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

Outputs

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

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
