    Sammanfattning : Flooding is of great concern world-wide, causing damage to infrastructure, property and loss of life. Low-income countries, in particular, can be negatively affected by flood events due to their inherent vulnerabilities. Moreover, data to perform studies for flood risk management in low-income regions are often scarce or lacking sufficient quality. LÄS MER

  3. 2. Flood Prediction in data-scarce basins : Maximising the value of limited hydro-meteorological data

    Författare :José Eduardo Reynolds Puga; Sven Halldin; Chong-Yu Xu; Jan Seibert; Thomas J. Grabs; Vazken Andréassian; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Floods; data scarcity; value of information; rainfall-runoff modelling; regionalisation; rainfall-forecasts; event-based calibration; climatological day; discharge day; temporal resolution; modelling time-step.; Databrist; flödestoppsbaserad kalibrering; högflöde; informationsvärde; klimatologiskt dygn; nederbörds-avrinningsmodell; modelltidssteg; regionalisering; regnprognos; tids-upplösning; vattenföringsdygn; översvämning.; Inundaciones; falta de datos; valor de información; modelos lluvia escorrentía; regionalización; pronósticos de lluvia; definición del día; resolución temporal; paso de tiempo.;

    Sammanfattning : Floods pose a threat to society that can cause large socio-economic damages and loss of life in many parts of the world. Flood-forecasting models are required to provide simulations at temporal resolutions higher than a day in basins with concentration times smaller than 24 h. LÄS MER

  4. 3. Geographical Distribution of Disasters Caused by Natural Hazards in Data-scarce Areas : Methodological exploration on the Samala River catchment, Guatemala

    Författare :Agnes Jane Soto Gómez; Veijo Pohjola; Allan Rodhe; Giuliano di Baldassarre; Günter Blöschl; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; natural disasters; Guatemala; data-scarce areas; natural disaster science methods; natural disaster maps; Geovetenskap med inriktning mot naturgeografi; Earth Science with specialization in Physical Geography;

    Sammanfattning : An increasing trend in both the number of disasters and affected people has been observed, especially during the second half of the 20th century. The physical, economic and social impact that natural hazards have had on a global scale has prompted an increasing interest of governments, international institutions and the academia. LÄS MER
