A lightweight monocular perception framework generates high‐fidelity depth maps and integrates YOLOv8 detection to estimate object‐wise distances from a single RGB image. Evaluated on KITTI and the proposed D‐Far250 dataset, the system demonstrates accurate long‐range perception up to 250 m while maintaining real‐time performance, enabling scalable ...

The Deadman River watershed (British Columbia, Canada) was severely impacted by the Sparks Lake Fire in 2021. Timelapse photogrammetry reveals sharp post‐fire channel widening and increase in migration rate. Through multispectral remote‐sensing analysis, these morphodynamic changes are related to burn severity affecting the watershed.

High‐resolution satellite imagery and UAV data enabled detailed morphometric parameter calculation, meander classification and multi‐epoch change detection for the Atrak River's meandering channel. Our results reveal rapid, episodic migration and a nearly tenfold surge in bank erosion triggered by the 2019 extreme flood, with persistent instability at ...

Rapid Hydraulic Modelling in Post‐Wildfire Channels Using a Tiered Framework
A three‐tier hydraulic modelling framework enables rapid, safe calibration of post‐wildfire channel models using remote sensing and limited field data. Tested on two contrasting burned Colorado watersheds, discharge and salt tracer velocity measurements alone captured most of the achievable model accuracy, with detailed bathymetric survey adding little

Traffic Flow Data Collection Methods During Wildfire Evacuation
ABSTRACT With climate change and urbanisation increasing wildfire risk in the wildland–urban interface (WUI), enhancing community evacuation preparedness is crucial. This study evaluates different data collection methods for measuring traffic flows during a community wildfire evacuation drill in Roxborough Park, Colorado, in June 2024.
