Kinematic wave model
Webthe wflow_routing model (a kinematic wave model that can run on the output of one of the hydrological models optionally including a floodplain for more realistic simulations in areas that flood). the wflow_wave model (a dynamic wave model that can run on the output of the wflow_routing model). In gravity and pressure driven fluid dynamical and geophysical mass flows such as ocean waves, avalanches, debris flows, mud flows, flash floods, etc., kinematic waves are important mathematical tools to understand the basic features of the associated wave phenomena. These waves are also applied to model the motion of highway traffic flows. In these flows, mass and momentum equations can be combined to yield a kinematic wave equ…

Web30 apr. 2024 · Based on the kinematic wave theory and Van Aerde single-regime flow model, a model for estimating the congestion propagation speed for the basic road segment was developed. Historical traffic flow data were used to analyze the time variant characteristics of the urban traffic flow for each road type. Web1 jan. 1994 · Kinematic-wave models are applicable to overland flow where lateral inflow is continuously added and is a large part of the total flow. For channel-routing applications, the kinematic-wave model always predicts a steeper wave with less dispersion and attenuation than actually occurs.
WebThe present paper assessed the use of variable kinematic two-dimensional elements in the dynamic analysis of Lamb waves propagation in an isotropic plate with piezo-patches. The multi-field finite element model used in this work was based on the Carrera Unified Formulation which offers a versatile application enabling the model to apply the desired … WebThe kinematic wave model is a simplified description of the complex flow processes on a hillslope. Beven (1981) derived a condition under which it might be considered a suitable approximation to Darcian flow in the saturated zone, but it is worth noting that it is not necessary to view the kinematic wave model as an approximation to Darcian flow.
