DESCRIPTION OF PRODUCT, SERVICE OR TECHNOLOGY

This project aims to prevent the occurrence of natural catastrophes that could occur if deformation and movements are not properly controlled in artificial and natural dams. Kinematic and dynamic modeling of hydro dams is based on the integration of information obtained from measurements of the variation in time and space of coordinates of a fixed reference point type (permanent GPS stations) as a reference framework for determining the detailed movements of components of the dam or of the whole system.

Determination of dam stability is essential to avoid disasters that can bring material damage and immeasurable human hardship. Therefore, keeping hydroelectric dam stability under constant surveillance in time and space brings immediate benefits in terms of reducing the risk of natural and artificial disasters and consequently protecting private and industrial investments in areas where there is this potential risk.

INNOVATIVE ELEMENTS OF THE PROJECT

Annual GPS measurements allow the determination of displacement vectors for constituent blocks of hydroelectric dams. Measurements in permanent stations ensure the attainment of a very precise geodynamic reference system.

 

The novelty of this project is complete automation of the system, both in the continuous acquisition of dam phase, the automated processing of raw data, and in the decision to alert the decision factors in case the network deforms.

THE COMPETITIVENESS OF PROJECT RESULTS

Creation of an embedded system of acquisition parameters to describe the state of dams (hydro construction) with facilities for rapid transmission of information without altering its content. Development and implementation of modern mathematical methods of multisensory information fusion.
Development of dynamic modeling methods - input output models - prediction of the behavior of dams and sizes of interest based on these models. Creation of an automated expertise system that minimizes human subjectivity in the interpretation of multisensory information and the prediction of the behavior of hydraulic structures. Creation of a decision support system based on permanent monitoring of dams and their behavioral patterns - related to external factors: weather and geophysical attributes which offer the human expert the possibility to predict behavioral hydraulic structures and facilities and their interaction with the environment.


ECONOMIC EFFECTS OF THE PROJECT


Effects from the manufacturer: It is evident that the system is absolutely necessary for environmental protection, avoiding severe environmental disasters, both social and economical. It will need to be adhered to by the overseeing organization such that dams are equipped with the most secure monitoring systems and that the system utilized is the most modern, safe and effective new system of real time warning of possible displacements and strains that may pose a risk for dam operation. Through the analysis of demand in relation to pricing, we can evaluate the amortization of the investments (funding from both the state budget and private sources) in approximately four years.


Effects on user:
• (1) Integration of regional and independent technological undertakings under the European Union requirements and regulations; 
• (2) Harmonization of policies for sustainable development; 
• (3) Reduction in the vulnerability of regions adjacent to dam waters and mitigation of the consequences of natural disasters and industrial accidents; 
• (4) Development, through the consortium formed for the project, a solid research base, support for the development of future projects in European research programs;
• (5) Continuous view of the dynamic evolution of the dam (real time) using GIS technology.


CONCLUSIONS ON THE CONTRIBUTION OF THE PROJECT TO INCREASE BUSINESS COMPETITIVENESS

We presented dynamic modeling requirements for dam behavior and defined requirements for ensuring the prediction of a number of sizes of interest. The models presented could be used for predicting future behavior of the structure under investigation. To this effect, a comparative analysis is conducted  of the main methods of prediction presented in literature, the time needed to perform the prediction, the presence of patterns in data, data requirements, degree of understanding of the method and implementation cost that it implies.

 

After the first analysis by the team, a conclusion regarding dynamic system modeling was reached: this approach offers the best framework for supervision and effective monitoring, and it follows that prediction will use these models.

 

MANAGEMENT AGENCY OF SCIENTIFIC RESEARCH, INNOVATION AND TECHNOLOGY TRANSFER

CONCLUSIONS

Based on instrumental investigations, the structural evolution of behavior could be assessed and the subsequent response in the linear elastic domain. During the research program, instrumental investigations were carried out in several stages, following the "hot season" and "cold season" and the water level in lakes and reservoirs.

Given the modal parameters and vibration intensity highlighted by comparing the results of instrumental
investigations and preparing their results after calculations, structural conclusions could be drawn about the
current technical condition of dams and pilot behavior and their ability to respond to dynamic actions, including
seismic conditions of maintenance and prediction of their behavior with dynamic future applications.

Several steps were carried out to this effect: 

The entire research program led to a better control of current structural safety of dams and initiating measures to reduce the risk posed by
these engineering structures and not ultimately increase the general level of knowledge in this field.
