River Works - Flood Protection & Erosion Control

Flooding is a predominant natural hazard here in New Zealand, and throughout the world.  It is an issue that affects both rural and urban environments.  With the added pressures of climate change compounding the situation, the issues associated with rural and urban flooding are only going to become more and more prevalent.

Erosion, loss of land, and the resulting deposition of sediment is another challenge when it comes to cohabitating the natural environment with rivers and streams.  The staff at e2 have the on-the-ground experience to offer the insightful, honest, and the right advice when it comes river management decisions.
