“…Additional data were trimmed from A c c e p t e d M a n u s c r i p t 7 the data during the inversion process. The HF method has been utilized successfully within a number of applications published in the peer-reviewed literature (Halihan et al, 2005;Ong et al, 2010;Heeren et al, 2010;Heeren et al, 2011;Keppel et al, 2011;Halihan et al, 2011;Halihan et al, 2012;Christenson et al, 2012;Halihan et al, 2013;Heeren et al, 2014). Miller et al (2014) also demonstrated that the HF method was more suitable for the gravel-dominated alluvial floodplains investigated in this study by comparing the technique to the standard dipoledipole ER array and inversion.…”

Floodplains are composed of complex depositional patterns of ancient and recent stream sediments, and research is needed to address the manner in which coarse floodplain materials affect stream/groundwater exchange patterns. Efforts to understand the heterogeneity of aquifers have utilized numerous techniques typically focused on point-scale measurements; however, in highly heterogeneous settings, the ability to model heterogeneity is dependent on the data density and spatial distribution. The objective of this research was to investigate the correlation between broad-scale methodologies for detecting heterogeneity and the observed spatial variability in stream/groundwater interactions of gravel-dominated alluvial floodplains. More specifically, this study examined the correlation between electrical resistivity (ER) and alluvial groundwater patterns during a flood event at a site on Barren Fork Creek (BFC), in the Ozark ecoregion of Oklahoma, USA, where chert gravels Downloaded by [University of Tennessee, Knoxville] at 16:50 22 December 2014 A c c e p t e d M a n u s c r i p t 2 were common both as streambed and floodplain material. Water table elevations from groundwater monitoring wells for a flood event on May 1-5, 2009 were compared to electrical resistivity maps at various elevations. Areas with high electrical resistivity matched areas with lower water table slope at the same elevation. This research demonstrated that electrical resistivity approaches were capable of indicating heterogeneity in surface water/groundwater interactions, and that these heterogeneities were present even in an aquifer matrix characterized as highly conductive. Portions of gravel-dominated floodplain vadose zones characterized by high hydraulic conductivity features can result in heterogeneous flow patterns when the vadose zone of alluvial floodplains activates during storm events.

“…Interestingly, Keppel et al . () described typical phytohermal framestone tufa deposited from 20 to 27°C waters and interpreted them as super‐ambient temperature meteogene ground water in origin, based on the lack of significant chemical or temperature variance between samples collected at different times of the year.…”

“…These processes may cause tufa deposition near a single subaerial resurgence point (for example, perched springline, Pedley, ; mound springs, Keppel et al ., ) and the deposit may be composed predominantly of highly irregular, very porous macrobiota dominated, depositional fabrics (phytohermal facies). Alternatively, tufa may develop at multiple resurgence sites along a watercourse to produce barrage tufas (Pedley et al ., ; Pentecost, ).…”

Decoding tufa and travertine (fresh water carbonates) in the sedimentary record: The state of the art

Traditionally, fresh water carbonate research has focused on the sedimentology and palaeontology of ancient lacustrine deposits. Lithofacies in such low-energy deposits are typically fine-grained, developed uniformly in a generally concentric distribution ('bulls-eye' pattern) and are predictable even when preserved imperfectly. In contrast, because of their local lithofacies and palaeontological complexities, fluvial carbonates were either delegated to a status of 'minor geomorphological features' or barely considered prior to the 1970s. This viewpoint was based on the depositional record of fluvial and spring-fed fresh water carbonates, which were considered to be restricted generally to localized karstic areas. Such deposits are often preserved as scattered patches of ambient temperature tufa. Occasionally, however, in active tectonic areas, localized travertine deposits are also developed from deeply circulating hydrothermal waters. With a few exceptions (for example, basins with high subsidence rates or in arid climate zones), these fresh water carbonates are prone to erosion from continuing river incision and thus may not be preserved in the geological record. A partial record of fluvial and springdeposited carbonates is often preserved in Quaternary deposits, but the record in older deposits is typically fragmentary and often diagenetically modified. Yet once their unique facies architecture (and specialized nomenclature) is understood, these carbonates provide an important record of past sedimentological cycles of great value in palaeoenvironmental landscape modelling. The emphasis of modern research is to acquire information that explains how active systems function. In this respect, tufas reveal much of how carbonate precipitation is a shared product of physico-chemical and microbiological biomediation processes. Likewise, travertines not only show an intimate interrelation with active tectonism but also hold great potential as monitors of past volcanic carbon dioxide emissions. In addition, both tufas and travertines contain palynological records that can be used as proxy indicators of climate change. Perhaps no other field of sedimentology has witnessed more developments and applications over such a brief period of study.

“…The data acquisition and inversion utilized a proprietary Oklahoma State University method (HF, OSU Office of Intellectual Property, 2004;Halihan et al, 2005) to acquire apparent resistivity data and convert them to a model resistivity profile. The HF method has been utilized successfully within a number of applications published in the peer-reviewed literature (Halihan et al, 2005;Ong et al, 2010;Heeren et al, 2010Heeren et al, , 2011Keppel et al, 2011;Halihan et al, 2011Halihan et al, , 2012Halihan et al, , 2013Christenson et al, 2012;Heeren et al, 2014). The method has even been used and accepted by government agencies, such as the Department of Defense and U.S. EPA.…”
