Spherical QTM-Based Submerged Simulation System of Sea Level Rise

Abstract

Abstract: Focused on the dynamic simulation of submerged area after the rise of sea level, key technical issues were discussed, such as data organization and scheduling in large-scale 3D scene, submerged area dynamic simulation based on the adjacent relations of QTM (Quaternary Triangular Mesh) grids. A submerged simulation system based on QTM was designed and developed using Visual C#3.0 programing language and Microsoft DirectX 9 graphic interface, and the overall structure and main function of the system were introduced in detail. Tianjin Binhai New Area was selected as study area for submerged area dynamic simulation under different sea levels. Results show that this system can provide efficient support for flood disaster warning of coastal area after the rise of sea level.

Key words: spherical quaternary triangular mesh (SQTM), sea level rise, adjacent relations of QTM, dynamic simulation
