Flood Hazard Mapping in a Data‐Scarce Urban Watershed Using Analytical Hierarchy Process and Fuzzy Logic: A Case Study of Cuttack, India

Journal of Flood Risk Management, Volume 19, Issue 2, June 2026.
ABSTRACT Floods are among the most frequent and damaging natural hazards in India, particularly affecting low‐lying urban areas in the eastern regions such as Cuttack, Odisha. This study aims to develop a flood hazard susceptibility map for the Cuttack district in Odisha, India, using a combined Analytical Hierarchy Process (AHP) and fuzzy logic ...

Resilience in the Face of Recurring Floods: Insights From the Riverine Island Communities in Bangladesh

Journal of Flood Risk Management, Volume 19, Issue 2, June 2026.
ABSTRACT Community resilience is increasingly central to climate adaptation policy, yet household‐level evidence from riverine island (char) settings remains limited. This study assessed household flood resilience in riverine island communities of northern Bangladesh and developed a context‐specific Flood Resilience Index (FRI) using targeted ...

Edge-aware nonlinear diffusion-driven regularization model for despeckling synthetic aperture radar images

EURASIP Journal on Image and Video Processing
Speckle noise corrupts synthetic aperture radar (SAR) images and limits their applications in sensitive scientific and engineering fields. This challenge has attracted several scholars because of the wide demand of SAR images in forestry, oceanography ...

Do Storm Characteristics Affect Urban Flood and Its Control? Assessment of Urban Drainage System Considering Rainfall Spatial Variability

Journal of Flood Risk Management, Volume 19, Issue 2, June 2026.
ABSTRACT The interaction between rainfall spatial–temporal variability and watershed response has been extensively studied in recent decades. Due to the influence of spatiotemporal non‐uniformity and variability in urban rainfall processes, the urban drainage system can exhibit different capabilities of handling flood risk.

An Upper Bound on Carbon Emissions of Drained Peat Soil Grasslands From Satellite Radar Interferometry

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract Drained and cultivated grasslands on peat soils behave as a significant source of greenhouse gasses by oxidation. However, the lack of empirical estimates of carbon losses from peatlands with adequate spatial and temporal resolution has forced researchers to rely on process‐based model approximations to make quantitative, regional‐ or national‐

GRENet: GNSS‐Enhanced Radar Extrapolation Network for Precipitation Nowcasting

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract Accurate precipitation nowcasting is one of the most challenging tasks in atmospheric sciences. The current methods of nowcasting primarily rely on inferring precipitation from radar reflectivity, which inevitably leads to uncertainties in forecasts due to the limitations of single radar data in capturing the detailed initial conditions of ...
