Land Use Management

A primary goal of environmental modeling is to assess the impact of human activities on a given system. Central to this assessment is the itemization of the land and water management practices taking place within the system. This section contains input data for planting, harvest, irrigation applications, nutrient applications, pesticide applications, and tillage operations. Information regarding tile drains and urban areas is also stored in this file.

In addition to the above, SWAT+ Editor groups the operations databases in this section of the editor. However, within the SWAT+ master watershed file (file.cio), these are listed under the ops section.

Land Use Management

This section is the entry point for management data in SWAT+. It comprises cross-walks to several other sections of data.

This data is accessed from the HRU properties section (hru-data.hru).

Management Schedules

Management schedules comprise auto-schedules (decision tables) and/or operations schedules.

When you import your project from GIS, SWAT+ assigns auto-schedules for management based on your crop land use.

For example, oats is a cold annual crop. If this crop is in your HRUs, a decision table named pl_hv_oats will be created based on the template of pl_hv_wwht when you import your data from GIS.

Adding/Editing a Schedule

From the management schedules section, click create a new record or click edit on a row in the table. Give your schedule a unique name.

To add an automatic schedule, start typing a decision table name in the box provided. Click the desired result from the list of matches that pops up, and click the add button. If you enter more than one schedule, you can drag and drop to sort.

To add an operation, click the add operation button. Select your operation type from the form that pops up and complete the remaining fields. Click save when done to add the operation to your table.

When you're done adding automatic schedules and operations, click the save changes button to save your management schedule.
