<p>PROBLEM TO BE SOLVED: To support the works of formulating a method of building soil mounds.SOLUTION: An information processing unit in this invention, is meant for formulating a method of building soil mounds which are built in the downstream side of a dam by use of sediment deposited in the upstream side of the dam, and comprises: a table, in which a first value representing the volume of soil used for building a soil mound and a second value representing the height of the soil mound are varied, and a third value representing the time required for the soil mound to flow down completely being calculated according to each combination of the first value and the second value is memorized in relation to the first value and the second value; an input reception part, where at least either of the soil volume, the soil mound height, or the time required for the soil mound to flow down completely is received; and an output part where a value corresponding to the input value with respect to an aspect different from the aspect for which the input value is given, is read from the table and is output.</p> |
