Drainage and siphoning of a karstic spring: a case study [PDF]

open access: yes, 2016
The Fuentetoba Spring, with a mean flow of 210 L s-1, releases the discharge from an aquifer that comprises three hydraulically-connected synclines. The spring has a very irregular flow of between 8 L s-1 and 3,400 L s-1 due to the predominant water ...

The 2010 spring drought reduced primary productivity in southwestern China [PDF]

open access: yes, 2012
Many parts of the world experience frequent and severe droughts. Summer drought can significantly reduce primary productivity and carbon sequestration capacity. The impacts of spring droughts, however, have received much less attention.

A multi-scale approach to determine the REV in complex carbonate rocks [PDF]

open access: yes, 2013
Complex porous carbonates display heterogeneity at different scales, influencing their reservoir properties (e.g. porosity) especially since different porosity types may exist on different spatial scales.
