Inundation Extent Mapping by Synthetic Aperture Radar: A Review

open access: yesRemote Sensing, 2019
Recent flood events have demonstrated a demand for satellite-based inundation mapping in near real-time (NRT). Simulating and forecasting flood extent is essential for risk mitigation. While numerical models are designed to provide such information, they

Mixed pixel analysis and assessment for flood mapping [PDF]

open access: yes, 2014
The most difficult operation in flood inundation mapping using optical flood images is to map the ‘wet’ areas where trees and houses are partly covered by water.

Voltage‐Reconfigurable Magneto‐Ionic Nanolayers in Dot Arrays for Probabilistic, Materials‐Engineered Security Primitives

open access: yesAdvanced Science, EarlyView.
A magneto‐ionic security‐by‐materials‐design strategy exploits voltage‐driven N3– migration in selectively contacted FeCoN dots, creating reconfigurable sub‐15 nm ferromagnetic sublayers with deterministic and/or probabilistic (single‐domain↔vortex) states, voltage‐tunable probabilities and fully stochastic orientation/chirality.

A novel hybrid framework of high-resolution flood susceptibility mapping in ungauged mountainous regions

open access: yesWeather and Climate Extremes
Flood susceptibility mapping in mountainous regions remains a critical tool for mitigating escalating flood risks in the context of climate change. However, its accuracy is constrained by data scarcity of flood inventory maps and uncertainties in flood ...

Flood Prediction and Mitigation in Data-Sparse Environments [PDF]

open access: yes, 2013
In the last three decades many sophisticated tools have been developed that can accurately predict the dynamics of flooding. However, due to the paucity of adequate infrastructure, this technological advancement did not benefit ungauged flood-prone ...

Automatic Extraction of Water Bodies from TerraSAR-X Data [PDF]

open access: yes, 2008
Medium resolution SAR satellite data have been widely used for water and flood mapping in recent years. Since the beginning of 2008 high resolution radar data with up to one meter pixel spacing of the TerraSAR-X satellite are operationally available. The
