- ... Many agricultural soils are tile drained in order to lower water tables and improve crop production, but tile drains have a large impact on water flows and nutrient transport. The objectives of the study were to assess modelling requirements for describing shallow groundwater and tile drainage dynamics and to evaluate how tile drains affect groundwater flow across the redox interface, where nitrat ...

- ... The coincidence of two or more extreme events (precipitation and storm surge, for example) may lead to severe floods in coastal cities. It is important to develop powerful numerical tools for improved flooding predictions (especially over a wide range of spatial scales - metres to many kilometres) and assessment of joint influence of extreme events. Various numerical models have been developed to ...
