A framework for the classification of drainage networks in savanna landscapes
Expanded Title:The character and behaviour of rivers depends on the nature of their catchment. Hillslopes and channels are generally studied separately. A holistic approach is needed. Landscape patterns of water, soil, vegetation and topography are not easy to disentangle, but in semi-arid environments the distribution of vegetation and soils often occur in patterns that are both cause and consequence of topographically controlled water fluxes. A hierarchical framework, based on an integration of aquatic and terrestrial perspectives, was developed to facilitate the synthesis of knowledge across many disciplines focusing on spatial and temporal scales relevant to conservation management (101 - 103 km2 and seasons to decades). Topography is an important control on the distribution of water and hence on the distribution of landscape patches and it is highly organised in space. The classification demonstrates how the framework addresses landscape complexity that involves multiple feedbacks within and across scales. Spatially explicit landscape classification is central to both systematic conservation planning and strategic adaptive management
