One difficulty when conducting experiments is the selection of appropriate measurement techniques. Most of the current techniques can only capture a small portion of the area of interest and some of them are also intrusive. This study uses photogrammetry to determine the water elevation in a wide area representing a scale model of the Dahan creek in Taiwan, without perturbing the flow. In this work, steady flows over a fixed bed (without sediment transport) are investigated. Based on the obtained results, the capabilities and limitations of the photogrammetry in capturing the flow features are discussed. |
