Thermal effects on flow and salinity distributions in heterogeneous coastal aquifers with fixed-flux inland boundaries

open access: yesFrontiers in Environmental Science, 2022
Freshwater-seawater (FW-SW) temperature contrasts widely exist in natural coastal aquifers. The significant effects of thermal forcing on water flow and salinity distributions for homogeneous aquifers have been demonstrated recently, however, the impact ...

The coastal transition zone is an underexplored frontier in hydrology and geoscience

open access: yesCommunications Earth & Environment, 2022
Improvements in coastal shallow water geophysical technologies and drilling must be coupled with numerical modelling in order to close the knowledge gaps that exist around coastal aquifers, suggests a synthesis of methodological challenges and future ...

Use of galdit index to evaluate salinization vulnerability in boa viagem aquifer – Recife metropolitan region

open access: yesRevista Águas Subterrâneas, 2015
Recife plain is a estuarine region which has an average elevation ranging from 2 to 10 m, being framed by topographic elevation shaped as small hills. Recife area is crossed by several rivers, streams and wetlands and is a highly sensitive area to tidal ...

Hydrogeology of coastal aquifers: Introduction

open access: yesBoletín Geológico y Minero, 2022
Es una realidad que en la mayor parte del planeta las grandes urbes se suelen desarrollar en las áreas costeras. Asimismo, es frecuente que las zonas litorales tengan también un desarrollo agrícola y turístico muy notable, algo menos en las áreas kársticas costeras (Fidelibus and Pulido- Bosch, 2018).

From Lab to Landscape: Environmental Biohybrid Robotics for Ecological Futures

open access: yesAdvanced Robotics Research, EarlyView.
This Perspective explores environmental biohybrid robotics, integrating living tissues, microorganisms, and insects for operation in real‐world ecosystems. It traces the leap from laboratory experiments to forests, wetlands, and urban environments and discusses key challenges, development pathways, and opportunities for ecological monitoring and ...

Intensively exploited Mediterranean aquifers: resilience to seawater intrusion and proximity to critical thresholds [PDF]

open access: yesHydrology and Earth System Sciences, 2014
We investigate seawater intrusion in three prominent Mediterranean aquifers that are subject to intensive exploitation and modified hydrologic regimes by human activities: the Nile Delta, Israel Coastal and Cyprus Akrotiri aquifers.

Groundwater Rise Sustains the World's Largest Alpine Water System Under Global Warming

open access: yesAdvanced Science, EarlyView.
Shallow groundwater depth (SGWD) across the non‐permafrost plains of the Qinghai–Xizang Plateau decreased at averagely 0.02 m year−1, adding 31.44 Gt of freshwater storage from 2000 to 2020 and sustaining ∼53 500 km2 of alpine ecosystems. A vadose‐zone capacity of 426.6 Gt reveals these aquifers as promising reservoirs, highlighting groundwater's ...

Frozen Ground Induces Seawater Retreat in Coastal Unconfined Aquifers

open access: yesGeophysical Research Letters
While seawater intrusion (SWI) in coastal aquifers has been extensively investigated, most studies focused on unfrozen conditions. In many cold regions, frozen ground is common, yet its impact on SWI remains poorly understood.

A Systemic Model for Understanding Business Interactions With Biodiversity and Ecosystems

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Biodiversity loss and ecosystem degradation represent critical threats to human well‐being and economic resilience, challenging businesses to understand and manage their interdependence with natural systems. This study develops a systemic framework—the BioModel—that elucidates the reciprocal relationship between businesses, biodiversity, and ...
