Hard rocks or crystalline rocks (ie, plutonic and metamorphic rocks) constitute the basement
of all continents, and are particularly exposed at the surface in the large shields of Africa …

Abstract Integrated Hydrological Models (IHMs) dynamically couple surface and
groundwater processes across the unsaturated zone domain. IHMs are data intensive and …

Groundwater is a vital source of freshwater throughout the tropics enabling access to safe
water for domestic, agricultural and industrial purposes close to the point of demand. The …

Core Ideas AMMA‐CATCH is a long‐term critical zone observatory in West Africa. Four sites
sample the sharp ecoclimatic gradient characteristic of this region. Combined …

Specific yield is a key parameter for estimating water table depth in land surface models,
which can strongly modulate the interaction between soil moisture and groundwater and …

GRACE (Gravity Recovery and Climate Experiment) satellite data monitor large-scale
changes in total terrestrial water storage (ΔTWS), providing an invaluable tool where in situ …

Over the last few decades, important advances have been made in the development of
relevant hydrogeological conceptual models for crystalline aquifers, and notably for …

In Chad, hard-rock aquifers are the main source of drinking water for the population located
on basement areas. In these basement aquifers, and in particular those of the Guéra region …

Core Ideas We present a general overview of research performed at the Strengbach
catchment. Multidisciplinary studies are performed to understand export of water and …

A data-driven modelling approach was applied to quantify the potential groundwater yield
from weathered crystalline basement aquifers in West Africa, which are a strategic resource …
