The summary data in continuous simulation is listed in Table 10-5. Note that the average annual summaries may not be the average annual values if the simulation time period doesn’t cover the whole year.
TABLE 10-5 CONTINUOUS SIMULATION SUMMARY DATA
|P||mm||Average Annual Precipitation|
|Rain||mm||Average Annual Rainfall|
|Snow||mm||Average Annual Snowfall|
|*Snowmelt mm||Average Annual Snowmelt|
|ET||mm||Average Annual Evapotranspiration|
|INFIL||mm||Average Annual Infiltration|
|GWI||mm||Average Annual Groundwater Infiltration|
|Runoff||mm||Average Annual Runoff|
|Runoff Coef||-||Average Annual Runoff Coefficient|
|Peak Flow||m³/s||Peak Flow|
|Peak Flow Time||-||The Time when Peak Flow Happens|
Similar to single-event simulation, the summary data can be viewed in a table or with label as shown in the figure below. For continuous simulation, the summary data window is changed to Water Balance Result. Note that the water balance summary data is only available for catchments (i.e. NasHyd and StandHyd).
The water balance can also be summarized on monthly and yearly basis. To view the monthly and yearly water balance summary, choose the Water Balance menu from Schematic View context menu. The Water Balance window will appear as below.
On the left is the yearly and monthly water balance summary table shown in two tabs. Besides the summary data of each year and month, the average is also given at the bottom. For a month summary, a total summary is also available which basically is the average annual summary.
On the right side is a pie chart to highlight the three important water balance components: Infiltration, ET and Runoff. The chart is corresponding to the active summary data row in the summary table. To change to another summary data, click on the desired row or use the arrow key to move up and down. In this pie chart, default colors are used: green for ET, red for runoff and blue for infiltration. Note that the percentage in the pie chart is the percentage of the total of the three components. For runoff, it is not the runoff coefficient.
The water balance summary table can be for individual catchment or for all catchments. To show the summary table for individual catchment, select it before choosing the Water Balance context menu. For all catchments, deselect all objects before choosing the Water Balance context menu.
