Few studies have considered downstream changes in bank erosion rates and variability along single river systems. This paper reports some preliminary results of an intensive direct field monitoring exercise on 11 sites 130 km the 3315 km2 Swale-Ouse system northern England over a 14·5 month period. Data were collected at active using grid networks pins read c. 18–30 day intervals bank-line resurveys. Erosion relatively high for this scale: spatially averaged magnitudes months varied from 82·7...
This paper evaluates the relationships between atmospheric circulation, climate and streamflow in northern North Atlantic region over last century especially 50 years. Improved understanding of climatic influences on is vital given great importance fluvial processes to natural systems water resources, light recent predicted change. The main focus lies with hydrologic implications major circulation patterns Atlantic, namely Oscillation (NAO) Arctic (AO). studies reviewed here reveal key...
River bank retreat around two meander bends in South Wales was monitored over a two-year period with dense grid-networks of erosion pins. Results show that strong seasonality river occurs, almost all taking place the winter months December, January and February. Catchment instrumentation field observations allowed this seasonal pattern to be interpreted respect range geomorphological, hydrological meteorological processes or indices. Frost action emerges as strongest control average maximum...
Abstract This study examines for the first time changing characteristics of summer and winter southern African rainfall their teleconnections with large‐scale climate through dominant scales variability. As determined by wavelet analysis, austral indices exhibit three significant variability over twentieth century: interdecadal (15–28 years), quasi‐decadal (8–13 interannual (2–8 years). Teleconnections global sea surface temperature atmospheric circulation anomalies are established here but...
The rates and processes of erosion deposition soils sediments are subjects widespread increasing concern in the Earth environmental sciences. Process inference from field studies, however, has been hampered by a lack information on precise magnitude, frequency timing erosional depositional activity, because no automatic monitoring technique hitherto available. I describe here an Photo‐Electronic Erosion Pin (PEEP) system which, apparently for first time, allows quasi‐continuous time series...
Abstract. This paper examines river bank retreat rates, individual erosion events, and the processes that drive them in Upper Severn basin, mid-Wales, UK. Traditional pin networks were used to deliver information on patterns of downstream change rates. In addition, novel automatic Photo-Electronic Erosion Pin (PEEP) monitoring system was deployed generate near-continuous data temporal distribution accretion: this allowed focus magnitude timing erosional depositional events relation specific...
Concerns about recent river flow changes are increasing, given their importance for water management, flooding, drought mitigation, and geomorphological ecological processes. For the first time, this paper develops a full picture of streamflow trends over period 1962–2001 western Britain across entire spectrum, at annual seasonal resolutions, 56 gauging stations three study periods. Annual calculated mapped using non‐parametric Mann‐Kendall test with bootstrap resampling. Several...
Abstract Stream power can be an extremely useful index of fluvial sediment transport, channel pattern, river erosion and riparian habitat development. However, most previous studies downstream changes in stream have relied on field measurements at selected cross‐sections, which are time consuming, typically based limited data, cannot fully represent important spatial variations power. We present here, therefore, a novel methodology we call CAFES (combined automated flood, elevation power),...
Abstract This paper investigates the dynamics and significance of discharge suspended sediment transport (SST) during two jökulhlaups (glacier outburst floods) in Skaftá River, south Iceland. Jökulhlaups occur frequently many glacial environments are highly significant geomorphological evolution river basins coastal environments. However, direct high‐resolution monitoring has rarely been accomplished hardly ever at more than one station a downstream sequence. Here we present detailed data on...
Correlation of monthly inter‐regional river flow and composite analysis large‐scale climatic patterns associated with high low regional are presented for the northern North Atlantic domain 1968–1997. Hydrological regions defined using cluster analysis. Adjacent hydrological generally display year‐round positive correlation flow. For first time, inverse relationships identified between America Europe in autumn, southern from April–May July–December. Composite shows linkages European Icelandic...
