The objective of the course is to provide a fundamental understanding of the phenomena and processes that govern the water flow in the environment with the special purpose of providing the students with knowledge to analyze the conditions for and consequences of human activities. Activities refer primarily to discharge of pollutants to different water bodies, but the interaction between structures and water flow is also discussed. A brief overview of basic sediment transport is included as well.

An overview of water flow in the environment – phenomena and processes related to such flow. Transport processes and spreading of pollutant. Balance equations for water and pollutants in surface water systems with instantaneous mixing. Piston flow and nominal retention time. Basic mechanisms for mixing such as diffusion (laminar and turbulent), dispersion, and advection. The general transport (advection-diffusion) equation – formulation and special cases. Mixing in rivers, lakes, and coastal areas. Jets and plumes (free shear flows). Near- and far field mixing. Diffusers and other technical solutions for pollution discharge. Field measurement techniques. Case studies concerning pollution discharge and environmental impact. Density-driven flows including stratification and horizontal spreading of pollutants. Temperature and oxygen conditions in natural waters together with governing equations. Interaction between structures and water flow. Basic sediment transport and boundary layer theory. Bed load and suspended load. Some commonly used sediment transport formulas.
