Abstract

Working together with natural systems, which are powered by a diversity of life within them, provides a range of benefits to society, ranging from carbon storage, clean water and air to reduction of climate change impacts and protection against floods and other environmental hazards. This realisation has led to the concept of Green Infrastructure (GI): a network of natural and semi-natural features that intersperses and connects villages, towns and cities. Rivers are part of this green network, which has the potential to provide higher resilience and cost-effectiveness as well as more social and environmental benefits than conventional infrastructure. This document focuses on river engineering (which is concerned with river works) and therefore, we consider the river or watercourse as a natural or semi-natural corridor or infrastructure element. In this context, GI approaches are those that promote the conservation or restoration of the natural (green) character of our rivers. These approaches are fundamental to improving the water quality, morphology and ecosystems of rivers as well as contributing to an overall strategy to help people and communities adapt to the impacts of climate change.
