Assessing Relative Gully Morphometric Change After Extreme Rainfall Events: A UAV‐Based GIS Framework Applied to the 2024 DANA in Southern Spain

open access: yesTransactions in GIS, Volume 30, Issue 1, February 2026.
ABSTRACT Climate change is intensifying the frequency and impact of extreme weather events, particularly in vulnerable Mediterranean environments. This study investigates relative morphometric changes within a gully system in the Guadalmedina River basin (Málaga, southern Spain) triggered by the 2024 DANA (Depresión Aislada en Niveles Altos), a high ...

GeoSimulations in 4D: Multi‐Dimensional Agent‐Based Model for Representing Dynamics of Southern Resident Killer Whales

open access: yesTransactions in GIS, Volume 29, Issue 7, November 2025.
ABSTRACT The Southern Resident killer whales (SRKW) are an endangered species that occupy marine environments on the west coast of North America, including the Salish Sea. Representing marine species in this environment can be achieved by multidimensional space–time simulation modeling that provides more information about locations and behaviors for ...
