Title:
RAINY WEATHER WATER INFILTRATION RATE ESTIMATION DEVICE, RAINY WEATHER WATER INFILTRATION RATE ESTIMATION METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2022/264422
Kind Code:
A1
Abstract:
Provided are a device, a method, and a program for estimating a rainy weather water infiltration rate by using an estimation model trained by machine learning. Provided is a rainy weather water infiltration rate estimation device for estimating rainy weather water infiltration rates that correspond to the proportions of rainy weather water infiltration amounts with respect to rainfalls and that are defined for a plurality of divisional areas in a target region, the rainy weather water infiltration rate estimation device comprising: a variable data acquisition unit that acquires data of variables which are defined for the respective areas and which include functions of precipitations in the areas; and a rainy weather water infiltration rate estimation unit that estimates rainy weather water filtration rates for the respective areas, by using the data of variables for the areas acquired by the variable data acquisition unit and an estimation model which is for estimating a rainy weather water infiltration rate from a variable and which is obtained through machine learning by using, as training data, past data of variables and rainy weather water infiltration rates.
