A Novel Framework for Simulating Particle Deposition With Moving Bedforms

Previous modeling studies of hyporheic exchange induced by moving bedforms have used a reference frame, typically corresponding to an individual bedform. However, this approach is not suitable for simulating the and accumulation immobile fine particles beneath bedforms, which commonly occurs in sand-bed streams, as both stationary features must be considered. Here we present novel simulation framework that may represent arbitrarily shaped, generally aperiodic mobile within frame. We combine with particle tracking successfully reproduce observations clay deposition sand beds, resulting development low-conductivity layer near scour zone. find increased bedform celerity filtration lead shallower depth more compact layer. While causes deposit, reduces flattening flowpaths.
