Shallow Water Wave Propagation in Open Channel Flow
… can be treated as propagation of shallow water waves in channel flow. It can be mathematically approximated by the Saint-Venant equations or by simplified wave approximations, including the kinematic wave, noninertia wave, gravity wave and quasi-steady dynamic wave models. These approximations …

Geomorphic modeling and routing improvements for GIS-based watershed assessment in arid regions.
… network for multiple consecutive events. A diffusion-wave routing subroutine was developed for the Kinematic Runoff and Erosion Model (K_INEROS2) using a four-point iterative solution to the modified variable-parameter Muskingum-Cunge (MVPMC4) technique. It was tested against kinematic-wave …

Three-Dimensional Volume Averaged Soil-Moisture Transport Model: A Scalable Scheme for Representing Subgrid Topographic Control in Land-Atmosphere Interactions
… flow model at a large scale, a 1-D Diffusion Wave (DW) surface flow model interacting with the 3-D VAST model, is developed for the comprehensive terrestrial water and energy predictions in LSMs. For the implementation of the model, the mixed numerical scheme using a time splitting …

Spatial Variability in Seepage from Unlined, Open Channels
… often an important factor, a new model using the diffusion analogy to the shallow-water (Saint-Venant) equations was developed as a step toward estimating seepage losses from unlined channels.Comparison of numerical models showed that a 1D model can be useful when a simple, comparatively low-cost …

The Effect of Anomalous Resistivity on the Electrothermal Instability
… ETI growth through modification of the magnetic diffusion wave. The impact of AR on nonlinear ETI is explored through pulsed-power simulations of a dielectrically coated solid metallic liner surrounded by a low-density vacuum contaminant plasma.

Analysis of flood hazard under consideration of dike breaches
… influence on the hinterland inundation and flood wave propagation lack comprehensive consideration. This study focuses on the development and application of a new modelling system which allows a comprehensive flood hazard assessment along diked river reaches under consideration of dike failures. …
