Numerical Simulation Of The Effects Of The Urbanization On The Ground Water

At present, with the growing of global urbanization, water problems become more prominent. Water problems constrain the urban construction and development. Groundwater, the only water source in many cities of the world, plays an important role in the development of urbanization. However, city urbanization breaks the balance between original human societies and nature, and the natural groundwater system is strongly interfered by human activities.Since the reform action of China and opening to the world, urbanization in China developed rapidly, especially, a great number of small cities spring up from the level ground like the mushrooms. The groundwater system has been changed because the continuous expansion of urban construction, housing construction, road construction with waterproof bituminous and underground engineering greatly altered the natural groundwater environment.The paper analyzes the effects of urbanization on hydrodynamic field, quality of groundwater, and the relationship between groundwater and urban Geological Hazards. In order to prove the theory, two cases of engineering projects areas are simulated to analyze the hydrodynamic field groundwater average caused by urbanization in terms of the groundwater level. Furthermore, the paper find that with the expansion of urbanization, the groundwater level declines; the groundwater level greatly has been changed in the regional landscape change, and in the area with water recharge, the groundwater level change a little. The paper also uses the settlement of groundwater level to estimate the amount of groundwater loss.The paper analyzes and simulates the relationship between urbanization and groundwater response, and provides a theoretical reference value for city planning, construction, and management.
