Fluvial Design Guide - Chapter 3 Background

Fluvial geomorphology

Suzie Maas and Andrew Brookes

This chapter provides an excellent introduction to the developing science of fluvial geomorphology and its application to the design of works in rivers and streams.

The chapter commences with a comprehensive answer to the question ‘What is fluvial geomorphology?’ and continues with a description of the main drivers of conservation and sustainability.

The role of geomorphology in fluvial design is explained, with the key issues usefully summarised in four key questions that a geomorphologist would typically ask

The various analytical and assessment ‘tools’ used by a geomorphologist are introduced and explained, and more details of each are provided in an annex to the chapter.

The chapter is completed with a series of illustrated case studies that describe the approach adopted by the geomorphologist to each particular project. These include catchment baseline survey, geomorphological scoping study, fluvial audit, geomorphology mapping, sediment modelling, monitoring of river restoration, and river reconnaissance.
