Reservoirs are bodies of stored fresh water that typically form behind dams. They are a critical water source, supplying farms with irrigation and providing potable water to people and homes. Increasingly, they are also an important component of outdoor, water-based recreation.
As rivers flow, they naturally carry along sediment (clay, silt, sand, and gravel). When rivers are dammed, sediments are deposited in the reservoirs that form behind dams. Sand and gravel deposit at the upstream end of reservoirs and form deltas that also extend upstream beyond the full reservoir pool. Clay and silt deposit farther downstream along the reservoir bottom and all the way to the dam. Over time, these sediment deposits build-up to the point where they significantly reduce a reservoir’s storage capacity and may prevent the proper function of dam outlets and reservoir water intakes. Without intervention, reservoirs eventually become filled with deposits, which means water is no longer being stored for future use.
The Bureau of Reclamation (Reclamation) is the nation’s largest wholesale water supplier. They operate over 330 reservoirs that store 140 million acre-feet of water. For reference, an acre-foot is 325, 851 gallons - which is enough to supply a family of four for one year.
Reclamation, in collaboration with the U.S. Army Corps of Engineers (USACE), is sponsoring this three-phase Guardians of the Reservoir Challenge. The goal of this challenge is to develop and demonstrate new processes and technologies that will collect and transport sediment from reservoirs at a rate that sustains their current capacity. Reclamation’s primary interest is in technology that will move sediment downstream at the average annual rate at which it would otherwise accumulate, but approaches that can help in regaining lost reservoir capacity are of interest if they can do so in addition to meeting environmental and other performance criteria.
The authors of the most compelling submissions to this Guardians of the Reservoir Challenge will have the opportunity to develop and demonstrate their technologies at increasing scales for the Challenge sponsors. In addition to prize money, winners may receive review comments and/or observations from their technology demonstrations and may have additional opportunities to work with Reclamation, USACE, or their partners to further develop their approaches.
Submissions must be received by October 20, 2020
As many as 5 of the top submissions will advance to Phase 2. Winners each receive $75,000 (total of $375,000 awarded)
Phase 1 winners have approximately 15 months to work according to their proposed project plans, develop their proposed approaches, perform a laboratory-scale demonstration, and submit a report
As many as 3 of the top-performing approaches will advance to Phase 3. Winners each receive $25,000 (total of $75,000 awarded)
Phase 2 winners have approximately 9 weeks to prepare for a large scale demonstration (scale, location, and other demonstration specifics to be mutually agreed upon), where they will set up and run their scaled-up demonstration for Reclamation, USACE, and their partners
A final event will occur at the end of Phase 3. Teams participating in Phase 3 will present an overview of their approach and results to Reclamation, USACE, and possibly affiliated commercial partners
Have you thought about forming a team to compete in the Guardians of the Reservoir Challenge? Teams can be formed directly on the challenge page by going to the team matching section, or by connecting in the forum.
Some of the advantages of forming a team include:
Those deadlines are less likely to get away from you when you’re working with a group.
2. Shared workload
You know the old “divide and conquer?” It works well for challenges too! By finding a solid collaborative stride, a group of even just three people can churn out a lot more than one person working alone.
It might be hard for other people to relate to your lone wolf journey toward incentive competition conquest, but your team will be right there with you! A source of inspiration, motivation, and perhaps even fire-under-your-butt lighting, teammates can provide a huge emotional advantage.
Maybe you’re a real visionary with an incredible concept but are stuck on how the “nuts and bolts” fit together. Yeah, YOU need a team. Teammates who have the skills and special working knowledge can be a huge resource. And the benefits go both ways!
Rome wasn’t built in a day. Your team will take some time to come together, so be sure to get ahead of it and start recruiting, reaching out, and networking about the challenge now. The team matching section is the best place to start to find individuals seeking teams and teams seeking individuals with specific expertise. If you don’t have any luck there, then try starting a new topic in the forum!
Maybe you've had some questions, thoughts, or ideas about the Guardians of the Reservoir Challenge, but you're still wondering where to put them. There's a quick, easy-to-use way to ask questions and start conversations: the challenge forum.
