General notes

Welcome to Shiny Wetlandia --- possibly the greatest Wetland app ever created...

The Project

Wetlandia aims to improve how constructed stormwater wetlands function.

In the first phase, we are trying to predict pollutant removal performance using simple indicators like vegetation cover and aspects of the water level regime.

Feedback

Please get in touch with Chris Szota if you have any issues or ideas on how to improve the site.

Mapboard

The Mapboard takes a little while to load but creates an interactive map. You can switch layers on and off.

The large shapes are catchments for sites currently being sampled. Only study sites are shown, colour-coded by size of the waterbody/feature.

The blue points represent Melbourne Water rain gauges and show cumulative rainfall totals since the start of the study.

State of the Wetlands

This section gives an overview of the study sites, including benchmarking their status and performance according to the wetland design manual or relevant trigger values for pollutants.

Analysis

The analysis section relates predictor variables such as water level and vegetation cover with water quality variables.

Relationship between median water level and vegetation cover

Each point represents a wetland

Inlet/outlet paired samples across all sites

Each point represents a paired sample. Points below the 1:1 line indicate the concentration at the inlet was higher than the concentration at the outlet.

Vegetation cover vs. Removal efficiency (RE = ((inlet-outlet)/outlet)*100

Each point represents a wetland. A removal efficiency >0% indicates the outlet concentration was less than the inlet; whereas a removal efficiency <0% indicates the outlet concentration was greater than the inlet.

Outlet median water level vs. Removal efficiency (RE = ((inlet-outlet)/outlet)*100

Each point represents a wetland. A removal efficiency >0% indicates the outlet concentration was less than the inlet; whereas a removal efficiency <0% indicates the outlet concentration was greater than the inlet.

Water level

Water level data is pretty large, so it will take a few moments to load each time you change site.

Don't worry about offsets between loggers just yet, focus on the outlet series to get an understanding of water level.

Time series

Lines represent water level sensors with colour showing location.

Symbols reprsent sampling events and manual level checks

The bars represent cumulative rainfall for each event.

Exceedance curve

Median relative water level

Check 2 in the MUSIC Auditor suggests using the median relative water level (referred to as the effective normal water level) to identify wetlands with low hydrologic effectiveness. Based on Robertson et al. (2018), we consider wetlands with a median relative water level >100 mm above the design water level to be at risk of vegetatation loss.

These plots allow a site-by-site comparison of inlet and outlet concentrations.

Site analysis

These log-log plots hopefully show a pretty consistent offset between inlet and outlet concentrations which we can use to simulate treatment performance and loads over longer timeframes.
