Subjects: Civil and Environmental Engineering, Earth Sciences, Engineering, Environmental Engineering, Environmental Sciences, Geology, Geomorphology, Geotechnical Engineering, Glaciology, Hydraulic Engineering, Hydrology, Physical Sciences and Mathematics, Risk Analysis, Sedimentology, Social and Behavioral Sciences
Erosion can fundamentally alter landslide acceleration through the produced momentum. However, existing analytical landslide velocity models do not account for the energy dissipation associated with erosion-induced system acceleration. Here, I present a novel, complete dynamical velocity model for erosive landslides that incorporates two intrinsically coupled mechanically essential processes: [...]
Leveraging satellite data and machine learning to quantify rooftop rainwater harvesting reliability and tank requirements for schools and health care facilities in Uganda
Published: 2026-10-17
Subjects: Civil and Environmental Engineering, Earth Sciences, Environmental Engineering, Environmental Sciences, Geography, Hydrology, Remote Sensing, Water Resource Management
Many schools and health facilities in Uganda lack a reliable water supply, yet most have roofs that could collect rain. For 41,592 facilities (32,881 schools and 8,711 health facilities), we estimated how much water their roofs can supply, how large a tank each one needs, and how often that supply fails. Roof areas came from AI-derived building footprints (Google Open Buildings v3) and daily [...]
A Community-Oriented Flood Map Visualization and Evaluation Framework

Subjects: Civil and Environmental Engineering, Computer Engineering, Computer Sciences, Engineering, Hydraulic Engineering, Hydrology, Software Engineering
Flood inundation maps are essential for preparedness, response, and long‐term risk mitigation, yet many existing visualization platforms remain limited by rigid data structures and region‐specific workflows.

GeONet: Geometry-Encoded Operator Network for Predicting Flow in Heterogeneous Porous Media
Published: 2026-10-15
Subjects: Civil and Environmental Engineering, Computer Engineering, Earth Sciences, Engineering, Environmental Sciences, Mathematics, Physical Sciences and Mathematics
Rapid prediction of pressure-driven flow in microfluidic porous-media analogs is important for experimental design, tracer-test interpretation, and real-time digital-twin development for subsurface energy and critical mineral science applications. High-fidelity numerical simulators resolve geometry-controlled flow in heterogeneous pore networks, but their computational cost limits repeated [...]

Subjects: Civil and Environmental Engineering, Earth Sciences, Environmental Sciences, Other Physical Sciences and Mathematics, Physics, Risk Analysis
On 24 September 2026, a moderate earthquake occurred in southeastern Türkiye near the Hilvan–Karaköprü sector of Şanlıurfa Province. The U.S. Geological Survey (USGS) reported M 5.3 at 37.4736°N, 38.8612°E and 10 km depth, whereas the Disaster and Emergency Management Authority of Türkiye (AFAD) issued a rapid Mw 5.4 solution at a shallower and approximately 5.9 km displaced hypocenter. We [...]
Intensifying salinity intrusion in the Barataria Basin, 2010 to 2026: a coastward gradient in the rate of change
Published: 2026-09-24
Subjects: Civil and Environmental Engineering, Earth Sciences, Environmental Sciences, Oceanography and Atmospheric Sciences and Meteorology
The Barataria Basin, a shallow microtidal estuary in coastal Louisiana, has lost a substantial part of its wetland area and is exposed to increasing salinity intrusion as the Mississippi River remains leveed and relative sea level rises. Salinity conditions in this basin have been described, but whether the rate at which salinity changes varies spatially across the basin has not yet been [...]
A Quantitative Feasibility Model for Singapore Waste-to-Energy Ash as a Zeolitic Material Feedstock
Published: 2026-08-28
Subjects: Civil and Environmental Engineering, Engineering, Engineering Science and Materials, Environmental Engineering, Materials Science and Engineering, Other Materials Science and Engineering
In Singapore’s waste management system, waste-to-energy ash is a major by-product but is viewed as a residue to be managed rather than a material resource. This paper examines whether Singapore waste-to-energy ash could be used as a feedstock for zeolitic material synthesis, when assessed through a quantitative feasibility model rather than a descriptive review. In this study a mathematical [...]
Adalar at the Eastern Marmara Seismic Gap: The August 2026 Earthquake Cluster and Its Implications for Seismic Hazard near Istanbul

Identifying Lead Components in Uganda’s Water Infrastructure Supply: A Supply Chain Mapping and Intervention-Identifying Analysis
Published: 2026-07-23
Subjects: Civil and Environmental Engineering
Lead (Pb) exposure through drinking water causes a substantive preventable disease burden. The primary source of Pb in drinking water is through Pb-containing infrastructure, including leaded-brass fittings, galvanized iron/steel pipes, and some plastics. As the source of Pb through drinking water is widely known, its prevention through a supply chain intervention is possible. This is true in [...]
