Rainfall Runoff Simulation based on Dynamic Digital Terrain Model
Hydrological processes are complex and nonlinear dynamic processes. In recent simulation study, most of the processes are generalized and established on the base of ideal model in lump model and even in distributed hydrological model. In order to simulate rainfall runoff process, more deep exploration for its mechanism and efficient mathematic model for its description are both required. In this paper, concept of Dynamic Digital Terrain Model (DDTM) is presented. The main idea of DDTM is establishing a lot of calculation rules, which simulate characteristics of terrain surface process in some degree, by organization these rules, the complex and nonlinear process on terrain surface can be simulated. Hydrological rainfall runoff process is taken as a typical example to illustrate the principal of DDTM in the experiment. The result shows that its feasible to using DTM simulate terrain surface process.
