The paper concerns with the stream-channel landforms and processes, related to the specific conditions (slope, reduction of the solid discharge because of the human intervention, the variations of the discharge). In addition, the paper points out
the settling processes and landforms on the loess deposits of the Chilia natural levee. - (M. Vârlan).
Changing fluvial style of periglacial lowland rivers during the Weichselian Pleniglacial in the eastern Netherlands in Periglacial processes and landforms.
Analysis of the fluvial deposits occurring in the Weichselian basin fills in the Twente region contributes valuable information to the interpretation of last Glacial paleoenvironments. Although quantification of paleohydrologic data is difficult
, if not impossible in these deposits, the fluvial architecture provides sufficient clues for a general interpretation of the fluvial system in terms of discharge regimes.

The Hexi Corridor is a Cenozoic foreland basin system on the northeast margin of the Qinghai-Tibet Plateau. The structure is characterised by reverse faults trending NNW or WNW. This paper focuses on the response of alluvial landforms to tectonic
Riparian vegetation distribution patterns and diversity relative to various fluvial geomorphic channel patterns, landforms, and processes are described and interpreted for selected rivers of Tuscany, with emphasis on channel evolution following
human impacts. Multivariate analysis revealed distinct quantitative vegetation patterns relative to six major fluvial geomorphic surfaces. Species richness increases from the channel bed to the terrace and on heterogeneous riparian areas, whereas species
Plusieurs traits caractéristiques de lits fluviaux pour les cours d'eau situés dans le nord de l'oblast de Tioumen sont distingués. Les plus répandus sont les rivières à méandres.

The Late Cenozoic landform development history of east Africa is explained insufficiently by the available landform genesis concepts. Late Cenozoic plain formation in East Africa was an episodic event caused by contemporaneous erosion and deposition
near base level. It is therefore proposed to elaborate the etchplanation concept with fluvial dynamics. Late Cenozoic planation events in East Africa were triggered by a major base level rise due to the combined effects of eustatic sea level rise
This paper examines riparian vegetation patterns in relation to fluvial geomorphic landforms in five near-natural river reaches within ten years of a catastrophic flood. In summer 2007, vegetation along with other environmental variables
was collected on particular landform types (bars, islands, banks, floodplains and terraces). The analyses show that the key environmental determinants of riparian vegetation variation are the fluvial-geomorphic surfaces. The results suggest that many bottomland
species of woody and herbaceous vegetation have predictable distribution patterns that correspond with observable fluviallandforms. - (EN)

Valley stretches abandoned by watercourses at Quaternary, represent district landforms of the fluvial erosion-accumulation relief in the northern part of the Bohemian Upland. Four abandoned valleys and numerous Ohře River meanders were discussed

of the semi-arid southwestern United States. Channel-equilibrium conditions control stability of the coincident fluviallandform and attendant vegetation pattern throughout the continent. In most situations, riparian-vegetation patterns are indicative
Relations among vegetation, processes, and landforms are described here for representative streams of four areas of the United-States: high-gradient streams of the humid east, coastal-plain streams, Great Plains streams, and stream channels
of specific landforms and, thus, of ambient hydrogeomorphic conditions.

This paper examines the influence of hillslope processes, and the landforms that result from them, on channel dynamics within upland watersheds of the Great Basin of central Nevada. The AA. demonstrate that modern channel incision, and variations
in erosional and depositional processes observed along the valley floor, are directly related to the history of hillslope sediment production and landform development during the mid- to late Holocene.
Studies on the geomorphological features of the fluvial plains in Japan focusing the distribution on the geomorphological land classification and its application

This paper is in reality a research on the drainage basin of the Tutova river and concerns with the landforms and geomorphic processes. The valley is located in the Moravian Tableland, in conditions of homoclinal structure, with weak, rocks (sand
and clay), of Sarmatian and Pliocene ages. The A. discern three types of landforms : structural landforms (high plateaus, subsequent valleys and cuestas), sculptural landforms (hills, versants), that lies on over 90 % of the drainage area and are affected
by erosion and landslides, accumulative landforms, represented by flood plain and terraces, the last with a fragmentary disposition. - (M. Vârlan).
This paper aims to explore the process-landform relationships and potential genetic links between duricrust formation and Kalahari valley development, and hence assess the possible influence and implications of groundwater weathering and erosion
