Johann Christoph Schwab et le kantisme Open
Johann Christoph Schwab was among the first members of the Berlin Academy to engage with Kant’s philosophy in the late 1780s. His memoir on the relationship between ideas and things contains numerous signs of sympathy toward Kant’s thought…
Weaving different forms of knowledge of managed aquifer recharge in a Saharan oasis (Algeria) Open

View article: Multidisciplinary approach to understand the salinization of fractured crystalline aquifers in semi-arid region
Multidisciplinary approach to understand the salinization of fractured crystalline aquifers in semi-arid region Open
In semi-arid areas, groundwater (GW) represents the most reliable resource for water supply. In the semi-arid region of Ceará (Northeastern Brazil), GW of the crystalline fractured aquifers has a salinity higher than expected in this type …
Recharge and dynamics of the Tamanrasset alluvial aquifer (Algerian Sahara) Open
Population growth and agricultural intensification are ever more demanding in water resources, and threaten their quality and quantity, especially in semi-arid and arid areas. The Sahara desert is typical of these multiple constraints and …
Impacts of climate variations and human influences on groundwater recharge in the semi-arid Trarza aquifer (SW Mauritania) Open
Hydrological processes are rapidly changing in semi-arid areas under the double constraint of climate change and anthropization. Such changes were investigated at different scales of time and space in the Trarza aquifer (SW Mauritania), a …
Multidisciplinary approach to understand the salinization of fractured crystalline aquifers in semi-arid region. Proceedings of IAHS, Open
In semi-arid areas, groundwater (GW) represents the most reliable resource for water supply. In the semi-arid region of Ceará (Northeastern Brazil), GW of the crystalline fractured aquifers has a salinity higher than expected in this type …

Explaining the groundwater salinity of hard-rock aquifers in semi-arid hinterlands using a multidisciplinary approach Open
Shallow crystalline groundwater in the semi-arid hinterland of Ceará is brackish or saline with mixed chloride or sodium chloride facies. Very few hydrochemical data are available for the area and the drivers behind this salinity are not c…
A not-so-paradoxical groundwater rise in semi-arid environments Open
Semi-arid areas are usually associated with decreasing water levels due to groundwater overexploitation, that threatens the sustainability of the water resource and causes negative environmental impacts. More surprisingly, semi-arid areas …
Recharge and groundwater dynamics in the Tamanrasset alluvial aquifer (Algerian Sahara) Open
Social, economic and environmental changes are deeply affecting the entire Earth. Population growth and agricultural intensification are ever more demanding in natural resources, and especially water that is now threatened in both quality …
From piezometers to water actors and back again. A grounded sociohydrology towards the sharing of hydrological knowledge (Senegal River delta). Open
The Senegal River delta is characterised by two distinct features. First is the rich historical link between people and water. In this area shaped by the river flow, inhabitants developed multiple water-related activities over history and …
Generating knowledge from water management situations: a pragmatist approach to socio-hydrology Open
We consider socio-hydrological systems (SHS) as complex sets of interacting and organized social and biophysical constituents, embedded in locally grounded pathways. As interdependencies among constituents increase and global changes chall…
Use of a multi-tracer approach for the hydrogeochemical characterization of fractured crystalline aquifers in semi-arid region Open
In crystalline aquifers, groundwater resources are generally scarce and may be subject to salinization, notably in semi-arid areas. In semi-arid Northeastern Brazil (NEB), the processes at the origin of the high and heterogeneous salinity …
A socio-hydrological journey around the Wadi Merguellil in central Tunisia Open
The Wadi Merguellil, the main watercourse of the Merguellil basin in central Tunisia, has experienced an extremely marked socio-hydrological evolution. It is currently intermittent over most of its course, but the statements of farmers and…
Impacts of climate variations and human influences on groundwater recharge in the semi-arid Trarza aquifer (SW Mauritania) Open
Even in regions with very sparse population, hydrological processes are rapidly changing in semi-arid areas under the double constraint of climate change and anthropization. This is visible in the Trarza aquifer in south-western Mauritania…
Multiscale and multifactor sea-groundwater interactions in southwestern Mauritania Open
Coastal aquifers in semi-arid zones are particularly exposed to environmental changes because of their low annual recharge and the increasing anthropogenic pressure. This is particularly the case in the Trarza phreatic aquifer (SW Mauritan…
Diverging Water Ages Inferred From Hydrodynamics, Hydrochemical and Isotopic Tracers in a Tropical Andean Volcano-Sedimentary Confined Aquifer System Open
Hydrogeology in the Andes cordillera reflects its complex geological history. In most cases, groundwater flows through fractures and faults that compartmentalize the volcanic material, and through the primary porosity of the volcano-sedime…
Inspiring a Broader Socio‐Hydrological Negotiation Approach With Interdisciplinary Field‐Based Experience Open
Socio‐hydrology advanced the field of hydrology by considering humans and their activities as part of the water cycle, rather than as external drivers. Models are used to infer reproducible trends in human interactions with water resources…
Sub-chapter 2.3.5. Changes in Mediterranean groundwater resources Open
Introduction The strong variability in space and time of all components of the hydrological cycle is a fundamental feature of the Mediterranean region (e.g. Cudennec et al. 2007). Its most visible marker is the succession of droughts and f…
