Generalized Method of Moments Applied to LP3 Distribution
Publisher: American Society of Civil Engineers
Abstract: The log‐Pearson type 3 (LP3) distribution is recommended in the United States by the Water Resources Council (WRC) as the parent distribution to maximum annual flood series. The parameter estimation technique proposed for ...
Sampling Techniques for Halphen Distributions
Publisher: American Society of Civil Engineers
Abstract: In this paper we present algorithms based on the acceptance-rejection (A-R), and Markov chain Monte Carlo methods to draw samples from Halphen distributions. Quantiles computed with these generating techniques are compared ...
Separation of Skewness: Reality of Regional Artifact?
Publisher: American Society of Civil Engineers
Abstract: Statistical distributions have often been used to estimate future flood probabilities based on a past record of flood events. To choose such distributions, one study in the United States considered a number of hydrologically ...
Closure to “<i>Separation of Skewness: Reality or Regional Artifact?</i>” by Fahim Ashkar, Bernard Bobée, and Jacques Bernier (March, 1992, Vol. 118, No. 3)

Multivariate Reservoir Inflow Forecasting Using Temporal Neural Networks
Publisher: American Society of Civil Engineers
Abstract: An experiment on predicting multivariate water resource time series, specifically the prediction of hydropower reservoir inflow using temporal neural networks, is presented. This paper focuses on dynamic neural networks ...
Frequency Analysis Incorporating a Decision Support System for Hydroclimatic Variables
Publisher: American Society of Civil Engineers
Abstract: Statistical criteria used to evaluate the best distribution fit give large weights to the center of distributions. This is, however, not consistent with the objective of frequency analysis which is to estimate the quantiles ...
Comparison of the Power of Lognormality Tests with Different Right-Tail Alternative Distributions
Publisher: American Society of Civil Engineers
Abstract: In flood frequency analysis (FFA), the adequate choice of distribution to fit data is a major problem. The three-parameter lognormal (LN3) distribution has an intermediate tail behavior between the distributions of the ...

New Plotting‐position Formula For Pearson Type‐III Distribution
Publisher: American Society of Civil Engineers
Abstract: The main objective of this paper is to develop a new unbiased plotting‐position formula for the Pearson type‐III (P3) distribution. The probabilityweighted moment (PWM) method is used to estimate the exact plotting positions. ...
Improving Daily Reservoir Inflow Forecasts with Model Combination
Publisher: American Society of Civil Engineers
Abstract: A major issue in real-time management of water resources is the need for accurate and reliable hydrologic forecasts at least 24 or
