Alp-Water-Scarce Water Management Strategies against Water Scarcity in the Alps 4 th General Meeting Cambery, 21 st September 2010 Water Scarcity Warning System (WP8) DI Christian KOPEINIG Government of the Province of Carinthia, Department of Water Management, Klagenfurt, Austria 1

Aimes and Objectives 2 Situation in Italien and Austrian pilot sites is very different => two different early warning systems: - In the Italien pilotsite the focus is to reduce problems between agriculture (irrigation) and hydropower plant operators in the region of Veneto. - In the Austrian pilotsite we are working on a system to activate timely measures to enable a proactive drinking water management for expected drought periods Province of Carinthia Region of Veneto

Outputs 3 This solutions could be: - restrictions of car washing, irrigation for private gardens or filling pools - activation of additional wells for emergency supply - activation of distribution networks (communal or regional)

Model 7 The HBV model (Bergström, 1976, 1992) is a rainfall-runoff model, which includes conceptual numerical descriptions of hydrological processes. Snow routine Soil moisture routine Response function Routing routine
