There is limited documentation on cost and time effective construction methods for large-scale rainfall simulators meeting ASTM D6459-19 specifications. By experimenting with the efficacy of various practices during the construction of twelve rainfall simulators in 2021 and comparing with other designs of various scope, this work seeks to establish a basis for overcoming the numerous challenges that accompany the task. Findings include that thick lumber is suitable for plot borders, French drains are effective at the bottom of slopes with sufficient grading, and surrounding bare soil should be protected. This work is key for refining standardization among large-scale rainfall simulators so that studies may be easily juxtaposed.
Learning Objectives:
Understand efficient techniques for efficient rainfall simulator construction.
Identify differences between small, intermediate, and large-scale rainfall simulators.
Understand the importance of standardization in the design and construction of rainfall simulators.
