Abstract : This Coastal and Hydraulics Engineering Technical Note (CHETN) summarizes the environmental benefits that could be gained by restoring sediment continuity from the Kansas River watershed to the Kansas River by passing sediment through, rather than trapping sediment in, large Federal reservoirs. The effort was conducted by the U.S. Army Engineer District, Kansas City (NWK), and supported by the U.S. Army Corps of Engineers (USACE) Regional Sediment Management (RSM) Program. The section of this CHETN titled In-Reservoir Effects of Sediment Accumulation explains the water quality and ecological effects of reservoir aging by sediment accumulation. The section titled Downstream Channel Effects cites specific ecological effects from unnaturally low turbidity levels in the Kansas River. The section titled Sediment Quality and Timing describes the natural quantity and timing of sediment delivery that can be used as a reasonable upper bound for all sediment recharge activities. Socioeconomic considerations, including impacts to water supply, flood risk management, recreation, and navigation support have been addressed by others and are not discussed here. This technical note documents multiple environmental benefits that could result from reservoir sediment management that removes sediment from major Federal reservoirs and recharges sediment to the Kansas River. The same may be true for other USACE reservoirs and their downstream receiving channels in historically turbid systems.
