Estimating the magnitude of profile scale factor is currently based on the assumption that beach profiles are in equilibrium condition. However, this assumption cannot be applied to all beach profiles. In this article, a boundary based profile scale factor is proposed that through a normalized coordinate system leads to a unique global profile scal...

This article reports a study in which drag coefficient is defined more comprehensively. The coefficient is defined as a function of particle nominal diameter, gravitational acceleration, the ambient fluid kinematic viscosity, and the particle shape. This new definition is different from the conventional definitions proposed in the literature based...

Tide is an essential factor in coastal engineering. The relationship between all forces and factors causing tides are very complex. Traditionally, tides are predicted through harmonic analysis, where a tide level at any time instants is estimated based on the past records. Predicting tide levels based on previously recorded data, strongly suits the...

An accurate estimation of carbon dioxide (CO2) solubility in brine is of great significance for industrial applications such as quantifying CO2 sequestration in subsurface formations, CO2 surface mixing, and different CO2-based enhanced recovery methods (EOR). In this research, four different data-driven/machine learning techniques, extreme gradien...

The subaerial zone of the beach is a highly dynamic area that supports recreation and different habitats; as such, it has been the focus of many past studies. Accordingly, this paper reports a study of the assessment of the erosion and accretion over subaerial beach profiles and their relationship to the upper beach width. To this end, the erosion...

The importance of shoreline protection has attracted researchers in terms of finding new and applicable methods. The equilibrium planform concept is being widely used and modified over more than two decades. Cyprus has relatively high economical dependency on its sandy shorelines, which are mostly natural headland bays. The fact that most of the ri...

Beach profiles vary significantly based on sediment supply and hydrodynamic, aeolian, and anthropogenic influences. Successful management of beach and dune resources is heavily based on understanding and classifying beach profile shapes based on their dominant features. As such, the highly dynamic shape of beach profiles has motivated researchers t...

This article reports the interaction between groundwater and surface water sources based on diurnal head fluctuations. The model uses the well-known Fick’s second law to numerically estimate the pressure head variations in heterogeneous aquifers. The developed numerical model can examine the effects of both stream level sudden diurnal and gradual v...

In this study, a methodology has been proposed that can be used to estimate the peak unit discharge for all the watersheds in the northern part of Cyprus. Thus, the Soil Conservation Service method was used to determine the unit hydrographs of 366 watersheds available in the study area. Through the Digital Elevation Model with a spatial resolution...

Sediment transport calculations are used globally in the numerical models that coastal managers, scientists and engineers use to assess and forecast coastal change. Most of the existing sediment transport equations were defined based on experimental results using siliciclastic sands. Yet these equations are applied to all types of sand, including c...

A stepped spillway, which is defined as a spillway with steps on the chute, can be used to improve the energy dissipation of descending water. Although uniform stepped spillways have been studied comprehensively, non-uniform stepped spillways need more attention. In the interest of maximum energy dissipation, in this study, non-uniform stepped spil...

In this article, the ability of estimating the weight and the failure load of a structure through image processing has been investigated. To this end, the well-known civil engineering practice, spaghetti bridge, has been used as a test structure. To set up uniform experiments and to simplify the construction process, only 2 dimensional bridges were...

The variety of methods used to solve the traveling salesman problem attests to the fact that the problem is still vibrant and of concern to researchers in this area. For problems with a large search space, similar to the traveling salesman problem, evolutionary algorithms such as genetic algorithm are very powerful and can be used to obtain optimiz...

This article reports a search space splitting pattern that can be applied to genetic algorithms in order to ensure that the entire search space is investigated. Hence, by keeping the genetic algorithm simple, in a reasonable time and with a high degree of accuracy, the initial solutions can be improved toward the global optimum point. The simplicit...

This study aimed to conceptually analyze the change in the magnitude of offshore sediment yield, wave energy, and offshore dislocation of sediment particles on coastal regions in the presence of coastal vegetation. This was achieved by comparing the simultaneous physical changes at coastal zones that were partly covered with vegetation while the re...
