Reduction in channel capacity can trigger an increase in flood hazard over time. It represents a geomorphic driver that competes against its hydrologic counterpart where streamflow decreases. We show that this situation arose in the Guadalquivir River (Southern Spain) after impoundment. We identify the physical parameters that raised flood hazard in the period 1997–2013 with respect to past yea...

In 1995, Stanley Trimble and Alexandra Mendel published a review article focusing in the role cattle play in influencing geomorphic processes, the cow as a geomorphic agent – a critical review. Trimble and Mendel looked at the voluminous, largely unconnected, body of literature on the various means by which cattle affect landscapes. One of the major goals of Trimble and Mendel’s work was to put...

1. Rivers are subject to thresholds of several types that define significant changes in processes and morphology and delimit distinctive riverine landscapes and habitats. Thresholds are set by the conditions that govern river channel process and form, amongst which the most important are the flow regime, the quantity and calibre of sediment delivered to the channel, and the topographic setting ...

The last maximum glacier advance in many mountain ranges appears to have predated the last maximum advance of the Wisconsinan continental ice sheets (-20,000 years B.P.). Published evidence from widely spaced localities in North and South America, Europe, Asia, and Hawai'i suggests that some mountain glaciers extended farther during one or more stades early in the last glaciation, roughly 115,0...

High-resolution digital elevation data acquired by airborne laser scanning (ALS) for the Denton Hills, along the coastal foothills of the Royal Society Range, Transantarctic Mountains, are examined for applications to bedrock and glacial geomorphic mapping. Digital elevation models (DEMs), displayed as shaded-relief images and slope maps, portray geomorphic landscape features in unprecedented d...

Intelligent, automated analysis of data is a critical task in modern data-intensive sciences. The work presented in this thesis is a contribution to this body of research, focusing on automatic geomorphic characterization of planetary surfaces (particularly Mars). We present a framework for automated generation of geomorphic maps from topographic data. Our approach first segments the topographi...

Geomorphic models have a wide range of capabilities in terms of prediction, and this range is part of the reason for this volume. Haff [1996] pointed out that landscape-scale geomorphic models are fundamentally ill-suited to precise prediction and that reductionism is ill-suited to landscapescale problems. Geomorphic models run the gamut of spatial and temporal scales and modeling approaches, f...
