This paper is a discussion and interpretation of the stratigraphical and pollenanalytical material presented by the author in Vol. II of this paper: "Description of sections and pollen-analyses - A presentation of the bog-geololical material".Eight pollen diagrams from the bog Aamosen are presented, covering Preboreal, Boreal, and early Atlantic periods.On the basis of the curves of the diagrams an attempt is made to elucidate the development of the vegetation in the area. The water-level in the basin is determined from the succession of sediments and from the pollen diagrams, and a possible alternation with the oscillations of the Littorina sea is pointed out.The climate development is discussed, and a climatic oscillation in the early Atlantic period is deduced from the courses of the curves for Hedera and Viscum.Finally the habitation at the Maglemose settlement Verup 5 in Aamosen is interpreted, and individual phases of it are pollen-analytically dated.

Numerical modeling of the problem of dam monitoring by the Electrical Resistivity Tomography method is carried out. The mathematical model is based on integral equations with a partial Fourier transform with respect to one spatial variable. It is assumed that the measurement line is located across the dam longitude. To approximate the shape of the dam surface, the Radial Basic Functions method is applied. The influence of locations of the water-dam, dam-basement, basement-leakage boundaries with respect to the sounding installation, which is partially placed under the headwater, is studied. Numerical modeling is carried out for the following varied parameters: 1) water level at the headwater; 2) the height of the leak; 3) the depth of the leak; 4) position of the supply electrode; 5) water level and leaks positions are changing simultaneously. Modeling results are presented in the form of apparent resistivity curves, as it is customary in geophysical practice.
