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

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

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 ...

USE OF COPERNICUS METEOROLOGICAL DATA FOR THE PURPOSES OF HYDROLOGICAL MODELING

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

Show more

Floods are one of the most devastating hazardous events often causing destruction of infrastructure and loss of lives. In order to mitigate negative flood impact a reliable hydrological forecast is of great importance. Thus using trustworthy information on the meteorological elements that mostly contribute to the occurrence of floods - precipitation and temperatures, is essential. Although the accuracy of the global forecasting models like ECMWF, GFS etc. has improved a lot, still sometimes there are extreme meteo...
