Road Crossings for Water Harvesting in Dry Rivers: Non-Vented Drifts as Sand Dams

This Practical Note discusses the siting, the design and the construction of road crossings in dry
riverbeds to harvest and retain flood water. With extensive road construction programs ongoing in
most part of the world and 60% of new roads to be added from 2010 to 2025 globally, the
opportunities to combine road development with water management are substantial. Within this the
use of road drifts – in particular the use of nonvented drifts functioning as sand dams in semiarid
and arid areas – is an important and in most countries underutilized opportunity to harvest flood
water. Read the note here.
