1. A method for measuring fluid flow in a channel, comprising the steps of:

  • obtaining a probe having a height to width ratio of less than 0.52, wherein said probe height and width are positioned substantially perpendicular to the direction of the main fluid flow in said channel;

    obtaining a computing means having stored therein drawdown data for said probe;

    placing said probe in a channel where fluid flow is to be measured;

    determining fluid depth in said channel with said probe;

    correcting said fluid depth determination based upon said drawdown data using said computing means; and

    calculating fluid flow rate based upon said corrected fluid depth determination using said computing means.
