Abstract
Moisture content information in soil at a specified site is acquired. Moisture content information a ground surface within a given range that includes the specified site is acquired. An amount of runoff or storage volume of water on the ground surface or in a ground at a freely-selected site in the given range is calculated based on the moisture content information in soil and the moisture content information at the ground. A degree of risk of flood disaster at the freely-selected site within the given range is calculated based on the amount of runoff or storage volume of water on the ground surface. A point where there is the risk of flood disaster within the given range is determined and highlighted based on the degree of risk of flood disaster.
Claims6
A flood disaster prediction method comprising:
- acquiring moisture content information in soil at a specified site;
- acquiring moisture content information at a ground surface within a given range that includes the specified site;
- calculating an amount of runoff or storage volume of water on the ground surface or in a ground at a freely-selected site in the given range based on the moisture content information in soil and the moisture content information at the ground;
- calculating a degree of risk of flood disaster at the freely-selected site within the given range based on the amount of runoff or storage volume of water on the ground surface;
- and
- determining and highlighting a point where there is the risk of flood disaster within the given range based on the degree of risk of flood disaster.
A flood disaster prediction system comprising:
- at least one processing component configured to:
- acquire moisture content information in soil at a specified site;
- acquire moisture content information at a ground surface within a given range that includes the specified site;
- calculate an amount of runoff or storage volume of water on the ground surface or in the ground at a freely-selected site in the given range based on the moisture content information in soil and the moisture content information at a ground;
- calculate a degree of risk of flood disaster at the freely-selected site within the given range based on the amount of runoff or storage volume of water on the ground surface;
- and
- determine and highlight a point where there is the risk of flood disaster within the given range, based on the degree of risk of flood disaster.
A non-transitory computer-readable program recording medium storing a disaster prediction program, the disaster prediction program causing a computer to execute:
- processing of acquiring moisture content information in soil at a specified site;
- processing of acquiring moisture content information at a ground surface within a given range that includes the specified site;
- processing of calculating an amount of runoff or storage volume of water on the ground surface or in the ground at a freely-selected site in the given range based on the moisture content information in soil and the moisture content information at a ground;
- processing of calculating a degree of risk of flood disaster at the freely-selected site within the given range based on the amount of runoff or storage volume of water on the ground surface;
- and
- processing of determining and highlighting a point where there is the risk of flood disaster within the given range based on the degree of risk of flood disaster.
