E min
E min (c) Jeff R. Filler, Pell City, Alabama, 2022 But First, E apparent and E true `E min’ is calculated wood property used in the design of structural wood members (beams, columns, etc.). It is a derived property, derived …
Accuracy of Deflection Calcs (and Eee)
In the example above (link) we calculated a deflection of 0.599 in. How accurate is this number? (I showed it to three significant figures … accurate to half a percent?) Leaving out, for now, the accuracy/precision of the other input, …
E app (Apparent Modulus of Elasticity)
E app (`Eee app’, `Eee apparent’, Apparent Modulus of Elasticity) is a design property for wood construction. It comes from the Modulus of Elasticity of the wood (E, MOE, Young’s Modulus). It’s not a `true’, or `pure’ property, and it …
`Eeee’
E (Eeee!) (Steel for now; wood later) E stands for Modulus of Elasticity, or Elastic Modulus, also Young’s Modulus. It is also abbreviated MOE (`Em – Oh – Ee’). By definition it is the amount of stress (tensile or compression) …
Annual Exceedance Probability (AEP)
Annual Exceedance Probability … the probability a certain `annual-type’ event, e.g. annual river high flow/flood), etc., will occur (or be exceeded) in any particular year. See more … here.

The 100-Year Flood!
So, what is the probability that we will experience a 100-year flood next year? … in the `next 100 years’? Glad you asked. Next year? … 1/100 or 1% chance. Next 100 years? … see … here
what causes a stream to meander?
What Causes a Stream or River to `Meander’? (First) Hydraulic Equilibrium. Let’s think about a river that flows into the ocean. But the same could be said for a river entering a lake, or some other feature that `fixes’ the …
on sediment transport – Lane – I love it!
On Sediment Transport – Lane – `I love it!’ Lane (citation) gave us a fantastic, and fantastically simple, `equation’ (relationship) for sediment transport in a river. It goes something like this: river flow (quantity, Q) and stream slope (or steepness, …
