TL;DR: In this article, the authors present results of recent research in which digital elevation models (DEMs) have been developed for a reach of a large braided gravel-bed river in Scotland using both digital photogrammetry and high-resolution RTK GPS ground surveys.

TL;DR: In this paper, a conceptual framework is developed in which several types and degrees of connectivity are proposed, and it is hypothesised that sediment connectivity varies with sediment sources and with stream competence to transport the coarse fractions.

TL;DR: In this article, the authors identified ten types of wood debris accumulations in the Queets river basin and classified them based on the mode of recruitment and the orientation of key, racked, and loose debris relative to the channel axis.

TL;DR: In this article, a general morphometric analysis over 17 different mountain fronts was performed to evaluate the tectonic activity of SE Spain through the application of general morphometrical analysis.

TL;DR: In this article, self-accelerating rock fracture has been used to predict catastrophic and deep-seated slope collapse with loads similar to 1-10 MPa and readily catalysed by circulating fluids.

TL;DR: In this article, a series of spatially explicit equations are derived that form the foundation of a modeling framework that provides insight into how the interaction of the fetch effect and angle of wind approach leads to tradeoffs that govern the magnitude of aeolian sediment transport across beaches of different geometry.

TL;DR: The facies distribution in the sedimentary units infilling a series of Neogene basins has been used to reconstruct the relief generation and uplift across the Internal Zone of the Betic Cordillera in southern Spain this article.

TL;DR: In this paper, the authors measured the Darcy-Weisbach flow resistance in 20 step-pool channels with large woody debris (LWD) in Washington, and found that wood in step risers influences channel hydraulics more than wood elsewhere in the channel.

TL;DR: In this paper, an empirical calibration of the shear stress model for bedrock incision is presented, using field and hydrologic data from a series of small, coastal drainage basins near the Mendocino triple junction in northern California.

TL;DR: In this article, the influence of hydrological connections on the potential exchange of dissolved organic carbon between a large Australian floodplain to a river channel, and the effects of land and water developments on these exchanges are examined.

TL;DR: In this paper, stream-gradient and hypsometric analysis has been carried out to highlight the along-strike variations of morphotectonic features and to illustrate the relative activities in different tectonic regimes of the Western Foothills.

TL;DR: In this article, an interpretation of soil hydrology and erosion data obtained from limestone areas in southeast Spain is presented in the framework of recent hypotheses on runoff generation mechanisms in Mediterranean environments.

TL;DR: In 2000, a super-large landslide (3 x 10(8) m(3)) occurred along Zhamu Creek, southeast Tibet, and a landslide dam formed and the Yigong River was blocked.

TL;DR: In this paper, the authors estimate the contribution of landslides not detectable from aerial photographs to the global mass of sediment production from mass failures on forested terrain of the Capilano basin, coastal British Columbia.

TL;DR: In this paper, the authors proposed a method that incorporates antecedent rainfall and streamflow data to develop a landslide initiation threshold for the North Shore Mountains of Vancouver, British Columbia.

TL;DR: In this article, the authors evaluated the potential of 1-m resolution, 128-band hyperspectral imagery for mapping in-stream habitats, depths, and woody debris in third- to fifth-order streams in the northern Yellowstone region.

TL;DR: In this article, an image-processing method to map and monitor landslide activity using multitemporal optical imagery is proposed, which entails automatic change detection of suitably pre-processed (geometrically registered and radiometric normalised) sequential images, followed by thresholding into landslide-related change pixels.

TL;DR: Salas et al. as mentioned in this paper developed a factorial scoring index model that provides a fairly accurate and reliable prediction of area-specific sediment yield (SSY) for 60 catchments in Spain that was retrieved from sediment deposition rates in reservoirs.

TL;DR: In this article, a paired catchment analysis is performed between two moderate-sized sand-bed rivers in East Gippsland, Australia, to understand the evolution of these rivers in a long-term evolutionary context.

TL;DR: In this paper, the evolution of the Tessina landslide near Belluno, Italy, from 1954 to the present situation has been documented using multitemporal landslide maps using sequential aerial photographs and direct field-mapping of the landslide in 1998 and 1999.

TL;DR: In this paper, the authors compared two nearly adjacent reaches of third-order Mack Creek over the period 1978-1997 after virtually all wood was removed from the channel of the lower reach in 1964.

TL;DR: In this article, a study of the sediment budget for the Waipaoa catchment, North Island, New Zealand, included evaluation of long-term rates of landsliding for six landslide-prone land systems in the catchment.

TL;DR: In this article, a comparison of historic channel migration rates, modern planform conditions, and overall sediment, wood, and flow conditions and interactions for the Quinault River and Queets River in the western Olympic Peninsula, Washington, reveals decadal to century-scale interactions between gravel-bed channels and forested flood plains in temperate maritime environments.

TL;DR: In this article, the spatial patterns of sediment storage types and associated volumes using a novel approach for quantifying valley fill deposits are presented for a small alpine catchment (17 km 2 ) in the Bavarian Alps.

TL;DR: In this article, a process-based slope stability model was proposed to assess the effects of past and future land-use change on slope stability in the Ecuadorian Andes watershed.

TL;DR: The authors examined the effect of woody debris on patterns of sediment deposition within a small area of forest flood plain along the Highland Water, S. England, and found that the amount of overbank sediment deposition was correlated most closely with flood hydrology and sediment input.

TL;DR: In this paper, the authors studied a total of 43 Quaternary alluvial fans in the Granada and Bajo Segura basins (Betic Cordillera, Spain) and revealed the existence of distinct stratal stacking patterns, which is the result of differences in eustasy and tectonics.

TL;DR: In this paper, a 3D morphological adjustment in a chute cutoff (breach) alluvial channel is quantified using Digital Elevation Model (DEM) analysis for a ca. 0.7 km reach of the River Coquet, Northumberland, UK.

TL;DR: In this paper, a quasi-three-dimensional model using Lagrangian finite element method (LFEM) is formulated to reproduce the dynamic runout process caused by landslides.
