Average monthly dissolved oxygen levels in the waterways consistently declines from January to July/August each year and increasing trend is observed from August to December for each year. On the other hand, increasing trends in monthly average water temperature readings is observed from January to August and decreasing trend is observed from August to December for each year.

There was increasing trend in the average monthly Petroleum hydrocarbons readings from November 2010 to around February 2012 for Busarakhan, Somchair and Tansanee and an upwards trend from November 2010 to May 2012 for Chai and Kannika locations. After the upward spike in  2012, a decreasing trend was seen in the average monthly Petroleum hydrocarbons readings for all 5 locations around the same period.

Total hardness levels have been generally declining from 2009 to 2010, and the value of the readings are closer in range in 2010 as seen with the smaller IQR. The total hardness levels were lowest in 2011 and 2012. Increasing trends in the total hardness levels were observed for 2014 to 2016 and the first quartile (25th percentile) is also at a higher value in 2014 to 2016 compared to previous years. There were more highly skewed total hardness readings in 2014 to 2016.

The storyboard consists of 4 dashboards.


1st Dashboard
To identify the trends in the average chemical measure values and to analyse the distribution of the chemical measure values, by time and location. The filter options are Location, Year and Measure. Users can also further drill down at Year, Month or Day level for the line chart.

2nd Dashboard
To spot anomalies and unusual trends in the chemical measure values over time and across locations. The filter options are Location, Year and Measure. Users can also further drill down by Year, Month or Day level to analyse the average chemical measure values.

3rd Dashboard
The heatmap Calendar shows the number of records collected in each day across the years selected. The filter options are Location, Year and Measure.

4th Dashboard
This dashboard allows users to compare the trends in Average Measure Readings across locations and by years. The filter options are Location, Year and Measure. Users can also further drill down by Year, Month or Day level to analyse the average chemical measure values.
