Syllabus

CFU: 3

SSD: CEAR-01/B

Duration and Schedule: available here

Office hours: Tuesday 10-12 or by appointment

OBJECTIVES

Show the methodologies used to perform laboratory and field measurements of hydraulic variables like pressure, velocity, discharge, water level. Laboratory and field application of some of the methodologies learnt in the course.

DESCRIPTION

Introduction
Theory of measurements, dimensions, errors definition and their statistical analysis.

Pressure measurements
Manometry and use of pressure transducers in dynamic measurements.

Velocity measurements
Measures based on mechanical principles (Pitot tube, vane anemometer); measures based on optical principles (laser anemometer (LDV) and its application to turbulence measurements); outline of PIV measurements. Ultrasonic techniques.

Water level and velocity measurements in free surface flow
Velocity measurements based on mechanical principles (use of current meter and their calibration); ultrasonic measurements.

Measure of discharge in open channels
Hydraulic measurements (weirs, broad crested weirs); discharge determination through local velocity measurements; discharge measurements using ultrasonic techniques.

Discharge measurements in pipes
Recall of traditional techniques and their applications (e.g. Venturi Tube); ultrasonic flowmeters.

Outline of hydraulic physical models and of measurement of the hydrodynamic coefficients.

REQUIREMENTS

Basic knowledge of hydraulics

Bio: Gabriella Petaccia received the M.S. degree in Environmental Engineering in 2000 from the University of Rome “La Sapienza” and the Ph.D. degree in 2004 in Civil Engineering from the University of Pavia, Italy. Since 2007 she is Professor Assistant at the Civil and Architecture Department of the University of Pavia.

She has been author and co-author of 14 journal referred papers and 36+ papers in peer-reviewed conference proceedings/book chapters (160+) citations. She teaches the Flood propagation and the Hydraulic Measurements Course at the Ciivil and Environmental Engineering Course.

The main research interests lie in the hydraulic risk assessment, the development of models for the propagation of natural and artificial flood waves, wood debris transport.
