This paper examines the spatial variability in the social vulnerability of residents to potential levee failures in the Sacramento Delta region. To determine the likely flood exposure, levees of concern to the U.S. Army Corps of Engineers and California’s Department of Water Resources were mapped. The HAZUS-MH loss estimation software and 100-year protection standard were used to hypothetically...

River floods frequently occur when tropical cyclones hit land. Nonetheless, systematic, long-term discharge data remain rather scarce in many countries, which prevent proper analysis of peak discharges occurring during floods. The Térraba catchment is the biggest and most dynamic Costa Rica. In this study, we developed regional flood-frequency analyses combining tree-ring based estimation measu...

Abstract Coastal communities around the world are experiencing increased flooding. Water level sensors provide real-time information on water levels and detections of flood risk. Previous sensor installations, however, have relied qualitative judgments or limited quantitative factors to decide locations. Here, we a method optimally place across community. We utilize multi-objective optimization...

The efficiency of regional frequency analysis (RFA) is undermined by intersite dependence, which is usually ignored in parameter estimation. We propose a spatial index flood model where marginal generalized extreme value distributions are joined by an extreme-value copula characterized by a max-stable process for the spatial dependence. The parameters are estimated with a pairwise likelihood co...

Flood damage modelling is an important component in flood risk management, and several studies have investigated the possible range of flood damage in the coming decades. Generally, flood damage assessments are still characterized by considerable uncertainties in stage-damage functions and methodological differences in estimating exposed asset values. The high variance that is commonly associat...
