<p>The present invention relates to an apparatus for measuring a differential head between underground water and stream water, which is capable of accurately and continuously measuring the level of the stream water. The apparatus comprises: a tube-shaped first pipe having an end installed to be inserted into the streambed, and having a first inner space in which the underground water forms a certain level when flowing into the first inner space; a tube-shaped second pipe having an end installed to touch the streambed, and having a second inner space in which the stream water forms a certain level when flowing into the second inner space; and a connection unit adjusting the height of the second pipe against the first pipe, and mutually connecting the first pipe and the second pipe so that the second pipe can be arranged to be vertically erected in the stream. Therefore, the apparatus is capable of being used on a study on the flow directions of water resources by measuring the heads of the underground water and the stream water accurately and collecting data on the heads continuously for a long time.</p> |
