Development of a modular system for application in iwrm practices and flood prevention, organisation of egms database

The output of the project will consist of a system for assessing the risk of malfunction of water construction works on the basis of gms monitoring by means of the egms software tool and database as part of geophysical inspections of embankments.

The purpose of the eGMS project is to continue in contemporary research (projects IMPACT (FP5), Floodsite (FP6) and EUREKA project E!3658 GEMSTONE) and complete the GMS (geophysical monitoring system) with an innovative module system that will serve for the processing and interpretation of data acquired during the application of the GMS, but, above all of its first basic part - Quick Testing Measurement (QTM). The project eGMS will help the final users (managers of embankments & dikes, Technical Security Departments, region and town administrators) to acquire information of high quality relating to the risk resulting from non-homogeneity and instability of flood embankments. The analysis of flood protection dike defect formation by GMS and eGMS software will show that with most defects “hidden” causes of their occurrence can be discovered which developed gradually or existed even before or in the course of the dike construction. It can be natural conditions (for example founding the dike in the place of a hidden old river channel filled with permeable sediments), construction faults or unsuitable materials used in the course of building the dike. Also, repeated water attacks during regular floods can bear a serious influence, when subsoil or dike body material is flushed out and away or when the hillsides of the dike are continuously deformed and eroded (pre-breach formed defects). In case of final users from the field of insurance companies, the developed software will allow for considering the real risk of flood danger under given conditions and its development in time. The module system should be developed for application in all EU states (i.e. for linear embankments of all European river basins where the GMS can be applied), on the pilot sites in the CZECH REPUBLIC and SLOVENIA, and also tested on the coastal embankments on the pilot site in IRELAND, as the first application of such a tool in coastal areas. For effective mastering of abnormal conditions and to minimise the risk of bursting the embankments, the ability to identify the danger and vulnerability of these embankments in a reliable way is highly essential. Good knowledge of the possible behaviour of the construction structure is important also for their correct operation and maintenance. In many questions relating to potential damage of water construction works, our existing knowledge and ability to foresee correct behaviour of the constructions under dangerous situations are relatively limited, which makes both the inspection and reduction of risks difficult. Nevertheless, the group of experts joined together in the eGMS project, developed, in the course of 6 years’ research work within the frame of the IMPACT, FLOODsite and GEMSTONE projects, an effective monitoring system applicable to all flooding embankments in Central Europe and maybe even in the frame of all Europe and selected catchments in the U.S.A. This Geophysical Monitoring System (GMS) is able to give sufficient information for the assessment of risks, in other words for the localisation of weak spots in line embankments, which could be subjected to defects and dike ruptures under extreme hydrological conditions (floods). In the practical application of the eGMS project, the GMS will be complemented with the technical safety visual inspection and interpretation of air/satellite pictures as usual within the frame of catchment inspections. The whole process will be unified by means of the eGMS software tool and database with simultaneous consideration of an international dimension. The geophysical monitoring system (GMS) has been designed as a kit consisting of 3 basic building stones. The basis of the GMS consists of a database of repeated geophysical measurements, which will be performed within the frame of monitoring the system of water construction works. The monitoring function consists in the analysis of relative changes of measured geophysical parameters. The designed eGMS module system will offer for a series of users the possibility to utilise a complex information support of the GMS adapted generally to the field of water economics and will allow for solving the problems of preventing floods and predicting weakened areas in linear water construction bodies, including the results of modelling, simulation and complex analyses, which will significantly improve the quality of deciding (comparison of scenarios, variants of solutions, suggestions of infrastructure changes and repairs of embankments, etc.) As at today, no other rival prototype exists in Europe. The GMS with potential application of the module system is therefore unique, nevertheless, it is necessary to start the development of the eGMS as soon as possible (in 2009 at the latest) because the competition in this branch is increasing significantly.
