Erosion by a one-dimensional random walk.
We consider a model introduced by Baker et al. [Phys. Rev. E 88, 042113 (2013)] of a single lattice random walker moving on a domain of allowed sites, surrounded by blocked sites. The walker enlarges the allowed domain by eroding the boundary at its random encounters with blocked boundary sites: attempts to step onto blocked sites succeed with a given probability and convert these sites to allo...
متن کاملChannel erosion due to subsurface flow.
We study the physical processes that create eroded channels and drainage networks by doing laboratory experiments. The apparatus consists of a sloping granular bed inside a 90 cm 119 cm 30 cm acrylic box. The granular material consists of 0.5 mm diameter glass beads. Water is fed from a reservoir in the back and the pressure is maintained at a constant level. The water seeps through the porous ...
متن کاملOn the modelling of internal soil erosion
Suffusion is the process whereby fine particles are moved locally an transported through a coarse layer. This is a bulk erosion, which corresponds to a source term in the mass balance equations. This bulk erosion is counter intuitive, as erosion is basicaly an interfacial process. We suggest a framework within suffusion in a clayey sand can be viewed as a clay/water interface erosion at the mic...
متن کاملSeepage-Induced Streambank Erosion and Instability:In Situ Constant-Head Experiments
The effects of seepage on streambank erosion and failure are less understood compared to fluvial processes, especially the linkage between surface water and groundwater mechanisms. Field data are needed to validate laboratory seepage erosion and instability conclusions and to understand how engineering tools and methods may be applied to field conditions. An innovative trench injection system w...
متن کاملOne Dimensional Internal Ballistics Simulation of Solid Rocket Motor
An internal ballistics model has been developed for performance prediction of a solid propellant rocket motor. In this model a 1-D unsteady Euler equation with source terms is considered. The flow is assumed as a non-reacting mixture of perfect gases with space and time varying thermo physical properties. The governing equations in the combustion chamber are solved numerically by using the Steg...
