Computational Model of sDRIPS¶

The schematic flowchart below illustrates the decision logic, where execution pathways are determined by user-defined configuration settings. At a high level, the pipeline is composed of five sequential components:

1. Configuration setup (orange patch) – Reading and validating user-defined parameters from the configuration files. Here user also creates the ca_config.yaml.

   Note

   If sDRIPS is run in a canal-operator setting and command-area boundaries are unavailable, the cmd_config module can be used to generate a baseline structure of command areas. This process is iterative, and the resulting command areas may serve as approximations rather than fully accurate representations.

2. Evapotranspiration estimation (purple patch) – Computing crop water demand using Penman-Monteith and SEBAL models.

3. Percolation loss estimation (pink patch) – Quantifying percolation losses specific to field conditions.
4. Precipitation integration (blue patch) – Incorporating both nowcasted and forecasted rainfall from global models or local sources (only nowcast).
5. Advisory generation (green patch) – Comparing water balance components to produce net water requirement advisories.
