Bayesian modeling of effects of flooding and dam removal on epilithic algal biomass in a monsoonal Taiwan stream

Increasingly, dams are being removed to improve ecosystem integration. It is important to determine the effectiveness of these restoration efforts and the total cost of dam removal, especially in Mediterranean-climate and monsoonal streams with strong seasonal changes. In this study, we used Before-After-Control-Impact (BACI) design and a Bayesian mechanistic model to investigate algal responses to immediate and repeated sediment pulses after dam removal. Algal biomass decreased immediately after dam removal at a downstream site, and then rebounded within a month. Dam removal allowed sediments in the former reservoir to be washed downstream by high-flow events, but the pulses did not decrease algal biomass more than flooding alone due to scouring and burial. In monsoonal streams, the impacts of dam removal on epilithic algal biomass may be relatively temporary, and further study addressing the community structure is, however, needed to understand the further mechanism.
