On the one hand, natural vegetation patterns result from the interplay between climate, soils and topography; on the other, vegetation in turn exerts important controls on the hydrologic and geomorphic processes in the basin, and contributes to the formation of landscape morphology over the long term.
This analysis reveals a transition in the dominant erosion process at the channel head mediated by vegetation cover. For the first time, we now can obtain surveys over broad areas that document topography at the resolution at which transport, erosion, and deposition processes operate.
More attention was paid to Slovakia. Agricultural intensification is defined as higher levels of inputs and increased output of cultivated or reared products per unit area and time [ 27 ].
Physical landscape patterns are often closely associated with biotic ones, ranging from the variation in forest type with upland elevation to riparian ecosystems tied to stream channels to the exquisite control of marsh vegetation by small changes in land elevation and wetting frequency.
These geopatterns comprise a diversity of scales and forms, and most show a fascinating mix of order and disorder. InNSF supported an international workshop on High-Resolution Topographic Data and Earth Surface Processes to explore how high-resolution topographic data can advance understanding of Earth surface processes Merritts et al.

However improved management practices and emerging technologies may permit a reduction in emissions per unit of food produced. Contamination of water by pesticides is widespread, and groundwater pollution due to pesticides is a worldwide problem [ 45 ]. The needs for better methods of assessing and predicting soil erosion and sediment supply at a wide range of landscape scales, and for clarifying concepts that underpin public policy on these matters, suggest an important role for research in Earth surface processes.
Reflections from deeply buried surfaces were extracted from a three-dimensional seismic volume to produce these maps of ancient seascapes.
