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 ...

Linking Stress Drop and Slip Heterogeneity to Assess Source Rupture Directivity for Earthquakes in Central Italy

Terra Nova, Volume 38, Issue 3, Page 163-172, June 2026.
ABSTRACT In this study, we examine the relationship between Brune stress drop and fault slip where the stress drop is estimated using the Empirical Green's Function (EGF) method and slip distribution is derived from seismic and geodetic data inversion.

The Staggered SAR concept: Imaging a wide continuous swath with high resolution

, 2013
Staggered SAR is an innovative synthetic aperture radar (SAR) concept, based on the continuous variation of the pulse repetition interval (PRI). This concept allows high-resolution imaging of a wide continuous swath without the need for a long antenna ...

Land Subsidence Susceptibility Mapping in Semi‐Arid Regions Using PS‐InSAR and Tree‐Based Ensemble Machine Learning: A Case Study From Çumra, Türkiye

Transactions in GIS, Volume 30, Issue 4, June 2026.
ABSTRACT Land subsidence is an increasing environmental hazard in semi‐arid agricultural basins where intensive groundwater abstraction, compressible geological units, and expanding land‐use pressures interact. This study presents a PS‐InSAR and machine‐learning‐based framework for land subsidence susceptibility mapping in the Çumra District of the ...

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‐

Ultra Wide Swath Imaging With Multi-Channel SAR Systems

, 2008
Multi-channel radar systems allow for overcoming the inherent limitation of conventional synthetic aperture radar (SAR). An example is the combination of digital beamforming on receive in elevation with multi-aperture SAR signal reconstruction in azimuth

Feasibility Mapping of L‐Band InSAR for SWE Retrievals Across the Western United States

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract Mountain snowpacks provide vital water resources for communities in the western U.S. (WUS), but high spatial variability challenges accurate measurement of snow water equivalent (SWE) from remote sensing platforms. Studies using repeat airborne L‐band (∼25 cm wavelength) Interferometric Synthetic Aperture Radar (InSAR) have demonstrated ...

Non‐Linear Morphodynamic Response of Deltas to Extreme Events

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract Deltas, the interface between riverine and coastal systems, host ∼500 million people and function as crucial ecological nexuses. The magnitude and frequency of extreme floods are projected to intensify as climate changes, yet the potential impacts on delta morphodynamics remain poorly understood.

Snow Depth on Arctic Sea Ice Retrieval Using a Synergy of Sentinel‐3's Active and Passive Microwave Instruments

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract Snow depth remains one of the largest sources of uncertainty in satellite‐derived sea ice thickness (SIT). Here, we introduce the novel Nadir Radiometer and Radar Synergy (NaRRS) method that combines data from Sentinel‐3's Microwave Radiometer (MWR) and Synthetic Aperture Radar Altimeter (SRAL) to retrieve Arctic snow depth on sea ice.
