[1] Variability in sediment hydraulic properties associated with landscape depositional and erosional features can influence groundwater recharge processes by affecting soil-water storage and transmission. This study considers recharge to aquifers underlying river-incised glaciated terrain where the distribution of clay-rich till is largely intact in upland locations but has been removed by all...

This paper presents a complete analytical solution to describe tidal groundwater level fluctuations in a coastal subsurface system. The system consists of two aquifers and a leaky layer between them. Previous solutions of Jacob [Flow of groundwater, in: H. Rouse (Ed.), Engineering Hydraulics, Wiley, New York, 1950, pp. 321–386], Jiao and Tang [Water Resour.

The area of interest comprises 1.6 million km² the Horn Africa, extending 60 km offshore Gulf Aden and Indian Ocean, delimited by Tana River in Kenya Rift Valley Ethiopia. Deep (> 400 m) groundwater resources are virtually unexplored Africa. One main challenges this vast sparsely documented area, is producing solid geological models. This paper presents a first-order assessment deep structure w...

Sources of spring predictability of the hydrological system over France were studied on a seasonal time scale over the 1960–2005 period. Two random sampling experiments were set up in order to test the relative importance of the land surface initial state and the atmospheric forcing. The experiments were based on the SAFRAN-ISBA-MODCOU hydrometeorological suite which computed soil moisture and ...

The proposal of the Quilmes Tectonic Trough (Fosa tectónica de – FQ) as extension southern end Santa Lucía basin in Uruguay and its connection to Salado Argentina suggest existence a large sedimentary volume capable housing new aquifer on La Plata River coast. However, volumes that form FQ are hidden under thick, recently deposited cover, thus, there is lack studies nature this formation. Never...

Relationships between surface waters and groundwaters at basin scale are rarely investigated but have important implications for water resource development management. Here, we integrate evidence from geochemical tracers piezometry to advance the understanding of regional-scale, groundwater–surface interactions in River Awash Basin Ethiopia. Hydrological characteristics consistent with those ob...

SUMMARY Most of water reservoirs are underground and therefore challenging to monitor. This is particularly the case karst aquifers which knowledge mostly based on sparse spatial temporal observations. In this study, we propose a new approach, supervised machine learning algorithm, Random Forests, continuous seismic noise records, that allows prediction river height. The study site aquifer in J...

This study presents an approach for obtaining limited sets of realizations of hydraulic conductivity (K) of multiple aquifers using simulated annealing (SA) simulation and spatial correlations among aquifers to simulate realizations of hydraulic heads and quantify their uncertainty in the Pingtung Plain, Taiwan. The proposed approach used the SA algorithm to generate large sets of natural logar...

This paper explores the signi®cance of groundwater dominance in the surface water system through a combination of review and an exposition of the general hydrology, ecology and geomorphology of rivers draining the main UK aquifers. Groundwater dominance is shown to vary according to the nature of the aquifer lithology, the mechanism of groundwater:surface water interaction and the scale at whic...
