Abstract Estimation of large to extreme floods in the range of  years return periods to probable maximum floods (PMF) is needed in planning and designing of large water resources management by: 1. The Flood Studies Report provided a choice of means (Fig. ) of estimating the flood hydrograph of any return period, or the estimated maximum flood, from an estimate of the storm depth and its time profile and its conversion to river flow.

Government Printing Office. The term “design flood” is used to denote the maximum flood flow that could be passed without damage or serious threat to the stability of engineering structures. It is therefore, necessary to specify volume and period of flood flow that may flow down in conjunction with the peak flow.

This chapter discusses the parameter estimation of the series of maximum flood flows. The problems of processing culminating flood flows were given considerable importance as early as at the time when probability theory had just begun to develop and when the methods of the theory of estimation had not yet been satisfactorily elaborated.

Flood estimation has a core rôle in understanding the flood regime and quantification of flood risks in a river catchment. Flood estimation is a specialist branch of hydrological.

In many regions, annual floods follow the thaws and rains of spring; flooding also may occur because of thawing ice jamming narrower and shallower parts of a river. In the Arctic regions, especially in the basins of northward flowing rivers, the floods are caused by the thawing of the southern portion of the basin before the ice blocking the.

The extreme value distribution was an introduction by Gumbel () and is commonly known as Gumbel’s distribution.

it is one of the most widely used probability distribution functions for extreme values in hydrologic and meteorologic studies for prediction of flood peaks, maximum rainfall, maximum wind speed.

Flood loss estimation. Flood damage estimation was undertaken for all the three categories; urban, rural and infrastructure. However, verification of the results with actual surveyed data could be done only for urban damage due to non-availability of surveyed data for other two by: Additional Physical Format: Online version: World Meteorological Organization.

Designs of most major dams and spillways are based on probable maximum floods (PMF). When properly estimated, PMFs provide the basis for confident sizing of spillway. There are, however, many factors which affect the estimation of a PMF.

In analyzing each of these factors, certain assumptions have to be made and subjective judgements : Bi-Huei Wang.He will offer suggestions for development of an up-to-date method for reservoir flood estimation that builds on existing methods and considers the effects of climate change on extreme floods.

He will also give some hints and tips for practitioners carrying out reservoir flood studies in the meantime.Accurate estimation of flood frequency not only helps engineers in designing safe structures but also in protection against economic losses due to maintenance of structures.

In order to understand how flood frequency analysis works, it is essential to understand the concept of return period.
