Climate‐induced changes in erosion during the 21st century for eight U.S. locations

摘要: [1] Climate in the United States is expected to change during 21st century, and soil erosion rates may be response changes climate for a variety of reasons. This study was undertaken investigate potential impacts on by water. Erosion at eight locations modeled using Water Prediction Project model modified account effects atmospheric CO2 concentrations plant growth. Simulated data from U.K. Meteorological Office's Hadley Centre HadCM3 Global Circulation Model were used. The results indicated complex set interactions between several factors that affect process. Direct rainfall increases decreases runoff observed but often not dominant. One key system biomass production. Changes moisture, concentration, temperature, solar radiation each impacted production differing levels different sites. Different types occurring periods year also complicated system. Overall, these suggest where precipitation are significant, can increase. Where occur, more due largely biomass, runoff, erosion, either or overall expected.
