What does "drainage design" refer to in irrigation systems?

• A. The planning of systems to improve irrigation efficiency
• B. The planning of systems to manage excess water levels
• C. The design of irrigation schedules
• D. The design of ornamental features in landscapes

Answer: (B)

Drainage design in irrigation systems specifically focuses on managing excess water levels. It involves creating systems that can effectively handle surplus water to prevent waterlogging and other issues that might arise when soil becomes saturated. Proper drainage is essential for maintaining the health of plants and the efficiency of irrigation systems. Excess water can lead to root rot and other diseases, negatively impacting crop yields. By effectively managing drainage, an irrigation system can ensure that plants receive the right amount of moisture while minimizing the risks associated with overwatering. Other areas mentioned, such as improving irrigation efficiency and designing irrigation schedules, while relevant to the overall irrigation system, do not directly pertain to the concept of drainage design. Similarly, ornamental features pertain to landscape aesthetics rather than the functional aspect of water management within irrigation.
