Rural Drainage & Irrigation System Design

I'm seeking an experienced professional to assist with the design of a rural drainage system. The key tasks include:

- Preparing a detailed list of design requirements for the rural drainage system, focusing on determining an acceptable return period for critical rainfall conditions.
- Conducting preliminary design work for both the drainage and irrigation systems. This will entail calculating design parameters, net irrigation requirements, and selecting appropriate equipment.
- Analyzing leaching requirements during irrigation to prevent salinization.

I also need a comprehensive analysis of calculation results under various rainfall conditions using SOBEK software.

The final deliverable should be a clear report detailing the design steps and results, alongside a proposed management and maintenance plan for the study polder.

I value efficiency above all in this project, so a strong background in maximizing system efficiency is a plus. Experience with SOBEK software and understanding of rural drainage systems is essential.
