Exploring equifinality in a landscape evolution model
… disciplines, and is thought to be likely in landscape evolution models (“LEMs”) also, as they incorporate many process parameters of uncertain value. LEM equifinality, if pervasive, would be a serious obstacle to falsifying working hypotheses and would frustrate landscape evolution research, …

Topographic asymmetry and climate controls on landscape evolution
Landscapes are expected to evolve differently under the influence of different climate conditions. However, the relationship between landscape evolution and climate is not well understood. I investigate the relationship between landscape evolution and climate by using natural experiments in which …

Quaternary landscape evolution, pedology, and geoarchaeology in central Texas.
… Creek provides a view of late Quaternary landscape evolution in central Texas along a low-order tributary. The late Quaternary history of central Texas is a complex story of climate and hydrologic changes, sediment supply, and human interaction. From >60 ka near the transition of MIS 5 to …

The landscape evolution, geochemistry and biogeochemistry of Kangaroo Island
This work provides a landscape context and framework for the use of regolith and vegetation in mineral exploration on Kangaroo Island, South Australia. Regolith field observations and the production of a regolith–landform map have improved constraints on the ferricrete plateau formation and also on …

Effects of differential rainfall on the dynamics of landscape evolution
The field of landscape evolution modeling focuses on the evolution of the structure of landscapes over geologic time. The elevations of rivers, valleys, hills, and mountains make up the structure of the landscape. Generally, these elevations change due rock uplift as well as incision. Rivers are …

The Lincolnshire marsh : landscape evolution, settlement development and the salt industry.
The coastal wetland, known as the Lincolnshire Marsh, is investigated in order to understand the ways in which people in the past exploited coastal zones. This research into a previously neglected area has tested the validity of' Rippon's (2000) three-part model ofcoastal strategies - exploitation, …

Sinkhole Form as an Indicator of Process in Karst Landscape Evolution
Although exhaustive studies of solution rate variability have traditionally dominated karst geomorphology they have, so far, failed to identify reliable form-process relationships. This study creates a methodology for precise definition of the morphology of the basic karst unit, the sinkhole; and …

Investigating the Effects of Lithology on Landscape Evolution Processes across Scales
… have long observed the influence of lithology on landscape form and evolution. However, the specific mechanisms by which this is accomplished are not well characterized. Here, I investigate the role of lithology in landscape evolution processes across spatial and temporal scales and geomorphic …

Landscape evolution of the Umbum Creek Catchment, Western Lake Eyre, Central Australia.
Landscape evolution is important for mineral and petroleum exploration concepts, especially in dryland continental settings. This study seeks to understand the main issues and controls on landscape evolution that have produced the regolith and young sediments around the western side of Lake Eye, in …

Constraining tectonic and climatic controls on glacial/postglacial landscape evolution using numerical modeling
… Cenozoic, repeated glaciations have affected the landscapes of many high-latitude regions and mountain ranges around the world, including both active subduction belts and stable continental interiors. The glacial/interglacial climate perturbations have caused repeated transitions between glacial …

A nonlinear river meandering model and its incorporation in a landscape evolution model
… model mechanisms. A channel-hillslope integrated landscape development (CHILD) model incorporates the TSRM model. The CHILD model represents the landscape as an irregular, Delaunay triangulated mesh of landscape nodes that may be moved, deleted, or added to accommodate meandering channels that are …

Headcut retreat resulting from plunge pool erosion in a 3D landscape evolution model
… pool mechanism was implemented in an existing 3D landscape evolution model (CHILD) that includes other mechanisms of erosion like fluvial erosion and diffusion. The effects of headcut retreat on the landscape and of the landscape on the headcut retreat mechanism were investigated to learn what …

Evaluation of Coupled Erosional Processes and Landscape Evolution in the Teton Range, Wyoming
The evolution of mountain landscapes is controlled by complex interactions between large-scale tectonic, surficial and climate conditions. Dominant processes are attributed to creating characteristic features of the landscape, but topographic features are the cumulative result of coupled surficial …

Late Quaternary landscape evolution and environmental change in Charwell Basin, South Island, New Zealand
… and holistic analysis of late Quaternary landscape evolution and environmental change in Charwell Basin using terrain analysis, loess stratigraphy, soil chemistry and paleoecological data. The study contributes new understanding of New Zealand landscape and ecosystem responses to regional …

Understanding topographic evolution of continents with landscape evolution simulations: the case of North America
… within the sub-lithospheric mantle. Here I use landscape evolution simulations to investigate the mechanisms of continental topographic histories. First, I designed synthetic landscape evolution experiments to study the responses of surface processes to end-member geodynamic mechanisms that …

Pliocene-Pleistocene landscape evolution in south-central Chile : interactions between tectonic, geomorphic, and climatic processes
Landscapes evolve in a complex interplay between climate and tectonics. Thus, the geomorphic characteristics of a landscape can only be understood if both, climatic and tectonic signals of past and ongoing processes can be identified. In order to evaluate the impact of both forcing factors it is …
