Geomorphology of the Cape Peninsula
It is axiomatic that we live in a world characterized by opposites. We are thus aware of day and night, winter and summer, uplift and subsidence, lithosphere and hydrosphere, upland and lowland areas, past and present - the list is endless. This dichotomy or ambivalence is present in this study as …

Glacial Geomorphology of southern Alberta, Canada
During deglaciation from the Last Glacial Maximum three terrestrial ice streams within the south western sector of the Laurentide Ice Sheet competed and coalesced in southern Alberta; the High Plains Ice Stream (HPIS), Central Alberta Ice Stream (CAIS) and the east lobe. The ice streams are …

Bio-physical controls on tidal network geomorphology
… insights into the bio-physical controls on the geomorphology of tidal networks. To this end, a combination of remote sensing, modelling and field activities was employed. A geo-spatial analysis was performed at Queen Mary, University of London (UK), to address the variability of tidal network …

Channel geomorphology relationships for the Beaver Creek watershed
The proposed Appalachian Corridor H will be built through some of the most rugged terrain in West Virginia. The Corridor H section from Davis to Bismarck passes through the Beaver Creek watershed, located in Tucker County, West Virginia, which has been heavily affected by historic mining, …

Glacial Geomorphology of the Eastern Antarctic Peninsula Shelf
During the last glacial maximum, grounded ice from the expanded Antarctic Peninsula Ice Sheet extended across the continental shelf. Grounded and flowing ice carved a distinctive array of glacial geomorphic features into the seafloor, which were gradually exposed as the ice pulled back. The recent …

Fluvial geomorphology and paleofloods in arid central Australia
This thesis examines the fluvial geomorphology of the Todd River(9,300 km2) in arid central Australia. It describes the morphology, motphostratigraphy, dimentary characteristics and chronology of the modern flood plain and paleoflood complexes, and discusses the geomorphic effects of high magnitude …

Holocene Geomorphology of the Macdonald and Tuross Rivers
The floodplains that grade to the estuaries along the New South Wales coast primarily record a history of valley aggradation induced by post-glacial sea level rise. However, post-glacial sea level along this coast has both risen, then fallen, relative to the land during the Holocene due to …

Climatic and geodynamic influences on ocean island geomorphology
With homogeneous bedrock, dramatic rainfall gradients, and remnant surfaces that constrain their age, initial topography, and vertical motions relative to sea level, volcanic ocean islands provide an exceptional natural experiment in landscape evolution. Analyses traversing gradients in island …

Hydrogeology and geomorphology of two structurally dissimilar terranes in Pennsylvania
<p>Eight watersheds in Pennsylvania, draining areas of uniform climate and lithology, but different geologic structure, were studied for their geomorphic, geologic, hydraulic, and hydrologic characteristics.</p><p>Low streamflow characteristics, defined by base-flow recession curves, and streamflow …

Searching for the ideal river? New directions in geographical geomorphology
Geomorphology’s development as a scientific subject has produced increasingly sophisticated insight into the physical processes shaping the earth’s surface. It is increasingly apparent, however, that understanding contemporary environments requires equal attention to the processes through which …

The evolution of the Congo- Kalahari Watershed: African mega-geomorphology
… causes of Africa's present day continental geomorphology.

Geomorphology and ecohydrology of water-limited ecosystems : a modeling approach
The role of vegetation in shaping landforms and how these landforms respond to disturbances are the subjects of this work. A numerical model is developed to help develop a mechanistic understanding of the hydrological, ecological and geomorphic interactions in water-limited ecosystems. The growth …

Soil geomorphology of the eastern Sevilleta Long Term Ecological Research Site
<p>Soils in the arid to semi-arid piedmont landscapes of central New Mexico were examined in order to evaluate surficial processes and landscape evolution in the central Rio Grande Rift. These soils were found to contain key information regarding pedologic and geomorphic responses to climate …

Quantitative geomorphology and hydrology of the Cass River Basin, New Zealand
<p>The Cass River drainage basin is in the Southern Alps in the central part of the South Island of New Zealand. The Alps are composed of complexly folded greywacke which is still actively rising. The basin has been modified by several glacial advances during Pleistocene time. </p><p>The Cass basin …

Vernal Pool Mapping and Geomorphology in the Appalachian Mountains of Pennsylvania
… have vernal pools, but a regional inventory and geomorphology assessment is needed. My research is split into two independent parts focusing on the higher elevation areas of this region to determine vernal pool distribution and characteristics. Vernal pools were mapped using a LiDAR based …

Wave-driven geomorphology of Pacific carbonate coastlines: from landscape to wavelength scale
The shallow marine ecosystems of coral atolls and the human communities they support are among the most vulnerable to anthropogenic climate change. Sea-level rise threatens to inundate low-lying reef islands, tropical cyclone intensification threatens islands with flooding and erosion, and ocean …

Geomorphology and Dynamics of a Sand Wave in Lower Chesapeake Bay, Virginia
<p>A single, more or less isolated, sand wave in a sand wave field recently discovered in the lower Chesapeake Bay, Virginia, was studied intensively for morphology, sedimentology and in terms of dynamic processes. The morphologic investigation consisted of bathymetric surveys of the sand wave …
