TL;DR: In this article, the authors focus on experimental research on rill and interrill erosion using simulated rainfall and recently developed techniques that provide data at appropriate temporal and spatial scales, essential for event-based soil erosion prediction.

TL;DR: In this paper, the authors investigated the role of matric suction, positive pore-water pressure and confining pressure for layered streambanks composed of cohesive materials in determining bank strength.

TL;DR: Beach ridges as mentioned in this paper are defined as relict, semiparallel, multiple wave- and wind-built landforms that originated in the inter- and supratidal zones.

TL;DR: This article reviewed the evidence and history of glacier fluctuations during the Little Ice Age (LIA) in the Canadian Rockies and concluded that the use of the term LIA should be restricted to describing a period of extended glacier cover rather than being used to define a period with specific climate conditions.

TL;DR: The role of breaking waves in shore platform development has been investigated on Kaikoura Peninsula by direct measurement of waves in deep water and on platforms at high tide in this article.

TL;DR: In this paper, the authors analyzed channel planform change using a variety of data-sources for the medium-term (>25 years) and the long-term (over 25 years).

TL;DR: In this article, the fluvial evolution of several rivers in northern and central Europe during the Last Glaciation was discussed in more detail, and it appeared that grain size, basin configuration and catchment size are important parameters also, which can determine whether a threshold is exceeded or not.

TL;DR: In this paper, an inventory of about 400 individual rock glacier sites in West Greenland was carried out by means of field studies, and using aerial photographs and topographic maps, to obtain knowledge on rockwall retreat rates at sites with rock glaciers.

TL;DR: In this article, the same age is proposed for the beginning of the main incision in the Somme Valley on the basis of morphostratigraphy, pedostratigraphemy, palaeontology, and palaeomagnetism.

TL;DR: In this paper, the efficiency of five aeolian sand samplers was tested via wind tunnel experiments and field measurements, and the most recommendable sampler in the test is the MWAC, not only because of its high efficiency, but also because its efficiency is independent of wind speed.

TL;DR: The role of subaerial weathering in the development of shore platforms on Kaikoura Peninsula is investigated in this article, where Schmidt Hammer test data showed that weathering had occurred and that rock strength was reduced through weathering by as much as 50%.

TL;DR: In this article, an agricultural drainage basin of 250 ha was selected in the Belgian Loam Belt to evaluate sediment export by water and water discharge was continuously measured at the outlet of the catchment and suspended sediment samples were taken proportional with discharge during rainfall events.

TL;DR: In this article, the authors presented detailed shape measurements of several barchan dunes in southern Morocco, near Laâyoune, using these data to disprove the concept of shape invariance of dunes of different sizes.

TL;DR: In this paper, a morphologic classification of Laurentide eskers is proposed, and five types of eskers are identified and investigated: type I eskers likely formed in extensive, synchronous, dendritic R-channel networks under regionally stagnant ice.

TL;DR: In this article, the authors examined the incision achieved during the Quaternary by the Thames, in both its upper and lower catchments, and by the Hampshire Avon in southern England.

TL;DR: In this article, wood storage within the active zone of the dynamic, gravel-bed, Fiume Tagliamento, Italy, was investigated at eight sites along the river's main stem.

TL;DR: In this paper, the authors investigated the morphology of bank gullies, i.e., geometrical characteristics resulting from past erosion and active erosion processes shaping the gully, and found relationships with environmental site characteristics, such as topographical parameters, material properties and climate.

TL;DR: In this article, a flood event occurred on 30 September 1997, in three catchments, Torrealvilla, Salada and Nogalte, in SE Spain which were being monitored for morphological change.

TL;DR: In this paper, the authors studied the downstream changes along the Sandover, Bundey (Sandover-Bundey) and Woodforde (Woodforde) rivers on the Northern Plains of arid central Australia.

TL;DR: In this article, the authors used velocity fluctuations in a space-time matrix that allows one to see the structures as they pass an array of current meters and found that the average angle of the front of the wedges is 36° and the average frequency is nine events per minute and their duration is more than 2 s.

TL;DR: In this article, the authors used the highest slackwater deposits and flood indicators from the tributary mouths, low river terraces, and the loess platforms and loess alcoves, together with radiocarbon dating, provided evidence of at least six floods with peak discharges greater than 27,300 m3 s−1 at Xiaolangdi Section over the last 8500 yr.

TL;DR: In this paper, the authors trace the detailed network evolution in the most sensitive areas by reconstructing former drainage pathways using abandoned drainage cols and the alignment and degree of incision of the drainage networks.

TL;DR: In this article, erosion and deposition patterns within two agricultural catchments in the Belgian Loam Belt were mapped and their volumes measured after an intense rainfall event, and the total erosion and sediment budget was calculated.

TL;DR: In this paper, three representative weathering profiles developed on the hilltops indicate that sand represents more than 50% by weight throughout most of the weathering profile, and silt-and clay-size fractions are also well represented, filling the interstices among corestones.

TL;DR: A planation surface was created at the end of Lower Pliocene from the Costa to the Oriente graded to sea level by uplift of the Cordillera as mentioned in this paper.

TL;DR: In this paper, a linear diffusion equation for slow, quasi-continuous mass movement (e.g., creep), which is based on a large data compilation, is adopted in the hillslope model.

TL;DR: An automatic bedload monitoring station has been established on the perennial Tordera River, a Mediterranean mountain gravel-bed stream located in NE Spain, where two Birkbeck-type pit bedload samplers aligned across the width of the channel were used as mentioned in this paper.

TL;DR: In this paper, slope and stream power changes in the Lower Mississippi River during the pre-cutoff (1880s-1930s), and post-cut off (1943-1992) periods were studied.

TL;DR: In this paper, the Hallamish dune field in the western Negev Desert, Israel, was studied and the differences in crust type could not have been attributed to rainfall, dewfall, temperatures, or eolian input.
