“…Some similarities are observed with the spatial 437 distribution of 137 Cs-derived estimates from a gully catchment in the Loess Plateau 438 (China), which showed that soil erosion rates increase from the ridge tops and 439 interfluves to the lower slopes (Yang et al, 2006). However, although the magnitude of 440 erosion rates is comparable with that in the loess gully catchment, our highest rates for 441 both erosion and deposition are mostly related to the agricultural use of the low and flat 442…”

15Caesium-137 derived from nuclear testing in the past century has been widely used as a 16 sediment tracer of soil redistribution, providing information on medium term (40-50 17 years) erosion rates. To date, most studies have focused on individual fields of limited 18 extent, but estimated rates and patterns of soil redistribution require upscaling to 19 catchment level. An attempt to assess soil redistribution processes with strong 20 geomorphic control on complex terrain, such as an internally drained karstic catchment, 21 is presented in this work. A comprehensive geomorphological survey of the Estanya 22 Lake catchment (Spanish Pyrenees) enabled the main geomorphic elements to be 23 identified with a grid resolution of 5 x 5 m, which was the basis for the terrain analyses.

“…Sorption equilibrium of 137 Cs or 90 Sr into soil samples was achieved after 5 days of contact with Kd was approximately about 3000-4200 mL/g. However, the result was little bit higher than other references due to the different experiment condition [14][15].…”

“…Based on common practice for check dam construction in the area, a new dam would be constructed when a check dam is filled with sediments to continue capturing sediment from the upstream reaches. A study in this area by Yang et al (2006) and Zhang et al (2006) indicated that most sediments are transported from the gully slopes or by gravity erosion. The 137 Cs content of the sediments is generally less than 1.0 Bq/kg and averages 0.67 Bq/kg.…”

“…As an example in the A0 cores, the clay content of six layers (250-290, 305-330, 330-350, 400-440, 460-400, and 530-550 cm) decreased with soil deposition depths, due to six rainfall events. Different thicknesses of sediment accumulation indicate the degree of rainfall erosion intensity Yang et al 2006). …”

Check dam sediments document the process of soil erosion for a watershed. The main objectives of this research are as follows: first, to determine whether the sediments trapped in check dams can provide useful information about local erosion and the environment, and second, to obtain the extent to which they can be stratigraphically interpreted and correlated to the land use history of an area controlled by check dams. Particle size and the concentration of 137 Cs in sediments are the indicators used to study the effects of environmental changes on soil erosion in the Loess Plateau, China. A total of 216 soil samples were collected from four sediment profile cores at the Yangjuangou watershed check dam constructed in 1955 and fully silted with sediments by 1965. The results indicated that 137 Cs dating and sediment particle size can characterize the sediment deposition process. Silt makes up more than 50 % of the sediment; both the clay and silt sediment fractions decrease gradually in the upstream direction. The sediment profiles are characterized by three depositional layers. These layers suggest changes in the land use. The top layer showed tillage disturbance, with moderate sediments and new soil mixed from 0 to 20 cm. A transition stage from wetlands (characterized by vegetation such as bulrush) to cropland is inferred from sediments at depths of 20-85 cm. Below 85 cm, sedimentary layering is obvious and there is no tillage disturbance. At the downstream site, A0, the average rate of sediment deposition from 1958 to 1963 was approximately 6,125.4 t year −1 km −2 . Because of their high time resolution, check dam sediments indicate the effects of environmental changes on soil erosion, and they can provide a multiyear record of the soil erosion evolution at the local scale in the middle reaches of the Yellow River.
