Finite Difference Method Runoff Modelling Using Voronoi Cells
Voronoi Diagram runoff modelling TIN IFDM
2015/10/9
Finite difference runoff modelling has usually been done using a regular grid representation of the terrain. This has various
disadvantages, as the regular pattern does not conform well to observed ...
Verification of a non-hydrostatic dynamical core using the horizontal spectral element method and vertical finite difference method: 2-D aspects

2014/4/10
Two-dimensional (2-D) finite-difference (FD) synthetics, which fill the gap between fast 1-D analytic synthetics and time-consuming full 3-D synthetics in our ability to model seismograms, have been u...
Finite Difference Method of Modelling Groundwater Flow
Finite Difference Method Groundwater Modelling Particle Tracking Algorithm Discretization Flow Rates Hydraulic Heads
2013/3/19
In this study, finite difference method is used to solve the equations that govern groundwater flow to obtain flow rates, flow direction and hydraulic heads through an aquifer. The aim therefore is to...
