Erosion, transport and deposition of a sediment replenishment under flood conditionsEarth Surface Processes and Landforms - Tập 45 Số 13 - Trang 3354-3367 - 2020

AbstractRiver reaches downstream of dams with constant residual discharge often lack sediment supply and periodic high flows due to dam sediment retention and flow regulation, respectively. To test a novel multi‐deposit methodology for defining environmental flows for activating the dynamics of the river morphology downstream of dams, a flood was released from Ross...... hiện toàn bộ
Flood hydrology and geomorphic effectiveness in the central AppalachiansEarth Surface Processes and Landforms - Tập 15 Số 2 - Trang 119-134 - 1990
Andrew J. Miller
AbstractThis paper compares hydrologic records and geomorphic effects of several historic floods in the central Appalachian region of the eastern United States. The most recent of these, occurring in November 1985, was the largest ever recorded in West Virginia, with peak discharges exceeding the estimated 500‐year discharge at eight of eleven stations in the South...... hiện toàn bộ
Longitudinal distributions of river flood power: the combined automated flood, elevation and stream power (CAFES) methodologyEarth Surface Processes and Landforms - Tập 34 Số 2 - Trang 280-290 - 2009

AbstractStream power can be an extremely useful index of fluvial sediment transport, channel pattern, river channel erosion and riparian habitat development. However, most previous studies of downstream changes in stream power have relied on field measurements at selected cross‐sections, which are time consuming, and typically based on limited data, which cannot fu...... hiện toàn bộ
Development of ST:REAM: a reach‐based stream power balance approach for predicting alluvial river channel adjustmentEarth Surface Processes and Landforms - Tập 40 Số 3 - Trang 403-413 - 2015

AbstractRiver channel sediment dynamics are important in integrated catchment management because changes in channel morphology resulting from sediment transfer have important implications for many river functions. However, application of existing approaches that account for catchment‐scale sediment dynamics has been limited, largely due to the difficulty in obtaini...... hiện toàn bộ
Impact of reach geometry on stream channel sensitivity to extreme floodsEarth Surface Processes and Landforms - Tập 39 Số 13 - Trang 1778-1789 - 2014

ABSTRACTPredicting spatial and temporal variations in bank erosion due to extreme floods presents a long‐standing challenge in geomorphology. We develop two methodologies for rapid, regional‐scale assessments of stream reaches susceptible to channel widening. The first proposes that channel widening occurs when unit stream power exceeds a critical threshold (300 W/...... hiện toàn bộ
River channel and bar patterns explained and predicted by an empirical and a physics‐based methodEarth Surface Processes and Landforms - Tập 36 Số 6 - Trang 721-738 - 2011
Maarten G. Kleinhans, Jan H. van den Berg
AbstractOur objective is to understand general causes of different river channel patterns. In this paper we compare an empirical stream power‐based classification and a physics‐based bar pattern predictor. We present a careful selection of data from the literature that contains rivers with discharge and median bed particle size ranging over several orders of magnit...... hiện toàn bộ
Influence of rock mass strength on the erosion rate of alpine cliffsEarth Surface Processes and Landforms - Tập 34 Số 10 - Trang 1339-1352 - 2009

AbstractCollapse of cliff faces by rockfall is a primary mode of bedrock erosion in alpine environments and exerts a first‐order control on the morphologic development of these landscapes. In this work we investigate the influence of rock mass strength on the retreat rate of alpine cliffs. To quantify rockwall competence we employed the Slope Mass Rating (SMR) geom...... hiện toàn bộ
