ImageSegmentation, Indexing Feature Extraction, Feature Generation. This paper indicate that polarization channel based feature grouping followed by a multi-classifier decision fusion framework performs markedly better than traditional SLDA and LDA based dimensionality reduction, followed by a single-classifier. Results illustrates the classification maps generated using the proposed MCDF frame...

The progressive constriction of the Mississippi for navigation since 1837 has caused bottom erosion in some stretches. In others the bottom oscillates up and down with time. The high stages rise much more rapidly. Constriction of the river channel causes flooding and makes floods higher; thus navigation works degrade the protection afforded by levees. The combination of navigation works and lev...

Usually, various kinds of floods are distinguished based on the origin or on the main processes. Basically, the cause of the flood can be overflow over the banks of the main channel, direct runoff or failure of a levee or other structure. Flash floods are typical of steep beds and / or high intensity rainfalls. In mountain areas, they can be associated to debris flows or highly concentrated bed...

This study investigated erosion during infiltration and overflow events considered different grain sizes hydraulic conductivity properties; four experimental cases were conducted under saturated conditions. The importance of understanding flow regimes experiments including their distinct characteristics, shear stresses, mechanisms in assessing the potential for levee failure are discussed. mech...
