Soft geo-objects have been useful for investigating spatial patterns of Geographic Information System (GIS) based overland flow mechanism, but have suffered from a lack of abilities to visualize the dynamic as- pects of volumetric Streamflow Generating Processes (SGP) realistically. Existing 2D soft geo-objects data model are insufficient for analysing the dynamism of Infiltration Excess Overland Flow (IEOF) volumetrically, which is the major process contributing towards SGP. At present, there is still no unifying evidence available that provides a coherent explanation for the integration of 3D Volumetric Soft Geo-objects (VSG) data model for infiltration excess mechanisms. This study aims to visualize areas and overland flow volume generated from IEOF process dynamically using 3D VSG data model, which is driven by Green-Ampt infiltration equation. In- clusion of 3D VSG data model would offer substantial effort towards representing 3D soft geo-objects simulat- ing IEOF dynamically within a catchment, estimating overland flow capacity, routing and diversions to reduce landslides and flood disaster.
