Assessing heterogeneous groundwater systems: Geostatistical interpretation of well logging data for estimating essential hydrogeological parameters

In the framework of the Sustainable Development and Technologies project, this research focuses on employing an unsupervised learning approach to interpret well-log data, aiming to characterize the primary hydrostratigraphical units within the Quaternary aquifer system in the Debrecen area of Eastern Hungary.

Determination of the ammonia loss from croplands

Half of the applied fertilizers are not used globally and instead pollute the environment. Determining the degree of loss, which is crucial for prevention, is accomplished using models validated by measurements.

Hyperparameter inversion of well logs for the simultaneous estimation of volumetric and zone parameters

We present a new alternative for the joint inversion of well logs to predict the volumetric and zone parameters in reservoir rocks. Porosity, water saturation, shale content, kerogen and matrix volumes are simultaneously estimated with the tool response function constants with a hyperparameter estimation assisted inversion of open-hole well logs. We treat the zone parameters, i.e., the physical properties of rock matrix constituents, shale, kerogen, and pore-fluids, as well as some textural parameters, as hyperparameters and estimate them using genetic algorithm for the entire processing interval.

Book chapter on the possibilities of urban brownfield sites in the service of more liveable cities

In their study, they draw attention to the growing importance on the revitalization of brownfield areas, to reduce land extraction resulting from urbanization, and examine the possibilities of temporary usage, which is little used in the domestic context but forms the basis of many foreign developments, to improve urban liveability.

The river Nile in Miskolc, Hungary

Geophysicists and hydrogeologists from Miskolc and Sopron gave climate researchers a unique tool by mathematically supplementing the gaps in the Nile water level measurements – the very first surviving and uniquely long numerical observation.
