most of river engineering problems are complicated and need to be analyzed by three dimensional models of flow and sediment transport. considering the fact that computers and numerical methods with great ability of flow and sediment transport simulation are developing quickly, using numerical modeling by engineers is inevitable. nevertheless, before application, numerical models need to be veri...

Behaviors of liquids in two-dimensional (2D), lyophobic nanoenvironment were investigated experimentally by using a surface-modified, graphene-based nanoslit composite (GBNC). Different from previous reports on one-dimensional (1D) nanofludic behaviors, the infiltration pressure of 2D nanofluid is not dependent on the infiltration volume, leading to a flat infiltration plateau in the sorption i...

The Talbot–Ogden hydrology model provides a fast mass conservative method to compute infiltration in unsaturated soils. As a replacement for a model based on Richards equation, it separates the groundwater movement into infiltration and redistribution for every time step. The typical feature making this method fast is the discretization of the moisture content domain rather than the spatial one...
