Description

According to the 1rst review of the River Basin Management Plan of North Peloponnes, the underground water system of Larissos river is bad. Human and agricultural use result in brackish underground water. Moreover, the underground water system has also been characterized as a vulnerable zone due to nitrate pollution.  The project combines the measures provided in the River Basin Management Plan (EL02) with the National Strategy for Climate Change Adaptation. The project  will: a) monitor the effects of climate change and overexploitation in the pilot area of ​​the underground water system of  Larissa river by:  creating a climate model for the pilot area, undertaking hydrogeological research for the precise delimitation of the brackish zone and the vulnerability of the coastal aquifer, creating a network for continuous monitoring of the quantitative and chemical status of the aquifer through installation of modern telemetry equipment in licensed drilling inside the underground water system and the pilot application of artificial enrichment. b) improve the qualitative and quantitative situation of the underground water systems by submitting proposals for the artificial enrichment and the protection zones of the underground water system. c) create a communication plan, a geoportal and a website for the publication of the results of the project

Summary of project results

The granular Ground Water Body of Larissos River in Peloponese is coastal and extends to the boundaries of the Municipality of West Achaia. According to the 1rst Revision of the  River Basin Management Plans, its condition is poor.Water is used for irrigation and human use and therefore the water body  appears salinization phenomena due to over-exploitation, The water body has also been classified as a vulnerable zone due to nitrate pollution from agriculture.

 

 

The University of Patras, in collaboration with the Decentralized Administration of the Peloponnese, Western Greece and Ionian Islands, monitored the effects of climate change and over-exploitation of water resources in the area of the Ground Water Body  of the Larissos River, in order to improve the qualitative and quantitative status of the Ground Water Body.

The project created a climate model for prediction of the water balance in the region,  Installed equipment for monitoring hydrological and hydrogeological parameters and applied a pilot artificial recharge in existing licensed drilling installations  of a permanent groundwater quality monitoring system in the pilot area and undertook a hydrogeological research on the
delimitation of the brackish zone and the vulnerability of the aquifer.

The project combines the measures listed in the River Basin Management Plans with the actions of the National Strategy for Adaptation to Climate Change that concern water resources.

The project achieved Improvement of  the qualitative and quantitative situation of the Ground Water Body of Larisos river. It managed to address the impacts of climate change and  the salinization in the region and finalized temporary protection zones of the Ground Water Body (GWB) of Larissos from salinization. Citizen and  farmers will benefit  from the results. Also, the results will be useful for the local water company .

The dissemination and exploitation of the results of the project will continue for at least 5 years from the closure of the project under the responsibility of the University of Patras. The results will also be exploited by the relevant Waters Directorate.
