TLDR
The applicability of such results to conditions of natural rainfall has been thrown in doubt as discussed by the authors, and the results have been found to be affected by the drop-size and velocity of the artificial rains applied.Abstract:
Curiosity concerning the drop-size composition of natural rain has arisen from attempts to measure erodibility and infiltration-capacity by sprinkling small areas of land with artificial rain. The results have been found to be affected by the drop-size and velocity of the artificial rains applied, and the applicability of such results to conditions of natural rainfall has been thrown in doubt.read more

Physics of liquid jets
Jens Eggers,Emmanuel Villermaux +1 more
TL;DR: A review of the fundamental and technological aspects of these subjects can be found in this article, where the focus is mainly on surface tension effects, which result from the cohesive properties of liquids Paradoxically, cohesive forces promote the breakup of jets, widely encountered in nature, technology and basic science.

Aggregate stability and assessment of soil crustability and erodibility: I. Theory and methodology
TL;DR: In this paper, a unified framework for the measurement of aggregate stability is proposed to assess a soil's susceptibility to crusting and erosion, which combines three treatments having various wetting conditions and energies (fast wetting, slow wetting and stirring after pre-wetting).

TL;DR: The European Soil Erosion Model (EUROSEM) as mentioned in this paper is a dynamic distributed model able to simulate sediment transport, erosion and deposition over the land surface by rill and interill processes in single storms for both individual fields and small catchments.

Rainfall energy and its relationship to soil loss
W. H. Wischmeier,Dwight D. Smith +1 more
TL;DR: In this article, a relatively simple procedure is presented for computation of kinetic energy of a rainstorm from information on a recording-raingage chart, and an equation is developed describing rainfall energy as a function of rainfall intensity.

Measurements of the fall-velocity of water -drops and raindrops
Abstract: This paper presents measurements of the velocities of water-drops of sizes ranging from one to six mm in diameter, falling in still air from heights of 0.5 meter to 20 meters. A few measurements of raindrop velocities are also reported.
The measurements were undertaken to assist in an understanding of the action of rain, both real and artificial, in eroding soil. The drop-sizes of rains have also been measured and will be reported separately. All of these studies were carried out at the Hydraulic Laboratory of the National Bureau of Standards as a part of the work of the Soil Conservation Service.
