Feasibility study for the use of recycled water in Larnaka

- ~ 55 m high earthfill dam
 - Foundation and abutment grouting is essential in order to minimise water losses

Software development for the operation of the National Data Bank of Hydrological & Meteorological Information (NDBHMI - 3rd Phase) using GIS - Publish of the Database

The project comprises of 5 discrete phases:
- Data entry and processing
- Software and equipment supply for web operation
- Automatic Telemetric Meteorogical Station Network
- Locate position using GPS
- Consulting and Project Management - Technical Suppport - Capacity Building

Triantafyllia dam and appurtenant structures design / Technical Consultant for Triantafylia dam works construction

It is a rockfill dam with clay core, 77m high and 560m crest length. The total volume of the dam is 2.700.000m3. The dam is founded on gneiss. Dam reservoir’s capacity is 12.000.000m3.
The spillway has discharge flow of 370m3/s (PMF), with maximum width 32m. The energy dissipation is achieved through a flip bucket and a steeling basin.
The cross-section of the diversion tunnel is of horseshoe shape with 150m radius. When the construction is over, it is converted to an intake and reservoir drain works.

i-adapt: Innovative approaches to halt desertification in Pinios. Piloting emerging technologies

The project seeks to provide a specific, actionable plan for combating desertification based on emerging technologies piloted in parts of the basin and quantify the expected impact of this plan on the water balance and local economy.
Specific project objectives include:
1.Engage stakeholders to identify major impacts of desertification in Pinios and existing applications of new technologies and techniques (agriculture).
2. Identify and assess the effectiveness of all existing initiatives, pilots and experimental applications of new technologies.

Hydraulic design and hydrology reports of Patra-Pyrgos-Tsakona (PAPYTSA) Olympia Odos Highway

The new Patra - Pyrgos - Tsakona (PAPYTSA) Motorway follows, in general terms, the same route as the existing road. It travels south from Pyrgos to Kalo Nero and then turns east through the valley bounded by Mt. Tetrazio to the north and the Kyparissia mountains to the south, until it intersects the Tripolis – Kalamata Motorway at Tsakona, where the Olympian Highway ends. The main studies of this project were:
- Hydrology - Discharge determination of watersheds at several Geographical Units of Patra Pyrgos highway

Environmental flood protection works in urban areas - Adjustment of Xerias stream in Korinthos

Xerias river basin has an area of 174 km2 and extends from the town of Korinthos (North) to the Southern districts of the Korinthos Prefecture, at the frontier with Argolida. Xerias river flow is seasonal with intense fluctuations. The January 1997 storms caused serious disasters.
The works included:
- Open and closed parts combination with composite concrete/steel sections, 1330m long.

Final study of the primary and secondary irrigation and drainage network of area II in Serres

This project is part of the reallocation plan for the plain. Therefore the existing irrigation system is fully redesigned, taking into account the optimal utilisation of the available water resources.
The works included:
- The designed network covers an area of 160.000.000 m2.
- It is consisted of 9 irrigation zones, which are irrigated by pumping stations. Kerkini lake is the main supply reservoir providing water to all the irrigation zones through the main delivery canal.
- Downstream Control is used.

Technical consultant for the Amira-Ag Vassilios dam

The project consists of the following individual works:
- The main embankment dam
- The spillway (collector, spillway canal, flip bucket, plunge pool)
- The diversion works which are combined with the intake and reservoir evacuation works.
Specifically:
- The dam is 48 m heigh with an impermeable core. The embankment cross section is trapezoid with a 2:1 (v:h) slope inclination and upstream-downstream berm provision.
- The diversion works are formed prior to the main fill construction. The 4mx4m rectangular culvert is 377 m long.

Schinas dam in Karpathos

The Schinas dam will be regulated along with the Vroutsas dam. The total project is part of the general water resources management project for the island of Karpathos, and also operates as a flood protection scheme.
The works include:
- The Schinas dam is of rockfill type with a clay impervious core .
- Height 31m. Crest length 242m. Crest width 8m.
- Embankment volume 420.000m3
- Total reservoir net volume 1.100.000m3.
- Maximum reservoir water surface 141.000m2.
