Small Scale Aeolian Processes and Landform Response
… motion. The deposited grains produce various landforms from centimeter-scale sand ripples to meter- or kilometer-scale dunes and dune fields on terrestrial and extraterrestrial surfaces. In this dissertation, I investigated three subjects concerning small-scale aeolian processes and landforms: …

North Gale Landform and the Volcanic Sources of Sediment in Gale Crater Mars
… into the origins of a previously unidentified landform north of Gale Crater, Mars (North Gale Landform, NGL) using remotely sensed datasets and morphological mapping has determined that it is a volcanic construct that collapsed and produced a hummocky terrain deposit to the south. …

Assessing glacier retreat and landform production at the ‘debris-charged’ snout of Kvíárjökull, Iceland
… for the study of glacier fluctuations and landform production in response to climate change due to its diverse glacial legacy and its archive of aerial photographs that provide accurately dated records of glacier retreat and landform evolution from 1945. This study focuses on Kvíárjökull, …

Earth to Earth : reconciling earthen dwellings with eroding loess landform : the case of Loess Plateau in China
… an earthen construction tradition in loess landform territories. The Loess Plateau in China has been suffering from heavy soil erosion. Soil erosion is caused by the scale of the hill and valley watershed and exacerbated by the scale of earthen dwellings. These dwellings are mostly populated …

Geographic Information System Topographic Factor Maps for Wildlife Management
… information system (GIS) was used to create landform measurements and maps for elevation, slope, aspect, landform index, relative phenologic change, and slope position for 3 topographic quadrangles in Virginia. A set of known observation points of the Northern dusky flying squirrel (Glaucomys …

Ecological Drivers of Plant Community Composition in a Patterned Fen at Seney National Wildlife Refuge, Michigan
… variation in geomorphology, vegetation, fen landforms, and water chemistry create a variety of unique peatlands across the Northern Hemisphere. In the Great Lakes region, patterned fens have been extensively studied in northern Minnesota, but largely ignored in Michigan. The purpose of this …

Geomorphic Consequences of Hydroelectricity and Transportation Development near Celilo Falls, Lower Mid-Columbia River, Washington
… and hydroelectricity developments to eolian landforms on the floodplains and adjoining slopes have not been studied. Focusing on 2,800 acres near Celilo Falls, this study 1) establishes a baseline condition of eolian landforms from 1805 to 1900; 2) conducts an air photo increment analysis …

Suitability of Aster and SRTM dems, and satellite imagery in detailed geomorphological mapping in Dzanani Area of Makhado Local Municipality, Limpopo Province, Republic of South Africa
… of whether satellite data are accurate for landform mapping to how surfaces of interest can be defined from remote sensing data, since earlier approaches of mapping are deemed costly and tedious. The aim of this study is to assess the suitability of ASTER and SRTM DEMs, and satellite imagery …

The Naming, Identification, and Protection of Place in the Loess Hills of the Middle Missouri Valley
… no longer accurately reflects the physical landform or public perception of its size. In addition, the diminished definition undermines efforts to develop effective public policy to protect the Hills. This study proposes a new boundary for the landform based on both physical evidence and …

Periglacial Geomorphological Mapping of the Comanche Peak Area . Mummy Range, Larimer County, Colorado
… of wild flowers are the dominant vegetation. All landforms are developed in Precambrian granites, gneiss, and schist of Precambrian X (between 2500 m.y. - 1600 m.y.) and Y (between 1600 m.y. - 900 m.y.) ages. Most of the study area was not glaciated during late Pleistocene time. Headward erosion …

Changes in abundance and distribution of Protea caffra in the central and northern Drakensberg as a consequence of climate and land use change
… the extent and rate of population change. The landform units were demarcated on each photograph according to their catenal position, aspect, elevation and the extent of rocky cover. Geological parameters for each landform unit were obtained from GoogleEarth, climatic data from the South African …

Developing a classification system for Western Cape wetlands
… characteristics (drainage patterns, landform), hydrological pattern and timing of water availability, were recorded during winter and summer for each studied wetland. Water samples were also collected at the wetlands and analysed for ion and nutrient concentrations and samples of …

Hydrologic Response of Alternative Valley Fill Reclamation Designs
… regions of the western U.S. is geomorphic landform design. Geomorphic reclamation is based upon creating landforms that resemble the mature surrounding watersheds in both topography and hydrologic response. The objective of this research was to predict the hydrologic response of a mine site …

Stratigraphy and Site Formation at the Sanders Site (45 KT 315), Kittitas County, Washinton
… aeolian and colluvial processes. Periods of landform stability are marked by soil formation. Sediments preserved on-site appear to contain a relatively complete record of the Holocene, whereas across the creek at 45KT726, the earlier Holocene sediments have been stripped away by fluvial …

Prioritization of Carolina Bays as Mitigation Projects from a Herpetofaunal Perspective
Carolina bays are landform features of the southeastern United States that contain isolated depressional wetlands. These unique ecosystems are particularly valuable for herpetofauna and are at risk of being extirpated from the landscape because of recent legal developments. There are few available …

Spatial and temporal variation In greenhouse gas flux as affected by mowing on grasslands of hummocky terrain In Saskatchewan
… an unmowed control were imposed on six different landform elements. Carbon dioxide, CH4 and N2O were measured every 7-10 days from spring until fall for two years with closed, vented chambers. Soil physical characteristics, weather and plant community characteristics were measured. Landform …

Adaptation of an architectonic tradition for a sustainable future in the Middle East: a case study of three building typologies in Riyadh City.
… The particular chosen sites were Addiriyah, Landform house and Al Madinah. The first and the last sites provided an insight into traditional architectonic forms, while Landform House depicted transitory or hybrid housing patterns. A questionnaire was distributed to two-hundred potential …

Landscape forcing mechanisms on Quaternary timescales: The Tabernas Basin, SE Spain
Quaternary landform features and their associated sedimentary assemblages (river terraces and alluvial fans) often provide important records of long-term landscape evolution. The reconstruction of global terrace sequences has enabled the identification of numerous external and internal forcing …
