Zusammenfassung |
For spatially explicit hydrological modelling an algorithm was
required that works as a cellular automata on irregular meshes. From
literature it was found that the usual algorithms applied for this
purpose do not route the water flow correctly between adjacent cells.
In this study the hydraulic linking between mesh cells is done by
calculating the flow cross section between the mesh cells. The flow
cross sections are positioned in the centre of the mesh edges and
are perpendicular to the local gradient of the digital elevation
model. The presented algorithm is simple in its implementation and
efficient in computation. It is shown that the proposed algorithm
works correctly for different synthesised hill slope shapes. |
