“…Even in the case of open channel conduits, the discharge pulse, which travels as a kinematic wave, will arrive before the event water. In contrast, spring electrical conductivity perturbations can record event water arrival (e.g., Raeisi et al, 2007), and electrical conductivity interacts more slowly with the rock surrounding a conduit than temperature (Birk et al, 2006;Covington et al, 2012). Thus, in many cases, retardation may be estimated as the time difference between the electrical conductivity and temperature peaks or troughs.…”

Abstract. Water temperature is a non-conservative tracer in the environment. Variations in recharge temperature are damped and retarded as water moves through an aquifer due to heat exchange between water and rock. However, within karst aquifers, seasonal and short-term fluctuations in recharge temperature are often transmitted over long distances before they are fully damped. Using analytical solutions and numerical simulations, we develop relationships that describe the effect of flow path properties, flow-through time, recharge characteristics, and water and rock physical properties on the damping and retardation of thermal peaks/troughs in karst conduits. Using these relationships, one can estimate the thermal retardation and damping that would occur under given conditions with a given conduit geometry. Ultimately, these relationships can be used with thermal damping and retardation field data to estimate parameters such as conduit diameter. We also examine sets of numerical simulations where we relax some of the assumptions used to develop these relationships, testing the effects of variable diameter, variable velocity, open channels, and recharge shape on thermal damping and retardation to provide some constraints on uncertainty. Finally, we discuss a multitracer experiment that provides some field confirmation of our relationships. High temporal resolution water temperature data are required to obtain sufficient constraints on the magnitude and timing of thermal peaks and troughs in order to take full advantage of water temperature as a tracer.

“…According to Lakey and Krothe (1996), the delivery mechanism for this water is rapid displacement of water within or in direct contact with conduits, so that pre-event water is quickly transported to karst springs. These techniques have focused on storm-flow hydrographs from springs (Lee & Krothe 2001) and only limited work interpreting the effects of conduit geometry on water geochemistry has been completed either at springs (Luhman et al 2012) or within the conduit of a cave (Raeisi et al 2007).…”

Using isotopes of dissolved inorganic carbon species and water to separate sources of recharge in a cave spring, northwestern Arkansas, USA Blowing Spring Cave in northwestern Arkansas is representative of cave systems in the karst of the Ozark Plateaus, and stable isotopes of water (δ 18 O and δ 2 H) and inorganic carbon (δ 13 C) were used to quantify soil-water, bedrock-matrix water, and precipitation contributions to cave-spring flow during storm events to understand controls on cave water quality. water samples from recharge-zone soils and the cave were collected from March to May 2012 to implement a multicomponent hydrograph separation approach using δ O only changed by approximately 3‰ and 1‰, respectively. The isotopic compositions of precipitation and pre-event (i.e., soil and bedrock matrix) water were isotopically similar and the two-component hydrograph separation was inaccurate, either overestimating (>100%) or underestimating (<0%) the precipitation contribution to the spring. During the storm event, spring DIC and δ creased to a minimum of 8.6 mg/L and -16.2‰, respectively. If the contribution from precipitation was assumed to be zero, soil water was found to contribute between 23 to 72% of the total volume of discharge. Although the assumption of negligible contributions from precipitation is unrealistic, especially in karst systems where rapid flow through conduits occurs, the hydrograph separation using inorganic carbon highlights the importance of considering vadose-zone soil water when analyzing storm chemohydrographs.

“…As described above, chemographs can be combined with hydrographs in order to gain insights into the behavior of the karst system, particularly in response to intense precipitation events or droughts (Grasso et al 2003;Raeisi et al 2007). …”
