Evaluating the Interpretation Uncertainty From the Manual Streambank Delineation

River Research and Applications, Volume 42, Issue 2, Page 495-506, February 2026.
ABSTRACT Streambank delineation enables the development of two important parameters: streambank position and channel width. For older aerial images that cannot be easily processed by automatic methods, manual interpretation of streambanks is a necessary task.

Flow History Effects on River Bifurcation Dynamics in a Himalayan River

Water Resources Research, Volume 62, Issue 2, February 2026.
Abstract Dynamic gravel bed rivers experience frequent changes in channel position and flow distribution between branches, which can alter the location and extent of flooding. Changes in flow routing can significantly impact livelihoods, habitats and infrastructure in adjacent floodplains. Here, we test whether variations in seasonal discharge patterns

Enhancing flood inundation mapping technique using Landsat-based remote sensing and 2D hydrodynamic modeling: a case study of the Bihar flood caused by the Koshi embankment breach

Frontiers in Remote Sensing
Floods have become more unpredictable and erratic due to the influence of extreme hydroclimatic events. Therefore, obtaining near-real-time, accurate flood inundation maps for such events is essential for effective flood emergency response, which can be ...

Integrating SWOT With Multi‐Source Satellite Observations for Near‐Daily Reservoir Water Level Monitoring

Water Resources Research, Volume 62, Issue 2, February 2026.
Abstract Reservoirs play a crucial role in global water resource management. Monitoring reservoir hydrologic dynamics is critical for assessing climate variability and anthropogenic regulation. However, traditional satellite altimetry faces multiple challenges hindering high frequency and accuracy water level monitoring.

Expansion of Exotic Mangroves Sonneratia apetala in China Since Start of the SDGs

Earth's Future, Volume 14, Issue 2, February 2026.
Abstract Since the Sustainable Development Goals (SDGs) came into effect in 2016, mangroves have received unprecedented attention for carbon sequestration capacity. In China, previous studies focused on the total area of mangroves using remote sensing technique, neglecting expansion of the exotic mangrove species Sonneratia apetala, even when it is ...

Delimitação de áreas inundáveis a partir de Modified Normalized Difference Water Index (MNDWI) no Município de Esteio (RS, Brasil)

Pesquisas em Geociências, 2017
Uma das possibilidades de análise a partir de imagens de satélite é a variação espacial e temporal de comportamento de áreas inundáveis. Entre os índices desenvolvidos para análise de recursos hídricos, se destaca o Modified Normalized Difference Water Index (MNDWI), elaborado com o intuito de ressaltar áreas inundáveis com um maior poder de ...

A Generalized Data‐Driven Shoreline Model at the Regional Scale

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 1, February 2026.
Abstract Shoreline models underpin long‐term coastal planning and hazard mitigation but are often limited by site‐specific calibration and simplified process representations. While machine learning (ML) approaches have recently matched or exceeded the skill of traditional models in deterministic shoreline forecasting, they have yet to demonstrate ...
