Upgrade of the hydraulics laboratory for the modeling of water supply networks & design and operation optimization study - ‘HYDROGIS LAB’
WP1- Project Management. The WP includes the activities of management, organization and coordination of the Project focusing on solving any problems or difficulties arising during the implementation phase of the Project. The main objective is to ensure compliance with the time schedule, to distribute financial resources and undertake the financial management of the Project.
Because of the nature and importance of the Project, the main objective of the WP is the immediate dissemination of the results to all the authorities such as Water Boards, Municipalities, Ministry of Agriculture and Natural Resources, Ministry of Communications and Works, Associations of Civil & Mechanical Engineers, etc. It is considered almost certain that the results will be of immediate interest and use, since they can form the basis for solving some of the most pressing water supply problems in our country.
The study of an existing selected water supply network and the collection of the necessary information by CUT (HOST) and the Water Development Department (PA1) for the network and its systems will be followed by an imaging of the pipes using a radar scanner and its design using special software and GIS. Satellite images, which will be transformed into the local reference system using special software, will be coupled with the digital imaging of the existing maps. The information will then be organised in such a way allowing the development of maps and their analysis at different levels (e.g. water supply network, buildings, water supply elements, geographic information, features of the network’s systems, etc.).
The main objective of the WP is to upgrade the existing infrastructure and develop an experimental setup (on scale representation) of an existing representative water supply network. The innovation of the technique, to be followed, lies in the possibility for accurate laboratory representation of the network’s systems (piping, joints, fittings, pumps, valves). The WP will be completed with the initial tests in order to develop the required know-how for the operation of the upgraded equipment and solve any problems in the model/experimental setup.
The objective of the WP is to develop specifications and relevant computational tools for the optimum analysis of supply networks, both in the design and the operation phase. An optimization framework will be defined, including the identification of the problem (determination of control variables and performance criteria) and its solution, using multicriteria evolution algorithms. This methodology will be utilized in the context of an information system for the management of networks, which will include a database, a GIS and a computational code. In order to implement the computational code, existing tools and models will be used or new ones will be developed, so as to ensure compatibility with the proposed methodological framework.
The operation of the experimental model will be studied in detail, with the support of specialized instruments and systems for the continuous recording of the variables (i.e. flow capacity, pressure, power etc) at different points in the network. The experimental results will be utilized for verifying the theoretical models of WP5, as well as for developing a framework for the identification and optimum adaptation of critical parameters of the simulation models (e.g. surface roughness coefficients), based on the measurements in the corresponding hydraulic model. Furthermore, specialized analyses will be conducted in typical locations of the experimental model, which may prove to be problematic (e.g. cross-sections downstream and upstream of the pumping stations) in order to study flow phenomena (e.g. local losses at operational phases) and propose improvements.
