  1. 1. Impacts of climate oscillation on precipitation and river flows of small scale river basins in Eastern Northeast Brazil

    Författare :Denis Duda Costa; Avdelningen för Teknisk vattenresurslära; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Eastern Northeast Brazil; Droughts; Floods; Climate patterns; Hydrological model; Weather radar;

    Sammanfattning : The Northeast region of Brazil is one of the most susceptible parts of the country to the effects of climate variability leading to severe droughts or extreme floods. Indeed, drought is a major issue due to a large semiarid area that covers 53% of the region, which determines the main climate characteristics of this region. LÄS MER

    Sammanfattning : This work represents an amalgam of a group of studies with the purpose of understanding the influence of the Pacific and Atlantic sea surface temperature on precipitation and river discharge in Northeastern South America. Sea surface temperature is a good representative of phenomena such as ENSO that, in turn, cause worldwide climate variability. LÄS MER

  4. 3. The cost of free water : Water resources allocation and use in the Curu Valley, Ceará, northeast Brazil

    Författare :Karin Kemper; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN;

    Sammanfattning : Despite enormous investments in water storage infrastructure over past decades, the Curu Valley in the semi-arid state of Ceara, Northeast Brazil, is subject to increasing water stress. This study explains the current situation in the valley and explores institutional alternatives for the achievement of more efficient water resources allocation and use. LÄS MER
