Cross-modal distillation for flood extent mapping
Environmental Data Science, 2023 Abstract The increasing intensity and frequency of floods is one of the many consequences of our changing climate. In this work, we explore ML techniques that improve the flood detection module of an operational early flood warning system. Our method exploits an unlabeled dataset of paired multi-spectral and synthetic aperture radar (SAR) imagery to

Advanced Functional Materials, EarlyView.This work presents a closed‐loop optimization workflow integrating CatBot, an automated synthesis and testing system, to discover NiMo hydrogen‐evolution catalysts. CatBot synthesised and evaluated 228 unique samples, identifying the best performing catalysts for transfer to nickel‐foam electrodes. The best candidate is highly active, reaching 1 Acm−2${

Pre‐flood inundation mapping for flood early warning [PDF]
Journal of Flood Risk Management, 2011 AbstractIn this study the results of two rainfall‐run‐off simulations were used as input into a MIKE11 GIS and hydrological modelling process for flood inundation mapping based on the flood event (27 September to 8 October 2000) in Malaysia of the Langat River Basin area.

FLOOD INUNDATION MAPPING USING SPATIAL TECHNIQUES
, 2014 This paper discusses the role of various spatial techniques available for extracting the floodinundation map for river basins. Flood inundation mapping is a vital component for appropriate landuse planning in flood-prone areas.

Advanced Functional Materials, EarlyView.A lead‐free tin‐based hybrid perovskite is designed in which stereochemically active lone‐pair electrons on tin distort the crystal lattice and break its symmetry. Blended into a flexible polymer, the material converts pressure into electricity at milliwatt‐scale power density and continues working far below freezing, powering a commercial wristwatch ...

Flooding-Driven Greenhouse Gas Emissions From Global Upland Croplands. [PDF]
Adv Sci (Weinh)Temporary flooding of upland croplands releases nitrous oxide, carbon dioxide, and methane. Field measurements combined with a global literature synthesis yield a global estimate of 63.3 teragrams of carbon dioxide equivalent per year for diffusive emissions from flooded upland croplands.

Flood risk mapping at European scale
Water Science and Technology, 2007 The aim of this article is to illustrate a framework for flood risk mapping at pan-European scale produced by the Weather-Driven Natural Hazards (WDNH) action of the EC-JRC-IES. Early results are presented in the form of flood risk index maps. We assess several flood risk factors that contribute to the occurrence of flood disasters.

Strategies for the automatic mapping of flooded areas and other water bodies from high resolution TerraSAR-X data [PDF]
, 2009 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
