World’s Dams Unprepared for Climate Change Conditions


Dams have been designed for river flows that will soon no longer apply, according to new research.

The conventional method of building dams is fundamentally flawed, said Matthews. Looking at the available data, engineers decide on a flow rate that they feel will optimize the infrastructure project. The problem, says Matthews, is that historical data is not a very good guide to the future of freshwater resources — particularly now that extreme water conditions have been exacerbated by a rapidly changing climate.

According to the United Nations, humans will feel the effects of climate change through the water supply. The hydrological cycle — which includes surface and ground sources, glaciers, precipitation, runoff and vaporization — is very sensitive to small climatic shifts. This is a concern not only because water is essential for subsistence, but because it’s also the key to economic development. The way humans are managing water infrastructure and conservation, the authors argue, is only intensifying these issues.
