Abstract
Gully erosion is known to affect soil productivity, limit land use, and to pose threats on infrastructure in many parts of the world. Gully erosion has been largely neglected because it is di�cult to model and visualize its effects. Many gullies grow rapidly to large sizes, making effective control technically di�cult and often too expensive. To assess the susceptibility of soils and substrates to gully erosion, the triggering factors must be identi�ed and analyzed. For this study, a simulation of gully development over time was implemented in Python based on the topographic characteristics of the test watershed, soil properties, and measured runoff. The full simulation GIS was tested on a gully in the KwaThunzi region, South Africa. The results are very promising and allow a 2D/3D visualization of the time series of gully evolution.
期刊介绍：
The Journal of Spatial Science publishes papers broadly across the spatial sciences including such areas as cartography, geodesy, geographic information science, hydrography, digital image analysis and photogrammetry, remote sensing, surveying and related areas. Two types of papers are published by he journal: Research Papers and Professional Papers.
Research Papers (including reviews) are peer-reviewed and must meet a minimum standard of making a contribution to the knowledge base of an area of the spatial sciences. This can be achieved through the empirical or theoretical contribution to knowledge that produces significant new outcomes.
It is anticipated that Professional Papers will be written by industry practitioners. Professional Papers describe innovative aspects of professional practise and applications that advance the development of the spatial industry.
