Rainfall, runoff and sediment transport relations in a mesoscale mountainous catchment: The River Isábena (Ebro basin)

Impact of urbanization on the sediment yield in tropical watershed using temporal land-use changes and a GIS-based model

“…The result shows that the amount of sediment yield in a watershed was directly proportional to the amount or intensity of the rainfall. Our findings was similar to the result illustrated by OLD et al [2003] and LÓPEZ-TARAZÓN et al [2010], that the amount of sediment produced in a watershed increases during high storm events. Figure 9 shows the relationship between sediment yields in an increase urbanization under varying rainfall conditions.…”

Suspended sediment behavior in a coastal dry-summer subtropical catchment: Effects of hydrologic preconditions

“…Previous studies have shown that precipitation-driven storm flows often display dramatically different suspended sediment behavior in comparison to flows attributed to interflow, ground water discharge, or recharge-oriented dam releases (winter recessional or summer base flow), due primarily to the increased contribution of hillslope and channel margin sediment from precipitation events (Lana-Renault et al, 2007;López-Tarazón et al, 2010;Oeurng et al, 2010;Tena et al, 2011;Gao and Josefson, 2012). Lack of sensitivity in the lower Salinas further supports the idea that the channel plays a significant role in moderating In-channel storage has been found to play a significant role in fine sediment dynamics in other rivers, with fine sediment content of 0.04-8.0 g/cm 2 reported for a wide range of rivers using a method that involved the agitation of the top 5-10 cm of bed material (Lambert and Walling, 1988;Walling and Quine, 1993;Droppo and Stone, 1994;Walling et al, 1998.…”

Continuous Monitoring of Suspended Sediment Load in Semi-arid Environments

“…Thirty-four flood were monitored using a turbidity probe and different hydrological and sedimentary responses of the cachment to similar rainfall were observed. This variability can be attributed to the sediment availability and to the antecedent soil moisture conditions (López-Tarazón et al, 2010). In the Eshtemoa basin (Israel) vegetation is sparse, small areas are cultivated for growing winter wheat and the steeper hillslopes are used for grazing.…”

“…This can be referred to the sediment depletion from hillslopes that influenced the last events. The relationship between the maximum SSC and Q p at event scale was evaluated considering the experimental values of the Carapelle torrent and those reported by Alexandrov et al (2003), Benkhaled & Remini (2003), Megnounif et al (2007) and López-Tarazón et al (2010) in order to determine a possible trend of the suspended sediment transport in semi-arid zones. A general trend exists between the SSC max and Q p ( fig.…”
