“…These suitable ranges (presented in Equation ) enable characterization of the persistence of hyporheic zones under temporary connection and disconnection between surface water and groundwater systems. In fact, a relatively constant river stage can be commonly found in rivers and streams that are regulated by reservoir operations in semiarid environments (Pearson et al., 2022). Additionally, this simplification allows us to focus on groundwater dynamics.…”

“…Climate change and increasing population have led to increasing water demand and groundwater withdrawal, which may eventually contribute to decreased river flow and lowered groundwater table (Heidari et al., 2021; Jasechko et al., 2021). Ephemeral or intermittent streams, especially in semi‐arid regions, can be caused or enhanced by climate disturbances such as drought (Hammond et al., 2021; Zipper et al., 2021), and these systems may undergo extreme hydrologic transitions from connection to disconnection (Fuchs et al., 2019; Pearson et al., 2022).…”

“…Given the strong modulating effects of regional groundwater fluxes, it is imperative to assess the limiting range of gaining, losing, and disconnected river‐aquifer conditions under which hyporheic zones persist or even exist. The spatial distribution of infiltration and seepage through a surface water source depends on the state of connection (Brunner, Cook, & Simmons, 2009; Brunner, Simmons, & Cook, 2009; Pearson et al., 2022; Quichimbo et al., 2020; Shanafield et al., 2012), which can be paramount to understanding biogeochemical cycling of nutrients and pollutants within the hyporheic zone (Findlay, 1995; Krause et al., 2011; Shabaga & Hill, 2010). Some rivers can have transitions between a gaining‐river and losing‐river systems (Wroblicky et al., 1998) and a single river can comprise some gaining reaches and other locations under losing conditions.…”

Hyporheic zones are commonly regarded as resilient and enduring interfaces between groundwater and surface water in river corridors. In particular, bedform‐induced advective pumping hyporheic exchange (bedform‐induced exchange) is often perceived as a relatively persistent mechanism in natural river systems driving water, solutes, and energy exchanges between the channel and its surrounding streambed sediments. Numerous studies have been based on this presumption. To evaluate the persistence of hyporheic zones under varying hydrologic conditions, we use a multi‐physics framework to model advective pumping bedform‐induced hyporheic exchange in response to a series of seasonal‐ and event‐scale groundwater table fluctuation scenarios, which lead to episodic river‐aquifer disconnections and reconnections. Our results suggest that hyporheic exchange is not as ubiquitous as generally assumed. Instead, the bedform‐induced hyporheic exchange is restricted to a narrow range of conditions characterized by minor river‐groundwater head differences, is intermittent, and can be easily obliterated by minor losing groundwater conditions. These findings shed light on the fragility of bedform‐induced hyporheic exchange and have important implications for biogeochemical transformations along river corridors.

“…Among different geophysical techniques, electrical resistivity tomography (ERT) method has a long history in solving a variety of engineering, environmental and hydrogeological problems [ 14 , 15 , 16 ]. The most common applications include detection of different types of subsurface voids and cavities [ 17 , 18 , 19 , 20 ], mineral exploration [ 21 , 22 ], characterization of landfills, mining dumps and heap leaching facilities [ 23 , 24 , 25 , 26 , 27 ], and groundwater studies [ 28 , 29 ]. In recent years, the ERT method has continuously proven itself as an efficient element to be integrated in hydrogeological risk mitigation strategies, thanks to its potential to monitor changes in water saturation of the subsurface material and to detect seepage zones [ 30 , 31 , 32 , 33 , 34 , 35 , 36 , 37 , 38 , 39 , 40 , 41 ].…”

This paper addresses the problem of removing 3D effects as one of the most challenging problems related to 2D electrical resistivity tomography (ERT) monitoring of embankment structures. When processing 2D ERT monitoring data measured along linear profiles, it is fundamental to estimate and correct the distortions introduced by the non-uniform 3D geometry of the embankment. Here, I adopt an iterative 3D correction plus 2D inversion procedure to correct the 3D effects and I test the validity of the proposed algorithm using both synthetic and real data. The modelled embankment is inspired by a critical section of the Parma River levee in Colorno (PR), Italy, where a permanent ERT monitoring system has been in operation since November 2018. For each model of the embankment, reference synthetic data were produced in Res2dmod and Res3dmod for the corresponding 2D and 3D models. Using the reference synthetic data, reference 3D effects were calculated to be compared with 3D effects estimated by the proposed algorithm at each iteration. The results of the synthetic tests showed that even in the absence of a priori information, the proposed algorithm for correcting 3D effects converges rapidly to ideal corrections. Having validated the proposed algorithm through synthetic tests, the method was applied to the ERT monitoring data in the study site to remove 3D effects. Two real datasets from the study site, taken after dry and rainy periods, are discussed here. The results showed that 3D effects cause about ±50% changes in the inverted resistivity images for both periods. This is a critical artifact considering that the final objective of ERT monitoring data for such studies is to produce water content maps to be integrated in alarm systems for hydrogeological risk mitigation. The proposed algorithm to remove 3D effects is thus a rapid and validated solution to satisfy near-real-time data processing and to produce reliable results.
