Early wildfire detection and prediction systems based on machine learning have typically relied on a single type of data, either meteorological data or satellite imagery, limiting their accu…
CSEF · 2026
Environmental Engineering (Senior Division)
For 50 years, Great Hammerhead populations have been declining. These are vital keystone species in our oceans; They help control sick fish populations and maintain ecosystem balance. As the…
CSEF · 2026
Environmental Engineering (Track 2) (Senior Division) Honorable_mention Award
Leafy vegetables like Malabar spinach require optimal soil moisture (SM) to ensure steady physiological activity, improved nutrient uptake, and higher leaf yield. Too much or too little wate…
ISEF · 2026
Environmental Engineering
The purpose of this research was to engineer and deploy a method and device that could selectively suppress cyanobacteria and cyanotoxins while improving the overall ecosystem and lake healt…
ISEF · 2026
Environmental Engineering Third Award
Urban flooding is escalating into a critical global challenge, driven by the inability of conventional drainage inlets to handle increasing rainfall intensities due to rapid urbanization and…
CSEF · 2026
Environmental Engineering (Track 2) (Junior Division) Fourth Award
Approximately 70% of global freshwater is used for agricultural irrigation, even though 40% of agricultural freshwater is wasted annually, making water conservation a critical environmental…
ISEF · 2026
Environmental Engineering
Severe eutrophication causes hypoxic “dead zones” (e.g., the Gulf of Mexico). The mass death of marine life accelerates oxygen depletion, creating a vicious cycle. Conventional restoring met…
