Water scarcity and quality degradation represent real threats to economic, social, and environmental development of arid and semi-arid regions. Drip irrigation associated to Deficit Irrigation (DI) has been investigated as a water saving technique. Yet its environmental impacts on soil and groundwater need to be gone into in depth especially when u...
Karst aquifers in the Mediterranean region are crucial for water supply and agriculture but are increasingly threatened by climate change and overexploitation. The Jebel Zaghouan aquifer, historically significant for supplying Carthage and Tunis, serves as the focus of this study, which aims to evaluate its availability, quality, and vulnerability...
From 2006 to 2020, groundwater investigations were conducted in the Korba coastal aquifer in northern Tunisia along two flow paths (transects S1 and S2), perpendicular to the shoreline. Groundwater sampling, hydrodynamic monitoring, and electrical tomography imaging were performed in situ. Geochemical analysis (Ionic ratios, ionic deltas, conventio...
Irrigation in traditional oases in the Mena region was possible in the past via traditional techniques (foggaras, tabia) and a relative availability of water resources. To promote the development of sustainable oases, in the context of global changes and water resources scarcity and degradation, an assessment of an innovative subsurface irrigation...
Irrigated areas, mainly in arid regions, are threatened by salinization processes. Climate change inducing temperature rise and rainfall depletion are expected to enhance these processes. Numerical models are often used to predict salinization in the root zone as well as water and solute fluxes reaching groundwater. Climatic data, mainly rainfall,...
In Tunisia, the phenomenon of illicit drilling has existed since the 1980s in both southern and central Tunisia. However, since 2011, with the weakening of the administration, several farmers and landowners have been drilling in a frantic manner in the various aquifers throughout the country. According to DGRE 1 , aquifers are in advanced overexplo...
Approximately half of Tunisia's irrigated area suffers from soil salinization due to arid and semi-arid conditions, irrigation with low-quality water, shallow and saline groundwater, and poor drainage. To manage salt-affected soils, efficient assessment methods are needed to map soil salinity in irrigated lands and to evaluate the performance of cr...
Estimating crop evapotranspiration (ETa) is an important requirement for a rational assessment and management of water resources. The various remote sensing products allow the determination of crops’ biophysical variables integrated in the evaluation of ETa by using surface energy balance (SEB) models. This study compares ETa estimated by the simpl...
Approximately half of Tunisia's irrigated area suffers from soil salinization due to arid and semi-arid conditions, irrigation with brackish water, shallow and saline groundwater, and poor drainage. To manage salt-affected soils, efficient assessment methods are needed to map soil salinity in irrigated lands and to evaluate the performance of crop,...
The artificial recharge (AR) of groundwater is considered among the climate change adaptation measures. This measure helps tackling water resources scarcity and enhances water resources availability for several needs, mainly irrigation. In this respect, AR with treated wastewater was planned by Ben Arous water authority in the Mornag aquifer (north...
Real-time measurement of soil water content (θ) and pore electrical conductivity (ECp) is essential to improve water irrigation efficiency and agricultural productivity. Low-cost frequency domain reflectometry (FDR) sensors are now representing a powerful tool for irrigation management purposes. However, compared to the time domain reflectometry (T...
Groundwater recharge is one of the most important terms of water budget, and its assessment is crucial for groundwater management and protection. Several methods have been tested for different climatic and hydrogeological conditions for both diffuse and focused recharge. The present paper proposes to combine a geochemical technique and a numerical...
Capacitance sensors are widely used in agriculture for irrigation and soil management purposes. However, their use under saline conditions is a major challenge, especially for sensors operating with low frequency. Their dielectric readings are often biased by high soil electrical conductivity. New calculation approaches for soil water content (θ) a...

In this work, we conducted two laboratory column experiments on an undisturbed sandy soil. The first deals with a percolation-drainage experiment whereas the second deals with an infiltration of a constant water flux at the surface of the unsaturated soil. A Bayesian assessment of the soil parameters is performed for both experiments with the Marko...
Infiltration is defined as the entry of water from the surface into the subsurface.
Introduction Infiltrated water may originate from rainfall; irrigation; water bodies such as ponds, rivers, and lakes; or other anthropogenic activities. The terms infiltration and percolation are frequently interchangeably used even though they represent two different...

Aquifer recharge with treated wastewater (TWW) is considered as a climate change
adaptation measurement. In this context, groundwater artificial recharge with TWW is planned in Mornag aquifer (North of Tunisia) in the frame of an integrated water resources management project in the governorate of Ben Arous. This recharge aims to overcome the probl...
Irrigation return fluxes and solute recycling are very important mechanisms impacting groundwater quality and water resources management. Numerical models are often used to estimate water and solute fluxes reaching groundwater in irrigated areas. Climatic data mainly rainfall have an important influence on the estimation of those fluxes. the presen...
Groundwater sampling and piezometric measurements were carried out along two flow paths (corresponding to two transects) in Korba coastal plain (Northeast of Tunisia). The study aims to identify hydrochemical processes occurring when seawater and freshwater mix. Those processes can be used as indicators of seawater intrusion progression and freshwa...
Coastal aquifers are at threat of salinization in most parts of the world. This study was carried out in coastal shallow aquifers of Aousja-Ghar El Melh and Kalâat el Andalous, northeastern of Tunisia with an objective to identify sources and processes of groundwater salinization. Groundwater samples were collected from 42 shallow dug wells during...
Seawater intrusion and agricultural pollution are the major sources of groundwater contamination and salinization in coastal irrigated areas. The Korba coastal aquifer, located in the Cap Bon peninsula, North-East of Tunisia, has been intensively exploited since the seventies. Several studies reported the sharp piezometric drop and groundwater sali...
Groundwater samples were taken from Korba coastal aquifer from June 2006 to March 2008. The sampling was performed in two transects perpendicular to the sea and following a flow path. Seawater fractions and ionic deltas were estimated for all samples. Results show that direct and inverse cation exchange processes are taking place respectively in th...
Successive electrical resistivity tomography (ERT) measurements were performed during a controlled infiltration test. Thirty-two electrodes were used with a spacing of 1 m leading to an investigation depth of about 5 m. Four ERT profiles were performed during the infiltration test, each with a time-lapse of one hour. Water, with an electrical condu...
This study aims to understand and predict groundwater and soil salinisation processes in coastal irrigated areas using experimental and numerical tools. Field experiment was carried out in Korba coastal aquifer along an 8.7 km transect perpendicular to the sea. The transect is located in a piezometric depression and it is affected by seawater intru...
Drip irrigation is frequently used as a mean to improve irrigation efficiency. Recent
research, however, has shown that unsaturated solute transport may be strongly affected by
preferential flow, especially due to hydrophobic conditions in dry soil. The degree of preferential
flow using typical drip irrigation with moderately saline water for two t...
Les périmètres irrigués collectifs du nord de la Tunisie ont été équipés en drainage pour lutter conjointement contre la salinité et les engorgements hivernaux. En été, le fonctionnement du drainage est intimement lié aux pratiques de l’irrigation. Des systèmes de drainage ont été mis en place pour assurer le lessivage des sels et éviter l’hydromor...
