Midvatten plugin for QGIS

A toolset for importing, editing and viewing observational data from hydrogeological investigations: drillings, water level measurements, water flow measurements, seismic data, VLF data, GPR data etc.

The toolset is distributed under the terms of the GNU GPL License v2.

The following tools are included:

• Database generator - generates an empty database of a predefined and recommended design
• Load Default Layers - default layers from database are loaded, symbology and custom edit forms together with edit form logics are defined
• Importing tools, import from csv files to the database:
  • observation points
  • observation lines
  • water level data (both manual measurements and automatic measurements from a logger)
  • water flow readings
  • water quality data (both from laboratory analysis and field measurements)
  • stratigraphy data
  • vlf data
  • seismics data
  • meteorological observations
• Edit tools:
  • Update obs_points coordinates from map position
  • Update obs_points map position from coordinates
  • Calculate water level in meter above sea level
  • Calibrate automatic water level measurements
  • Calculate average water flow from accumulated volume readings (from version 1.1)
• View plots:
  • Time Series Plot - Point-and-click to select observation points and have corresponding time series data plotted in a separate window - e.g. water level measurements in observation wells
  • XY Scatter Plot - Point-and-click to select e.g. seismic profiles and have the interpreted results plotted in a separate window
  • Stratigraphy plots - Point-and-click to select observation wells and have the stratigraphy plots in a pop-up window (This is a modified version of ARPAT-plugin with geo and hydro dictionaries stored in the python code. Those dicitionaries might be moved to domain tables in the database in the future.)
  • Section Plot - select a set of observation points in the obs_points layer and a vector line layer object - then get a 'profile'/section plot of stratigraphy data, water level, bedrock and ground surface from DEM etc
  • Piper Diagram - create a piper diagram from the selected set of observation points
  • Custom plots - any time series or scatter plot from the database (see announcement here)
• View reports:
  • General observation point report (a simple borehole log) - Point-and-click to select an observation point and get corresponding general information togheter with stratigraphy and water level statistics presented as a html report.
  • Water Quality reporting tool - Point-and-click to select water sampling points and have the corresponding water quality data presented as a html table report.
