Making the world differently: prospective uses of emerging technologies to inform river science and management
7. Dezember 2016, Gary Brierley

Working with nature is a key premise of effective approaches to river science and management. Emerging technologies give us an amazing capacity to develop place-based understandings of landscapes. In this talk I will present an overview of prospective uses of emerging technologies to inform river science and management. Building upon principles such as ‘Respect diversity’, ‘Work with change’ and ‘Know your catchment’, I will discuss ... more

International Lecture 2015


Messy Rivers are healthy Rivers
12. Jänner 2015, Ellen Wohl

I examine factors that create physical complexity, and the implications of complexity for habitat abundance and diversity, sensitivity and resilience to disturbances, retention of water, sediment and nutrients, and connectivity within the riverine system and landscape. Effective river restoration involves characterizing natural complexity, understanding its effects on ecosystem function, and assessing the degree to which it can be restored. ...mehr

The legacy of 19th century gold mining in Fraser River
08. Jänner 2014, Mike Church

The geomorphic impact of 19th century placer mining along Fraser River is studied by estimating the volume and grain size distribution of excavated sediment, evaluating the transport potential for the sediment in Fraser River, and discussing the relation between placer waste sediment and observed morphodynamics of the lower river. ...mehr

International Lecture 2013


Invisible Geomorphology: The Geophysics and Geochemistry of Erosion
29. April 2013, Niels Hovius

Much of geomorphology and what it is concerned with is not seen. By employing techniques and approaches borrowed from other Geosciences, and by considering the far field effects of geomorphic processes, we can better resolve the dynamics of landscapes and increase the visibility of Geomorphology.  For example, seismological techniques can be used to determine what happens where in a landscape, when and with what magnitude. ...mehr

International Lecture 2012


Uncovering the potential of statistical tools in geomorphology
14. Mai 2012, Alexander Brenning

Statistical tools are critically important for geomorphological research and practice. Among the milestones of geomorphology that required such tools are Horton's stream law, the Universal Soil Loss Equation, and the Hjulstrom-Sundborg curves. Today, whether landslide susceptibility is modeled or frequency-magnitude relationships of floods are analyzed, statistical tools allow geomorphologists to examine environmental controls and make predictions while assessing the underlying uncertainties. ...mehr

International Lecture 2011


Should we trust the sedimentary record?
11. April 2011, Tom Coulthard

Sedimentary records are widely used to infer causes of change in drainage basins. These are predominantly climate change, tectonics and land cover changes. However, recent work has suggested that internal non linear – or autogenic – processes can cause considerable variation in sediment delivery on their own.  ...mehr

International Lecture 2010


Are we overlooking the Geomorphic Dimension of Global Change?
9. Juni 2010, Antonio Cendrero

Concern about global change has focussed basically on climate and biodiversity, but changes affecting the earth’s surface have received limited attention. Concepts such as human geomorphic footprint, human geomorphic pressure and global geomorphic change have not made their way into the public or general scientific opinion; only into some geomorphologic circles. ...mehr

International Lecture 2009


The Balance of Nature and the Nature of Balance
18. Mai 2009, Jonathan Phillips

Concepts of steady-state equilibrium in geomorphology (as well as in
ecology and other sciences) are inextricably tied to a “balance of nature”
perspective which postulates normative, self-maintaining states. Recent
work on complexity in geomorphic systems, however, shows that there
are no goal functions in earth surface systems ...mehr


International Lecture 2008


The Role of Mountain Geomorphology in Global Change
11. Juni 2008, Olav Slaymaker

Three of the fundamental drivers of global change are relief, hydroclimate/
runoff and human activity. Mountain systems make a disproportionately
large contribution to our understanding of global change because the spatial and temporal variations of all three drivers of change ...mehr


International Lecture 2007


Sediment Budgets and Fluvial Geomorphology
23. April 2007, Stanley W. Trimble

Sediment budgets describe the input, transport, storage, and export of
sediment from a geomorphic system. Because all aspects of the system
are affected, sediment budgets have been considered to be an organizing
framework in fluvial geomorphology. ...mehr
