[ Time: 0 ] // Time of this record in years 0, 0 // Subsidence is zero at the origin 100000, -.2 // and increases to -.2 m/y at 100km [ Time: 100 ] // The second record is at 100 years 0,0 100000, -.1
If the file contains only one record, then the subsidence rate is held constant starting from the time indicated in the record header. If the model runs longer than the time of the last record, the subsidence curve is set to that of the last record for the remainder of the simulation.
The file begins with two 32-bit integers that define the size of the subsidence grid for each record. The first value is the number of rows and the second the number of columns.
Records are then listed one after another. Each record begins with a double value that gives the time in years of the record. The subsidence data then follows as double values written row by row. Subsidence values are given in meters per year.
The byte order of the file must be the same as that of the machine that the simulation will be run on.
