“…Suspended sediment yield is expected to decrease because of a reduction in streamflow and rainfall-major factors controlling sediment transport capacity. These results are consistent with those observed by Mukundan et al [67], Zabaleta et al [13] and Serpa et al [16], among others; these The increase in erosion rates in cultivated land-the dominant sediment source in the study area [37]-could be due, as was found in other studies (e.g., [11]), to the reduction of plant biomass, which was forecast to fall between 7% and 33%, depending on the temperature scenarios used [14]. Erosion is affected by the canopy of vegetation (which reduces the impact of rainfall energy), by crop residues (which protect the soil from the impact of raindrops and drastically reduce the rate of soil particle detachment and sediment transport capacity), and by plant roots and decomposing litter, which mechanically fix the soil in place and provide a medium for microorganisms to thrive.…”

“…In the other seasons, the sediment yield decrease is associated with a reduced streamflow. Mukundan et al [67] using the SWAT model to analyze the effect of climate change on soil erosion and sediment yield in the US, attributed the decrease in soil erosion in summer to the advance of the growing season, because this phenological change affects the quantity of crop residue and the length of time that it remains in the soil and, therefore, soil erosion. In the study catchment, a plant biomass increase in cultivated areas was observed during spring, possibly related to the onset of the growing season for maize.…”

Soil losses and the subsequent sediment delivery constitute significant environmental threats. Climate change is likely to have an impact on the availability of water and therefore on sediment yield in catchments. In this context, quantifying the sediment response to an increased atmospheric CO 2 concentration and climate change is of utmost importance to the proper management of rural catchments. However, quantitative assessment of climate change impact remains a complex task. In this study, the potential medium (2031-2060) and long-term (2069-2098) impacts of projected changes of temperature, rainfall and CO 2 concentration on sediment yield in a small rural catchment located in NW Spain were evaluated using the Soil and Water Assessment Tool (SWAT) model. Climate change scenarios were created using future climate data projected by regional climate models from the ENSEMBLES project and two CO 2 concentration scenarios (550 and 660 ppm). The results showed that climate change would have a noticeable impact on suspended sediment if the forecast temperature, rainfall and CO 2 concentration changes included in this study were met. Overall, suspended sediment is expected to decrease (2031-2060: −11%, 2069-2098: −8%) compared to the baseline period , mainly due to decreased streamflow. However, an increase in sediment transport in winter is predicted, possibly associated with increased erosion in cultivated areas (11%-17%), suggesting that, at this time of the year, the effect of soil detachment prevails over sediment transport capacity. Consequently, management practices aimed at reducing soil erosion in cultivated areas should be carried out, because these are the main source of sediment in the study area.

“…The siltation of reservoirs will decrease life expectacy and creates economic burders (Brosisnsky et al, 2015). Quantifying sediment yield is essential for many purposes (Yeshaneh et al, 2014), for example it can be used to understanding and predicting future sediment transport for watershed management planning (Mukundan et al, 2013). In addition, it can be used to design erosion control structures (Senti et al, 2001) and also to predict life expectancy of a reservoir (Ranzi et al, 2012).…”

:Quantifying sediment is essential to determine its sources and reduce its negative impacts. A study was conducted to quantify suspended sediments of catchments covering by teak plantation and to provide alternatives soil conservation practices. Five catchments with old teak coverages of 82, 82, 74, 70, and 53 % were chosen. At the outlet of each catchment was installed tide gauge to monitor stream water level (SWL). Water samples for sediment analyses were taken for every increament of SWL. Sediment yield was calculated based on rating curves of sediment discharge. The results showed that the sources of sediment in the streams were dryland agricultural and streambank erosion. The mean annual sediment yield during the study were 9.3, 10, 15, 53.3, and 22.5 t/ha for catchments covered by old teak plantation of 82, 82, 74, 70, and 53 %, respectively. To reduce sediment yield some soil conservation practices must be applied. Conservation of soil organic matter is important in order to stabilize soil aggregate and prevent clay dispersion which causes erosion and sedimentation. Green firebreaks or making channels are needed to prevent fire during dry season and organic matter loss. Stabilization of streambank is neccesary, either using vegetative method or civil technics.
