Here is a puzzle that I've worked at for a while with out much result. Take profile station-elevation data, in this case stream profile data cut from a less than perfect LiDAR source, and filter the data such that only local minimum ordinances are left resulting in a station-elevation series...
Please share your thoughts:
What storm event would you use to determine the velocity, for use in calculating the time of concentration, through a constructed drainage ditch?
For a natural stream, I use bankfull discharge/velocity, which is typically the 1- to 2-year return period event. The...
Pseudo-static vs. pseudo-dynamic. Which one is the correct usage?
To me “pseudo” means not actually, but having the appearance of, i.e., pretending, mimicking. So a pseudo-static model would actually be a dynamic model that mimics a static system. Shouldn’t the appropriate term be a...
Is there a way to refer to a worksheet in the current workbook that is listed in a cell on a different sheet?
Say I want to retrieve the value of Cell A1 of Worksheet Sheet 2. From Sheet 1, I would write the equation =Sheet 2!A1. Except rather than typing "Sheet 2", I want to define it in a...
On what criteria does Excel (2007 particularly) decide when to use a zero minimum value with auto axis option, and when to use a non-zero value closer to the minimum value of the selected data?
At times I'll be happily working with a cart, changing data, etc. The chart axis min and max values...
Hi all,
I'm trying to get a feel for what methods engineers typically used to determine the stage-discharge rating curve of a grass-lined, open-channel spillway. Something you might see functioning as an emergency spillway at an earthfill dam or retention pond.
Please share what you...
Does anyone have any experience with river restoration and identification of bankfull discharge downstream of a dam? Or know of any reference or studies completed regarding the influence of a dam on bankfull discharge due to flow reduction and sediment starvation. I have a project of a 700...
