RUNOFF ANALYZER AND RUNOFF ANALYSIS METHOD
To provide a runoff analyzer and a runoff analysis method with which it is possible to obtain a runoff analysis result that is close to reality while using a simple analysis model.SOLUTION: A runoff analyzer 1 comprises a rainfall distribution input unit 101 and a runoff analysis unit 103. The rainfall distribution input unit accepts, as its input, rainfall distribution information for each mesh of an area being diagnosed. The runoff analysis unit calculates a retained quantity in each mesh on the basis of the rainfall distribution information. The runoff analysis unit calculates a hypothetical water level in a mesh where the retained quantity is less than the maximum retained quantity of a hypothetical conduit line, calculates a hypothetical water level in a mesh where the retained quantity is greater than or equal to the maximum retained quantity of the hypothetical conduit line and less than an upper-limit retained quantity that is the sum of the maximum retained quantity of the hypothetical conduit line and the maximum retained quantity of a hypothetical manhole, calculates a hypothetical water level in a mesh where the retained quantity is greater than or equal to the upper-limit retained quantity, and calculates various quantities needed for the evaluation of flooding risk in each mesh using the hypothetical water levels calculated in accordance with the retained quantities.SELECTED DRAWING: Figure 1
