The momentum equation in the kinematic wave model is a power law equation and involves two kinematic wave parameters. It is a common practice to use Manning's equation to calculate the kinematic. The model has been developed from basic principles. It is a portion of a larger project to develop a modeling tool to assess the impact of urban development on the temperature of coldwater streams. Heat transfer and runoff processes on an impervious surface were investigated for both dry and wet weather periods.
A simple method is presented for assigning Manning roughness coefficients n to overland flow segments in kinematic wave models. The resulting n‐value for each subcatchment reflects its imperviousness and its land approach has been incorporated into a kinematic wave model, and its application is here demonstrated on a catchment in Singapore. To evaluate tsunami hazards with strong locality in urban areas, this study developed a novel tsunami inundation model based on nonlinear shallow water wave equations and a porous body model (PBM). By applying a kinematic boundary condition that includes both porosity and surface permeability of the porous medium, the proposed model could accurately incorporate .

The application of a kinematic wave model to urban surfaces By R. Gunst and C. Kidd Download PDF (2 MB)Author: R. Gunst and C. Kidd. Finite element approximation of one-dimensional kinematic wave equations. The principle of spatial discretization for the one-dimensional kinematic wave model using the FEM method is dividing the river basin into “strips” that represent flow direction on the surface of the water flow.
Each strip is then divided into computational Cited by: 1. Flow routing is conducted by using the kinematic wave method in a one‐dimensional scheme. For energy processes, short‐wave radiation is based on observation or deduced from sunshine duration, long‐wave radiation is calculated according to temperatures, latent and sensible fluxes are computed by the aerodynamic method and surface.
From Figurea point on the flow-density curve uniquely defines the operating condition of a stream of speed of a kinematic wave carried by the traffic, w, is the tangent to the curve at this the underlying flow-density relationship is triangular, finding kinematic wave speeds is greatly simplified.
The kinematic wave approximation to the full Saint-Venant equations is often used in many surface and subsurface water models due to its simplicity in application.
However, this model fails when backwater effects, ponding, or flow on reverse slope occurs in the local scale. Furthermore, due to the complexity in the surface geometry and the. Kinematic-Wave Model.

The book is comprehensive and yet written in a basic way enabling practitioners to pick out relevant sections and apply them to real problems.
It also contains a valuable collection of charts and equations as well as simple computer programs for modelling catchment runoff and stream flow using the kinematic equations.

In this paper, only the time/area model is included as an exemplification of applying automated calibration scheme. 2 THE OBJECTIVE OF MODEL. The kinematic-wave model is one of a number of approximations of the dynamic-wave model. The dynamic-wave model describes one- dimensional shallow-water waves (unsteady, gradually varied, open- channel flow).
A kinematic wave model is developed to study surface irrigation. Depending on the variability of infiltration and the kinematic wave friction parameter, three cases are distinguished.
Explicit analytical solutions are obtained for the case when infiltration is constant, and a possible approach is suggested for the case when it is not.
A solution to the kinematic wave equations for overland flow routing where the lateral inflow term is determined from a constant rainfall rate and the infiltration model of Philip is presented. The solution utilizes the method of characteristics, and while it is not completely analytical, it is reduced to a simple numerical procedure which does.
A distributed hydrological model, water and energy transfer processes (WEP) model, is developed to simulate spatially variable water and energy processes in watersheds with complex land covers.
In the model, state variables include depression storage on land surfaces and canopies, soil moisture content, land surface temperature, groundwater tables and water.

Kinematic wave modeling methods are gaining wide acceptance as a fast and accurate way of handling a wide range of water modeling problems.
This is the first book to provide a thorough reference to the application of KW methods to such problems as the spatial representation of watersheds, overland flow routing, and channel flow routing. Abstract This paper examines runoff dynamics and heat transfer during rainfall over urban surfaces, in particular pavements.
A kinematic wave approach is combined with heat storage and transfer schemes to develop a model for pervious and impervious pavements. Kinematic Wave Method: "This routing method solves the continuity equation along with a simplified form of the momentum equation in each conduit.
The latter requires that the slope of the water surface equal the slope of the conduit. The maximum flow that can be conveyed through a conduit is the full normal flow value.sloping planes.
