An extended Gauss-Newton method for full-waveform inversion
(Society of Exploration Geophysicists, 2024-05)Full-waveform inversion (FWI) is a large-scale nonlinear ill-posed problem for which computationally expensive Newton-type methods can become trapped in undesirable local minima, particularly when the initial model lacks ... -
Full waveform inversion and Lagrange multipliers
(Oxford University Press on behalf of The Royal Astronomical Society, 2024-04-19)Full-waveform inversion (FWI) is an effective method for imaging subsurface properties using sparsely recorded data. It involves solving a wave propagation problem to estimate model parameters that accurately reproduce the ... -

Comparison of different techniques in determining groundwater levels trends in Türkiye
(John Wiley & Sons Ltd., 2024)Groundwater represents one of the largest resources of freshwater in the world. Thus, investigations of groundwater level variations due to climate change and increasing human activities are of great importance, especially ... -
Results of Atmospheric Electricity and Meteorological Observations, S. Kalinowski Geophysical Observatory at Świder, 2007–2010
(Institute of Geophysics, Polish Academy of Sciences, 2023-12-31)Atmospheric electricity yearbooks have not been published since 2007. This was the result of the start of operation of the automatic database in which atmospheric electricity measurement data are recorded with high time ... -
Assessment of meteorological, hydrological and groundwater drought in the Konya closed basin, Türkiye
(Springer, 2024-05-02)Water scarcity, and drought in particular, is a major challenge worldwide, causing direct and indirect negative effects on ecological systems and water resources, as well as social and economic aspects of life. Climate ... -
Modelling the impact of historical and future Land Use Land Cover changes on the hydrological response of an Ethiopian watershed
(Springer, 2024-01-10)Land Use Land Cover (LULC) is generally considered one of the key factors influencing the hydrological processes and sediment output in arid and semi-arid watersheds. Focusing on the Ethiopian Fincha watershed, the current ... -

Can sediments play a role in river flood risk mapping? Learning from selected European examples
(Springer Nature, 2023-09-28)Background: Climate change and increasing anthropogenic pressure are two of the major drivers of increasing extreme events like droughts and floods. To deal with the increasing number of flooding events hitting Europe in ... -
SWAT model-based quantification of the impact of land use land cover change on sediment yield in the Fincha watershed, Ethiopia
(Frontiers Media S.A., 2023-09-07)In recent years, Ethiopia is facing problems due to soil erosion, mainly because of the conversion of natural vegetation into cultivated land to answer to increasing human pressure. Such changes in coverage are fostering ... -
Sensitivity of the GEM Model to Different Descriptions of City Surface Parameters over Warsaw
(Institute of Geophysics, Polish Academy of Sciences, 2023)Over half of the world’s population lives in urban areas, even though urban agglomerations cover only 0.05% of the Earth’s surface. Urbanisation significantly modifies the surface level’s moisture, radiation balance, thermal ... -
