Abstract: Bathymetries are a fundamental element in civil engineering when the work to be made must be based on the study of submerged terrain. In this sense, they are necessary in many situations: marine constructions such as dikes, docks, etc; dredging volume control, river flood study, etc. Traditionally bathymetries have been a difficult and costly job both in time and effort. However, over time and supported by the development of topographic and geodetic technologies, they have undergone an important transformation and progress in both precision and performance. In this sense, this article reviews the evolution of the different topographic techniques used over time, emphasizing the investigation and study of the accuracies and efficiencies typical of them; especially those that are used today. In this way, it can be concluded that, with the appropriate methodology, currently, bathymetries can be made with centimeter accuracy and with an efficiency that can exceed several square kilometers e

Abstract: Due to the rapid expansion of wind energy and the growing numbers of wind turbines constructed in earthquake areas. It is required to perform more research works for a better understanding of this issue. Accordingly, this humble study is needed. This study considered the onshore Vestas (V47/660) wind turbine tower which is located at Zafarana Wind Turbine Farm in Egypt. The foundation of this tower is designed as a large rigid reinforced concrete type and constructed in an active seismic region. The main research question is; what is the effect of the soil type, seismic frequency and amplitudes on the foundation and the tower translation movement? Also, the research hypothesis believes that the softer the soil is the greater its effect on tower and foundation deformations. Accordingly, this study has been planned. The aerodynamic effect induced due to the turbine blades has been excluded, while the static loads of the turbines as well as the seismic effect of the regions have been cons
