Abstract


In this thesis, the National Natural Science Fund Project \integration, applied Hubei Bailianhe Valley. In this study, land surface hydrological model VIC, combined 1:1,000,000 National DEM data (1km ~ 2 grid resolution), land use, vegetation and soil classification and other geographical information to determine lotus river basin model parameters required to run VIC . Developed a bus module, coupled with the VIC model established Bailianhe Basin VIC land surface hydrological model; combining hydrological data, the model simulates the daily flow corresponding Hydrometric Station daily flow data are compared for the parameters and flow rate setting process simulation. On this basis, the WXGEN weather generator is integrated with the model, the use of WXGEN weather generator generates random meteorological data, the reservoir above Bailianhe things two tributaries (respectively down to make River Station, British Hill Station Controller ) flow processes and reservoir storage Bailianhe process was simulated. Full contents are: (1) The first chapter is an introduction, an overview of hydrological model, especially distributed hydrological models and land surface surface process model of development, research and application situation and existing problems and future research directions ; (2) The second chapter of GIS technology in the application of hydrological models introduced ArcView GIS software, focusing on the AvSwat module and the application of the modules of the corresponding GIS data were processed; Bailian River basin on the border of the basin extraction and sub-basins divided. (3) The third chapter is WXGEN weather generator and its application, review the weather generator research overview introduces WXGEN weather generator model, and the model is successfully applied to Bailian River Basin; (4) Chapter IV VIC land surface hydrological model is the theory and method introduced based on the mechanism of land surface hydrology VIC development process model and mechanism; (5) The fifth chapter is Bailian River Basin VIC land surface hydrological model and numerical simulation, the model introduced data preparation and numerical simulation, running step, the bus module, and WXGEN weather generator with Bailian River VIC land surface hydrological model integration; (6) The sixth chapter is the conclusions and recommendations, mainly on the text of the main research work and innovations a summary review, and pointed out the study, there are still problems and prospects for future work. In summary, this thesis Meteorology and Hydrology and Water Resources interdisciplinary way, the introduction of stochastic simulation of meteorological and hydrological model combined with the new method; which improve storm flood forecasting period and no observations or lack of hydrological observations forecast and so is a meaningful exploration.
