The Amazon river is subject to major geomorphological changes between the hydrologic periods of flood and dry. Such changes can be mapped and detected by remote sensing techniques. In this context, this research had as objective to evaluate the dynamics of this great fluvial system, in the stretch between the cities of Manaus and Itacoatiara, in the period of 20 years. The results showed the pr...

In the desert of Abarkoh Basin, Central Iran, the influence of playa-lake level fluctuations on recent sedimentation mode of a terminal ephemeral fluvial-fan system and adjacent lacustrine/aeolian sediments of a playa fringe environment has been investigated. The surface geomorphology-sedimentology and its relationship with shallow subsurface sediments along a >25 km transect, has been studied....

Historical and modern scientific contexts are provided for the 2006 Binghamton Geomorphology Symposium on theHuman Role in Changing Fluvial Systems. The 2006 symposium provides a synthesis of research concerned with human impacts on fluvial systems — including hydrologic and geomorphic changes to watersheds — while also commemorating the 50th anniversary of the 1955Man's Role in Changing the Fa...

Introduction: The recent observations about different waterand ice-related features on Nepenthes region of Mars [1] [2] [3], and the evidence of changes on the Oceanus Borealis’ water level on this region [4] [5] inspired the work here presented. What are exactly the water-related landforms (glacial, periglacial, fluvial, etc) existing in this region of Mars? How are they spatially distributed?...

Coastal Research, Special Publn. 34, pp 449-458, 2001 Entrance closure has been identified by the local coastal communities as one of the more important management problems for the small barrier estuaries. The paper describes...

[1] A numerical model has been developed to predict the evolution and degree of incision and deposition by fluvial channels on the continental shelf during sea level cycles. Rainfall-runoff, mass wasting processes, and fluvial sediment entrainment and transport are simulated using the detachment-limited model of Howard [1994] on a grid that represents the morphology of the continental shelf and...

Available online 10 April 2013 Fluvial systems include natural and human-created barriers that modify local base level; as such, these discontinuities alter the longitudinal flux of water and sediment by storing, releasing, or changing the flow path of those materials. Even in the absence of distinct barriers, fluvial systems are typically discontinuous and patchy. The size of fluvial discontin...

Javoří hory Mountains is a part of Intra Sudetic Basin that belongs to the Permian-Carboniferous section of the Bohemian Massif, whose geological evolution was strongly influenced by volcanic activity. In the Pleistocene epoch cryogenic processes modeled the mountains significantly (frost cliffs, gelifluction streams), which resulted, in connection to the slope orientations, in substantial moun...

Introduction: This investigation focused on Warrego Valles, a region of well-developed valley systems located in Thaumasia Planum of the southern highlands at ~42°S, 267°E. Some previous workers interpreted the valley systems in this area as being of fluvial origin [1-3], while others focused on sapping [4-6] or hydrothermal activity [7-10] as formative mechanisms. It is clear that no single mo...
