“…a substantial portion of wind speeds falling in the more energetic categories that are bene cial for higher energy yields. PS demonstrated consistency in wind speeds, particularly in the 4-6 m/s range, which constitutes 42.79% of the wind speed occurrences, same concluded by(Elsharkawy et al, 2016). This consistency is advantageous for steady and predictable wind power generation.…”

There is now no wind park operating along the Egyptian Mediterranean Coast, hence the goal of this study is to find some ideal circumstances for such projects. In order to fulfill this aim, wind data from five coastal meteorological stations were used for the evaluation. These are, respectively from west to east, Mersa Matruh (MM), Ras El-Tin (RE), Abu Qir (AQ), Port Said (PS) and Arish (Ar). The wind regime data (speed and direction) at 10-m height extended over 16 years from January 2007 to December 2022, with 0% missing record. The Weibull distribution function with its different parameters was used to characterise the wind energy along the Egyptian Mediterranean coast. Results revealed that the dominant wind direction along the Egyptian Mediterranean coast is the NNW to N wind, except at PS where the dominant wind is S. The wind seeped range 4–6 m/s dominated the entire coast except at Ar, where it is reduced to 2–4 m/s range. The analysis of wind power density revealed significant insights into the potential for wind energy generation in the region. The overall analysis showed that MM, AQ and PS are potentially the most suitable locations for wind energy projects. However, the high variability at AQ site requires robust system designs to manage the fluctuating wind conditions. MM and PS might be more suitable for projects prioritizing stability and consistency over maximum energy output. Arish, having the lowest wind power density might be less suitable for large-scale wind energy projects but could still be considered for smaller installations or in combination with other renewable energy sources.

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

Background Currently, there is no wind park operating along the Egyptian Mediterranean Coast. Therefore, this study aims to find suitable locations for such projects. Wind data from five coastal meteorological stations were used. These are Marsa Matruh (MM), Ras El-Tin (RE), Abu Qir (AQ), Port Said (PS), and Arish (Ar), in that order from west to east. The wind regime dataset, comprising velocity and direction measurements at a 10-m elevation, was collected from January 2007 to December 2022 (16 years), with a complete record of all data points. The Weibull distribution function, along with its different parameters, was used to characterize wind energy along the Egyptian Mediterranean Coast. The coefficient of determination (R2), root mean squared error (RMSE), and relative root mean squared error (RRMSE) for the Weibull parameters, along with the relative percentage errors (RPE) for the wind power density were calculated to assess the concordance between outcomes derived from observed data and those predicted by the Weibull function. Results Results revealed that the dominant wind direction along the Egyptian Mediterranean Coast was the NNW to N wind, except at Ar where the dominant wind was S. The wind velocity range of 4–6 m/s dominated RE, AQ, and PS. At MM and Ar, this was reduced to 2–4 m/s. The analysis of wind power density outlined significant insights into the potential for wind energy generation in the region. The overall analysis showed that AQ and PS were potentially the most suitable locations for wind energy projects. However, the high variability at the AQ site required robust system designs to manage the fluctuating wind conditions. PS might be more suitable for projects prioritizing stability and consistency over maximum energy output. Although Arish, characterized by its lower wind power density, may be less conducive for large-scale wind energy projects, it could still be viable for smaller installations or when integrated with other renewable energy sources. Conclusions The different statistical indices reflected good model fitting, displaying the reliability of the Weibull distribution as a tool for preliminary wind resource assessment along the Egyptian Mediterranean Coast and facilitating accurate predictions of wind power availability.
