Article Synopsis
- Sediment pulses significantly alter river and coastal landscapes, but measuring these changes has been challenging due to their unpredictable nature.
- The removal of two large dams on the Elwha River provided a unique opportunity to study the effects of a large sediment influx, with about 30 million tons of sediment released for observation.
- Over five years, nearly 65% of this sediment was eroded, influencing river channel morphology and contributing to the growth of the delta by approximately 60 hectares, with geomorphic changes peaking one to two years post-dam removal.
Restoration is frequently aimed at the recovery of target species, but also influences the larger food web in which these species participate. Effects of restoration on this broader network of organisms can influence target species both directly and indirectly via changes in energy flow through food webs. To help incorporate these complexities into river restoration planning, we constructed a model that links river food web dynamics to in-stream physical habitat and riparian vegetation conditions.
