Flood Detection in Urban Areas Using Satellite Imagery and Machine Learning

Abstract: Urban flooding poses risks to the safety of drivers and pedestrians, and damages infrastructures and lifelines. It is important to accommodate cities and local agencies with enhanced rapid flood detection skills and tools to better understand how much flooding a region may experience at a certain period of time. This results in flood management orders being announced in a timely manner, allowing residents and drivers to preemptively avoid flooded areas. This research combines information received from ground o… Show more

“…The LSTM algorithm has provided the best flood level predictions. Tanim et al [ 44 ] put forward an unsupervised Machine Learning approach based on a combination of the Change Detection method, the Otsu algorithm, and fuzzy rules. This approach was tested on flood images captured by the ESA’s “Sentinel 1” satellite and has proved better classification performance when compared to the Random Forest (RF) algorithm, Support Vector Machines (SVM), and the Maximum Likelihood Classifier (MLC).…”

“…The most common ML classification methods are Artificial Neural Networks (ANN), k-Nearest Neighbors (kNN), Decision Trees (DT), Support Vector Machines (SVM), Random Forest (RF) (Hassan et al, 2020;Antzoulatos et al, 2022;Tanim et al, 2022). The most common ML methods found in this review are Support Vector Machine and Random Forest models.…”

“…The tools for thermal noise removal and border noise removal are optional steps, the last one used when dealing with subset images, cropped from bigger data. Thermal noise is background energy caused by the microscopic motion of electrons due to temperature and can also be removed in pre-processing (Phan et al, 2019;Tanim et al, 2022).…”
