ABSTRACT Erikson, L.H.; O'Neill, A.C., and Barnard, P.L., 2018. Estimating fluvial discharges coincident with 21st century coastal storms modeled with CoSMoS. In: Shim, J.-S.; Chun, I., and Lim, H.S.

Coconut Creek (Florida), ISSN 0749-0208. On the open coast, flooding is largely driven by tides, storm surge, waves, and in areas near coastal inlets, the magnitude and co-occurrence of high fluvial discharges. Statistical methods are typically used to estimate the individual probability of coastal storm and fluvial discharge occurrences for use in sophisticated flood hazard models. A challenge arises when considering possible future climate changes and the relation between the intensity of extreme coastal water levels and high fluvial discharges. In this study, the Coastal Storm Modeling System (CoSMoS) is used to dynamically downscale global clim...
