“…In this case, even if a digital elevation model with higher resolution was available, the resolution of the soil and geological characteristics, as well as of the land use map, suggested that any cell size smaller than 100 × 100 m was unreasonable. This, together with previous modelling studies ( Bussi et al, 2013Bussi et al, , 2014b justifies the mesh resolution used in this study.…”

“…Vélez et al, 2009;Andrés-Doménech et al, 2010;Cowpertwait et al, 2013;Salazar et al, 2013). In addition, previous applications were developed for a catchment located in the Eastern Pyrenean area (River Ésera, Bussi et al, 2014b), proving the applicability of the model for the region of study. The TETIS model is a spatiallydistributed model, and thus allows the reproduction of land-use variability in space.…”

“…However, this widely-used method is empirically-based. Recent progresses in developing models using physically-based equations to describe surface soil loss and sediment routing may improve sediment yield simulating results [28,40,41]. Besides, obtaining long-term hydrological measurements could help to refine the model evaluation processes.…”

Climate change is expected to have stronger effects on water resources in higher latitude regions. Despite intensive research on possible hydrological responses in those regions to a warmer environment, our knowledge on erosion and sediment yield induced by the climate change in high-latitude headwaters is still limited. In this study, we estimated suspended sediment yields from 2021 to 2050 in a typical headwater area of far Northeast China to elucidate potential impacts of future climate change on surface runoff and erosion in higher latitude regions. We first parameterized the Soil and Water Assessment Tool (SWAT) using historical measurements to estimate runoff from the river basin. The model performed well in both the calibration (2006)(2007)(2008)(2009)(2010)(2011) and the validation (2012-2014) periods, with an R 2 of 0.85 and 0.88 and a Nash-Sutcliffe Efficiency (NSE) of 0.7 and 0.73, respectively. We also utilized historical measurements on sediment yields from the period 2006-2014 to develop a runoff-sediment yield rating curve, and the rating curve obtained an excellent goodness of fit (R 2 = 0.91, p < 0.001). We then applied the calibrated SWAT model to two climate change projections, also known as Representative Concentration Pathways (RCP4.5 and RCP8.5), for the period from 2021 to 2050 to obtain future runoff estimates. These runoff estimates were then used to predict future sediment yield by using the developed runoff-sediment yield rating curve. Our study found a significant increase of annual sediment yield (p < 0.05) for both climate change projections (RCP4.5 = 237%; RCP8.5 = 133%) in this, China's high-latitude region. The increases of sediment yield were prevalent in summer and autumn, varying from 102-299% between the two RCPs scenarios. Precipitation was the dominated factor that determined the variation of runoff and sediment yield. A warming climate could bring more snowmelt-induced spring runoff and longer rainy days in autumn, hence leading to higher erosion. These findings demonstrate that under the changing climate, soils in this high-latitude headwater area would be eroded twice to three times that of the baseline period , indicating a potential risk to the downstream water quality and reservoir management.

“…Most of the studies have focused primarily on medium and large Mediterranean basins in which soil erosion gives rise to serious problems [11,16,17]. It might be expected that sediment yield would decrease with streamflow, although this does not always happen [18].…”

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.
