TL;DR: The worldwide distribution and water supply of water towers (snowy or glacierized mountain ranges) is indexed, showing that the most important water towers are also the most vulnerable to socio-economic and climate-change stresses, with huge potential negative impacts on populations downstream.
Journal ArticleDOI
Solute transport in variable-aperture fractures: An investigation of the relative importance of Taylor dispersion and macrodispersion
TL;DR: In this article, a combination of physical experiments and computational simulations is used to test a theoretical model in which the effective longitudinal dispersion coefficient DL is expressed as a sum of the contributions of these three dispersive mechanisms.
Journal ArticleDOI
Saturated flow in a single fracture: evaluation of the Reynolds Equation in measured aperture fields
TL;DR: In this paper, the authors employed a light transmission technique with well-defined accuracy (approximately 1% error) to measure aperture fields at high spatial resolution (approximately 0.015 cm).
Journal ArticleDOI
Glacier crevasses: Observations, models, and mass balance implications
William Colgan,William Colgan,Harihar Rajaram,Waleed Abdalati,Cheryl McCutchan,Ruth Mottram,M. S. Moussavi,S. Grigsby +7 more
TL;DR: In this paper, the authors review the findings of approximately 60 years of in situ and remote sensing studies of glacier crevasses, as well as the three broad classes of numerical models now employed to simulate crevasse fracture.
Journal ArticleDOI
Influence of aperture variability on dissolutional growth of fissures in karst formations
R. Blair Hanna,Harihar Rajaram +1 more
TL;DR: The influence of aperture variability on dissolutional growth of fissures is investigated on the basis of two-dimensional numerical simulations in this paper, where the size of the fissure aperture before dissolution is modeled as a Gaussian stationary isotropic random field.
