Expectations against the modelling practice of groundwater balance and resources

Tadeusz Macioszczyk


This paper examines recent utilization of numerical modelling in the analysis of hydrogeological water balance and resources. The equations for the now and mass transport of groundwater, that form the bases of the hydrogeological models algorithms are presented. The most frequent errors in modelling and in model documentation are discussed. The paper presents the requirements that should be met by properly built models of hydrogeological systems. The urgent need to issue quality certificates for the existing computer codes is a current issue in Poland. This paper proposes that these certificates would be issued by a joint team from The Commission of Hydrogeology (Polish Academy of Science) and from The Commission of Hydrogeological Documentation.
