Yield Model for Screening Surface- and Ground-Water Development
Publisher: American Society of Civil Engineers
Abstract: An optimization model is developed for selecting between candidate surface-water reservoirs and ground-water development. The model may be used to perform a preliminary screening of alternatives for water-supply development, ...
Atmospheric Flow Indices and Interannual Great Salt Lake Variability
Publisher: American Society of Civil Engineers
Abstract: This paper identifies connections between the time variability of the volume of the Great Salt Lake (GSL), Utah, and selected atmospheric circulation indices. The indices considered are the Southern Oscillation Index (SOI), ...
Nonhomogeneous Markov Model for Daily Precipitation
Publisher: American Society of Civil Engineers
Abstract: This paper presents a one-step nonhomogeneous Markov model for describing daily precipitation at a site. Daily transitions between wet and dry states are considered. The one-step, 2 × 2 transition-probability matrix is ...
Local Polynomial–Based Flood Frequency Estimator for Mixed Population
Publisher: American Society of Civil Engineers
Abstract: Floods are often generated by more than one physical mechanism, e.g., rainfall and snowmelt. Consequently, traditional flood frequency methods that use a single distribution may not adequately describe the observed flood ...
Stochastic Scenarios for 21st Century Rainfall Seasonality, Daily Frequency, and Intensity in South Florida
Publisher: ASCE
Abstract: We demonstrate that a nonhomogeneous hidden Markov model (NHMM) can be useful for simulating future daily rainfall at 19 stations in South Florida. Using upper atmosphere circulation variables that are typically better ...
Yield Model for Screening Multipurpose Reservoir Systems
Publisher: American Society of Civil Engineers
Abstract: A screening model for selecting and sizing potential reservoirs and hydroplants on a river basin is presented. The system is designed to meet annual irrigation and hydropower demands at prescribed levels of reliability. ...
Forecasting Spring Reservoir Inflows in Churchill Falls Basin in Québec, Canada
Publisher: American Society of Civil Engineers
Abstract: The performance of different models and procedures for forecasting aggregated May–July streamflow for the Churchill Falls basin on the Québec-Labrador peninsula is compared. The models compared have different lead times ...
Analysis of Climatic States and Atmospheric Circulation Patterns That Influence Québec Spring Streamflows
Publisher: American Society of Civil Engineers
Abstract: Results from diagnostic analyses to understand the seasonal evolution of the large-scale climatic state responsible for the development and melt of the winter snowpack, and spring–early summer precipitation in the Churchill ...
