Report: A Framework for the Classification of Drainage Networks in Savanna Landscapes

The overarching aim of this research is to describe patterns of soils, vegetation and hydrology in the savanna landscapes in Kruger National Park (KNP) that are spatially organised at various scales by the configuration of drainage networks. Specific objectives were to: Develop a hierarchical conceptual framework within which the structure, function and dynamics of water-controlled ecosystems can be described, explained and predicted. The framework will include both drainage networks and hillslopes, so that linkages can be described and explored in a holistic manner across the entire landscape. Construct a spatially explicit, scaled and hierarchically nested classification of Kruger National Park landscapes, based on the conceptual framework. Explore the hydrological, geomorphological and ecological implications of the diversity and spatial arrangement of elements at each scale (representing an organisational level in the hierarchical model). Integrate the framework and classification into the Kruger Park management system as a test case for broader application.
