Texto completoSand grains transported by the desert wind move in successive jumps on a granular bed. During the impact, they can eject other grains. To study this process, we collided a single bead on a packing of identical grains. We reported the experiment for a broad range of incident speeds and impact angles. The results show that, although the incident bead dissipates less energy for grazing impacts, the number of ejected grains is smaller in this case. The mean values of the ejection speed and ejection angle are, to first order, insensitive to the kinematics characteristics of the incident bead. In addition, the total kinetic energy of ejected beads is directly proportional to the fraction of incident energy given

Texto completoThis Research aims to characterize the aeolian processes on a beach-dune system under prevailing offshore winds. To achieve this, the site of Leucate-Plage has been chosen due to the Tramontane, an offshore wind blowing more than 70 % of thetime. This field site is composed of a small foredune on a microtidal area sometimes hit by intense marine storms. These characteristics make this site one of the representative coastal areas present on the Gulf of Lion. This research demonstrates, using observations and modelisations, that a small dune can nonetheless have significant effects on aeolian dynamics. This work highlights an area of wind separation and recirculation in the leeward region of the dune during perpendicular wind. However, this does not cause transport towards the dune foot because, regardless of the incident wind speeds, the threshold shear velocity for grain movement is never reached in this recirculation zone. the dune at Leucate-Plage is human-made, this cause longitudinal variations in its morphology due to different construction methods. These variations create variable disturbances in wind flow and aeolian transport. In some cases, with gentler dune slopes, the wind is not separated but only deflected and much less attenuated when passing over the dune, allowing sediment transport in the lee side. In all cases, the wind is accelerated approaching the dune crest, especially when the wind is perpendicular, reaching up to twice the speed of the incident wind. Aeolian sand transport depends on many control factors, this work focused on the beach grain size and histemporal variability, often neglected in studies. The results show that this parameter can have significant consequences on the observed and calculated transport rates. In an environment with wide variations in grain size over time, annual transport rates can differ by more than 75 times from those observed depending on the grain size applied to the transport formula. In the case of offshore winds, the distribution of wind speeds and aeolian sand transport fluxes is unequal across the beach profile, with an increase observed moving away from the dune. Thus, transport rates can easily exceed 100 kg/m/h at the berm. The consequence of this seaward aeolian transport can cause significant erosion of the beach, depending on wind speeds and beach's grain size state. This erosion can reach values greater than 50 cm on the berm and 20 cm on the beach in a few hours. This thesis highlights the impact of offshore winds on a microtidal beach and the influence of an artificial dune and its construction methods, on wind flow and aeolian sediment transport. It also warns about using an appropriate grain size for calculating aeolian transport rates in a heterogeneous and variable grain size environment

Texto completoSeveral experiments aimed at elucidating the effects of ridge and runnel morphology on aeolian transport were carried out on macrotidal beaches on the Opal Coast. The results show that in spite of a potentially large wind fetch with onshore winds given the width of these beaches, the effective fetch is generally limited to the upper beach terrace and to the first ridge on the upper beach, and is especially segmented by the runnels which may act as efficient sand traps. The results also highlight highly variable trapping rates. The rates were commonly weak and this could be a limiting factor in terms of beach-dune sand transfers, especially in view of the fact that the dominant winds on the North Sea sites are essentially obliquely offshore. The short term topographic surveys and digital elevation models have highlighted the efficiency of dune management and rehabilitation schemes. Differential contour maps generated by these surveys bring out the stages of foredune accretion

Texto completoStorms are by far the major hazard damaging the trees. However, trees do not just behave passively in the wind. They sense their own strains under the influence of an external force such as wind andrespond by modifying their growth and the mechanical properties of their tissues. But this process, called thigmomorphogenesis, has mainly been studied in very young trees in controlled conditions. This thesis aims to expand for the first time such studies at the scale of a forest stand in order to understand how adult trees acclimate to the wind in natural conditions by adapting their growth. It relies on an experimental set up in a regular stand of beech (Fagus sylvatica) which have never be thinned. The wind speed, the longitudinal strains and the radial growth of fifteen pairs of trees with contrasted sizes and wind exposures (split into two social status, dominant and suppressed trees) were monitored for one year. By controlling the strain intensity experienced by the trees, either by guying or by additional bendings, we show that the trees respond only to mechanical stimulation caused by rather strong winds with a return period higher than a week. This response leads however to a very strong increase in radial growth. And it follows a law of mecano-sensing uniform among the trees, regardless of their sizes. We then studied the effects of the strain regulation on the mechanical design of the trees and the potential risk of stem breakage. Despite the contrasted sizes and wind exposures, the strain regime remained uniform within the beech stand, in agreement with the hypothesis of an optimal mechanical design often inferred but never validated in its mechanism. Finally, the constitutive equations of a possible growth model dependent on wind are proposed and discussed

Texto completoEProgresses in civil engineering allow to design more and more light and slender structures. The results of this is a higher sensitivity of these structures to fluctuating wind sollicitations. A vibratory behaviour can then lead civil engineering works to failure. The aim of our work is to develop numerical tools which enable to assess the response of slender structures to wind turbulence. The natural wind is a three-dimensional stochastic process which can be described by probalistic modèls. Fluctuating aerodynamic forces are divided into two parts : the buffeting forces, directly linked to the wind turbulence, which are associated to the concept of aerodynamic admittance ; aeroelastic forces, generated by structure vibrations which can induce a unstable dynamical behaviour
