The control unit 1500 can calculate the flood risk for the predetermined area.

The control unit 1500 can calculate the flood risk based on the variable information and the rainfall information corresponding to the predetermined zone. For example, when the predetermined area is Gangnam-gu, the control unit 1500 can calculate the flood risk based on the variable information and rainfall information corresponding to Gangnam-gu. Here, the pre-designated area may be one of the areas of eup, myeon, dong, ku, county, city and province.

<Formula 1>

In the equation 1, ln (Dis) is the flooding risk, C is a constant, x is a rainfall value, y is a terrain multiplier, z is an impervious rate, k is a vulnerable house, p is a reservoir capacity, t can be a time. The constants a, b, c, d, and e in Equation 1 can be arbitrarily determined by a regression analysis of each variable information and flooding risk for a predetermined area. The rainfall value may be a value obtained by multiplying the mm unit of rainfall per hour by the weight for the corresponding interval and the duration of the rainfall in units of the rainfall value, the terrain multiples, the imperviousness rate, The terrain factor is a value calculated by adding or multiplying the low zone ratio (%), the average slope, the drain pump amount (liters or tons) to the predetermined zone, and the impervious rate is the (%) Of the impervious area where rainwater can not penetrate.

The rainfall value may be a value included in the rainfall information information received from the weather server 3000 and may be a result value calculated based on the rainfall information. For example, the rainfall value may be a weighted rainfall that gives a weight to the rainfall per hour by a rainfall interval, and adds an additional weight to the occurrence time.

Table 1 below is a table showing an example of weighted rainfall.

Seogang Ward section weight Time of occurrence score 5mm <= x <20mm 0.002 3 0.006 20mm < = x < 40mm 0.032 One 0.032 40mm < = x < 50mm 0.402 2 0.804 50mm <= x <80mm 0.803 One 0.803 More than 80mm 3.870 One 3.870 Weighted rainfall 5.515

As shown in Table 1, the controller 1500 may assign a weight to each of the sections of the rainfall that is the rainfall per hour, and may calculate the multiplication according to the duration of the section as a score. Also, the sum of the scores for the entire rainfall time can be calculated as the rainfall value at the time of weighting. Here, the rainfall is the total rainfall divided by the total rainfall time, and each interval may be divided by the user. In addition, the weight can be a non-standardized coefficient value calculated by regression analysis based on the rainfall intensity and the occurrence of rainfall.

More specifically, for example, the control unit 1500 calculates a weight of 0.002 in a time zone of 5 mm <= x <20 mm, a weight of 0.032 in a time zone of 20 mm <= x <40 mm, We can assign a weight of 0.402 to a section of 50mm <= x <80mm and a weight of 3.870 to a section of 0.803 or more. The value of each section is multiplied by the occurrence time of each section, .

In the above description, it has been described that the weighted rainfall amount is calculated and applied to the rainfall value based on the rainfall intensity, but the present invention is not limited to this, and various values can be calculated based on the information included in the rainfall information. For example, the control unit 1500 can calculate the weighted rainfall amount based on one rainfall included in the rainfall information, and apply the rainfall value to the rainfall value.

The terrain multiples may be a value based on at least one of an average of the elevation of the predetermined area, an average of the gradient, and a ratio of the lower elevation to the elevation of the predetermined area of the entire area of the predetermined area.

The impervious rate can be a value based on at least one of the ratio of the area of the predetermined area to the area of the urbanization land, the area of the land area, the weighted value according to the impervious rate per land cover, have.

The error constant and constant may be a predetermined value, i may be a symbol for identifying a predetermined area, and t may be the time at which the rainfall lasted.
