But what about the Venturi Effect???

Hopefully I will refrain from typing oud two to three hours worth of lecture once given to Geology 101 students about the dynamics of stream flow. Here are basics concerning levees.
1) the stream economy formula (discharge = width X depth X velocity) always balances because it is a description, not a prediction or theory
2) when levees are constructed, you are trading less width for greater depth and velocity
3) consequently the stream rises higher behind a levee than it did before the levee was built, and this also increases velocity because the slope (or vertical drop) to all points downstream is increased
4) another way to think of it: levee construction creates a bottleneck causing water to backup on the upstream side (= at least temporarily the decrease in width caused by levee construction decreases the discharge flowing past the point where the levees are built, which causes impoundment of some of the discharge approaching the levees from upstream
5) this means upstream areas will suffer worse floods as a consequence of levees constructed downstream;
6) therefore upstream towns/communities will be obliged to construct levees, which will cause worse flooding upstream of them.

etc. etc. etc........

But what about the Venturi Effect???

Pressure is not a concern in stream dynamics. As I said, I don't want to type the entirety of several hours of lecturing. After all, there's also the gouging of the channel caused by increased velocity, and sedimentation upstream because of impoundment, and if a levee is breached, the levee then acts as a dam to prevent the water from getting back into main channel, and enrichment of "river bottom" land by sediment is reduced or eliminated on the "dry side" of levees (except when a levee is breached), and when discharge declines more sediment is dumped within the area bounded by the levees, including in the channel, which raises the entire level of the river in that zone, which increases the risk and potential severity of flooding in upstream, downstream, and levee proximal areas, and - - well - - it is not nice to fool with Mother Nature. or

Another quip I would tell students: building levees is like trying to put a stream into a pipe, except it's always only a half-pipe, open at the top down its entire length.

More produce pickers at the farm across the road. Not sure what they're picking, but the scent of celery fills the air . DAL 55-300 (@300) on K10D:

That hay field is long overdue but it made the morning dew shine like diamonds in that lighting!

Taken with a K-50 and DA*16-50.

That's a very pretty image. Really captures a moment worth saving.

Making bales the old ways. Of course the belt driven baler is a bit newer than the box method, at least I think it is. Wish I would have looked for a manufacturer tag, maybe I'll see it next year. And some folks think it's tough work now.
