Measurements 910 January 2010 <br />
Weekend <br />
The last flow measurements were made from the 9 th of January to the 10 th of January 2010, during<br />
the weekend from Saturday to Sunday. The first measurements started at 12:00 a.m. on the 9 th of<br />
January <strong>and</strong> continued every second hour to 10:00 a.m. on the 10 th of January. This was the first<br />
flow measurement period with no rain <strong>and</strong> thus no significant flow peak connected to a rain<br />
event. From the afternoon on the 9 th of January the flow decreases gradually <strong>and</strong> in the evening<br />
the flow goes up distinctly. The influent flow reaches a maximum at 20:00 <strong>and</strong> goes thereafter<br />
down during the night. During the morning on the 10 th of January the flow increases slightly<br />
again. The behavior of the flow characteristics from this period can be seen in Figure 8.9.<br />
