Wildfire is a major concern worldwide and particularly in Australia. The 2019–2020 wildfires Australia became historically significant as they were widespread extremely severe. Linking climate vegetation settings to can provide insightful information for wildfire prediction, help better understand behavior the future. goal of this research was examine relationship between recent wildfires, various hydroclimatological variables, satellite-retrieved indices. analyses performed here show...

The Aculeo lagoon basin is facing a severe drought, resulting in restriction of water usage solely for domestic purposes, and legal sanctions those who use grass irrigation. To identify illegal resources, this project evaluates the health lawns during dry season, using multi-spectral multitemporal satellite data. Soil indices, including NDVI, EVI, GNDVI, SAVI, NDMI, MSI, BSI, were derived between October 2021 April 2022. Cluster analysis was performed to evaluate statistical distribution...

Several studies have focused on why the Aculeo Lagoon in central Chile disappeared, with a recent one concluding that lack of precipitation was main cause, bringing tremendous political consequences as it supported argument government is not responsible for this environmental, economic, and social disaster. In study, we evaluated detail socio-economic history watershed, past climate its effects lagoon’s water levels (including recycling effects), anthropogenic modifications to balance,...

One of the most recurring discussions among people is real impact global warming and human activity on our natural resources. It hard to identify quantify generated by each one. Laguna de Aculeo located in Paine city, Chile. was one attractive beautiful places visit summer. Today, has been completely drying up. This research evaluates weather hydrologic values registered government water levels stations. The purpose evaluate if there a change precipitation, temperature, level trend. analysis...

This study leverages a Random Forest model to predict flood hazard in Arizona, New Mexico, Colorado, and Utah, focusing on enhancing sustainability management. Utilizing the National Flood Hazard Layer (NFHL), an intricate map of Arizona was generated, with Classification algorithm assessing for each grid cell. Weather variable predictions from TerraClimate were integrated NFHL classifications Digital Elevation Model (DEM) analyses, providing comprehensive understanding dynamics. The...

The Chilean summer of 2017 was the worst wildfire season by far. Hundreds wildfires burned a total more than half million hectares forested land (native forests and forest plantations). A significant portion area occupied Hualo (Nothofagus glauca (Phil.) Krasser), native species widely distributed in central Chile. Using water-drop-penetration-time method, post-fire water repellency evaluated at different depths (on mineral soil surface 5 mm below it) for stand. Comparative data were...

Abstract Access to accurate spatio-temporal groundwater level data is crucial for sustainable water management in Chile. Despite this importance, a lack of unified, quality-controlled datasets have hindered large-scale studies. Our objective was establish comprehensive, reliable nationwide dataset. We curated over 120,000 records from 640 wells, spanning 1970-2021, provided by the General Water Resources Directorate. One notable enhancement our dataset incorporation elevation data. This...
