Role of time variant and invariant terms on soil moisture spatio‐temporal variability in a subhumid coastal wetland Open
The knowledge of soil moisture spatio‐temporal variability is highly relevant for water resources management. This paper reports an analysis of the spatial–temporal variability of soil moisture data for a small to medium‐scale soil‐sensors…

Groundwater Abstraction has Caused Extensive Ecological Damage to the Doñana World Heritage Site, Spain Open
Acreman et al. (Wetlands 42:63, 2022) reviewed evidence for ecological damage to the Doñana wetlands (UNESCO World Heritage Site [WHS] and Ramsar site), Spain, associated with intensification of groundwater use, particularly for agricultur…

Vapour source and spatiotemporal variation of precipitation isotopes in Southwest Spain Open
The δ 2 H and δ 18 O composition of 77 precipitation samples collected between January 2014 and April 2019 from two sites across the Guadalquivir Basin, SW Spain, were analysed. The first site is located in an urban area of Seville at 100 …

Quality aspects of the Doñana groundwater resources (SW-Spain) before the intensification of agriculture Open
This article presents the initial hydrochemical status of the Almonte-Marismas aquifer system in 1966 – before agricultural intensification. The investigated aquifer is of critical importance for the groundwater dependent Doñana wetland ar…

Spatial and temporal variation in precipitation isotopes at 2 locations in southwest Spain Open
The δ2H and δ18O composition of 77 precipitation samples collected between January 2014 and April 2019 from two sites across the Guadalquivir Basin, SW Spain, were analyzed. Sampling was performed within intervals of at least 14 days basis…

Analysis of water vapor adsorption in soils by means of a lysimeter and numerical modeling Open
Daily temperature oscillations can cause adsorption (and desorption) of atmospheric water vapor by soils. The resulting daily fluctuations in the amount of liquid water in the soil can be measured by high‐precision weighing lysimeters. We …

Towards flexible groundwater-level prediction for adaptive water management: using Facebook’s Prophet forecasting approach Open
There is an increasing need for accurate groundwater-level (GWL) prediction to support effective seasonal water management. It is desirable for forecasting tools to be not only accurate but also accessible for decision-makers. We test the …

Determining groundwater recharge and vapor flow in dune sediments using a weighable precision meteo lysimeter Open
Dune belts are crucial for the recharge of coastal aquifers. In spite of their hydrological relevance for the maintenance of precious natural wetland and wildlife environments and a range of other ecosystem services, only limited knowledge…
