EROSION LANDFORM MODEL GENERATION DEVICE, EROSION LANDFORM MODEL GENERATION METHOD AND COMPUTER PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide a device and a method capable of generating an erosion landform model more accurately in a shorter time compared with a conventional method.;SOLUTION: The erosion landform of a natural landform formed by erosion by flowing water is reproduced. For example, an initial digitized landform model h (x, y, 0) is generated based on data of the natural landform corresponding to a real region R or on an artificial model generated based on random numbers or the like, and an erosion function parameter is calculated based on the generated model. An erosion landform model h (x, y, t) is generated based on the calculated parameter, to thereby enable to execute, accurately in a shorter time, transition prediction of the erosion landform based on a characteristic held by the natural landform corresponding to the real landform.;COPYRIGHT: (C)2003,JPO
