Steady non-uniform and unsteady continuously changing flow in open channels and pipes, filling and emptying of non-prismatic reservoirs and lock chambers. Shaft and lateral spillways, chutes, types of hydraulic jump and design of stilling pools.
Basics of model similitude in fluid mechanics. Selected chapters of object hydraulics and pressure systems hydraulics.
Practical aspects of groundwater flow, principals of continuity and deterministic. Assumptions accepted for ground water flow solution, simple water intakes, simple models of flow through a dam, solution of system of wells.
The findings are applied in computational and laboratory exercises.
