re: Louisiana Scenic Rivers are Under Attack!

I live on a scenic river on the north shore. I can tell you that infront of my home it used to be 15 to 25 foot deep and the whole river was average 10 to 15 foot deep according to old timers. Now it's 8 feet deep infront and the average depth is so low everyone has to run jet foot boats to keep from eating up a prop. The reason.. Gravel pits.. I'm sure this is a lot of the reasons elsewhere why the rivers arnt what they used to be and yes along with man made structures. It all comes into play it's a multitude of problems.

Just a little basic hydraulics for you!!


Hydrology is probably the word you are looking for.

Nope. Hydrology is a much broader field. Like global water cycle/ water resources wide.

Hydraulics is concerned with the flow of fluids (in this case water) in pipes/channels. Rivers are a open channel situation with a free surface.

ScottieP does this for a living...

Yea but the problem is that many (a lot of big developers) are pushing for major dredging and even straightening of the rivers. In STT there are already deals being made to divvy up the dredge spoils so they can be used for fill credits.

In other words prepare for every inch of waterway to have a house on it.

I don' doubt you, but the only person that I have ever had the opportunity to question about the flow of water in streams called himself a hydrologist.

I think it's technically both in this case. The way water moves/acts as it flows in the open channel is hydraulic, but when describing/discussing how that water movement or changes to the channel affects surrounding systems (e.g. flooding, adding/removing impediments) is hydrology.

That's basically it.

Hydrologist- surface water

Hydrogeologist- groundwater

Hydraulic Engineer- mostly closed channel(pipe) and orifice flow, but there are many who study\model open channel flow.
