The major external, or allogenic, controls on fluvial sedimentation are tectonics and climate. This chapter considers tectonic controls; climatic controls are discussed in Chap. 12. Base-level changes, driven either by tectonism or eustasy, are of great importance in controlling fluvial style and sedimentation rates in the lower reaches of rivers, through the control base level exerts on regional slope and sedimentary accommodation space. The role of eustasy in controlling stratigraphic processes remains controversial and is described in Chap. 13, where the main theoretical discussion of sequence stratigraphy is presented. In this chapter changes in base level are considered as relative changes, and their effects on stratigraphic processes in the fluvial environment are considered without entering into the tectonismversus-eustasy debate.
