...Since absolute flood protectionis almost impossible,flood forecasting is the only chance to avoid catastrophe.
Introduction

Hydrological Information and Alarming
• Crisis Management Centre• Ministry of Agriculture, Forestry and
Water Management• Ministry of Ecology and Urban
Planning• Public and Media
Modernization
• With our NMM model weather prediction is on very high level, but for better water forecast we need modernization of our hydrological and meteorological network and hydrological forecast model.
