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 $$Q(t < 9000) = 250 + \frac{750}{\pi}(1 - \cos{\frac{\pi t}{4500}})$$ $$Q(t >= 9000) = 250$$
