Abstract Flood frequency analysis generally involves the use of simple parametric probability distributions to smooth and extrapolate information provided by short flood records estimate extreme flow quantiles. Parametric can have difficulty simultaneously fitting both largest smallest floods. A danger is that observations in a record distort exceedance probabilities assigned large floods interest. The identification treatment such Potentially Influential Low Floods (PILFs) frees algorithm...
Uncertainties in instantaneous dam-break floods are difficult to assess with standard methods (e.g., Monte Carlo simulation) because of the lack historical observations and high computational costs numerical models. In this study, polynomial chaos expansion (PCE) was applied a flood model reflecting population large concrete dams Switzerland. The approximated metamodel uncertainty inputs propagated flow quantities downstream dam. study demonstrates that application metamodeling for...
Abstract. Estimates for rare to very floods are limited by the relatively short streamflow records available. Often, pragmatic conversion factors used quantify such events based on extrapolated observations, or simplifying assumptions made about extreme precipitation and resulting flood peaks. Continuous simulation (CS) is an alternative approach that better links estimation with physical processes avoids antecedent conditions. However, long-term CS has hardly been implemented estimate (i.e....
Analysis of geothermal energy resources in the Appalachian Basin eastern United States is interest, given region's population- and climate-driven demand for thermal energy. This study provides a fuller picture across New York Pennsylvania than previous studies by providing rigorous statistical analysis temperature-depth data using records from nearly 8000 locations. The compilation thousands enables significant increase spatial resolution resource assessment maps this region. In addition,...
The focus of this work is general methods for prioritization or screening project sites based on the favorability multiple spatial criteria. We present a threshold-based transformation each underlying factor into continuous scale with common interpretation across all compare several computing site and propagating uncertainty from data to metrics. Including allows decision makers determine if seeming differences among are significant. address using Taylor series approximations analytical...
Rare to very rare floods (associated return periods of 1'000–100'000 years) can cause extensive human and economic damage. Still, their estimation is limited by the comparatively short streamflow records available. Some limitations commonly used methods be avoided using continuous simulation (CS), which considers many simulated meteorological configurations a conceptual representation hydrological processes. CS also avoids assumptions about antecedent conditions spatial patterns.We...
