Introduction

The APRIORA plugin is a QGIS tool divided in two groups:

The first group of tools is designed to estimate flow in normal and low condition in a catchment, while the second one calculate concentration of different Active Pharmaceutical Ingredients (APIs) and perform the risk assessment in each river section.

Getting Started

Please find instructions on how to install the plugin in the Installation for Windows section.

Support, contributing and testing

Please contribute using Github (link). Create a branch, add commits and open a pull request.

Reporting bugs or suggesting improvements

If you find a bug in the APRIORA plugin, please open a new issue (issues) and tag it “bug”. If you want to suggest a new feature or an improvement of a current feature, please open a new issue and tag it “improvement”. For both cases, you can always send an email to cristiano.guidi2@uni-rostock.de.

Latest changhes

This section contains the most recent changes and updates to the plugin.

  • v.1.0.0:

  • v.0.7.2: 7 - Accumulation is now compatible with polygon river networks. In the previous versions it was necessary to provide the river network as a multi-line shapefile. In the Finnish catchment with the Vemala model this caused some issues since the output of the hydrological model is a polygon shapefile. Because of this reason, the tool was adapted to accept polygon shapefile of the river network as input. Additionally, 8 - Risk Assessment is now compatible with polygon river networks too.

  • v.0.7.1: 5 - API parameter selection is moved from the menu toolbar to the processing toolbox like the other 7 tools. The output of monitoring point from 7 - Accumulation now contains also the accumulated load of APIs and not just the concentration values. The river layer output from 8 - Risk Assessment now contains the NET_ID column for each river section. This addition makes easier to identify the river sections at risk.

  • v.0.7.0: in 7 - Accumulation is not necessary anymore to provide “mean flow” and “mean low flow” values for the individual section, but only the accumulated value.

  • v.0.6.9: Fixed error in 6 - Emission Loads. When a new value was added in 5 - API parameter selection, algorithm had problems retrieving the new value and was referring to the original one. Now fixed.

  • v.0.6.8: Added function in 7 - Accumulation to calculate concentration of APIs at monitoring stations.

  • v.0.6.7: Accumulation function was not correctly distribute the flow to upstream and downstream sections after the split. The function was ordering the sections by river lengths. Problem fixed by ordering the sections by their NET_ID.

  • v.0.6.6: Consumption Selection tool changed name to 5 - API parameter selection. Added description to API emission tools.

  • v.0.6.5: update Consumption and Removal Rate dataset. Fixed some typos. Added compatibility for GEOS version < 3.10.

  • v.0.6.4: Fixed error: Feature (3) from “subcatchment_layer_copy” has invalid geometry.

  • v.0.6.3: Fixed error: object has no attribute ‘parameterAsStrings’.

  • v.0.6.2: Fixed typo in Consumption Selection tool.

  • v.0.6.1: Fixed connection between PNEC custom table and Risk assessment tool.

  • v.0.6: Risk assessment tool added to the set of available tools.

  • v.0.5.1: Added feature to customize input data of Consumption selection.

  • v.0.5: Accumulation tool developed.

  • v.0.4: API Emission set of tools is created. Consumption selection and Emission Loads developed.

  • v.0.3: Adaptation for transferability of Contributing area of gauging station, Calculate geofactors, Flow estimation to the new algorithm developed in v.0.3

  • v.0.2: Fix River Network is developed for transferability of Flow estimation in different catchments.

  • v.0.1: Flow estimation set of tools developed (Contributing area of gauging station, Calculate geofactors, Flow estimation), but working only for the German case study (Warnow).
