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 Workshop - Apr. 3 -4, 2014 - Slide ‹#›

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*n 2 )/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 otis3: NWP=1 CF is constant (0.0025) 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) ADCIRC Workshop - Apr. 3 -4, 2014 - Slide ‹#›
