11 University of Oklahoma - School of Civil Engineering and Environmental Science ADCIRC Workshop - Apr , Slide 11 EC2012 Bathymetry

12 University of Oklahoma - School of Civil Engineering and Environmental Science ADCIRC Workshop - Apr , Slide 12 EC2012 Resolution

13 University of Oklahoma - School of Civil Engineering and Environmental Science ADCIRC Workshop - Apr , Slide 13 Mesh Comparison ec2001 ec2012

14 University of Oklahoma - School of Civil Engineering and Environmental Science ADCIRC Workshop - Apr , Slide 14 Mesh Comparison

15 University of Oklahoma - School of Civil Engineering and Environmental Science ADCIRC Workshop - Apr , Slide 15 Tidal Forcing TPXO 7.2 OSU Tidal Inversion Software (OTIS) 13 constituents (M2, S2, N2, K2, K1, O1, P1, Q1, Mf, Mm, M4, MS4, MN4) 1/4 ˚ resolution FES2004 Global Tidal Atlas 14 constituents available but only using 10 (M2, S2, N2, K2, K1, O1, P1, Q1, Mf, Mm) 1/8 ˚ resolution Sea Level Tide → FES global tidal model 20-day ramp, then extra 25 days before starting 365 days with harmonic analysis turned on, for 410 days total simulation

16 University of Oklahoma - School of Civil Engineering and Environmental Science ADCIRC Workshop - Apr , Slide 16 Preliminary Results TPXO 7.2 OTIS Forced with 13 constituents (M2, S2, N2, K2, K1, O1, P1, Q1, Mf, Mm, M4, MS4, MN4) ADCIRC parameters Version (started with and modified to write local harmonic (fort.5*) and hotstart files Δt=1.0 sec NOLI terms = tau0 = -1 (spatially varying but constant in time; it is calculated according to depth as follows: If the depth is >=10 tau0 is set to 0.005, if the depth is < 10, tau0 is set to 0.020) ESL=5 NWP=0

17 University of Oklahoma - School of Civil Engineering and Environmental Science ADCIRC Workshop - Apr , Slide 17 Version Modifications Problem: Harmonic Global Output using Writer PE’s memory issue – only problem with large grids too many constituents and stations – led to problems initializing the arrays for the elevation and velocities present on several computing architectures – TACC, OSCER, ERDC Solution: changed from global to local output – harmonics only works with hotstart files use –M option on the command line to write local files for harmonics adcpost required to develop the fort.5* files
