Fast forward

Article Abstract:

High-speed railways are advancing rapidly towards an integrated system that will cover most of Western Europe, in an effort to solve congestion and pollution problems of airways and automotive transportation. High-speed electric trains are free of emissions, take up much less land than roads or railways and are quieter than conventional trains. Some believe their expense will leave other links in the transport system financially neglected. Britain lags several years behind in high-speed rail plans, which may prove embarrassing when France completes its Train a Grand Vitesse (TGV) link to the Channel Tunnel.

Managing river environments: the way forward

Article Abstract:

Geomorphology is becoming an important element in river management and flood control. Traditional river engineering techniques, such as channelization and resectioning, have often led to bank erosion and ecosystem damage. Restoration of meandering channels, modified excavation procedures, and proper management of river corridors are all geomorphologically-based answers to river engineering problems. Other improved techniques include using willow stakes to protect eroding channels and planting shrubs to prevent bank erosion.

Unblocking an inland artery

Article Abstract:

Germany's Main-Danube canal is scheduled to open on Sep 25, 1992. The new canal will be part of a larger Rhine-Main-Danube waterway that will allow ships to travel from the North Sea to the Black Sea. Although founded in 1921, the Rhine-Main-Donau Co (RMD) did not begin serious work on the huge project until the 1960s. Work has gone forward since then despite considerable opposition by environmentalists. RMD hopes that the production of hydroelectric power will enable the project to pay for itself by 2050.
