Advanced laboratory techniques in hydraulics

Recommended Prerequisites

Training required in Hydraulics, Informatics, Numerical Methods and Statistical Methods.

Teaching Methods

Lectures on theoretical aspects of some techniques and practical application comprising presentation of data, processing, analysis and discussion of data. The course evaluation consists of an autonomous work with tutorial supervision comprising measurement, data management, programming, presentation.

Learning Outcomes

The objectives of this course are to provide students knowledge on laboratory techniques for the measurement of hydraulic features, including traditional and advanced techniques, such as free surface position, instantaneous velocity, turbulence, air concentration, sediments and water quality and also promote the acquisition of knowledge of specialized methodologies in the treatment and analysis of different data provided from the different techniques.

It is intended that students develop skills of independent learning, organization, programming, analysis and critical thinking, focusing, synthesis and presentation, enabling practical application on specific flows studies.

Syllabus

1. Concepts and techniques of measurement hydraulic features such as free surface position (resistive probes and pressure transducers), average, instantaneous velocity and turbulence (Pitot, Prandtl-Pitot, anemometry, acoustic and based on digital images), air concentration (dual-tip conductivity probe), sediments and water quality (multi-parametric, Spectrometer probes). Techniques analysis and comparisons.

2. Calibration process, data base, data storage. Data analysis, errors and uncertainties.

3. Digital Image Analysis and Processing. Operations and software using Matlab.
