losses; 4) slope irregularities created by long term erosion allow runoff to infiltrate locally; 5) vegetative strips hamper rill and gully formation; 6) erosion mainly results from infrequent high intensity rainfall events, and 7) upscaling of experimental results leads to overestimation of erosion....
For the full and better simulation of the erosive landslide, we must numerically integrate (12) together with (1) that includes evolution of both the flow velocity and the flow depth. This will be discussed later. Here, we are mainly interested in developing a simple model that can be solve...
The results showed that the average soil loss is 1.98×10~3 t km~(-2) a~(-1). There are different levels of soil erosion in about 40% of the area. Serious erosion mainly comes from elven catchments(M4—M7, M9, T4—T6, T8, T10, and T20). Land cover type, slope, and ...
The test results reveal that internal erosion would cause the increase of hydraulic conductivity and volumetric deformation of the tested specimens. Internal erosion would mainly induce the reduction of the drained compressive strength. The undrained peak deviator stress of the soil that suffered from ...
The last segment was a 5-km long subreach, i.e., from RK 560 to RK 565. The error of the estimated results is mainly from navigational charts data and the interpolation, which was estimated to be less than 10%29,30. Multi-beam data Riverbed bedforms along the main navigation channel...
3c). Runoff observations (n = 53) show a similar distribution, from which 28% corresponded to the first post-fire monitored year and decrease to 2% in the seventh year. The different post-fire mitigation treatments were mainly applied, as reflected in the higher number of observations, in ...
In rill erosion, sediment discharge mainly originated from the toe-slope and moved upwards as erosion intensified. The results obtained from this study suggest that multi-REE tracer technique is valuable in understanding the erosion processes and determining sediment sources. 展开 关键词: Soil erosion...
(3) The spatial variations of NPS pollution are closely related to spatial characteristics of rainfall, topography, and soil and land use types; the peak regions of TN and TP loss mainly occurred along the main river banks of the Yanhe River watershed from northeast to southeast, and gradually...
(Table1). Yet, further analysis of the spatiotemporal erosion patterns reveals that this difference of up to ±1.6 mm a−1results from dynamical reorganization during the asynchronous build-up of the EIS to its LGM extent (Fig.5c). The shifting eastward extent from 23-19 ka BP in ...
However, this flux is mainly directed into the CAA, the Nordic Seas, and the Labrador Seas from where they flow southward and not northward into the Arctic Ocean. Atmospheric deposition of nitrogen is estimated at approximately 0.1 Tg N yr−1 over the Arctic Ocean area without perennial sea...
