The WEAVE-Apertif (WA) survey on the William Herschel Telescope will perform dedicated large integral field unit (LIFU; 90") optical spectroscopy follow-up of 400 HI resolved galaxies from the Apertif HI survey. The LIFU observations will provide an unprecedented study of galaxy evolution and dynamics with 3-6x the physical resolution and 2-3x the spectral resolution of previous IFU surveys, and will be well matched to the HI spatial resolution of Apertif (15"). The Apertif survey which will provide the parent sample, will survey ~4000 square degrees in the northern hemisphere in HI 21 cm with the Westerbork Synthesis Radio Telescope (see Adams et al "The Apertif Surveys: The First Six Months" at this meeting). One third of the WA galaxy sample will be chosen to be strongly morphologically disturbed in HI, one third will have kinematically disturbed HI disks, and one third will be an undisturbed control sample. The three subsets will span the color magnitude diagram in star formation rate and mass. The WA LIFU observations will achieve sufficient signal-to-noise in the stellar continuum to measure star formation rates, stellar age distributions, metallicities, ionized gas kinematics, as well as stellar kinematics and velocity dispersions. Here we present the survey plan and sample data quality based on recent survey operations rehearsals and realistic LIFU observation simulations.
