Hydrologic data collection in tidal estuaries

For predictive models, the optimum sampling interval and record length depend upon the frequencies at which significant variance is found. Estimates of spectral density, coherence, and phase relationships of stage, velocity, and salinity provide a basis for evaluating hydrologic data collection and...

Description
Summary:For predictive models, the optimum sampling interval and record length depend upon the frequencies at which significant variance is found. Estimates of spectral density, coherence, and phase relationships of stage, velocity, and salinity provide a basis for evaluating hydrologic data collection and utilization near the mouth of the Sacramento River. Here it was found that a 2‐hour sampling interval provided the essential data for engineering purposes. This interval is consistent with those found for the Potomac River estuary and for Raritan Bay, (Key words: Data; estuaries; pollution)
