek out other sources of training and info on flash flooding. It is not a simple concept or forecasting endeavor.

Most of this module is very basic. It covers the same material found in other modules in this course. However, the "Flash Flood Guidance" section is worth going through. It offers some new information, and was/is widely used in many forecasts. The "Distributed Model", teased at the end of the module, sounds interesting as well, and provokes further research in the area.

Define a flash flood:

• Distinguish a flash flood from a general flood
• Identify the different physical processes leading to flash floods
• Recognize the connection between precipitation intensity and runoff characteristics associated with flash floods

Explain hydrologic influences on flash floods:

• Apply information about the runoff processes to the flash flood problem
• Explain why certain soil textures and soil profiles may result in greater flash flood risks
• Which physical characteristics make a basin more prone to flash flooding
• How quickly and frequently flash floods can occur in urban environments
• How fires and deforestation impact the flash flood risk

Understand key issues underlying the use of flash flood guidance (FFG) products:

• The definition of flash flood guidance
• How threshold runoff (ThreshR) and rainfall-runoff curves are used to derive flash flood guidance
• How flash flood guidance is generated for different spatial entities (headwater, county, gridded) and time durations
• Recognize when and how limitations can impact forecasts

July 2020 - The lesson was updated to current internet standards (mp4/html5), with no changes to content.

July 2014: Section 3 of this module focuses on the legacy Flash Flood Guidance (FFG) methodology used in the NOAA/NWS River Forecast Centers. Since the time of publication (2006) other methodologies for FFG generation have replaced the legacy product. These other methodologies (Gridded Flash Flood Guidance-GFFG, Flash Flood Potential Index-FFPI, Distributed model-based FFG) are not covered in the FFG section.
