These resources summarize the results of two years of applied research into the effectiveness of various drainage management practices in Delta, including modelling for increasing precipitation challenges into the future. The project included a two-year trial on a field in Delta with known drainage and salinity problems to demonstrate and evaluate the benefits of various drainage management practices. The project sampled and monitored 26 fields across Delta with different drainage systems for vegetable and blueberry crops. This field data was then used to set parameters for and validate both field and landscape level digital soil maps and a drainage model. These were used to predict soil workability for expected future rainfall patterns.

In addition to the full project report and executive summary, four research summaries cover the project’s key findings:

  • The evaluation of drain spacing and ditch pumps in existing drainage systems
  • The prediction of water content in soil and number of workable days using DRAINMOD model
  • The impacts of tile drain cleaning over one year
  • Digital soil mapping of soil workability
