Sediment Removal Techniques for Reservoir Sustainability

Reclamation and its collaborators are launching a new prize competition seeking new or improved techniques for reservoir sediment removal and transport of the removed sediment in a cost-effective manner that preserves and sustains the operational objectives of the reservoir. Reservoir sedimentation has become a significant problem with the aging of water storage facilities. Sediment deposition in reservoirs limits the active life of reservoirs by reducing reservoir storage capacity for water supply or flood risk reduction. Sedimentation also impacts dam outlets, reservoir water intakes, water quality, recreation, upstream flood stage, and downstream habitat.

Greetings from the LooseNatural farm in Andalusia Spain where we currently live through a drought and we are creating swales

Ease up on the restrictions on hazardous materials in the sediment.

Place a huge number of buckets all along with width at the bottom of the reservoir at various intervals to collect the sediments.
Pull up the buckets when full. Empty them and place them back for the next round of collection.
By this method desilting can be done daily to maintain the water level.

[SaisamonChanthavong]

Where all those sediments will be borned?

[earlallnutt]

I have a solution. I have to prove my theory first, so be on the look-out for my research in the next few years.

[TPWWCAP]

What about using yellow line techniques??

[SMac]

One of hydro powers dirty little secrets, alongside methane output. But close your eyes, its green tech!

[MrWhylie]

I've seen it with my own eyes.
River channels are gone that were distinct, viewable structures.
In 40 years I've seen miles of top-end lakes silted.
Game fish can't nest and spawn in mud. carp and garr are OK.

What is the method name shown In 2.29sec

[roscocostco]

Sedimentation is the least of the problems we're passing on to future generations.

[bobrushton]

Ive read the challenge, and I do have a couple of good ideas, but you are only thinking of paying £11, 330 max so why would i consider helping you? its far too prescriptive an amount.

[olafelsberry]

I'm thinking you might be able to to mix it with compatible material

[robcarlmark]

What ever happened with this competition?

[partyYHard]

I have an idea, not tested but feasible I believe. a filtration channel at the mouth of the reservoir/dam. the water entering the reservoir will pass through this waterway in such a way the sediments will be distilled/separated from river basin leading to a water layer that contains more sediments and lower sediments. the sediment heavy water will be on the bottom layer and as it passes through the channel, a mechanism at the bottom of the channel will let the bottom layer sip through the channel bottom along a passage extracting it from the rest which flows into the reservoir.

[Trizsolvervn]

I has an idea!. Do you know anchor ice!
If I had a magic wand, I would command: "That mud(sediment) should rise to the surface of the water and go to shore." So our problem is solved.
And here is a scientific problem that needs research: Mud(sediment) only floats when it is lighter than water, with only air and ice. The mud
(sediment) is wrapped in ice, floats, flows to the gathering place, moves the ice onto the truck, waits for the ice to melt, we have dry mud on the truck, transported to the cropland.
We will save energy if we make it in winter!

[fosterkennel]

Yeah, well, now we're dealing with the Klamath River dam removal and millions of cubic yards of sediment full of toxic chemicals

[therainmaker]

Sediment removal, we manage to control it by using how a septic tank works.

[mikefoster]

Sedimentation in bodies of water other than the ocean are one main contibutor to rising sea levels

[pinshapemandle]

Your music is too loud and distracts from the presentation.

[TouchingClothProd]

Sounds like wishful thinking when it comes to Powell and Mead. 50K tons of silt per day is a lot of silt.
