Numerical Modelling of Geomorphological Processes in Estuarine Waters
Numerical modelling of geomorphological processes in rivers, estuaries, harbours and coastal waters is an efficient means of predicting bed level changes for further use in planning the maintenance and management of these areas. Nowadays, quasi-3D models are increasingly popular, particularly with …

GEOMORPHOLOGICAL MAPPING OF THE K2 AREA, PAKISTAN USING GIS AND REMOTE SENSING
Geomorphological mapping assists in evaluating the polygenetic role of glaciation, mass movement denudation, and fluvial erosion in landscape development. A series of thirteen 1:100,000 geomorphological maps covering the area between Skardu and K2 were produced using field mapping and photography, …

Analysis and Modeling of Landscape Topography: Statistical Description and Evolution Under Natural and Disturbed Conditions
… soil fertility losses. Hence, understanding the geomorphological processes driving the evolution of landscapes under natural and disturbed conditions is key not only to define the main factors and feedbacks shaping the Earth's topography, but also to foresee the consequences of intensive land use …

Single grain detrital cosmogenic Ne-21 analysis: a new tool to study long-term landscape evolution
… which aspects of source area geomorphology and geomorphological processes can be inferred from frequency distributions of single grain detrital cosmogenic nuclide concentrations through the use of a combination of cosmogenic Be-10 and Ne-21 analyses and numerical modelling. The Gaub River study …

Aspectos físicos e o uso do solo na microbacia do rio da ribeira, município de Santa rita – PB.
… and loss of soil are part of these degenerative processes of the natural landscape. The Rio Ribeira’s watershed, located in Santa Rita, Paraíba, is a current example of such processes that are directly associated with the form of the land use. Actions arising mainly from the extensive planting of …

Factor influencing headcut migration within a cohesive Texas Black-Land gully.
… It is initiated by rill and inter-rill erosive processes and exacerbated by storm frequency and duration. Few studies have assessed the factors influencing headcut development in cohesive gullies, mainly due to the limitations posed by field instrumentation and the high shear strength of clay …

Assessment Of The Macroinvertebrate Assemblages From The Mesohabitats Of A Headwater Stream-Wetland Hydrologic Restoration In Eastern Kentucky
… functioning and thus the underlying fluvial geomorphological processes that create pools which are disrupted by channelization. Subsequently, improved hydrologic function may have led to increased habitat complexity, substrate stability, and organic matter retention. Post restoration …

Life history and secondary production of Cheumatopsyche spp. in a small Appalachian stream with two different land uses on its watershed
… showed evidence of disturbance related to both geomorphological processes and agricultural activities. There was higher annual accumulated degree days, and stream substrate particles were mostly mid and coarse gravel. The downstream section was surrounded by forest, with little evidence of human …

Systematic revision of the South American armored catfish genus Loricaria (Siluriformes: Loricariidae)
… of endemism provide some insight into past geomorphological processes that have influenced diversification in Loricaria and serves as a foundation for further tests of biogeographic hypotheses based on phylogenetic and geological evidence.

Assessing the impacts of riparian land use on gully development and sediment load : a case study of Nzhelele River Valley, Limpopo Province, South Africa
Human activities on land degradation have triggered several environmental problems especially in rural areas that are under developed. The main aim of this study is to analyse the contribution of different land uses to gully development and sediment load on the Nzhelele River Valley in the Limpopo …
