With major rivers like the Elbe, the Rhine and the Donau criss crossing the country, Germany faces many water challenges. In the past few years floods occured due to a high water level of the rivers caused by heavy rainfall. 

German and Dutch authorities collaborate on water management in the border areas when it comes to issues like a high water level. In 2014 the Netherlands was the official partner country of the Hannover Messe, an annual trade fair for industrial technology. This years theme was 'globale challenges, smart solutions' and contained various water technology solutions.
