Robert E. Hortons perceptual model of infiltration processes - Beven - 2004 - Hydrological Processes
Robert E. Horton is best known as the originator of the infiltration excess overland flow concept for storm hydrograph analysis and prediction, which, in conjunction with the unit hydrograph concept, provided the foundation for engineering hydrology for several decades. Although these concepts, at least in their simplest form, have been largely superseded, a study of Horton's archived scientific ... read more >>

There is a peculiar thing that happens to the Sahara. Periodically, it turns into a green Savanna. This happens when it gets more heat input. Yes, more.
With a little more heat (not necessarily just as temperature) there is an influx of rain. More rain falls, and plants start to grow. This growth puts even more water into the air via transpiration. This causes more rain, leading to more growt ... read more >>
Changes in solar activity have contributed no more than 10 percent to global warming in the twentieth century, a new study has found. The findings, made by Professor Terry Sloan at the University of Lancaster and Professor Sir Arnold Wolfendale at the University of Durham, find that neither changes in the activity of the Sun, nor its impact in blocking cosmic rays, can be a significant contributo ... read more >>
