“…They can achieve high rates of production handling a wide range of grain sizes, do not use a large volume of water or interfere with normal reservoir operation, and slurry pipeline is a clean and low-impact means to convey dredged material to the discharge point. A special type of hydraulic dredging developed for reservoirs is the siphon or hydrosuction dredge [75,76], which uses the difference in hydraulic head between the reservoir water surface and a discharge point near the base of the dam as the energy source for slurry transport. The hydraulic energy available is fixed by the reservoir level, which may vary.…”

Sedimentation is steadily depleting reservoir capacity worldwide, threatening the reliability of water supplies, flood control, hydropower energy and other benefits that form the basis of today’s water-intensive society. The strategies available to combat reservoir sedimentation may be classed into four broad categories. Three proactive categories seek to improve the sediment balance across reservoirs by: (a) reducing sediment yield from the watershed, (b) routing sediment-laden flows around or through the storage pool, and (c) removing deposited sediment following deposition. The fourth category (d) consists of strategies that adapt to capacity loss, without addressing the sediment balance. Successful management will typically combine multiple strategies. This paper presents a comprehensive classification of both proactive and adaptive strategies, consistent with current international practice. Functional descriptions and examples are given for each strategy, and criteria are provided to differentiate between them when there is potential for ambiguity. The classification categories can be used as a checklist of strategies to consider in evaluating sediment management alternatives for new designs as well as remedial work at existing sediment-challenged reservoirs. This will also help practitioners to more clearly describe and communicate the nature of their management activities. Widespread application of both active and adaptive strategies is required to bring sedimentation under control to sustain benefits of water storage for today’s and future generations.

“…The longest transport distances are achieved when uniformly fine materials are present as they can be transported at much lower velocities. Shelley (2019), building on an earlier analysis 7 , determined that a hydrosuction sediment removal system could remove a large portion of the accumulating sediment from the USACE's Tuttle Creek Lake in Kansas.…”

The US Army Corps of Engineers (USACE) maintains and operates 419 reservoirs nationwide for diverse purposes. This infrastructure is essential to the nation’s continued economic progress and provides numerous benefits. Sedimentation in reservoirs causes the loss of storage capacity, leading to interference with operations, reduction of project benefits, and eventual rendering of project operation technically infeasible or uneconomical. All reservoirs trap sediment, and sustainable long-term operation can be achieved only if sedimentation is managed. With many of the USACE reservoirs now reaching 50 years of age, sedimentation is starting to encroach on the beneficial pools. Under the paradigm of sustainable use, it is important to identify and implement strategies to sustain reservoir operation in the long term, beyond the period contemplated in the original project design life. This report outlines the major types of sediment management strategies available for reservoirs. Because the rate of new reservoir construction by USACE is very low, this report focuses on remedial strategies at existing reservoirs and presents a general methodology for the preliminary analysis of such sites. This report examines four example USACE reservoirs with known sedimentation issues to highlight the types of problems encountered and the development of strategies that can lead to sustainable use.

“…A 2016 reservoir dredging project at John Redmond Reservoir removed 3 M yd 3 at a cost of $20 M, or $6.67/yd 3 (KWO 2016). Promising and potentially less expensive dredging techniques such as hydrosuction (Shelley 2019) and water-injection dredging are currently being analyzed for effectiveness on reservoirs within the Kansas River Basin. However, due to unknowns, limitations, and current regulatory hurdles associated with these methods, this study used a sediment removal cost of $6.67/yd 3 to assess the monetary value of reducing sediment loads via streambank stabilization.…”

Accumulation of sediment has and continues to be a major problem facing reservoir managers and stakeholders. Sediment accumulation can be reduced by either preventing sediment from entering the reservoir or by removing it once it has been deposited, typically by dredging and upland disposal. Sediment transported into reservoirs generates from overland runoff and erosion of river beds and banks from upstream watersheds. This Regional Sediment Management Technical Note (RSM-TN) presents results of an analysis of bank stabilization as a means of regional sediment management within the US Army Corps of Engineers (USACE), Kansas City District (NWK), and distills lessons learned from previous bank stabilization project successes and failures. INTRODUCTION: USACE has a long history of streambank stabilization. Section 14 of the 1946 Flood Control Act, as amended, provides authority for USACE to plan and construct emergency streambank and shoreline protection projects to protect threatened highways, highway bridge approaches, and other nonprofit public facilities. These and similar projects have not historically counted the reduction in sediment loading to the river as a benefit during alternatives analysis. However, in many cases downstream projects including reservoirs, actively maintained navigation channels, and sensitive floodplain habitats can substantially benefit from the sediment reduction.
