No Time for Dithering

Katrin Brummermann

Those who take an interest in sustainability and environment and climate protection will find something to interest them in the technical articles that are published in this edition of GeoResources Journal. Moreover, taking a look ‘outside the professional box’ can provide inspiration for creative thought and action.

Remediation of contaminated Sediments in Surface Waters using active Geocomposites

Stefan Niewerth and Markus Wilke

The innovative method of active sediment capping with active geocomposites enables environmentally protective, low-risk and efficient remediation of surface waters containing polluted sediments. This article explains active geocomposites and compares the remediation method of active sediment capping, which has already been proven in North America and Scandinavia in particular, with conventional methods. The practicality of the system is illustrated by the example of a remediation in Sydney in Australia with significant contamination of the sediments with PAHs and TPHs.

Sustainable Climate Protection in Hydraulic ­Engineering with innovative River Mattresses for Bank Protection

Michael Arndt and Francesco Masola

Innovative river mattresses are known to contribute to sustainable climate protection (up to –82 % CO2), to saving of natural resources and to cost reduction (up to –73 % layer thickness) in hydraulic engineering. This article presents the product development and the intended sustainable impacts.

Rockfall Protection on Traffic Routes

Eberhard Gröner

Many traffic routes in the area of the Alps and in the mountain regions of central European require reliable and economical rockfall protection. Flexible systems with nets made of high-tensile steel wire have demonstrated their effectiveness in many projects in recent years.

Pipe Jacking under special ­Conditions: Crossing below a Set of Railtracks and above an Underground Railway Tunnel

Dennis Edelhoff

The renaturation of the river Emscher included a pipe jacking operation that had to cross under a sensitive set of railtracks and then immediately afterwards pass above an underground rail tunnel pipe. The team involved in planning and executing the project had to overcome particular challenges to ensure that the existing infrastructure was well protected throughout the operation.

Increasing social Acceptance in the Management of Tailings Storage Facilities (TSF)

Tobias Rudolph and Peter Goerke-Mallet

Ensuring social acceptance for mining projects, and especially when it comes to settling ponds for mine tailings, is a huge challenge. Modern geomonitoring integrates data obtained from orbiting satellites, from overflying aircraft and from the surface of the ground, as well as from below it, to create a transparent and space and time-referenced process understanding. Geomonitoring technology is therefore an important tool for risk management and communication over the course of the mining lifecycle.

NEXT – New Exploration Technologies Project fulfils Expectations

Juha Kaija, Vesa Nykänen and Torsten Gorka

European Union Horizon 2020 project NEXT was created to develop new geomodels, novel sensitive exploration technologies and data analysis methods which together are fast, cost-effective, environmentally safe and, potentially more acceptable to local actors and communities.
