Embodiment 3
[0079] The present invention provides a possible maximum flood calculation method, before fitting the maximum flood peak flow and the corresponding catchment area point data, it also includes:
[0080] Obtain the flow data field of the maximum peak flow and the point data field of the catchment area point data;
[0081] Merge the flow data field and the point data field to obtain a field set;
[0082] Traversing and scanning the fields in the field set based on the field set and the preset phrase width to obtain field phrases;
[0083] Obtain the bit number of the field phrase, and calculate the frequency of occurrence of the field phrase in the same bit number;
[0084] Simultaneously, select the phrase that described frequency is greater than preset frequency as key field phrase, and obtain the start bit and end bit of described key field phrase;
[0085] Based on the start bit and the end bit, the bit width of the key field phrase is obtained, and the bit width is average...

[0122] Based on Example 1, in step 1, before collecting the possible maximum flood information related to the ultra-small watershed, it includes:
[0123] Get a collection of URLs that collect information on the largest possible floods associated with very small watersheds;
[0124] Perform a traversal search for each URL in the URL collection, and the filtering interface displays the first URL that has been accessed successfully;
[0125] At the same time, preprocessing is performed on each of the first URLs, and the second URLs are obtained by screening according to the preprocessing results;
[0126] Obtain interface information of a display interface corresponding to the second URL;
[0127] Obtaining the number of times the second website has been visited, the number of times it has been reported, and the user's evaluation information on the second website from the creation time to the current time;
[0128] inputting the interface information, the number of visits, the...
