Result Visualization

What is it?

Result Visualization interface allows users have more control over how figures are created and displayed. Users can create 1-D and 2-D plots for subbasin, reach and HRU outputs. Created 1-D maps are displayed as separate figures, and 2-D maps are overlayed over the google map. Users can select classification method, number of classes and color scheme for 2-D maps. In addition to outputs, users can also plot the and overlay input parameters. Map display option allows users to hide/show 2-D maps and markers. Watershed level plotting option allows users to create plot for watershed level output parameters and water balance. User can also download important input/output files and other optional output files.

How to use it:

Plot subbasin/reach time series data

Time series subbasin/reach data can be plotted by selecting data type, subbasin/reach number and plot parameter.

Parameter selection
Vizswatplotsub

1. Select data type: subbasin or reach. When selection is made, available parameters are updated.
2. Select subbasin/reach number.
3. Select parameter to plot.
4. Select time period. By default, entire simulation period is selected. If users want to plot selected time period only, a different time period can be selected.
5. Once plotting parameter and time period is selected, click "Plot" button.
A time series plot is created for the selected parameter and time period.

Plot average subbasin/reach values

To plot the average values for each subbasin/reach for the whole watershed:
1. Select data type (subbasin/reach) as shown in the figure above.
2. Select parameter as shown in the figure above.
3. Select time period as shown in the figure below.
4. Select plot type. Users can either plot average daily (monthly) values for the whole simulation period, or average values for specific month.
5. Select classification type. By default, the classification method in Natural Breaks.
6. Select number of classes. By default, the number of classes is five.
7. Select color shceme. By default, the color scheme is rainbow.
8. Click "Plot" button.

A new 2-D map is created and overlayed on to the Google map.

Plot input parameters

To plot subasin input parameters, select parameter under "Plot subasin input parameters" and click "Plot". Classification method, number of classes and color schemes can also be selected.
To plot HRU input parameters, select parameter under "Plot HRU input parameters" and click "Plot". Classification method, number of classes and color schemes can also be selected.

Plot watershed level data

To view watershed plotting options, click "Plot watershed data" button. The button expands and the options are visible.
To plot watershed level data, select parameter to plot, and click "Plot" button. The output figure is either a time seris plot, a bar chart or a pie chart.

Plot water balance maps

To create water balance maps, click on 'Plot water balances'. The menu expands.

The water balance maps can be created for either a subbasin or for the entire watershed. To plot water balance for the entire watershed, select 'All' as subbasin/reach. For plotting water balance for a particular subbasin, select the subbasin.

Daily, monthly, yearly, average monthly and overall water balance plots can be created. The water balance maps are created for overland flow, shallow aquifer, deep aquifer, streams, ponds/wetland and reservoirs (if available). "Overall" option also creates a Sankey diagram that show the water dynamics of the whole watershed.

In addition to the water balance plot for the entire period, a number time series plots can be created at selected intervals. To create such time series plots, select number of years of each interval.

The plots can be created either for the whole simulation period or for select period. To plot a different time period, select different values of from and to fields.

Please remember, the intervals start from the start day of the plotting. If the plotting start day is 10/25/2010, one year interval will be 10/25/2010-10/24/2011, and so on.
Click 'Plot' to create plots.

Plot flood maps

To create flood map, click on 'Plot flood map'. The menu expands.
Three types of flood maps can be created: flood hazard index, flood frequency and flood recurrance. A subbasin is considered flooded if the actual depth of water in a stream exceeds the channel depth. This comparison is done by extracting the actual water depth from the output.dep file with the channel depth from chan.deg file.
Flood hazard index is calculated by dividing the number of flood days with total number of days in each subbasin. The indices are categorized into five groups (very low, low, medium, high and very high) using equal interval method and plotted. Users can select the color ramp but the category are fixed.
Flood frequency map is created by counting the number of flood days and categorizing them using user selected method and classes and plotted.
Flood recurrance maps are created using user selected return period and distribution method. Gumbel and Log-Pearson Type III method are available for calculating the water depth for the given return period. If Log-Pearson Type III method is selected, users also need to provide regional skew coefficient and variance of regional skewness. Regional skew coefficient for the US can be obtained from the map provided by Oregon State University. Variance of regional skewness for the US is 0.302.
Users can either create plots for the entire simulation period or for the selected period.

Download files

To view files downloading options, click "Select files to download" button. The button expands and the options are visible.
Check all the boxes next to desired file. A list of optional output files also appear in the list if they were selected prior to simulation. Once selection is done, click "Download" button. Selected files are downloaded as a zip file.
