Slow pools absolutely exist, as wave drag is the major impediment to speed and contributes about 55% of total drag. A shallower pool has more reflected wave energy in all directions. 2m is very shallow for a competition pool. This paper does a decent job of modelling how swimmers move through water: https://royalsocietypublishing.org/doi/epdf/10.1098/rsif.2018.0768 https://royalsocietypublishing.org/doi/epdf/10.1098/rsif.201...
