Abstract
The Water Division of Mott MacDonald Group developed and successfully used a powerful range of mathematical models for simulating unsteady flow and water quality parameters in rivers, lakes and estuarine systems. The graphic user interface (GUI) for the “HYDRO” suite of programs - ID and 3D packages was developed for this thesis. The GUI involve dialogue facilities and graphic reflection of objects and processes from the real world (reaches, nodes, water flows, floods, etc. ). For the mesh creation requirement in the Hydro-3D model existing methods of triangulation were observed and a mixed algorithm developed with its own implementation. The HYDRO models work with a large amount of data, such as bathymetry levels and water pollutants. For the inputting this data, different types of interpolation were studied and functions of linear and polynomial interpolation were developed. The platform for developing a code for the graphic interface was the C++ program language (Borland C++ Builder v. 5 compiler). In the Hydro-ID and Hydro-3D models, phases of creating the models have been highlighted: - defining location of data storage, creating model network; - preparing initial conditions of simulation, simulation processing; - post-processing results of simulation For these tasks, the main form and input forms, combined data storage and the variable output forms for visual interpretation of results were designed. In addition, for the purpose of communication with other application the export/import functions were designed. The object implementation in GUI provides flexible facilities to modellers for developing model networks. At the end of the simulation the results can be studied in statistical tabular form, on graphic charts and on background maps by colour gradient filling. Since the suite’s development in 1982, HYDRO models have been applied to over 150 schemes in more than 30 countries for the simulation of surface and underground water systems.
