Landscapes respond to climate, tectonic motions and sea level, but this response is mediated by sediment transport. Understanding transmission of environmental signals is crucial for predicting landscape response to climate change, and interpreting paleo-climate and tectonics from stratigraphy. Here we propose that sediment transport can act as a nonlinear filter that completely destroys (“shre...

The question whether it is time for marine morphodynamic models to take into account the 3-D nature of water and sediment motion is discussed starting from practical demand and the state-of-the-art in basic knowledge and model development. This leads to the observation that there is a clear practical demand, and that suitable software environments and some 3-D model components exist, but that t...

We read with great interest the review by Leliefeld et al. [1] published in Critical Care on the role of neutrophils in immune paralysis during systemic inflammation (SI). This is of high clinical importance since immune paralysis potentially increases susceptibility to new infections or may cause inability to clear existing infections, leading to detrimental outcome. One mechanism proposed for...

Sediment transport and, consequently, the beach profile changes in swash zone are important to overall sediment budget and evolution because hydrodynamic condition this is complex. One of morphodynamic difficulties estimating accretion erosion above mean water level. Although there have been considerable studies investigations into morphodynamic, numerical models for predicting rate limited. Th...

Coastal area morphodynamic models are prone to severe errors arising from various sources, including: (1) the use of empirical sediment transport formulae (Pinto et al., 2006); (2) the reliability of the data used to feed the models; (3) the use of simplifying physical assumptions; (4) the error propagation between the various modules. Since these errors can be significant, the usefulness and c...

in this research work the classification of the southern coasts of the caspian sea is performed using sedimentary and morphodynamic indices. this includes field study of morphodynamic characteristics of the shore structures. field measurements include in situ samplings of sediments and actual observations of structures on site. these field activities were done along six transects in the dry coa...

How a fertilized egg develops into a multicellular organism remains one of the most challenging questions in biology. Novel techniques provides unprecedented high-resolution data on the spatiotemporal dynamics of the developing embryo. However, interpretation of these data requires both wet lab experiments and computational modeling (Oates et al., 2009). Here, we present a new modeling environm...
