GroMoPo Metadata for Amsterdam Water Supply model

Thr Amsterdam Water Supply has been using both the finite difference model MODFLOW (McDonald, M.G., Harbaugh, A.W., 1989. A modular three-dimensional finite-difference ground water flow model. Chapter Al, USGS, Book 6, Modeling Techniques) and the analytic element model MLAEM (Strack, O.D.L,, 1989. Groundwater Mechanics. Prentice Hall, Englewood Cliffs, NJ, (ISBN 0-13-365412-5); Strack, O.D.L,, 1999. Principles of the analytic element method. Journal of Hydrology, 226, 128-138) for many years. Choosing one or the other depends on the hydrologic system, its scale and the hydrologic features to be taken into account. Either method has its specific advantages. (C) 1999 Elsevier Science B.V.
