Abstract: Improvements of river modeling 1D data preparation. The importance of
hydrographical networks data and the need for detailed studies do generate an
increase of projects in this specialized area and a diversification of river
mathematical modeling software. River mathematical modeling can be done in two
ways, namely; the "2D mode" and the “1D mode”. The “2D mode” is where a digital
terrain model of a full hydrographical basin must be produced and "1D mode" is
where only cross sections, long sections and structures elevations needs to be
presented in a graphical environment and in a specific formats for the
mathematical modeling software. This paper will show the principle of a custom
built GIS, specially created to help the preparation of 1D river modeling data.
The benefits are; elimination of human errors, automated processing, increasing
productivity, flexible output and cost reduction.
