RUNOFF AND SEDIMENT TRANSPORT CHARACTERISTICS ON THE CHATCH MENT SCALE

Transforms for Runoff and Sediment Transport

Transforms reduce the distributions of surface-runoff and sediment-transport variables to nearexponential distributions typical of rainfall duration and intensity. Two transform parameters are determined from field measurements using either a graphical method or the method of moments. The transforms were tested on both small experimental plots and very large watersheds for the distributions of ...

Sediment transport by runoff on debris-mantled dryland hillslopes

Rate of fall-applied liquid swine manure: effects on runoff transport of sediment and phosphorus.

Reducing the delivery of phosphorus (P) from land-applied manure to surface water is a priority in many watersheds. Manure application rate can be controlled to manage the risk of water quality degradation. The objective of this study was to evaluate how application rate of liquid swine manure affects the transport of sediment and P in runoff. Liquid swine manure was land-applied and incorporat...

Investigating raindrop effects on transport of sediment and non-sorbed chemicals from soil to surface runoff

A simple modeling and laboratory investigation was carried out to investigate the raindrop effects on both sediment detachment and chemical transport from soil–water into runoff. Solute movement between soil–water and runoff is usually modeled as either a mixing model or as a diffusion-like process, both of which ignore the important roles of raindrop impact on the transport process. We hypothe...

The Effect of Convergence and Divergence on Flow Pattern and Sediment Transport in Lateral Intakes

Water supply at a desired rate at any time to meet the water requirements regardless of river discharge must be considered in the general design of intakes provided that the needs do not exceed the river flow. Due to the lack of necessary information in this field and the importance of sediment transport to the lateral intakes at river bends, this study aimed at understanding the mechanism of t...
