Technical note: Biases and uncertainties in estimating water table depths using high-resolution SPOT / Pléiades images of traditional livestock watering practices in the Sahel

Farida Boubé Dobi, Guillaume Favreau, Yahaya Nazoumou, Alexandre Zoppis et autres

Abstract. Groundwater resources in Africa remain largely understudied despite their crucial role in sustaining socio-economic activities, rural livelihoods and climate resilience. This knowledge gap is mainly due to the scarcity of long-term, reliable and spatially extensive in situ monitoring data. In this …

Technical note: Operational calibration and performance improvement for a 1D hydrodynamic model in a data-scarce coastal area

Francisco Rodrigues do Amaral, Benoı̂t Camenen, Tin Nguyen Trung, Tran Anh Tu et autres

In this study, we address the challenges posed by data scarcity in hydrodynamic modeling in one of the most vulnerable coastal zones in the world – the Saigon–Dongnai tidal river system in southern Vietnam. We investigate calibration strategies for a 1D hydrodynamic …

Mapping the groundwater depth in Africa at high resolution (1 km²) based on the Parflow model and machine learning

Thierry Pellarin, Alexandre Zoppis, Pedro Arboleda, Jean‐Martial Cohard

Groundwater depth is the result of a balance between climatic conditions (rainfall, temperature, radiation, etc.), topography (slope and proximity of a river), land use, soil and subsoil characteristics (hydrodynamic parameters), and potential exploitation by man.In order to better understand the evolution of …

An explicit representation of river-floodplains relationships in the integrated hydrological - land surface model CLM-PARFLOW

Pedro Arboleda, Jean‐Martial Cohard, Basile Hector, Thierry Pellarin

Floodplains, a type of wetland regularly flooded by large rivers, are important hydrological objects to document and understand. They are places where the hydrological risk can be highly damageable, and where the high frequency of saturated soil moisture conditions due to flooding …

PrISM at Operational Scale: Monitoring Irrigation District Water Use during Droughts

Giovanni Paolini, Maria‐José Escorihuela, Joaquim Bellvert, Olivier Merlin et autres

Efficient water management strategies are of utmost importance in drought-prone regions, given the fundamental role irrigation plays in avoiding yield losses and food shortages. Traditional methodologies for estimating irrigation amounts face limitations in terms of overall precision and operational scalability. This study …
