ASSESSMENT OF PEAK FLOW VARIATION DUE TO LANDUSE CHANGE: VIT RIVER CASE STUDY

(STEF92 Technology, 2023-10-01, Silviya Stoyanova, Valeriya Yordanova, Vesela Stoyanova)

Show more

The results of many research projects and studies report that landuse/ landcover change (LULCC) is a major driver of the changes in the hydrological processes within a watershed. Landuse induced landcover changes, e.g., urbanization, deforestation, have a direct impact on the hydrological regime of watersheds thus increasing their vulnerability to extreme hydrological events. In this research the Soil and Water Assessment Tool (SWAT) was used to study the landuse/landcover change impact on the hydrological dynamic...

COMPARISON OF NATIONAL, EUROPEAN AND BLACK SEA REGION FLASH FLOOD FORECASTING PRODUCTS FOR THE TERRITORY OF BULGARIA

(STEF92 Technology, 2023-10-01, Vesela Stoyanova, Georgy Koshinchanov, Silviya Stoyanova)

Flash floods occur in small areas and in a short time after an extreme precipitation event - generally less than six hours. The intensity of the precipitation, the location and distribution of the precipitation, the land use and topography, soil type, etc. determine just how quickly Flash Flooding can occur. These types of floods are extremely dangerous and it is very important to pay special attention to their forecasting. Due to the complex nature of flash floods, in addition to the qualification and experience ...

FLOOD HAZARD MAPPING TO PROTECT IMPORTANT HABITATS

(STEF92 Technology, 2023-12-15, Vesela Stoyanova)

Show more

Floods are one of the most devastating natural disasters that can lead to significant economic and environmental damage and even loss of lives. Flood hazard mapping is one of the measures of disaster risk reduction and becoming a more important function in conserving biological diversity and protected areas now and future. Most of the research is focused on determining flood risk in urbanized areas. In this paper, the protected areas affected by potential floods are studied. Protected areas are according to a dire...

NEURAL NETWORK-BASED MODELS FOR STRUMA RIVER FLOW FORECASTING

(STEF92 Technology, 2023-10-01, Snezhanka Balabanova, Vesela Stoyanova, Valeriya Yordanova)

Show more

Accurate river flow forecasting is an extremely important issue for proper management and optimal use of water resources as well as for warnings of extreme hydrometeorological events. Rainfall-runoff simulation is essential for short and longterm forecasting of the river discharge. Determining the relationship between rainfall and runoff is one of the most important tasks faced by hydrologists. This relationship is a nonlinear and extremely complex process influenced by many factors such as watershed topology, veg...
