REHABILITACIÓN DE PRESAS
WHAT IS THE REHABILITATION AND MODERNIZATION OF MONITORING SYSTEMS IN DAMS?
Dams are critical infrastructures designed to manage water resources and produce electricity, many of which have reached the end of their useful life or may require extensive rehabilitation.
In 2021, UNU-INWEH (United Nations University – Institute for Water, Environment and Health) published a report titled «Ageing water infrastructure: An emerging global risk.» The authors urged that by 2050, most of the earth’s population will live downstream of tens of thousands of large dams built during the 20th century, many of which have remained in operation beyond their useful life.
GROUP EXPERTISE
La rehabilitación de presas tiene por objeto garantizar la seguridad y el rendimiento operativo, y los sistemas de vigilancia geotécnica y estructural son esenciales para controlar, mantener y salvaguardar la integridad estructural. Furthermore, the design, verification, installation, implementation, and maintenance of monitoring systems typically require extensive collaboration among professional engineers from various disciplines.
Realizing maximum benefits and the return on investment in monitoring instrumentation systems strongly depends on the efficiency of the data management platform. This platform transforms data into valuable analytics based on which authorities can make timely and informed decisions.
SISGEO group is honored to collaborate with hundreds of professionals in various disciplines. Over the past three decades, it has delivered state-of-the-art instrumentation solutions to over a Thousand dams worldwide. SISGEO instrumentation solutions ensure high quality and provide dependable precision, usability, and, most importantly, unparalleled technical support.
SISGEO Group: SISGEO, SISGEO LATINOAMERICA, FIELD and HUGGENBERGERS, offers full spectrum of specialized instrumentation solutions worldwide including:
→ Diagnosis and functional tests on existing instrumentation
The inspection of instrumentation functionality and monitoring processes such as data collection, data storage, and telecommunication systems is essential for dam rehabilitation projects, implying the following actions:
- Retrieving the existing technical documentation;
- Identification of out-of-use instruments;
- Organizing historical readings and highlighting anomalies;
- Gathering new readings utilizing modern data loggers with data analysis capabilities;
- Evaluating the integrity of signal cables, electrical connections, and mechanical fixtures;
- Evaluating conversion formulas and regression models;
- Providing status reports and summarizing the findings;
→ Data acquisition, digitization, and online accessibility
Given the site specificity and the client’s needs, the existing infrastructure can often be upgraded to a fully automated platform. The automation of monitoring systems is necessary for a variety of reasons:
- To avoid or mitigate human error in the data collection process;
- To set and reset the sampling frequency and enhance statistical inference as necessary;
- To digitize and compress the data, which significantly enhances data transmission and the storage capacity for historical records and, more importantly, facilitates access to the records;
- To minimize the sunk costs due to the reduced cabling and complexity of the central data acquisition system;
- To allow real-time dynamic and static asset monitoring without human intervention.
→ Automatic surveying systems
Modern geodetic sensors, such as robotic total stations, have significantly enhanced the topographic monitoring of dams. Robotic total stations particularly incorporate high-precision rangefinders and allow direct measurement of the 3D coordinates of reflectors. They ensure precise measurements and automate data collection for increased efficiency. Remote operation enhances safety, while CAD integration streamlines design processes. Faster data processing reduces project timelines and labour costs, making them essential for modern rehabilitation projects. SISGEO’s data management platform (AIDA IoT) can fully integrate robotic total stations into any existing instrumentation infrastructure.
→ Design, supply and installation
Designing and implementing instrumentation and monitoring systems in engineering projects is vital for managing physical, engineering, and geological phenomena. Careful consideration of measurement needs, parameters, and instrumentation architecture is necessary. Critical parameters such as measurement range, frequency, accuracy, and data usage must be assessed. Design involves technical documents, plans, and maintenance schedules. Protecting instrumentation during civil works is crucial.
SISGEO, a leading inclinometer technology provider, emphasizes detailed specifications and user manuals for efficient storage and installation. The installation phase requires strict adherence to specifications.
SISGEO trains its staff for efficient installation, recognizing its impact on system performance. Meticulous design, detailed specifications, and expert installation are essential for high-quality monitoring solutions in engineering applications.
→ Data Management Software
AIDA-IoT, the SISGEO data management platform is designed to facilitate data visualization, analysis, and information processing, crucial for generating alerts and reports. For effective monitoring, a reliable cloud-based platform like AIDA IoT – powered by Field – is utilized. This platform efficiently stores and manages large volumes of raw data, generating alarms and reports as needed. AIDA IoT offers high customization, allowing for tailored charts and handling data from various monitoring systems, whether manual, semi-automated, or fully automated. Data acquisition units (DAUs) collect electrical signals from instruments, which are then transmitted to a central server for validation, processing, and integration into a SQL database. Clients benefit from real-time access to diverse analysis types, including dynamic, static, hydraulic, geodetic, and metrological information, through a personalized dashboard.
