The AA. review the factors contributing to low sediment output in coastal plain rivers and complicating efforts to determine sediment yield to the coast, with particular emphasis on the deceptively simple problem of defining the mouth or outlet
of the river. They also seek to explore the role of transport capacity (in addition to accommodation space) in alluvial storage and buffering, with particular emphasis on channel slope. This work is based largely on a review of the literature
Impacts of breaching on a bar-built estuary, example of the Senegal River new mouth monitored with satellite imagery from 2003 to 2010
This paper presents the results of a survey of an estuary in Senegal since a human-induced breach was opened in a bar at the mouth of the embayment in October 2003 to reduce the effect of a major flood event. The evolution of the new mouth's width
has been analysed using a Landsat time series of 94 scenes, covering the period 2003-2010. This series is complemented by recent high resolution Alos-PRISM data, and very high resolution Ikonos data. The AA. focus on the consequences for the new mouth
The form of the delta fans at the mouths of the rivers on the Namibian coast is analyzed. The processes leading to the origin and evolution of the features are postulated. Some alternative ideas are explored. - (AJC)
Sedimentary processes in the river-dominated Mvoti estuary, South Africa
The Mvoti River enters the Indian Ocean on the Natal coast of South Africa. The aims of the paper are a) to describe the geomorphology of the Mvoti river-mouth area, b) to outline sedimentary processes in the lower reaches of the river, c
flood height, sedimentary facies data, rainfall and river discharge. It is shown that the decrease in rainfall index during the drier period (1987-1997) is well-correlated with the reduction of the Calçoene River discharge and jointly with increasing
tidal amplitude favored the increase of migration rate of the mud bank and erosion profile along the littoral. This was followed by the increase of the Calçoene River discharge and jointly with decreasing tidal amplitude during the wetter period (1997

Within the context of the new age control, the purposes of this paper are to: 1) identify, map and correlate fluvial terraces along the lower Susquehanna River; 2) assign ages to the terraces by downstream correlation to the fluvial stratigraphic
dunes fields are recognized. This study suggests that the aeolian sedimentation is a relatively recent phenomenon at the Quaternary strandplain of the São Francisco River.
The Yellow River delta is a very dynamic system and fluctuates in response to the alluvial regime, tide and storm surges. The deposits in the delta consist mainly of silt with a diameter of about 0.02 mm, which is highly erodible and differs

Wave-induced longshore currents and sea level changes during the last 7 000 years played an important role in the construction of the Quaternary coastal plains adjacent to the present Paraiba do Sul rivermouth. The river acted as a hydraulic groin

The influence of the Three Gorges Project on the mouth bar of the Yangtze River estuary. Mathematical simulation and prediction of erosion and siltation
The species still exists in this river basin, as well as in the Rhône, close to the mouth of the Drôme, forming two population isolates. The scarcity of otters in this area is probably not ascribable to changes in water quality or prey availability
A conceptual model of depositional, rather than erosional, tidal channel development in the rapidly prograding Skagit River Delta (Washington, USA)

at the rivermouth, vegetation colonization created marsh islands that splintered the river into distributaries. Examination of large-scale channel network geometry of such systems should therefore consider distributaries and blind tidal channels part
This paper describes a contrasting depositional model for blind tidal channel origin and development in the Skagit River delta. Chronological sequences of historical maps and photos spanning the last century show that as sediments accumulated
Ursachen und zeitliche Einordnung der Souris River Umlenkung in Südmanitoba (Kanada). in Wasserhaushalt und Gewässer. Festschrift zum 60. Geburtstag von Professor Dr. Reiner Keller.. (Causes and datation of the Souris River diversion in southern
The Souris River in southern Manitoba is well known as a river which shows a very sharp elbow in its course between the source south-east of Regina (Saskatchewan) and the mouth near Treesbank in Manitoba. There have been only three publications so
Sediment characteristics at river confluences : a case study of the Mula-Kas confluence, Maharashtra, India
mouth suggests that there have been instances in the past where the mainstream flow has dominated the confluence and has led to slack water deposits on the tributary mouth. In this large seasonal river, confluence sedimentology is a joint product of flow
This paper examines sediment transfer processes at river junctions, using as a case study the River Kas, a tributary of the River Mula, Godavari basin, Maharashtra. The study uses 4 cross-sections, 2 from upstream tributaries, one in the main
