<p>Using the Hooghoudt
equation and measured water table depths, together with linear regression
method, a long-term drain flow record for a controlled drainage (CD) experiment
at the Davis Purdue Agriculture Center was constructed. </p>
<p><b> Site description:</b> The Davis Purdue Agricultural Center
(DPAC) is a research farm in eastern Indiana. The controlled
drainage experimental site is the 0.16 km<sup>2</sup> field split into four
quadrants, northwest (NW), southwest (SW), northeast (NE), and southeast (SE)
with areas of 3.5 ha, 3.5 ha, 3.6 ha, and 3.7 ha. This field has a slope
of less than 1%. Soils at the site consist of Blount (somewhat poorly drained),
Condit (poorly drained), Pewamo (very poorly drained) and a small portion of Glynwood
(moderately well drained) series. The drainage system was installed in 2004. Laterals
have an approximate depth of 1 m and spacing of 14m. Drainage in the SE and NW
quadrants was controlled during some periods while the SW and NE were allowed
to freely drain at all times. A more detailed description of the methods can be
found in Saadat et al. (2018).</p><br>
