One important factor in dealing with HC surface and ground water supplies is the differences in surface water flow and tributary ground water flow. In Nebraska, for example, stream-flow may move twenty-five miles per day or more, whereas ground water flow may be 300 feet per year.hen the aquifer is, say, twenty feet higher than the stream, the ground water will flow toward the stream more quickly than if the aquifer is only one foot higher than the stream.
