An optical laser device for mapping 3D geometry of underwater karst structures : first tests in the Ox Bel’Ha system, Yucatan, Mexico = Un dispositivo láser óptico para la cartografía 3D de la geometría de estructuras kársticas submarinas: primeros resultados en el sistema de Ox Bel’Ha, Yucatán, México

In the course of extended hydrological studies in the coastal Karst plain of Yucatan, near the town of Tulum amongst others, a novel laser scanning device was developed and applied for the acquisition of the 3d-geometry of ground water conduits. The method is derived from similar industrial systems and for the first time adapted to the specific measurement conditions in underwater cave systems....

Infiltration under snow cover : Modeling approaches and predictive uncertainty

Meeks, Jessica ; Moeck, Christian ; Brunner, Philip ; Hunkeler, Daniel

In: Journal of Hydrology, 2017, vol. 546, p. 16-27

Groundwater recharge from snowmelt represents a temporal redistribution of precipitation. This is extremely important because the rate and timing of snowpack drainage has substantial consequences to aquifer recharge patterns, which in turn affect groundwater availability throughout the rest of the year. The modeling methods developed to estimate drainage from a snowpack, which typically rely on...

Snowmelt infiltration and storage within a karstic environment, Vers Chez le Brandt, Switzerland

Meeks, Jessica ; Hunkeler, Daniel

In: Journal of Hydrology, 2015, vol. 529, no. Part 1, p. 11-21

Even though karstic aquifers are important freshwater resources and frequently occur in mountainous areas, recharge processes related to snowmelt have received little attention thus far. Given the context of climate change, where alterations to seasonal snow patterns are anticipated, and the often-strong cou- pling between recharge and discharge in karst aquifers, this research area is of great...
