TL;DR: In this article, the authors explored discrepancies between the predictive performance of a landslide susceptibility model and the geomorphic plausibility of subsequent landslide susceptibility maps while a particular emphasis was placed on the influence of incomplete landslide inventories on modelling and validation results.

TL;DR: In this paper, a statistical approach was employed to model the spatial distribution of rainfall-triggered landslides in two areas in Sicily (Italy) that occurred during the winter of 2004-2005.

TL;DR: In this paper, three SfM-based photogrammetric experiments were conducted on the embayed beach of Montjoly in Cayenne, French Guiana, between October 2013 and 2014, in order to map morphological changes and quantify sediment budgets.

TL;DR: In this paper, a 125,000 m2 calanchi badland in the Province of Siena (Tuscany) was monitored with an unmanned aerial vehicle (UAV) and terrestrial laser scanning over the period of one year.

TL;DR: In this article, the authors investigated the lateral and vertical heterogeneity in bank material properties and riparian vegetation within two elongate meander loops on a large mixed bedrock-alluvial river using several geotechnical field and laboratory methods.

TL;DR: In this article, the authors investigated the geomorphic response of mountain rivers to extreme floods, exploring the relationships between morphological changes and controlling factors such as lateral confinement and hydraulic variables.

TL;DR: In this article, the authors used the revised Universal Soil Loss Equation (RUSLE) to estimate the annual soil erosion rates on hillslopes and compared them with Cs-137 budget in the depressions at two typical karst peak-cluster depression basins in northwest Guangxi, southwestern China.

TL;DR: In this paper, the authors analyzed the largest data set of subglacial bedform size and shape measurements and found that flutes form a distinct population of narrow bedforms and a continuum of sub-glacial ribs also exists, with no clear size or shape distinctions indicating separate populations.

TL;DR: This article explored the local intensity-duration (I-D) relationship based on 252 post-earthquake debris flows and found that I = 525 D-0.76 accounts for more than 98% of the debris flow occurrences with rainfall duration between 1 and 135 h.

TL;DR: In this article, the authors explore some of the issues associated with the conceptualisation and modelling of coastal morphological change at time and space scales relevant to managers and policy makers and explore the limitations of a primary scale approach and the extent to which these can be resolved with reference to the concept of the coastal tract and application of systems theory.

TL;DR: In this paper, the authors investigate the transportation rate of splash load (SL) and that of wash load (WL) and their relative contributions to the rain-induced erosion rate affected by rain intensity, slope gradient and particle size distribution.

TL;DR: In this article, historical changes in the extent of the stream channel network and in channel planform within the upper Sangamon River basin have been studied, showing that humans are effective agents of morphological change in fluvial systems.

TL;DR: The Oso, Washington, USA, landslide occurred on the morning of Saturday, 22 March 2014 and claimed the lives of 43 people as mentioned in this paper, and the landslide began within an ~200m-high hillslope comprised of unconsolidated glacial and previous landslide/colluvial deposits; it continued as a debris avalanche/debris flow that rapidly inundated a neighborhood of 35 single-family residences.

TL;DR: In this article, the authors identify the immediate eco-geomorphic responses to removal of a run-of-river industrial dam on Amethyst Brook (26 km2) in central Massachusetts.

TL;DR: In this paper, the authors developed new pedotransfer functions to estimate the soil erodibility (K) using multiple linear regression, Mamdani fuzzy inference systems, and artificial neural networks.

TL;DR: In this paper, a localized contour tree method was proposed for automated sinkhole extraction in karst landscapes, and the results suggest that previous visual interpretation method might significantly underestimate the number of potential sinkholes in the region.

TL;DR: In this article, the influence of the junction angle and discharge ratio on flow dynamics and bed morphology of mountain river confluences was examined, and it was shown that the discharge ratio and junction angle parameters are major controls of the dynamics of the mountain confluence.

TL;DR: In this paper, the authors focus on the coupled economic and physical dynamics of developed shorelines, and identify salient individual and social behaviors of decision-making in ways that capture societal actions across a range of scales (thus engaging economics, social science, and policy disciplines).

TL;DR: In the UK, a series of deep Atlantic low pressure systems crossed the Northeast Atlantic, and strong winds, high waves and high water levels affected many coastal areas in the UK and other parts of western Europe.

TL;DR: In this paper, the effects of continuous inflow perturbation and bar-floodplain conversion on meander migration were investigated using three numerical morphodynamic models: a 1D-model, and two 2D-models with one of them using adaptive moving grid.
