In this study several issues with the standard flood frequency analysis are discussed in the context of a changing hydro-climate in the 21st century. Among these issues the loss of statistical equilibrium in the hydro-climate of a studied region during the 21st century has serious implications on the standard frequency analysis that is discussed in some detail. An alternative method to flood frequency analysis within the framework of a changing climate based on ensemble of future climate projections is reported and demonstrated by a numerical application to a target watershed.

Interpretation of New Trends in Flood Frequency Analysis: A Case Study
Yanmaz, Ali Melih; Kentel Erdoğan, Elçin (null; 2008-05-27)
Conventional flood frequency analyses are based on use of a suitable univariate probability density function for maximum annual discharges. This approach is not robust enough since it deals only with the statistical distribution of annual series of peak discharges. However, flood events are better characterized by the peak discharge, volume of runoff, and the duration of the flood jointly. That is why there is a growing trend in the formulation of multivariate flood frequency analyses. A bivariate flood fre...
Assessment of changes in climate indices of the mediterranean climate region of Turkey
Çetinkaya , İzem; Yücel, İsmail; Department of Civil Engineering (2020-10-28)
As a consequence of climate change, frequency and intensity changes in extreme weather events have occurred. One of the most vulnerable regions of the world that is affected by the climate change is the Mediterranean region. Turkey as a Mediterranean country has a great importance to investigate the changes in climate behavior. 57 stations from Mediterranean climate region of Turkey have been selected as the study area for this thesis. This study aims to assess the climate indices that carry the valua...
Recent evidence of the relationship between carbon dioxide emissions, energy use, GDP, and population in Ghana: A linear regression approach
Asumadu-Sarkodie, Samuel; Owusu, Phebe Asantewaa (2017-01-01)
In this study, the relationship between carbon dioxide emissions, energy use, GDP, and population was examined in Ghana from 1971-2013 using a linear regression approach. Evidence from the study shows a long-run equilibrium relationship running from energy use (EU), gross domestic product (GDP), and population to carbon dioxide emissions. There was evidence of long-run equilibrium relationship from GDP to carbon dioxide emissions and population to carbon dioxide emissions. There was a unidirectional causali...
Multiresolution analysis of S&P500 time series
KILIC, Deniz Kenan; Uğur, Ömür (2018-01-01)
Time series analysis is an essential research area for those who are dealing with scientific and engineering problems. The main objective, in general, is to understand the underlying characteristics of selected time series by using the time as well as the frequency domain analysis. Then one can make a prediction for desired system to forecast ahead from the past observations. Time series modeling, frequency domain and some other descriptive statistical data analyses are the primary subjects of this study: i...
Computer assisted analysis of flow over spillway chutes
Kıranoğlu, Meriç; Yanmaz, A. Melih.; Department of Civil Engineering (2019)
In this study, a literature review is conducted in terms of assumptions, approaches, and various calculation methods used for the analysis of flow over conventional and stepped type spillways. In guidance of this review, a software is developed to perform such analyses with the set of given data by the user, and display results with some tables and figures. To this end, water surface profile over the spillway face is determined considering air entrainment process, pressure distribution over the crest under ...
