Rainfall Characteristics of the Liudaogou Catchment on the Northern Loess Plateau of China
The objectives of this study were to understand the rainfall characteristics of thewind-water erosion crisscross region on the northern Loess Plateau, China, to provide basisfor the studies on mitigation of soil erosion, estimation on surface water resources andlocal hydrological circle, etc. The Liudaogou Catchment with representative climatic andhydrologic conditions of wind-water erosion cri...
متن کاملStatistical Determination of Rainfall-Runoff Erosivity Indices for Single Storms in the Chinese Loess Plateau
Correlation analysis is popular in erosion- or earth-related studies, however, few studies compare correlations on a basis of statistical testing, which should be conducted to determine the statistical significance of the observed sample difference. This study aims to statistically determine the erosivity index of single storms, which requires comparison of a large number of dependent correlati...
متن کاملProjected changes in US rainfall erosivity
Downscaled rainfall projections from 21 climate models from the CMIP5 (Coupled Model Intercomparison Project Phase 5) archive are used to estimate future changes in rainfall erosivity in the continental Unites States. To estimate erosivity from rainfall in the absence of sub-hourly data, we have used both daily rainfall values and the modified Fournier index – which is based on monthly rainfall...
متن کاملSustainable Fertilizer Level for Winter Wheat in Different Rainfall Regions on the Loess Plateau of China
Higher fertilization on winter wheat increased the fluctuation of winter wheat yield in different rainfall years and impacted the sustainable development of winter wheat production on the Loess Plateau. Based on the long term field experimental data at Chagnwu Agricultural Station, this paper evaluated the EPIC model. And this paper also suggested a sustainable fertilizer level for winter wheat...
متن کاملRainfall erosivity in Europe.
Rainfall is one the main drivers of soil erosion. The erosive force of rainfall is expressed as rainfall erosivity. Rainfall erosivity considers the rainfall amount and intensity, and is most commonly expressed as the R-factor in the USLE model and its revised version, RUSLE. At national and continental levels, the scarce availability of data obliges soil erosion modellers to estimate this fact...
