RFP
Until today, there have been serious problems created by flooding. The prioritization of solutions was based primarily on the size of the problems that appear. Z&A through this study, developed flood management models which will provide a convenient tool for prioritization in particular as regards access to funding from E.U. resources. The project included the following: (a) selection of important streams to be included in the management plan, (b) appropriate mapping of relevant catchments, (c) description of the necessary studies for each stream (flood plain, hydraulic studies, etc). Registration of flood protection works or/and settlement in obstructing of streams and (d) proposals on necessary land use changes to achieve the flood protection goals. The projects that were supervised by Z&A were the following:1. “Stabilization of natural slopes and arrangement of river bed of Pamisos stream in Mouzaki Municipality, Karditsa Perfecture”, 2. “Arrangement works on Saint George stream of Dramiziotis river in Trikala Prefecture” 3. “Recreation and environmental protection of Dipotamia river in Kastoria Prefecture” 4. “Arrangement works on Baggo stream of Anthiriotis river in Karditsa Prefecture” 5. “Flood protection works on river Asopos in East Attica Prefecture”.

DETAILED DESIGN OF WORKS NECESSARY FOR THE ENVIRONMENTAL PROTECTION OF KOTYCHI LAGOON, ELIA PREFECTURE, PELOPONESSE, SOUTH GREECE
Country: GREECE , Year: 2006 - 2006 , Client: - , Funding: - , Contract Value: - , Tags: Water Resources Management
RFP
Soil loss using RUSLE from the Kotychi basin was estimated using GIS software resulting in a spatial representation which enabled targeting of particular streams and areas of high contribution to the lagoon's sedimentation problem. The targeting of areas informed the design of specific hydraulic works to allow the diversion of freshwater into the lagoon during low flows while at the same time diverting away sediment-laden floodwaters during the rainy season. This arrangement helps in the management of the lagoon's salinity levels and at the same time provides relief from excessive sedimentation.

RFP
The global objective of the project is to demonstrate and disseminate a European knowledge management framework, for a procedure (HYDROPLAN) on sustainable asset management with integrated links to best available technologies.
The target is to provide a comprehensive framework tool to share knowledge and collaborate in the development of best management practices and technologies. These practices will then be taken into consideration for pragmatic, cost effective and objective master planning decisions in the European sewerage sector.In Greece the life cases were in Athens (EYDAP) and Thessalonica (EYATH) where the HYDROPLAN methodology was implemented. The objective is to develop an advanced management tool, which will be used in order to take cost effective and pragmatic decisions for the network of the pilot area. With the use of the management tool the Sewer Authorities are planning to improve the functionality of the network and program future investments with the best cost effective way.
