The Role of Ammonia in the Distribution of Volatiles in the Primordial Hydrosphere of Europa

The Planetary Science Journal
The presence of a hydrosphere on Europa raises questions about its habitability, and studies of its volatile inventory can provide insight into its formation process. Different scenarios suggest that Europa's volatiles could be derived from cometary ices

Development of a Distributed Physics‐Informed Deep Learning Hydrological Model for Data‐Scarce Regions

Water Resources Research
Climate change has exacerbated water stress and water‐related disasters, necessitating more precise streamflow simulations. However, in the majority of global regions, a deficiency of streamflow data constitutes a significant constraint on modeling ...

Hydrology in the Age of Artificial Intelligence: From Fragmentation to Coherent Terrestrial Hydrosphere Science

Water Resources Research
The rapid rise of machine learning (ML) in hydrology has prompted debate about the discipline's scientific relevance. While ML often outperforms traditional models in streamflow prediction, we argue that this reflects a deeper limitation: persistent ...

A semi-analytical model of the velocity profile for a conduit-multilayer matrix system

Journal of Rock Mechanics and Geotechnical Engineering
The flow field characteristics of the conduit-matrix system (CMS) have consistently been a primary area of interest to researchers. However, under the long-term influence of water flow, the hydraulic conductivity of the matrix surrounding the conduit ...
