Published: July 1, 2024

Flash floods, rapid and devastating inundations of water, are increasingly linked to the intensifying effects climate change, posing significant challenges for both vulnerable communities sustainable environmental management. The primary goal this research is investigate predict a Flood Susceptibility Map (FSM) Ibaraki prefecture in Japan. This utilizes Random Forest (RF) regression model GIS, incorporating 11 variables (involving elevation, slope, aspect, distance stream, river, road, land cover, topographic wetness index, stream power plan profile curvature), alongside dataset comprising 224 instances flooded non-flooded locations. data was randomly classified into 70 % training set development, with remaining 30 used validation through Receiver Operating Characteristics (ROC) curve analysis. resulting map indicated that approximately two-thirds as exhibiting low very flood susceptibility, while one-fifth region categorized high susceptibility. Furthermore, RF achieved noteworthy an area under ROC 99.56 %. Ultimately, FSM serves crucial tool policymakers guiding appropriate spatial planning mitigation strategies.

Meteorological drought assessment in northern Bangladesh: A machine learning-based approach considering remote sensing indices

Ecological Indicators, Journal Year: 2023, Volume and Issue: 157, P. 111233 - 111233

Published: Nov. 14, 2023

Meteorological drought, driven by inadequate precipitation, has significant repercussions for water resources, agriculture, and human well-being. This study conducted an extensive assessment of meteorological drought in northern Bangladesh, employing remote sensing indices machine learning techniques. The main aim was to evaluate occurrences Bangladesh from 2010 2019, utilizing seven parameters a model. Utilizing Random Forest (RF) model, this employed the Standardized Precipitation Index (SPI) as dependent variable independent variables. Through methodology, assessed significance these generated model integrated them, culminating creation distribution map spanning 2019. approach offers novel insights probing interplay collective impacts indices, shedding light on previously unexplored aspects regional patterns Bangladesh. major findings showed that precipitation strongly influenced both short-term long-term episodes. Moreover, land surface-related such Evapotranspiration (ET) Normalized Difference Water (NDWI), exhibited more pronounced impact occurrences, while vegetation-related like Multi-band Drought (NMDI) Vegetation (NDVI) demonstrated greater influence over events. During timeframe, Rajshahi division experienced frequent extreme severe Moderate droughts abnormally dry conditions were widespread. Barind tract area consistently faced moderate droughts, with exceptions 2011, 2014, On average, 5% region had than 12% during decade.

Estimating the salinity of soil along coast south-western Bangladesh is focus this study. Thirteen indicators were computed using Landsat OLI images, and 241 samples gathered from secondary sources. In research, partial least-squares regression was used to estimate salinity. Soil zones then divided into five classes based on Jenks natural breaks. There a strong relationship between several indices, including B2 (Blue band), B5 (Near-Infrared SI_1 (Salinity index 1), SI_2 2). The correlation particularly high, hovering around 0.92. majority other factors, however, have negative or barely positive −0.260 0.032.
