Revisiting the Concepts of Return Period and Risk for Nonstationary Hydrologic Extreme Events
Publisher: American Society of Civil Engineers
Abstract: Current practice using probabilistic methods applied for designing hydraulic structures generally assume that extreme events are stationary. However, many studies in the past decades have shown that hydrological records ...
Frequency of Recurrent Extremes under Nonstationarity
Publisher: American Society of Civil Engineers
Abstract: The concepts and methods for planning and design of hydraulic structures subject to hydrologic extreme events that arise from nonstationary conditions have emerged in the last few years. The traditional approaches such as ...
Quantifying the Uncertainty of Design Floods under Nonstationary Conditions
Publisher: American Society of Civil Engineers
Abstract: Estimating design quantiles for extreme floods in river basins under nonstationary conditions is an emerging field. Nonstationarities could arise from a variety of human and natural factors such as urbanization and climate ...
Probability Distribution and Risk of the First Occurrence of k Extreme Hydrologic Events
Publisher: American Society of Civil Engineers
Abstract: Statistical techniques have been developed for assessing structures to confront extreme events such as floods. Among them are probability distribution functions (PDFs). For example, the waiting time of the first flood ...
Chronic and Acute Coastal Flood Risks to Assets and Communities in Southeast Florida
Publisher: ASCE
Abstract: Chronic and acute coastal flood risks in Miami-Dade County are assessed over the range of sea-level rise (SLR) scenarios for the coming decades. The HAZUS-MH coastal flood hazard modeling and loss estimation tool are used ...
Multilayer Control Hierarchy for Water Management Decisions in Integrated Hydrologic Simulation Model
Publisher: American Society of Civil Engineers
Abstract: The regional simulation model (RSM) is a conjunctive groundwater surface-water hydrological model under development at the South Florida Water Management District. The model is designed to allow a flexible, extensible ...
Climate Links and Variability of Extreme Sea-Level Events at Key West, Pensacola, and Mayport, Florida
Publisher: American Society of Civil Engineers
Abstract: Analysis of long-term coastal tide records at Key West, Pensacola, and Mayport, Fla. examines the variability of extreme high-water events. Linear trends of event water level at Key West and Pensacola support findings ...
Sigmoidal Activation of Proportional Integral Control Applied to Water Management
Publisher: American Society of Civil Engineers
Abstract: A conventional proportional integral (PI) controller is modified with a nonlinear activation function (sigmoid function) applied directly to the controller output in order to improve the stability and target fidelity of ...
