. Direction of flow is determined by a least‐squares fitting of plane surfaces to measured water levels. The calculated coefficients yield the corresponding components of the gradient vector. The method can be implemented for two‐ or three‐dimensional flow using a spreadsheet program More than the minimum three or four measurements for two‐ or three‐dimensional flow can be included in the calculation. The method is flexible and easily tailored to particular field applications.
