Influence of Wind on Suspended Matter in the Water of the Albufera of Valencia (Spain)
2021
Wind is one of the factors that has a great influence on suspended matter in lakes, especially in shallow lagoons. In order to know how wind affects the water in Albufera of Valencia, a shallow coastal lagoon, the measured variables of turbidity and transparency have been correlated with the estimates by processing Sentinel-2 satellite images with the Sen2Cor processor. Data from four years of study show that most of them are light to gentle easterly breezes and moderate to fresh westerly breezes. The results obtained show significant correlations between the measured variables and those obtained from the satellite images for total suspended matter and water transparency and with the averag…
An efficient framework for the elasto-plastic reliability assessment of uncertain wind excited systems
2016
Abstract In this paper a method to efficiently evaluate the reliability of elastic-perfectly plastic structures is proposed. The method is based on combining dynamic shakedown theory with Subset Simulation. In particular, focus is on describing the shakedown behavior of uncertain elasto-plastic systems driven by stochastic wind loads. The ability of the structure to shakedown is assumed as a limit state separating plastic collapse from a safe, if not elastic, state of the structure. The limit state is therefore evaluated in terms of a probabilistic load multiplier estimated through solving a series of linear programming problems posed in terms of the responses of the underlying linear elast…
Shallow waters as ecological corridors: preliminary data on wind-exposure, physico-chemical features and vegetation structure of the Western Sicilian…
2004
The study was carried out in the Natural Reserve of Trapani and Paceco saltworks shallow system (western Sicily: 37° 52’ North; 12° 28’East).The main goal is to deepen our understanding of whether the alteration of the complexity of these particular ecosystems is manifested through a consequent reduction of the number of migrant species and their density. To achieve this, we focalized our attention on organic matter fluxes (in terms of origin and availability for apex consumers), and on the density and distribution of aquatic birds.
