Hydrodynamic and Oil Spill Modeling: Corpus Christi Bay
Simulations presented on this web page show the speed and direction of water movement, i.e., currents, in Corpus Christi & Nueces Bays, and include a part of Aransas Bay. Currents are shown for a moving three-day window (beginning yesterday and finishing tomorrow) and slide forward each day. Flows are computed for about four weeks prior to today and extend through about a week beyond today, but only results for a three-day window are shown.
Corpus Christi Bay (Updated: 08:07 CDT May 13, 2013) Models are run and updated daily.
Model Input and Related Data
Tides
Data from the Bob Hall Pier station (TCOON Station 014) of the Texas Coastal Ocean Observation Network (TCOON) is used to estimate tides for Corpus Christi Bay. Model input for tides is composed of the most recent daily tide measurement plus forecasted tides, which are adjusted according to recent tide data. Tidal inputs are applied to the model's Gulf boundary to drive TxBLEND simulations. Comparisons between the measured tides and the hindcasts/forecasts are shown on the TWDB Tide Forecasts for Texas.
Wind
Wind velocity input used in the TxBLEND hydrodynamic model is derived from the NAM Model of the National Centers for Environmental Prediction (NCEP) by Texas A&M University Oceanography Department in cooperation with the Texas General Land Office (TGLO). The specific wind time series is calculated for the Corpus Christi Bay grid node at Latitude/Longitude: 27.800° N, 97.187° W. Wind plots show the hindcast/forecast wind speed and direction that is input into TxBLEND.
River Inflows
Inflows to the Corpus Christi Bay TxBLEND model are based on mean daily gaged inflows for the Nueces River and Oso Creek, the only two significant streams flowing into the bay. Ungaged flows are not estimated for this model simulation.
