Assessing the effects of reservoirs on extreme flows using nonstationary flood frequency models with the modified reservoir index as a covariate

Advances in Water Resources, 2019
The purpose of this study is to ascertain whether the changes in extreme hydrologic time series can be attributed to the reservoir operations by using nonstationary flood frequency analyses.

Flood susceptibility mapping by integrating frequency ratio and index of entropy with multilayer perceptron and classification and regression tree.

Journal of Environmental Management, 2021
Episodes of frequent flooding continue to increase, often causing serious damage and tools to identify areas affected by such disasters have become indispensable in today's society. Using the latest techniques can make very accurate flood predictions. In

Synthetic Flood Frequency

Journal of the Hydraulics Division, 1958
Procedure for computing flood discharge probability associated with given rainfall-duration-frequency pattern on natural drainage basins, non-channelized overland flow areas, and areas with storm sewer drainage utilizing basin runoff-producing characteristics of area; method utilizes time of concentration concept with unit hydrograph interpretation ...

Flood Frequency Analysis

2023
Hydrological processes are present in time and space in a manner that is partly predictable and partly random. We call them stochastic processes. In that case, the value of certain observations is not correlated with adjacent observations. This type of approach is appropriate for observations/measurements of extreme hydrological events such as floods ...

Nonstationarity-based evaluation of flood frequency and flood risk in the Huai River basin, China

Journal of Hydrology, 2018
Using monthly streamflow data from 9 gauging stations covering a period of 1960–2014 across the Huai River basin, China, the Pettitt method and GAMLSS model were used to quantify flood frequency and related implications for flood hazards.

Urban Flood Frequency Characteristics

Journal of the Hydraulics Division, 1974
This paper presents the results of a study concerning the occurrence and factors affecting floods from small urban watersheds. Based on Log-Pearson Type III flood frequency analysis on four urban watersheds located in Texas, urbanization has significantly increased peak discharge.

Coastal Flood Frequency Modeling

2016
Because of the complexity of flood forecasting, hydrological models and statistical models need to be developed for flood frequency analysis, and flood forecasting. In this chapter, the performance of LP3, GEV, PL and GP models was investigated for flood frequency analysis to find the most suitable flood frequency analysis method in the Oak Ridges ...
