| 1st Phase of computerisation |
 |
| 1.1 Creation of a Data Base Bank (Data Base). |
|
| The creation of a data base bank is composed, inter alia, of: |
|
| -
- | Geographical data (measurement stations, catchment areas, projects, networks)
Hydrometeorological (surface water, ground water, rainfall) and management data. |
| | |
| The Geographical Data Bank can supply all central and regional applications using geographical data. The proper creation and management of the Bank may support the Services of the WDD at a great extent and significantly reduce the time required to recover and suitably prepare geographical data. |
| | |
| The procedure to build/ create the GIS data bank included the following: |
| -
-
-
-
-
-
-
-
-
-
-
-
-
- | Design of data base
Designation of boundaries in the field study
Designation of a system of coordinates
Planning the levels of information required
Designation of the descriptive information to accompany the level features
Codification and organisation of descriptive features
Introduction/ transfer of data
Introduction of the geographical data in the data base, digitalisation or digital conversion from other systems
Creation of geographical relations
Connection of geographical-descriptive information
Data management
Conversion in the designated coordinates systems
Creation of indexes
Necessary processing of the elements of the data base records |
| | |
| 1.2 Management systems |
| | |
| The management systems installed at the WDD are EDAMS software units developed by Hydro-Comp Enterprises Ltd. The multi-level and staged design of the systems enables their implementation as an operational system to a wide network of distributed systems in Oracle or SQL Server. The systems were installed using specific installation methodology for each product and handle issues such as the reconstruction of operational processes, change management, transfer of data and specialised training. |
| | |
| 1.2.1 Subsystem for the Management and Processing of Geographical and Hydrological Data |
| | |
| The Subsystem for the Management and Processing of Geographical and Hydrological Data is EDAMS Hydrology /Water Resources Management (Surface Hydrology). The system is based on the infrastructure of all EDAMS systems and uses hydrological models from US Army Corps of Engineers (HEC) with the following features: |
| -
-
-
-
- | Data bases for the formation of an integrated management of surface water
Management of geographical information and ability to carry out advanced geographical processing
Simple rainfall-run off model (aggregate)
Interconnection between the rainfall- run off model with the central geographical information data base so that various hydrographic and geographical data necessary for the construction of the model are automatically entered from the base to the model
As well as interconnection of the model with CYMOS data base for the entry of meteorological and hydrological data time series which shall be used in the model for simulation and calibration purposes. |
| | |
| 1.2.2 Network Management Applications |
| | |
| For the purpose of the management of Water supply, Irrigation recycled water and sewage networks, the EDAMS Network Asset Management system has been installed at the WDD, and it is structured in such manner as to successfully and easily store and organise data about water supply/ irrigation/ sewage networks.
The system includes the whole spectrum of network management per category such as: |
| -
-
-
-
- | The recording of network data
The analysis and assessment of network data
The management of network data
The mapping ability
The management of network zones |
| | |
| The system supports the uninterrupted interaction with the Geographical Information System and allows unlimited access to territorial data for all operational and management functions. |
| | |
| 1.2.3 Hydraulic network solution applications |
| | |
| The hydraulic network solutions will allow the WDD engineers to perform Network Analysis of existing networks and design extensions or new infrastructure networks. The GSI together with the relevant EDAMS applications, Network analysis, Water supply/ Irrigation Recycled Water (EDAMS Network Analysis-Water), the Hydraulic Network Solutions is achieved on the basis of mathematical model (EPANET engine) as well as the dynamic simulation of the network, the optimisation of cost and the analysis of water quality.
Furthermore, the EDAMS Network Analysis-Sewer)- hydraulic solution of Sewage Networks. The system identifies problems such as pipes with a shorter diameter than the prescribed one or very high speed pipes. |
| | |
| 2nd PHASE OF COMPUTERISATION |
| | |
| The main objective of this phase is the further development and extension of applications to more Services and users so as to fulfil the task requirements and support the strategic objectives of the WDD. In addition, by exploiting the infrastructure created in Phase I, the WDD may proceed to more specialised applications, which shall give greater value to existing data and increase the analytical and functional capacity of the systems. |
| | |
| 2.1 Indicatively, the separate applications of Phase II are the following: |
| | |
| -
-
-
-
-
- | Further extension of the systems of the 1st phase to the Services and district Offices
Fixed assets and networks operation and maintenance system
Measurements, remote interconnection and water quantity balance
Applications of levelled access to various subsystems from the internet
Water system and dam safety management systems
The above applications will not be independent, but they will form the separate subsystems composing the complete GSI. |
