Water Intensity of Transportation [PDF]

open access: yesEnvironmental Science & Technology, 2008
As the need for alternative transportation fuels increases, it is important to understand the many effects of introducing fuels based upon feedstocks other than petroleum. Water intensity in "gallons of water per mile traveled" is one method to measure these effects on the consumer level.

A Method for Calculating Water Demand for Sediment Transport Based on the Principles of River Dynamics

open access: yes, 2023
Sufficient water is pivotal in maintaining the stability of boundaries in sandy river systems. However the current methodologies employed for computing the water demand for sediment transport in rivers frequently neglect this component.

Water transport through carbon nanotubes with defects [PDF]

open access: yes, 2012
Non-equilibrium molecular dynamics simulations are performed to investigate how changing the number of structural defects in the wall of a (7,7) single-wall carbon nanotube (CNT) affects water transport and internal fluid dynamics. Structural defects are

Water transport revisited [PDF]

open access: yesThe Journal of Physiology, 1999
Nearly forty years ago Curran & MacIntosh (1962) presented experimental evidence for a model of water transport that would satisfy a question posed by such famous physiologists as Heidenhain and Reed before the turn of the century: how can the intestine accomplish transport of water from one isotonic compartment (the bowel lumen) to another (the blood)?
