The Influence of Deep-Seated Landslides on Topographic Variability and Salmon Habitat in the Oregon Coast Range, USA
… partly shaping the river ecosystem. But what processes shape the geomorphic template? Here, I examine how two hillslope processes dominant in the Oregon Coast Range, debris flows and deep-seated landslides, affect valley floor width and channel slope, key components of the geomorphic template …

Under what conditions do parallel channel networks occur?
… fluvial erosion and a slope-dependent model for hillslope processes. The parameters of the model were determined to imitate the real basins, and the average slope of the pre-existing surface was used for the slope of the initial surface. Based on these simulations, the model can also produce a …

Flood Processes in Semi-arid Streams: Sediment Transport, Flood Routing, and Groundwater - Surface Water Interactions
… combined with modeling are used to evaluate the processes of post-disturbance sediment transport, flood routing, transient bank storage, and stream disconnection. The major findings show: (1) Suspended sediment composition in floods following wildfire depends on the number, timing, and intensity …

Studying signatures of water on Mars at two macro and micro scales : orbital analyses of hillslope geomorphology and ChemCam calibration for surficial rock chemistry
… at two scales from two different disciplines: hillslope geomorphology and chemistry from laser-induced breakdown spectroscopy (LIBS). In the first set of studies on hillslopes, the expected differences in hillslope processes in extraterrestrial environments are explored. As on Earth, the major …

Modelling surface evolution coupled with tectonics
… Both SECs involve diffusion as approach for hillslope processes and the stream power law to reflect riverbed incision. The 1D SEC settles sediment that was produced by fluvial incision in the appropriate minimum, while the supply-limited 2D SEC DANSER uses a fast filling algorithm to model …

Climate variability and extreme hydro-meteorological events in the Southern Central Andes, NW Argentina
… Argentina, a region impacted by deep convection processes that form the basis of extreme events, often resulting in floods, a variety of mass movements, and hillslope processes. This region is characterized by pronounced E-W gradients in topography, precipitation, and vegetation cover, spanning …

Constraining tectonic and climatic controls on glacial/postglacial landscape evolution using numerical modeling
… is shaped by the interactions between surface processes, tectonics, and climate. During the Late 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 …

Soil-Landscape Modelling in an Andean Mountain Forest Region in Southern Ecuador
… pedogenetic, geo-morphological and hydrological processes. The resulting soil profile reflects the balance of these processes in its properties. Early conceptual models have by now resulted into quantitative soil-landscape models including soil variation and its unpredictability as a key soil …

Fluvial processes, beaver activity, and climate in the greater Yellowstone ecosystem and rock type control on hillslope morphology and soil development in the Sandia Mountains, New Mexico
… 1 is submitted to the journal Earth Surface Processes and Landforms. Chapter 2 will be submitted to the journal Climatic Change soon after this dissertation is published. Chapter 3 is already published in the journal Quaternary Research (November, 2011). Chapter 1 explores differences between …
