New forestry regulations are being questioned for their effectiveness in managing debris after Cyclone Gabrielle, with concerns that large-scale clear-felling on vulnerable slopes may continue.

Soil's Silent Guests: 'Emerging Contaminants' In Crops Spark Worry

New study from 2005-2024 shows emerging contaminants in crops and soil. Find out what this means for your food and health.

Researchers found new, unmonitored chemicals in crops and soil over the last 19 years. This is a growing problem that needs more study.

Thousands of studies describe Rayleigh–Taylor instability, and most hydrogeological models acknowledge its importance in contaminant transport.

However, in studies of the Svystunova gully mine-water storage pond, I have not seen density explicitly accounted for — despite highly mineralized waters where this factor can fundamentally change plume behaviour.
By calculating solution density within the contamination halo, I demonstrated a real risk of gravity-driven sinking of the contamination plume to the base of the aquifer. This finding adds a critical dimension to impact assessment and is now documented as a standalone section in my ongoing report.

If you work with mine water, aquifers contamination, or long-term contamination modelling, this is a parameter worth revisiting.

🌊 Modeling a potential dam breach — and how panic spread beyond the real watershed

This project assessed the potential consequences of a dam failure at a mine-water impoundment in the Svystunova Gully.

🔹 Reconstructed the original pre-impoundment terrain from archival topographic maps.
🔹 Used Sentinel-based land-cover classification to assign variable Manning’s roughness coefficients.
🔹 Built a modern DEM including the dam structure and current flooded zone.
🔹 Simulated dam-break flood dynamics in GRASS GIS — frame by frame.
🔹 Produced a video visualization to help local communities understand real risks (and ignore fake ones).
🔹 The results were later featured in regional media and used in discussions about mine-water safety.
