LIMITATIONS OF BANK-STORAGE MODEL ASSUMPTIONS

Major alluvial aquifiers in the central United States have certain common characteristics. Sediment mean grain size and hydraulic conductivity both increase with depth. Furthermore, most modern major rivers do not fully penetrate the alluvium. Examination of the common bank-storage model assumptions and comparison with major alluvial aquifer hydrogeology indicates that many of these assumptions are questionable, and the resultant models may yield erroneous values. Common assumptions which do not correspond to observed data include the Dupuit-Forchheimer conditions and the assumptions of homogeneity, fully penetrating streams, and solely confined or unconfined systems. The limitations of bank-storage model assumptions must be clearly understood when attempting to understand hydrogeological processes or in making decisions based on model output. /Author/
