The Effects of Tropical Vegetation on Rainfall [PDF]

open access: yesAnnual Review of Environment and Resources, 2018
Vegetation modifies land-surface properties, mediating the exchange of energy, moisture, trace gases, and aerosols between the land and the atmosphere. These exchanges influence the atmosphere on local, regional, and global scales. Through altering surface properties, vegetation change can impact on weather and climate.

Effect of radar‐rainfall uncertainties on the spatial characterization of rainfall events [PDF]

open access: yesJournal of Geophysical Research: Atmospheres, 2010
Remotely sensed precipitation products, due to their large areal coverage and high resolution, have been widely used to provide information on the spatiotemporal structure of rainfall. However, it is well known that these precipitation products also suffer from large uncertainties that originate from various sources.

Effect of Texture, Rainfall and Slope on Rainfall Interrill Sediment Transport [PDF]

open access: yesHydrology Research, 1991
Experiments were conducted with rainfall intensities of 45.0 and 140.0 mm/hr at slopes of 2, 9 and 20 per cent to separate the dominant effect of rainfall intensity on sediment transport capacity. The effect of sediment size on rainintensity contribution to unit sediment transport capacity was also investigated.
