Sobre IBD

Flache, unbegrenzte Grundwasserleiter sind in vielen Ländern der Welt eine der wichtigsten Quellen für Trinkwasser und Bewässerung. Die Grundwasserverschmutzung durch Nitrat ist ein großes Problem in Gebieten mit intensiver landwirtschaftlicher Nutzung. In dieser Studie wurde ein zweidimensionales stationäres Modell für den Transport gelöster Stoffe entwickelt, um die Bewegung von diffusen Nitratverschmutzungsquellen in heterogenen porösen Medien zu simulieren. Es wurde ein Matlab-Code entwickelt, um die Grundwasserströmungs- und Stofftransportgleichungen mit Hilfe von Finite-Differenzen-Methoden zu lösen. Das vorgeschlagene Stofftransportmodell wird verwendet, um diffuse Nitratverschmutzungsquellen in einer landwirtschaftlich intensiv genutzten Region im Nordwesten Bangladeschs zu simulieren.
