Effect of evaporation on land salinization after storm surge overtopping embankment

Embankment overtopping protection systems

For the last decades, the design floods of numerous embankment reservoirs were re-evaluated, and the revised spillway outflows are typically larger than those used in the original designs. As a result, a number of overtopping protection systems were developed for embankments and earthfill dams, with applications encompassing river dykes, coastal barriers for storm surge and tsunami protections....

Computational modelling of combined storm surge and wave overtopping of embankments

In this paper we investigate the process of embankment wave overtopping combinedwith overflow due to extreme surge levels that are above the embankment crest. AReynolds Averaged Navier-Stokes (RANS-VOF) model is employed to simulate thehydrodynamics. To investigate the success of the model at reproducing thehydrodynamic processes, the model is compared with experimental laborato...

Effects of Wind Erosion and Soil Salinization on Dust Storm Emission in Western Iran

Dust storms are known as hazardous problems in western part of Iran. Iraq is one of the main sources for dust storm arriving to the western part of Iran. The Radial Basis Function Network model (RBFN) has been used to assess wind erosion hazards in the source area of dust storms over several western Iranian cities. Normalized Difference Salinity Index (NDSI) was used to determine the changes in...

effect of oral presentation on development of l2 learners grammar

this experimental study has been conducted to test the effect of oral presentation on the development of l2 learners grammar. but this oral presentation is not merely a deductive instruction of grammatical points, in this presentation two hypotheses of krashen (input and low filter hypotheses), stevicks viewpoints on grammar explanation and correction and widdowsons opinion on limited use of l1...
