Supporting river basin and coastal management in central greece

To manage and restore the Spercheios river basin and its coastal zone, the Hellenic Centre for Marine Research (HCMR) needed a holistic view of Spercheios’ river basin and coastal zone.

Their obstacle was lack of access to timely and accurate data that is centrally stored and readily available. Database engineer salary There was also a need to integrate these data to models and DSS.

Local authorities had to be better prepared for the threats of frequent flooding and poor water quality, to ultimately reduce financial losses and health risks for the local community. Jstor database Solution

Implementing our monitoring, forecasting and water quality management system meant that the client could now obtain, manage and use data more efficiently than ever before.

• An online system capable of producing accurate model forecasts, water balance reports and early warnings regarding river flooding and basin hydrology

Spercheios River and its deltaic system is located in Central Greece, close to the historic site of Thermopylae. E m database Many ecologically-important areas protected under the NATURA 2000 network are located within the 1828 km2 Spercheios river basin. Data recovery richmond va Anthropogenic interventions in the deltaic area, especially after the 1950s has influenced its natural habitats. Data recovery software The main interventions include:

• Constantly increasing intensification of agricultural cultivations that have been expanding on the natural riparian vegetation at the expense of habitats biodiversity

• Wastewater and solid industrial wastes that aggravate the natural habitats and affect the fauna and water quality of surface and underground waters

• Construction of roads, irrigation and drainage networks that have significantly altered the natural drainage regime, thereby aggravating the flooding problem. Data recovery advisor The area is also frequently affected by heavy rainfall and floods that take place about once every three years.

The project’s ultimate goal was to combine all individual, optimised environmental tools, models and indicators (biological, hydrological, water quality, socio-economic, and so on) in order to obtain a holistic view of the study area’s aquatic environment. Database host name Solution

The implemented DSS served as a development platform for data collection, processing, integration, quality assurance and monitoring. Database performance It is also used for updating of models, forecasting and web publishing/sharing.

It receives distributed rainfall and temperature data from the ‘Poseidon’ meteorological system as a primary model input as well as monitors data from stations installed in the wider basin/coastal areas to perform the following tasks in an automated, scheduled and self-supervised way:

• Provides 2D distributed daily hindcasts for the last ten days and daily four days forecasts for hydrological parameters such as actual evapotranspiration, aquifer recharge and soil water content

HCMR also simulated the 3D hydrodynamics of Maliakos Gulf circulation and its water quality by combining outputs from the hydrological model with the Gulf’s boundary conditions. Data recovery broken hard drive Results

The timely and accurate data that is now available, coming from monitoring stations and model predictions and forecasts, contributes to informed decision-making in both the river basin and the coastal Gulf area. Database xe With a powerful framework in hand, HCMR and the region of Central Greece are now able to study the changes that occur in the area with ease, leading to optimal management and restoration practices.

The forecasting and monitoring capabilities of our solution enable authorities to plan mitigation measures and find the best ways to deal with emerging problems.

Readily-available information results in optimised and more efficient agricultural practices which translate to cost-savings for the local farmers.

As part of this research effort, the effects of climate and land use changes were also studied. Database yml mysql Scenarios were run to assess how changes in land use regimes, irrigation practices and climate would affect the river basin and coastal (Maliakos Gulf’s) water quality and quantity.

The sampling and monitoring data, flood forecasts and hydrological forecasts can be accessed by the public here and used by authorities. 5 database is locked A walk-through guide (in Greek) for the project website may be viewed here.
