Embodiment Construction

[0050] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0051] figure 1 It is a flow chart of a flood risk assessment method provided by an embodiment of the present invention. This method can be applied in a risk assessment system. The execution subject of this method can be a terminal, a server, or any device with data processing functions. The implementation of the present invention The example does not specifically limit this, and only uses the terminal as an example for illustration, such as figure 1 As shown, the method includes:

[0052] Step 101: When evaluating the watershed to be evaluated, determine the first storage path of the digital elevation model DEM data of the watershed, the second storage path of hydrological information, and the third storage path of land use informati...

Abstract

The present invention discloses a flood risk evaluation method and device, and belongs to the flood control and disaster mitigation technology field. The method is applied to a risk evaluation system,and comprises the steps of when a to-be-evaluated drainage basin is evaluated, using a terminal to determine a first storage path of the digital elevation model (DEM) data, a second storage path of the hydrological information and a third storage path of the land utilization information of the drainage basin in the risk evaluation system; obtaining the DEM data, the hydrological information and the land utilization information from the working space; according to the DEM data, determining the position area of the composition elements comprised by the drainage basin; according to the hydrological information, determining the flood characteristic data of the position area of the composition elements during a rainfall process; according to the DEM data, the flood characteristic data and theland utilization information, determining a damageable area in the drainage basin, and determining the danger grade of the damageable area, thereby evaluating the flood risk aiming at a community viathe risk evaluation system.

Description

technical field [0001] The invention relates to the technical field of flood control and disaster reduction, in particular to a flood risk assessment method and device. Background technique [0002] With the development of social economy, the economic losses caused by flood disasters are increasing. In developing countries, cities and towns are the political and economic centers of the region, and the economic value per unit of land is also higher, and the economic losses caused by floods to cities and towns are more serious. Once a town encounters a flood, the life and property safety of urban residents will be seriously threatened. [0003] A community is the basic unit of a town. The staff usually carry out flood prevention publicity in each community based on the flood risk of each community to improve the awareness of community residents on risk avoidance, thereby improving the town's flood control and disaster reduction capabilities. However, there is currently no co...
