Language of instruction:

English

Assumed knowledge on:

Introductory Physics (BIP-10306); Water 1 (HWM-10303), Water 2 (AEW-23803), Water Quantity and Quality (SLM-20806), Field Practical Hydrology, Meteorology and Water Quality (HWM-23306)

Continuation courses:

Geophysical Fluid Mechanics (HWM-23806), Hydrology and Geology of Deltas (HWM-33306), River Flow and Morphology (HWM-30306)

Contents:

Note that students who followed the course Hydraulics and Hydrometry (HWM-21806) are not allowed to follow Environmental Hydraulics because of the large overlap between these two courses.
The course provides basic knowledge of hydraulics for application in quantitative water management (e.g. design of rivers, flood protection measures and hydraulic structures). By concentrating on a detailed explanation of the laws of conservation of mass, momentum and energy, the course aims at providing the student a clear understanding of steady water flow through conduits, rivers and canals.

Learning outcomes:

After successful completion of this course students are expected to be able to:
- dalculate hydrostatic and hydrodynamic pressures and resulting forces on structures;
- calculate water level and flow velocity in uniform open channels;
- calculate surface level profiles for gradually varying non-uniform flow (backwater curve, draw down curve), with the aim to know the consequences of measures in currents and streams;
- calculate energy losses in closed pipe systems using friction coefficients and loss coefficients;
- measure hydraulic variables in the laboratory and apply theory to the observations;
- design a water course (planform, cross-section and structures) for a case from current water management practice, analyse data from a numerical model and evaluate uncertainties and assumptions;
- execute a project, including setting up a work plan, time planning, presentation and report writing.

Activities:

The course consists of 3 parts:
1. Hydraulic theory (4 weeks): In the course reader, proofs, derivations, theory and worked examples are given in full, but using simple mathematical notation and an ample amount of clarifying text. The following topics are covered: hydrostatics, measurement of pressure, flow and discharge, flow through pipelines, uniform and non-uniform open channel flow and steady flow around hydraulic structures.
2. Laboratory experiments (1 week): Students perform experiments in the Kraijenhoff-van de Leur Laboratory for Water and Sediment Transport using different types of flumes, conduits and measurement equipment to understand the hydraulic theory.
3. Design assignment (3 weeks): Students apply the newly acquired knowledge in a case inspired by current water management practice. For example, students could make a plan to restore a canalised brook and design and compute a planform and cross-section leading to appropriate water levels, accounting for discharge variability, aquatic vegetation and hydraulic structures. Computations will be made with a hydraulic model and the output will be analysed in R. Students also learn to plan and execute a project with time restrictions, discuss assumptions and uncertainties in their approach, present their findings, and write a short report.

Examination:

Written examination (50%) and written report of design project (50%).

Literature:

Lecture notes available from WUR-shop and scientific papers.
