Summary
Abstract: The Southern California Coastal Water Research Project (SCCWRP) is developing a
hydrodynamic model of the SGR estuary, which is part of the comprehensive
water-quality model of the SGR estuary and watershed investigated by SCCWRP and
other local agencies. The hydrodynamic model will help understanding of 1) the
exchange processes between the estuary and coastal ocean; 2) the circulation
patterns in the estuary; 3) upstream natural runoff and the cooling discharge
from PGS.

Like all models, the SGR hydrodynamic model is only useful after it is fully
calibrated and validated. In May 2005, SCCWRP requested the assistance of the
U.S. geological Survey (USGS) Coastal and Marine Geology team (CMG) in
collecting data on the hydrodynamic conditions in the estuary during the summer
dry season. The summer was chosen for field data collection as this was assumed
to be the season with the greatest potential for chronic degraded water quality
due to low river flow and high thermal stratification within the estuary (due
to both higher average air temperature and PGS output). Water quality can be
degraded in winter as well, when higher river discharge events bring large
volumes of water from the Los Angeles basin into the estuary. The objectives of
this project were to 1) collect hydrodynamic data along the SGR estuary; 2)
study exchange processes within the estuary through analysis of the
hydrodynamic data; and 3) provide field data for model calibration and
validation. As the data only exist for the summer season, the results herein
only apply to summer conditions.
