Short summary
This study used hydrodynamic and hydrogeochemical data to understand the salinization processes of the crystalline groundwater (GW) in Ceará, Brazil. Results demonstrate that GW is generally recent and recharged by meteoric waters mainly through localized infiltration. The study suggests that GW, originally bicarbonated, becomes progressively enriched in chloride due to the dissolution and leaching of salts that have precipitated in the unsaturated zone and pond sediments during dryer periods.

In order to better understand the hydrogeological functioning of the Mornag aquifer system (NE Tunisia), chemical and isotopic (18O, 2H) analyses of water are carried out. This work highlights the fact that the water of this aquifer system is highly modified by geochemical interactions: cationic exchange and precipitation/dissolution phenomena. The water of this aquifer system has been recently recharged by direct infiltration from the boundary and in the valley of wadis.

The present study aimed to contribute to the hydrogeological knowledge of a region in the department of Santander, Colombia, which suffers from drinking water supply problems. Groundwater is exploited in the region, but there is no detailed conceptual model available to help environmental authorities manage groundwater resources. To advance the conceptual model of the region an isotope study of monthly rainfall and its temporal and spatial response in the groundwater was made.

People induce and modify droughts. However, we do not know exactly how relevant human and natural processes interact nor how to evaluate the co-evolution of people and water. Prospect theory can help us to explain the emergence of drought impacts leading to failed welfare expectations (“prospects”) due to water shortage. Our approach helps to explain socio-hydrological phenomena, such as reservoir effects, and can contribute to integrated drought management considering the local context.

This work investigates different model types for drought prediction in a dryland region. Consequently, the performances of seasonal reservoir volume forecasts derived by a process-based and a statistical hydrological model were evaluated. The process-based approach obtained lower accuracy while resolution and reliability of drought prediction were comparable. Initialisation of the process-based model is worthwhile for more in-depth analyses, provided adequate rainfall forecasts are available.

The feasibility of drought prediction is assessed in the Brazilian northeast. The models were provided by a regional agency and a European meteorological agency and downscaling was done using three empirical models. This work showed that the combination of different forecast and downscaling models can provide skillful predictions of drought events on timescales relevant to water managers. But the models also showed little to no skill for quantitative predictions of monthly precipitation.

Short summary
The isotopic characterization of rainwater in the semi-arid regions of Northeastern Brazil (NEB) was only addressed by a few studies. Moreover, the isotopic data available were mainly linked to the establishment of the Global Network of Isotopes in Precipitation, which was paralyzed in the 1990s despite the extensive use of these data to improve the global knowledge of hydrological processes. This study allowed to improve the characterization of the isotopic signal of precipitation in NEB.
