| 1 | 黄土高原小区径流过程预测模型评价显示文摘地表径流是土壤侵蚀和泥沙搬运的主要原动力。径流过程及其特征值是侵蚀模型,特别是侵蚀过程模型中水文模块的重要输入资料,但相对于降雨过程和径流总量资料,径流过程数据十分匮乏。为了对径流过程进行有效模拟,本文利用黄河流域子洲径流试验站团山沟3个小区107场降雨-径流过程观测数据,在小区尺度上对比验证3个仅含有1个参数的简易入渗模型:Ⅰ入渗能力恒定法,即假设入渗能力为1个常值,产流仅发生在降雨强度大于此值的情况;Ⅱ径流系数法,即假设实际入渗率与降雨强度呈正比关系,比例系数为1与径流系数的差值;Ⅲ入渗能力空间变异法,即假设入渗能力存在空间差异,实际入渗率表现为最大入渗率和降雨强度的指数形式。同时,为考查模型在不同时间尺度上的表现,文章分别选取1、6和15 min对数据进行重采样。结果显示:以洪峰流量和有效流量的预测精度作为模型有效性评价指标,相较于径流系数法和入渗能力空间变异法,入渗能力恒定法对黄土高原区径流过程的模拟效果最好,即入渗能力恒定更符合于黄土区实际产流入渗特点;随着过程资料采样时间间隔的增加,模型的模拟精度显著提高,即模型并不依赖于高密度的采样数据。研究结果可为缺乏径流过程资料的地区提供径流过程的计算方法,且有助于定量描述水文过程、土壤侵蚀和泥沙搬运过程。 | 程卓 Bofu Yu 符素华 | 2016 | 中国水土保持科学2016，14，6： | 2 |

| 10 | MINErosion 4:Using measurements from a tilting flume-rainfall simulator facility to predict erosion rates from post-mining catchments/landscapes in Central Queensland,Australia显示文摘The use of draglines to remove overburden in Queensland opencut mines,results in landscapes that consist of long parallel tertiary overburden spoil-piles that are generally highly saline,dispersive,and highly erodible.The height of these spoil-piles may exceed 50-60 m above the original landscapes and the slopes are at the angle of repose of around 75%or 37°.Legislation and public opinion require that these highly disturbed open-cut post-mining landscapes should be satisfactorily rehabilitated into an approved post-mining land use with acceptable erosion rates.Therefore,these slopes must be reduced before the landscape can be rehabilitated.The most expensive component of the rehabilitation process is the re-shaping and preparation of the overburden to create a suitable landscape for vegetation growth.As soils and overburden varies greatly in their erodibilities,the extent and cost of earthworks can be minimized,and rehabilitation failures avoided,if soil erosion from designed landscapes can be predicted using laboratory-based parameters prior to construction of these landscapes.This paper describes the development of a model for that purpose.A catchment or landscape erosion model MINErosion 4 was developed by upscaling the existing hillslope model MINErosion 3(So,et al.,2018)and integrate it with both ESRI ArcGIS 10.3 or QGIS 3.16(freeware),to predict event based and mean annual erosion rate from a postmining catchment or landscape.MINErosion 3 is a model that can be used to predict event and annual erosion rates from field scale hillslopes using laboratory measured erodibility parameters or routinely measured soil physical and chemical properties,and to derive suitable landscape design parameters(slope gradient,slope length and vegetation cover)that will result in acceptable erosion rates.But it cannot be used to predict the sediment delivery from catchments or landscapes.MINErosion 4 was validated against data collected on three instrumented catchments(up to 0.91 ha in size)on the Curragh mine site in Central Queensland.The agreement between predicted(Y)and measured(x)values were very good with the regression equation of Y-0.92X and an R^(2) value of 0.81 for individual storm events,and Y-1.47X and an R^(2) value of 0.73 for the average annual soil loss.This is probably the first time that a catchment scale erosion is successfully predicted from laboratory measured erodibility parameters. | Ashraf MKhalifa Hwat Bing So Hossein Ghadiri Chris Carroll Peter Burger Bofu Yu | 2023 | International Soil and Water Conservation Research2023，11，3： | 0 |
