Aim
This course will give the students a basic knowledge of water related problems. The students will be able to use their knowledge to solve various engineering problems related to water resources management, urban hydrology and the design of hydraulic structures.

Knowledge and understanding
For a passing grade the student must

• explain and use fundamental hydrological processes and their interaction within the hydrological cycle

• describe fundamental hydraulic concepts like continuity, energy equation, and the momentum equation.

Skills and abilities
For a passing grade the student must

• solve an urban hydrology problem in an efficient and structured way

• be able to calculate groundwater flow using Darcys law.

• calculate dimensions of pipes, pumps, and turbines

• calculate the magnitude of forces using the momentum equations

Judgement and approach
For a passing grade the student must

• present a solution to a water related problem in a technical report.

Contents

• descriptive and quantitative hydrology: The hydrological cycle, hydrological processes, precipitation, evapotranspiration, infiltration, soil moisture, groundwater, runoff, and hydrograph analysis.

• fluid mechanics: Fluid properties, fluid statics, continuity equation, momentum equation and energy equation.

• applications: Pipe flow, sanitary engineering, urban hydrology.
