Sentence examples for evolution of the bed from inspiring English sources

The physical problem is modeled through the shallow-water equations coupled with the Exner equation to describe the time evolution of the bed profile.

The implicit time advancing is compared in terms of accuracy and computational time with the explicit approach for one-dimensional and two-dimensional sediment transport problems, characterized by different time scales for the evolution of the bed and of the water flow.

Observations confirm a rapid and complex evolution of the river bed (erosion and aggradation), and provide information about the dynamics of the sediment transfer from the production areas to the ocean.

After experiments, 2D cross-sections and 3D images were obtained, which provide a convenient way to obtain global and quantitative information on the evolution of the sludge bed structure during the entire drying process.

The evolution of bed composition profiles from the fixed to the fully fluidized state, where the gas drag force first balances the particulate bed weight, makes clear that full fluidization is constantly associated to the achievement of practically thorough mixing.

Our simulation results for the bed evolution of the river under the 100-year flood reveal complex sediment transport dynamics near the bridge piers consisting of both scour and refilling events due to the continuous passage of sand dunes.

In particular, in the best simulations obtained by using the empirical bed-load power law, the time evolution of bed profiles is in good agreement with the measured data of aggradation and degradation tests, having small average relative errors.

Figure 1 gives the evolution of the number of ICU beds belonging to participating ICUs, the number of patients and among them, the number of ventilated patients.

However, often the Eulerian flow fields of the entire granular bed are more useful– they can be used to study segregation, for instance, or the evolution of the free surface of the bed.

Some of the aspects considered included the evolution of the shape of the coffee bed during brewing, correlations observed between the final bed shape and the quality of the brewed coffee and the use of a single jet or multiple jets (shower head) to deliver water to the coffee bed.

The effects of SGS tensor on evolution of fluidized bed are found in various aspects.
