Version 51.06 Modifications
• Problem: Global harmonic output
• memory issue –problem with large grids, numerous constituents
• 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 – harmonic and hotstart
• use command line options
• –M write local files for harmonics
• –S write local hotstart files
• –R read local hotstart files
• adcpost required to develop the global fort.5* files

ADCIRC Bottom Friction Options
• NOLIBF
• 0 – linear bottom friction
• 1 – quadratic function of depth averaged velocity
• NWP – nodal attributes in fort.13
• quadratic_friction_coefficient_at_sea_floor
• mannings_n_at_sea_floor (converted to equivalent quadratic friction
coefficient)
• CF(t) = (g*n2)/cuberoot[depth+WSE(t)]
• Upper limit – CF value from fort.15

Basic ADCIRC Options
• Tidal forcing: TPXO 7.2 OTIS
• Forced with 13 constituents (M2, S2, N2, K2, K1, O1, P1, Q1, Mf, Mm, M4,
MS4, MN4)
• ADCIRC parameters
• Δt=1.0 sec
• NOLI terms = 1 2 1 1
• 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
otis1: NWP=0
CF is constant (0.0025)
otis3: NWP=1
VDatum CF
otis4(5): NWP=1 Mannings n (90% Mannings n)
• Run a 20-day ramp for tidal spinup, then run another 25 days before start
harmonic analysis for last 365 days (410-day total run)

Error Measures
• Mean absolute error: amplitude and phase
• RMS: Ae = (0.5 Am2 + 0.5 Ao2 – AmAo cos(ho-hm))1/2
• Relative RMS: Ar = Ae/Ao

Ongoing Work
• Project wrapping up but…
• Additional runs
• FES2012 with constant CF (for comparison)
• Increased Manning n (110% - for sensitivity)
• Modified VDatum CF in Chesapeake Bay and NY Sound

West Coast Summary
• Grid development is ongoing
• Add SE Alaska when done
• Fill in region of BC?
• Next steps:
• Collect input files from original VDatum and Foreman
meshes
• Begin building global input files
• Verify location of CO-OPS stations for input file
• Debugging…
