Saturated buffers store water within the soil profile of field buffers, by diverting tile water into shallow laterals that raise the water table within the buffer and slow outflow.
Drainage water recycling is the practice of capturing excess water drained from fields, storing the drained water in a pond, a reservoir, or a drainage ditch, and using the stored water to irrigate crops when there is a water deficit.
Controlled drainage, also known as drainage water management, is the practice of using a water control structure to raise the depth of the drainage outlet, holding water in the field during periods when drainage is not needed.
The Transforming Drainage database at Iowa State University, managed by Lori Abendroth and Giorgi Chighladze, is one of the most notable outputs of this project. It brings together data from the team’s 42 research sites that span field- and plot-level scale experiments in an intensively standardized and quality controlled format. This database has supported the expansion of new and existing research questions and facilitated discussions around new insights into the planning, evaluation, and implementation of drainage water storage systems. At the end of the project, the team will make this data available to the public.
Transforming Drainage Team members provide drainage-related information through various sites hosted by college and organizations. Additional websites that provide information related to drainage management practices and drainage water recycling can also be found here.
