Abstract: Water has always been in demand on small islands. Traditionally, island communities have used a variety of approaches to address their water shortage like small reservoirs, wells, cisterns, etc. Among the various technics, the construction of stone weirs along the riverbeds of seasonal streams were of common practice. A number of small weirs were constructed in 1300 meters of Kavouropotamos stream (Paros Island), based on existing knowledge and experience from Naxos and Kythera islands. These green infrastructures increase water percolation and enrich the aquifer and at the same time provide water for the adjacent farmlands, while also help maintain water during the dry summer period, thus creating small biodiversity oases for flora and fauna. The significance of stone weirs for biodiversity and the aquifers will be shown through a monitoring process.
