Introduction

The chapter provides an introduction to the fluvial hydrodynamics, scope, and outline of this book. As the subject deals with the interaction between fluid and sediment particles, an understanding of the physical properties of fluid and sediment is an essential prerequisite. In this chapter, the properties of fluid, sediment, and fluid–sediment mixture[aut]Fluid and suspended sediment mixturefluid–sediment mixture are discussed in details. The additional feature of this chapter is the discussion on terminal fall velocity of particles.
