3D GIS urban runoff mechanism: A new perspective using volumetric soft geo-object

With the enhancement of the current GIS data model into a 3D dynamic simulation form, the importance of urban runoff mechanism could be visualized significantly. Such enhancement provides a valuable step for urban runoff modelers by visualizing complex streamflow routing, overland flow, channel fl...
