How does terrain affect irrigation methods?

Steep slopes can significantly influence irrigation practices because gravity affects water movement and distribution. When dealing with hilly or mountainous terrain, water can flow too quickly down slopes, leading to erosion and uneven distribution of moisture. To mitigate these issues, farmers often employ terraces, which are steps that reduce the speed of water flow and help retain soil and water at various levels. This method helps in managing water resources effectively, ensuring that crops receive adequate hydration while minimizing runoff and soil degradation. Understanding the terrain allows for the design of irrigation systems that can better support agricultural productivity and sustainability.
