چکیده

Abstract This work delivers comprehensive information on the statistical metrics of sea level in Port Said Harbor, which can be used for mitigation plans and protection measures its vicinity. The study hourly data extended over 10 years from January 2002 to December 2011. A descriptive analysis monthly variations was introduced. T_Tide package obtain astronomical constituents, are turn calculate form factor specify tidal cycle main water characteristics. meteorological calculated by subtracting elevation recorded level. impact factors observed fluctuations more obvious winter than summer. effect conditions possible largest range $${~}^{1}\!\left/ \!{~}_{3}\right.$$ 1 3 that impact. No extreme year, considered when annual mean deviates regression line twice standard deviation, appeared during decade investigation. return periods design lifetime risk were calculated. highest probabilities occurrence concentrated levels between 70 80 cm, while lowest below 5 cm above 110 cm. all ranged 0.4 4.5 years. coastal structures vicinity Harbor may have a short only 50 most pronounced (75 cm). It is recommended consider present results upon designing constructions within territory.

Reliability, return periods, and risk under nonstationarity

Water resources design has widely used the average return period as a concept to inform management and communication of the risk of experiencing an exceedance event within a planning horizon. Even though nonstationarity is often apparent, in practice hydrologic design often mistakenly assumes that the probability of exceedance, p, is constant from year to year which leads to an average return p...
