Investigating the causes of water scarcity in the gavkhoni basin through dynamic cellular automata models and landsat satellite imagery

Sustainable Futures
Water scarcity in Iran’s Gavkhoni Basin has intensified due to accelerated land-use change and ineffective water management. This study employs a spatially explicit Cellular Automata (CA) model to analyze drought-related transformations from 2010 to 2020
