Determining overland flow hydrographs from sections of nonuniform width
… for uniform sections matched that of the kinematic wave to nearly 60 percent of the equilibrium discharge. It also corresponded well with Morgali's results and Izzard's measured hydrograph. When the model was applied to sections of nonuniform width it was found only the end ratio, defined …

Inherent Instabilities and Discontinuities: The Kuramoto-Sivashinsky Equation and a Suspension Flow as Exemplars
… equation, formulated as a perturbation of the kinematic-wave equation. This instability is invisible to regular matched asymptotic expansions, which, at small times, see no deviation in the leading-order solution from the kinematic-wave solution. However, by considering exponentially small …

Geomorphic modeling and routing improvements for GIS-based watershed assessment in arid regions.
… 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 routing at …

Simulation of hydrologic processes for surface mined lands
… hydraulic head at selected depth intervals. The kinematic wave approximation and the continuity of mass equation are used to route overland flow from the watershed. The model accurately predicts the distribution of water resulting from annual series of precipitation and potential …

Time characteristics of small watersheds in response to the probable maximum precipitation
… Missouri. Overland flow was simulated using kinematic wave routing and channel flow was simulated using dynamic wave routing.</p> <p>Lag time was defined as the time between the centroid of the excess rainfall hyetograph and the centroid of the direct runoff hydrograph.</p> <p>Rainfall depth, …

Urban hydrological modeling of the Malden River using the Storm Water Management Model (SWMM)
… used to calculate flow in the drainage system, kinematic wave routing was used. The results showed substantial internal flooding within the drainage system. Since such flooding has not been observed, this is an indication that the hydraulics portion of this model requires further refinement in …

Modeling the hydrologic and particulate loadings from paved urban surfaces
… drainage system. It was also found that the kinematic wave model could accurately model significant aspects of rainfall-runoff events in traffic-impacted watersheds provided that abstractions were incorporated into the modeling process. For this watershed the source of abstraction was …

Modeling and monitoring pathogen transport through vegetated filter strips
… the vertical movement of FC, a one-dimensional kinematic wave model was developed and used. Green and Ampt, Philip, and Schmid infiltration models were also applied to the vertical water flow movement. The models simulated the spatial and the temporal distribution of FC in runoff assuming an …

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 …

Evaluation of flow models and pollutant retention isotherms for their application to rain garden bioretention
… fields with respect to rain garden devices. The kinematic wave equation was chosen to model water movement in both the matrix and macropore regions as this provided a simpler alternative to more complex equations while still maintaining good accuracy. With regards to the modelling of heavy metal …

Seismic reflection imaging of near surface structures using the Common Reflection Surface (CRS) Stack Method
… methods for two real field datasets (P- and SH-wave)and two synthetic datasets that exhibited very large vertical velocity changes. Finally, I have proposed some original solutions that overcome several of the issues encountered when using CRS stack with near-surface data. The P-wave dataset was …
