Landslides along the Three Gorges Dam

The world's largest dam project is set to bring enormous benefits to the Chinese economy. But there's a potential side-effect of altering the natural system - the likelihood that more geological disasters such as landslides will occur in the area. Find out why in this clip from 2008.

Three Gorges Dam: hydro-electricity as a choice

China has built the massive Three Gorges Dam to provide hydro-electricity. The dam provides power without the harmful emissions produced by burning coal. But are there other costs? Hear from a Chinese professor whose opposition to the dam has waned, but who calls for careful attention to the problems that this dam has created ...

Severe erosion in the Upper Murray River

Farmers along Victoria's Upper Murray claim that soil erosion on their properties is being caused by water released from the Snowy Mountains Scheme, a hydro-electricity project located in the Southern Alps. This clip from 2013 investigates the degradation occurring in an area where prime agricultural land is valued at 10,000 ...

Eroding more than sand in coastal towns

In English coastal villages, erosion by wind and waves has washed away great swathes of land. What drives this process? Can anything be done to protect people's homes against the merciless power of the elements?

Spectacular landforms shaped by erosion

Take a trip around the English coastline. In each location, the erosive power of the wind and the waves is obvious. But it's differences in the underlying geology that account for the diverse range of landforms that you are about to see.

Using lasers to fight coastal erosion?

Coastal settlements are often battered by forces of erosion. See how planners use accurate, reliable data about the changing coastline to combat erosion. Take a trip to the beach to see how technology, including GPS and airborne laser systems (Lidar), are lending a hand.

River flow vs particle size

Moving water can be a powerful force of nature. The speed of the water flow directly affects particle movement (transportation and deposition). See how the Hjulstrom Curve graph helps understand erosion by plotting the relationship between particle size and river velocity.

Fixing a scarred landscape

Is soil our most important natural resource? Erosive scars in many parts of Australia's agricultural landscape suggest we should be doing more to protect this asset. Meet Peter Andrews, a soil advocate. Peter's approach to landscape management might be unconventional, but it appears to be gaining support.
