A series of adjacent alluvial fans coalescing in a basin at the foot of a mountain range. Most often gully erosion is recognized as a geohazard (Ionita et al., 2015). For example, before 1980 both the Chihuahua and Sonora deserts in northern Mexico and the Tabernas desert and other badlands in SE Spain were ill considered by local inhabitants. They increase soil cohesion and resistance to erosion (including rill and gully erosion), surface mass movement and creeping; they increase soil porosity. Figure 3.2. Describe processes represented by the model Basin and Landscape Dynamics (Badlands) is a parallel TIN-based landscape evolution model, built to simulate topography development at various space and time scales. The literature concerning geotourism in badlands and areas highly dissected by extensive gullies is limited. A final section considers the implications of these challenging processes for badland models. Besides, the rapid evolution of landforms following rainfall of different intensities in badlands enables interpretation of landscape evolution in the short term and to compare prevailing geomorphic processes in different seasons. Excessive grazing, poor irrigation and soil sealing by buildings contribute to the loss of ecosystem functionality and equilibrium. Numerous low, rolling hills are interspersed with well-defined high ridges, floodplains, valley flats, and small local basins. bar Thus, changes in badland hydrological response are expected, and these changes will be different depending on the region because they behave differently in different climates (see Chapter 2). English term or phrase: badlands: Definition from Glossary Of Geography: Very irregular topography resulting from wind and water erosion of sedimentary rock. A more detailed discussion of factors crucial for calanchi and biancane development is available in Section 6 of this chapter. The Encyclopedia of Geomorphology defines badlands as ‘deeply dissected erosional landscapes, formed in softrock terrain, commonly but not exclusively in semiarid regions’ (Harvey, 2004, p. 45). Further erosion of ravine beds gives rise to canyons. Badland, area cut and eroded by many deep, tortuous gullies with intervening saw-toothed divides. Warke et al. Click on a word above to view its definition. Badlands form when soft sedimentary rock is extensively eroded in a dry climate. Soil erosion converts a fertile land into a bad land. (2) Why do tourists visit badlands? Such badlands are typically found in Mediterranean, semiarid and arid regions of the globe. One of the most well known badlands areas in the US is Badlands National Park of South Dakota. The data we will discuss come from many disciplines, from earth and plant sciences, to history and archaeology, and derive from field surveys and archive sources. Wojciech Zgłobicki, ... Zheng’an Su, in Badlands Dynamics in a Context of Global Change, 2018. Identifying their relevance as sediment sources is critical for … Badlands: Irregular topography that has been damaged by water and wind erosion of sedimentary rock. Piccarreta et al. These observations lead to a consideration of the possibilities for remediation of piping-prone materials. Even small differences in grain size and permeability affect the sensitivity of (for example) sandstone to weathering processes. Juliane Krenz, Nikolaus J. Kuhn, in Badlands Dynamics in a Context of Global Change, 2018. We use cookies to help provide and enhance our service and tailor content and ads. Landscape (aesthetic) values are among the basic criteria for selecting tourist destinations. Rate! The mixed grass prairie of the central United States is actually a transition zone between the more arid shortgrass prairie to the west and the more moist tallgrass prairie to the east, but because of its size is considered worthy of separate distinction. From: Badlands Dynamics in a Context of Global Change, 2018, Juan F. Martínez-Murillo, Estela Nadal-Romero, in Badlands Dynamics in a Context of Global Change, 2018. This chapter aims to (1) show the variability in badland hydrological response under different climate conditions and across scales (Section 2); (2) provide a global perspective of the factors and processes and their interactions driving badland runoff response (Section 3); (3) examine the main impacts expected from forecast climate change on badland runoff under the different conditions in which badlands occur (Section 4); and (4) identify the knowledge gaps which must be filled to be able to understand badlands response to rainfall and off-site impacts under a global change scenario (Section 5). Local lithology, regional to local tectonics, climate oscillations and the effects of both extreme natural events and human action play a dominant role in determining whether these four instability factors converge in a landscape, ultimately to lead to the initiation, stabilization and rejuvenation of badlands.
