Digitized results from the California Water Olympics. The variables are as follows:

t The time (in seconds) since the start of the model run.

Q The flow rate [\(ft^3 s^{-1}\)].

x The distance downstream [\(ft\)] at which the hydrograph was recorded.

The data can be used to validate numerical solutions to flood wave routing for a channel
under the following conditions:

Channel width is 100 feet.

Channel slope is 0.001.

Channel extent is 150,000 feet.

Channel roughness (Manning's n) is 0.045.

Channel sideslope is 0 (rectangular channel).

Initial flow rate is 250 cfs.

Upstream boundary condition is defined as
$$Q(t < 9000) = 250 + \frac{750}{\pi}(1 - \cos{\frac{\pi t}{4500}})$$
$$Q(t >= 9000) = 250$$
