Lateral sediment sources and knickzones as controls on spatio-temporal variations of sediment transport in an Alpine river [PDF]

, 2013
Modern mixed alluvial-bedrock channels in mountainous areas provide natural laboratories for understanding the time scales at which coarse-grained material has been entrained and transported from their sources to the adjacent sedimentary sink, where ...

Immune Evasion of Helicobacter pylori and Extra‐Gastric Cancer Risk

Journal of Gastroenterology and Hepatology, EarlyView.
ABSTRACT Helicobacter pylori (H. pylori) is a group 1 gastric carcinogen that plays a significant role in extra‐gastric digestive system cancers. H. pylori disrupts host cell homeostasis through expression of virulence factors leading to immune evasion as well as persistent gastric mucosal colonization. H. pylori infection has been shown to play a role

Data Resolution and Model Complexity in Pluvial Flood Risk Assessment: Insights and Trade‐Offs

Journal of Flood Risk Management, Volume 19, Issue 2, June 2026.
ABSTRACT The increasing severity and frequency of urban pluvial floods has prompted numerous research studies on pluvial flood risk assessment. However, the literature reveals significant variability in the data resolutions and model types employed.

Flood Mitigation Strategies: Integrating Hydrologic Engineering Systems- River Analysis Systems for Effective Management of Paremang Watershed

Jurnal Sylva Lestari
The Hydrologic Engineering System-River Analysis System (HEC-RAS) model is a model that can display water surface cross-sections in both 1D and 2D forms. That way, HEC-RAS can predict the amount of peak discharge that results in flooding. This study aims

Developing Guidelines for Two-Dimensional Model Review and Acceptance [PDF]

, 2018
Two independent modelers ran two hydraulic models, SRH-2D and HEC-RAS 2D. The models were applied to the Lakina River (MP 44 McCarthy Road) and to Quartz Creek (MP 0.7 Quartz Creek Road), which approximately represent straight and bend flow conditions ...

Assessing the Dynamic Resilience of Urban Road System: A Case Study of Xiamen City, China

Journal of Flood Risk Management, Volume 19, Issue 2, June 2026.
ABSTRACT Urban road system resilience is critical for managing extreme flood events, yet existing assessments predominantly focus on static indicators that capture inherent system capacity rather than dynamic responses to disturbances. This study proposes a dynamic resilience analysis framework that tracks urban road system performance under ...

Building‐Scale Flood Hazard Modelling for Risk Assessment of Cultural Heritage

Journal of Flood Risk Management, Volume 19, Issue 2, June 2026.
ABSTRACT Flooding is among the most frequent natural hazards threatening cultural heritage sites, yet current flood hazard studies often operate at urban or regional scales. While building‐scale damage models exist, they generally rely on flood depth inputs from large‐scale inundation models, inputs that may fail to capture the internal complexity of ...

FLOOD INUNDATION MAPPING BY GIS AND A HYDRAULIC MODEL (HEC RAS): A CASE STUDY OF AKARCAY BOLVADIN SUBBASIN, IN TURKEY [PDF]

Acta Geobalcanica, 2016
In this study, it is aimed to constitute flood inundation maps for Akarcay Bolvadin Subbasin. Topographic data of study area is defined for hydraulic model by sectioning along the river on Digital Elevation Model (DEM) which is created by ArcGIS, a ...
