Water Resource Management

Water Resources Management (WRM) is the process of planning, developing, and managing water resource, in terms of both water quantity and quality, across all water uses. It is an aspect of water cycle management. It includes the institutions, infrastructure, incentives, and information systems that support and guide water management. Effective, sustainable management can promote development.

Integrated water resources management encompasses social, economic, and environmental development. Our expertise focuses on modeling and systems development, including hydrologic, hydraulic, water quality, and reservoir modeling; the economic analysis of water management decisions; the evaluation of climate change impacts; and the valuation of ecosystem services.

The aim of the project is the development of naturally established methodologies for modeling and forecasting strong storms and associated flooding phenomena. The approach concerns the adaptation of rain-runoff models to the peculiarities of the Greek hydroclimatic and geomorphological conditions, and on the one hand to the requirements of the recent European Framework Directive 2007/60/EC.

The project structure follows a holistic approach. In particular, starting from the collection of the necessary hydroclimatic, hydrometric and environmental-geographical data (an action on which the specific priority area gives special emphasis), a naturally established mathematical representation of the processes is attempted which is pilot tested. Achieving the various research and technological aspects of the project requires the collection, processing and analysis of a sufficient amount and good reliability of flood hydrology data.


This project is characterized as a Special and of a national importance.

It is a study which constitutes one of the two main regional anti-flooding projects of the greater Thessaloniki area (the second is the Peripheral Ditch) draining the entire drainage basin from the west, but also from the northeast. In the Dendropotamos catchment area, significant and extensive flooding has occurred and continues to occur for many years, also a result of the failure of the city’s existing drainage system during periods of extreme flooding.

The aim of the project is the study of the required anti-flood protection projects E.P. Thessaloniki with settlement projects in the hydrological basins of the river Dendropotamos and its associated streams, streams in the Municipalities of: Oreokastro (north), Delta, Kordelio-Evosmou, Pavlou Mela, Ampelokipon-Menemeni and Thessaloniki. The above study, which concerns the required flood protection and settlement projects of the river and the associated streams, includes: the hydrological study, the study of stream settlement and demarcation projects, the control of stream drainage, the study of pumping station projects, the hydraulic study of a microtunnel, the drainage checks, the study of road crossing techniques and the confluence of streams, the studies of storm drains and finally the updating of existing studies. The settlement alternatives provided are acceptable from a technical, urban, economic, social and environmental point of view and in accordance with the Flood Risk Management Plan.

It constitutes the Strategic Plan of Flood Protection Projects for the whole of the Water Division of Attica.

It is related to the implementation of Measures resulting from the implementation of the European Directive 2007/60, as it was implemented in Greece.


  • Collection
  • Indexing
  • Digitization
  • Evaluation and development of flood risk identification methodology
  • Prioritization of actions-activities
  • Geoportal development
  • Consultation

The presentation and management of the geospatial data created within the framework of the Master Plan, is carried out through the Geoportal created, which presents cartographically all the information collected and digitized within the framework of this contract.

A single database was created, with direct entry and management of data provided in a similar way (open standards based on INSPIRE and OGC directives).

The implementation of the Master Plan will be done by the Ministry of Infrastructure and Transport (M.I.T.) or the Regions, and after its finalization, it should be taken into account by all agencies whose projects are involved in flood protection, so that their projects are harmonized with the implemented general anti-flood planning of each region.

It consists of a study which included the Topographic Study to simulate the morphology of the Nestos River Valley and Delta, the Nestos Riverbed Delimitation Study for various values of flood discharges, as well as the maximum possible flood. The scope of the Delimitation Study concerns the control of the drainage capacity of the Nestos river bed, downstream of the Platanovrisi Dam and the estimation of the flood level and the extent of the Nestos river bed inundation in the cases of operation, both of the Generating Station Units and the Overflows, for various benefit values referred to flood return periods of 1:20, 1:100, 1:1,000, 1:10,000, as well as the maximum possible flood.

The aim of the project is: i) to determine, downstream of the Platanovrisi Dam and up to the mouth (Delta of the river), the inundation limits of the Nestos River bed, in the cases of operation of both the Generating Station Units and the Spillways, for various benefit prices referring to flood return periods of 1:20, 1:100, 1:1,000, 1:10,000, as well as the maximum possible flood (Scoping Study), ii) to update the Study of the effects of flood wave passage, from failure of existing Dams of the Nestos River (YS Thesauros and YS Platanovrisi) and new ones (YS Temenouis), downstream of the Dams, in the man-made and natural ecosystems of the area (Flood Wave Channeling Study). In particular, the Topographic works of the Nestos River were carried out in a length of 85 km, the Control of drainage and demarcation of the bed of the Nestos River, the Fracture Study using a three-dimensional flow analysis model and the Study of the channeling of the flood wave using a two-dimensional flow analysis model.
