HDR Confirmation: Laureano Gonzalez Rodrigez

We would like to invite you to attend the Confirmation of Laureano Gonzalez Rodrigez, a Master of Climate Change Adaptation candidate in the School of Science, Technology and Engineering.

Thesis Title: An innovative and low-cost technique for continuous monitoring of sedimentation impact on reservoir storage capacity.

Abstract: The literature provides evidence on the sedimentation rate changes in water reservoirs in contemporary times. In this research the main reasons causing this, and current methods used to determine sediment deposition are explored.

A new technology to obtain continuous sediment build-up from temperature measurements is proposed. The technology uses fibre optic cables and a Distributed Temperature Sensor (DTS) instrument that is capable of detecting temperature changes with a spatial resolution of up to one meter along its length. The hypothesis that associates these two parameters (sedimentation and temperature) is the different behaviour of the diurnal thermal waves in water compared to solids (sediments) due to the different thermal properties of each element. Expected benefits include accurate and opportune quantification of reservoir storage capacity, cost reduction associated with traditional measurement surveys and maintenance operations, as well as more certain predictions of water supply.

The research schedule and budget, as well as the publications expected from the main findings are presented. The investigation is designed in two phases where initial experiments are performed in outdoor facilities at USC. Then, the outcomes of the preliminary tests will be used to optimise the experimental setting and data gathering in a real reservoir. Finally, sediment depth measurements will be converted into topographic maps of the reservoir bed as an input for the determination of storage capacity. This Confirmation of Candidature considers the program upgrade from Master by Research to PhD Degree.


We look forward to seeing you there!
