Sedimentology and geomorphology of tufa barrages on rock coast shore platforms

open access: yesSedimentology, EarlyView.
ABSTRACT Despite tufa deposits being widely distributed and increasingly recognised globally on rock coasts, their distribution in the tidal frame and geomorphology is poorly understood. The distribution, sedimentology and geomorphology of tufa barrages on supratidal rock coasts are assessed and their controls established.

Groundwater recharge potential zone modeling in the Wadi Al-Lith Basin, Saudi Arabia

open access: yesApplied Water Science
The management of groundwater resources is crucial in arid and semi-arid regions such as Al-Lith Basin, and therefore, the identification of suitable areas for groundwater recharge is important in solving the problem of water scarcity and ensuring the ...

Identifying solutions to face groundwater overexploitation and degradation: A policy design experiment in Tunisia

open access: yesWater and Environment Journal, EarlyView.
Overview of the process and solutions' analysis Abstract Groundwater plays an important role in achieving sustainable development goals, particularly in the Maghreb. There, groundwater management policies have been unable to stop groundwater degradation and overexploitation. In this context, it is urgent to propose concrete methodologies allowing local

Atollscape: Simulating freshwater management in Pacific Atolls. Spatial processes and time dependence issues [PDF]

open access: yes, 2003
Groundwater has long been ranked as a high priority research area by small island nations in the Pacific. It is the major source of freshwater on the atoll of Tarawa (Rep.of Kiribati) and its availability, quality, management and allocation are central ...

Assessment of Groundwater Recharge, Evaporation, and Runoff in the Drava Basin in Hungary with the WetSpass Model

open access: yesHydrology, 2019
The assessment of spatial and temporal distribution of groundwater recharge is required as an input to develop the regional groundwater model in the Drava flood plain for more accurate simulations of different management scenarios.

A High‐Precision Analytical Technique for Dissolved N2 Isotopes in Aquatic Systems: Biogeochemical Applications and Determination of Solubility Equilibrium Isotope Effects

open access: yesRapid Communications in Mass Spectrometry, Volume 39, Issue 19, 15 October 2025.
ABSTRACT Rationale The isotopic composition of dissolved dinitrogen gas (δ15N‐N2) in water can offer a powerful constraint on the sources and pathways of nitrogen cycling in aquatic systems. However, because of the large presence of atmosphere‐derived dissolved N2 in these systems, high‐precision (on the order of 0.001‰) measurements of N2 isotopes ...
