“…The sampling frequency election was based on the water level response to the seismic activity on Mexicali Valley, analyzed and reported in a previous study [23]. Detailed inspection of the water level did not show a significant response to local seismic activity (local magnitude ≤ 4.0) recorded by IRIS [52].…”

“…The Mexicali aquifer in the Delta of the Colorado River Basin has been studied and assessed in previous hydrogeological studies [18][19][20]. Mexicali Valley aquifer properties and poroelastic parameters, such as hydraulic conductivity, storage coefficient, hydraulic diffusivity, and static volume strain efficiency have been obtained, calculated, and compiled [18,[21][22][23]. However, there are many data gaps, especially concerning porosity, specific storage, transmissivity, compressibility, and Skempton's coefficients because of the high costs in terms of time and effort.…”

Data on the hydrologic properties of aquifers are frequently not available or are spatially limited; additionally, their determination through aquifer tests is often logistically complicated and economically expensive. This study aimed to estimate aquifer properties by analyzing the water level response for the effects of barometric pressure and earth tide. Harmonic analysis of the time series of water level and barometric pressure recorded in three boreholes in the Mexicali aquifer provided reasonable values of porosity, specific storage, transmissivity, and compressibility of the rock materials that constitute the alluvial aquifer. The representative values of porosity (14-20%), specific storage (1.74-6.23 × 10 −6 m-1), transmissivity (8.57-8.66 × 10 −7 m 2 •s-1), and compressibility (3.90-8.21 × 10 −10 Pa-1) were obtained. These values were consistent with the sediment types identified in the proximity of the wells analyzed. The results of this study show that the analysis of water level response to natural phenomena is a low-cost tool that provides reasonable estimates of aquifer properties. This advantage is particularly relevant in the study of aquifers where the available hydrological information is insufficient.

“…Finally, available publications offer a wide range of demonstration of the tidal method's capability in defining aquifer conceptual models and its parameters such as hydraulic diffusivity, transmissivity, hydraulic conductivity, storage, and confinement conditions, among other factors [47,[52][53][54][55][56][57].…”

Hydrogeological data availability is often limited to local areas where usual in situ tests or methods are applied (slug/bail or pumping tests, Electrical Resistivity Tomography (ERT)). Because most problems (e.g., saltwater intrusion mitigation) require problem analysis on larger scales (catchment or sub catchment), hydrogeological identification of global character is preferable. This work leads to the determination of aquifer hydrogeological parameters on the basis of observed sea level, groundwater piezometric head found inland, and barometric pressure. When applied to observed signals, the approach led efficiently to final hydrogeological characterization. After identification of dominant tidal constituents from observed signals, barometric efficiency was successfully determined. Following available information on geological settings, an appropriate conceptual model was applied and updated to count for polychromatic signals. Final determination of hydrogeological parameters relied on root mean square error (RMSE) minimization and led to determination of (i) presence of three stratigraphic units: unconfined sandy aquifer on the top, a confining layer made of clay, and a confined gravel layer; (ii) existence of the clay layer under the sea with a total length of 1400 m; (iii) a clay layer has been identified as confining one by both spectral analysis and determined leakance value; and (iv) estimated confined aquifer specific storage ranging from 2.87 × 10−6 to 4.98 × 10−6 (m−1), whereas hydraulic conductivity ranged from 7.0 × 10−4 to 7.5 × 10−3 (m s−1). Both range intervals corresponded to previous in situ findings conducted within the area of interest.
