Module Statistics

Module Statistics calculates the following time statistics:

- arithmetic average;

- geometric average (optional);

- sample standard deviation from arithmetic average;

- sample standard deviation from geometric average (optional);

- maximum value;

- minimum value;

- accumulated value (optional).

- percentage of run-time below a critical value (optional).

It is better described in the support tool HDF5Statistics, but can be used in the MohidWater program.

Input file

The statistics configuration file can be configured using the following keywords:

METHOD_STATISTIC        : ... (statistical method: 1 = Values3DStats3D, 3 = Values2DStats2D;
                               1 = default)

GLOBAL_STATISTIC        : 0/1 (1 = calculate statistics for the whole time window period;
                               0 = default)
DAILY_STATISTIC         : 0/1 (1 = calculate daily statistics; 0 = default)
MONTHLY_STATISTIC       : 0/1 (1 = calculate monthly statistics; 0 = default)

SPECIFIC_HOUR_STATISTIC : 0/1 (1 = calculate statistics for data referring to a specific hour
                               of the day; 0 = default) 
SPECIFIC_HOUR           : ... (if SPECIFIC_HOUR_STATISTIC : 1, hour of day for statistics
                               calculation; 12 = default)

CRITICAL                : 0/1 (1 = calculate percentage of time below a critical value; 0 =
                               default)
CRITICAL_VALUE          : ... (parameter critical value, real; default = 0.02)

GEOMETRIC_MEAN          : 0/1 (0 = do not calculate geometric mean for non negative parameters,
                               1 = calculate geometric mean for non negative parameters;
                               0 = default)
ACCUMULATED             : 0/1 (0 = do not calculate accumulated values, 1 = calculate
                               accumulated values; 0 = default)

Hydrodynamic

Assign the following keywords to the hydrodynamic configuration file:

STATISTICS               : 1 
STATISTICS_FILE          : ..\..\GeneralData\Statistics\stats.dat

STATISTICS_2D            : 1 
STATISTICS_FILE_2D       : ..\..\GeneralData\Statistics\stats2D.dat

Note that there are two statistics files. One for the u, v and w components (3D fields). And another for the waterlevel (2D field). Make sure you define the correct statistical method in each case.

WaterProperties

Under each property assign the following keywords:

<beginproperty>
...
STATISTICS               : 1 
STATISTICS_FILE          : ..\..\GeneralData\Statistics\stats.dat
...
<endproperty>
