Sand dams - A water solution for drylands areas

10 December 2020 18:00-20:00, London, United Kingdom


Introduction
A sand dam is a reinforced stone masonry wall built across a seasonal sandy river. It has almost no maintenance costs and can last for upwards of 60 years (the oldest known in operation being over 100 years old). Water behind a sand dam raises the water table in the surrounding area, which improves the soil, creating better conditions for crops and grazing. David Jodan will describe the water-saving potential of the established technology for many areas of the world.
