“…Using both stable isotopes and tritium in semi-arid New Mexico, Chapman et al (1992) deduced flow rates of between 7 and 15 m year -1 (4.8 x 10 -5 cm s -1 ) through 250-300 m of vadose zone at Carlsbad Caverns. In another semiarid region, in Israel, Even et al (1986) found isotopic homogenization to occur quickly after infiltration, but then some waters percolated rapidly while others were detained for decades in the epikarst.…”

“…This has been attributed to different flow systems (quick flow and slow flow), arid versus humid climate forcing, and variations in storage in the soil and epikarst, e.g. Mendip Hills, England (Friederich and Smart, 1982), Israel (Even et al, 1986), Niaux, France (Bakalowicz and Jusserand, 1987), Pennine karst, England (Bottrell and Atkinson, 1992), Slovenia (Kogovšek, 1997), and Mt Carmel, Israel (Arbel et al, 2008).…”

Abstract. Limestone aeolianites constitute karstic aquifers covering much of the western and southern Australian coastal fringe. They are a key groundwater resource for a range of industries such as winery and tourism, and provide important ecosystem services such as habitat for stygofauna. Moreover, recharge estimation is important for understanding the water cycle, for contaminant transport, for water management, and for stalagmite-based paleoclimate reconstructions. Caves offer a natural inception point to observe both the long-term groundwater recharge and the preferential movement of water through the unsaturated zone of such limestone. With the availability of automated drip rate logging systems and remote sensing techniques, it is now possible to deploy the combination of these methods for largerscale studies of infiltration processes within a cave. In this study, we utilize a spatial survey of automated cave drip monitoring in two large chambers of Golgotha Cave, southwestern Western Australia (SWWA), with the aim of better understanding infiltration water movement and the relationship between infiltration, stalactite morphology, and unsaturated zone recharge. By applying morphological analysis of ceiling features from Terrestrial LiDAR (T-LiDAR) data, coupled with drip time series and climate data from 2012 to 2014, we demonstrate the nature of the relationships between infiltration through fractures in the limestone and unsaturated zone recharge. Similarities between drip rate time series are interpreted in terms of flow patterns, cave chamber morphology, and lithology. Moreover, we develop a new technique to estimate recharge in large-scale caves, engaging flow classification to determine the cave ceiling area covered by each flow category and drip data for the entire observation period, to calculate the total volume of cave discharge. This new technique can be applied to other cave sites to identify highly focussed areas of recharge and can help to better estimate the total recharge volume.

“…This combined with epikarst storage in the buried Madison aquifer (previously described) might account for the decades-old water of the slow-flow domain. As an example, tritium concentrations in cave drip in Israel indicated greatly varying groundwater ages of as much as several decades (Even et al, 1986). Delayed storage in epikarst also has been discussed by Long (2009) in the northern Black Hills and elsewhere by Pinault et al (2001), and regional paleowater mixed with recent recharge was described by Plummer et al (1998).…”

This manuscript was handled by P. Baveye, Editor-in-ChiefKeywords: Groundwater Karst Parameter estimation Inverse modeling Groundwater age s u m m a r y Convolution modeling is useful for investigating the temporal distribution of groundwater age based on environmental tracers. The framework of a quasi-transient convolution model that is applicable to twodomain flow in karst aquifers is presented. The model was designed to provide an acceptable level of statistical confidence in parameter estimates when only chlorofluorocarbon (CFC) and tritium ( 3 H) data are available. We show how inverse modeling and uncertainty assessment can be used to constrain model parameterization to a level warranted by available data while allowing major aspects of the flow system to be examined. As an example, the model was applied to water from a pumped well open to the Madison aquifer in central USA with input functions of CFC-11, CFC-12, CFC-113, and 3 H, and was calibrated to several samples collected during a 16-year period. A bimodal age distribution was modeled to represent quick and slow flow less than 50 years old. The effects of pumping and hydraulic head on the relative volumetric fractions of these domains were found to be influential factors for transient flow. Quick flow and slow flow were estimated to be distributed mainly within the age ranges of 0-2 and 26-41 years, respectively. The fraction of long-term flow (>50 years) was estimated but was not dateable. The different tracers had different degrees of influence on parameter estimation and uncertainty assessments, where 3
