Future climate scenarios of the Global Circulation model (GCM) show an increased frequency of heavy rainfall events, which may lead to more severe floods. It is also expected that more and more areas will suffer due to flooding as a result of growing urbanization. Public attention has increased in many parts of the world in recent years and calls have been made to improve flood warnings, including the United States, the European Union and Australia (Hapuarachchi, H.A.P, and Q.J. Wang 2008). To respond and manage f...

FLASH FLOOD FORECASTING USING FLASH FLOOD GUIDANCE SYSTEM PRODUCTS

(STEF92 Technology, 2022-11-15, Valeriya Yordanova, Silviya Stoyanova, Snezhanka Balabanova, Georgy Koshinchanov, Vesela Stoyanova)

Flash floods are defined as rapidly developing extreme events caused by heavy or excessive amounts of rainfall. Flash floods usually occur over a relatively small area within six hours or less of the extreme event with quite a rapid streamflow rise and fall. Increased occurrence of flash flood events is expected due to climate change and increase in extreme precipitation events [1]. Flash flood forecasting is still a challenge for hydrologists and water professionals due to the complex nature of the event itself. ...

FLOOD HAZARD MAPPING USING TWO-DIMENSIONAL HYDRAULIC MODELING RESULTS

(STEF92 Technology, 2022-11-15, Vesela Stoyanova, Snezhanka Balabanova, Georgy Koshinchanov, Valeriya Yordanova, Silviya Stoyanova)

Floods are one of the deadliest natural disasters in the world. According to the World Meteorological Organization (WMO), this is a consequence of the increasing frequency of heavy precipitation, changes in upstream land use, and a continuously increasing concentration of population and assets in flood-prone areas [1]. For this reason, flood prevention, and protection are a growing priority these days. Flood hazard mapping is a state-of-the-art tool for decision-makers and stakeholders when it comes to flood prote...

HYDROLOGICAL FORECASTING AND ACTIVITIES IN BULGARIA IN THE FRAMEWORK OF THE DAREFFORT PROJECT

(STEF92 Technology, 2022-11-15, Snezhanka Balabanova, Silviya Stoyanova, Vesela Stoyanova, Georgy Koshinchanov, Valeriya Yordanova)

Floods are the most frequent and widespread natural disasters worldwide (WMO, 2013). In 2006 for instance, exceptionally high river levels caused loss of lives and considerable economic losses in Serbia, Bulgaria and Romania. Thus risk prevention strategies were reconsidered and the need for common solutions for the Danubian countries was outlined. Non-structural measures to mitigate flood risk as is the improvement of forecasting capabilities on a basin-wide scale are known to be highly effective. The DAREFFORT p...
