A fast, efficient constant-head injection test (CHIT) for in situ estimation of hydraulic conductivity (K) of sandy streambeds is presented. This test uses constant-head hydraulic injection through a manually driven piezometer. Results from CHIT compare favorably to estimates from slug testing and grain-size analysis. The CHIT combines simplicity of field performance, data interpretation, and accuracy of K estimation in flowing streams.
本文提出了一种用于原位估算沙质河床水力传导率(K)的快速、高效的常水头注入试验(CHIT)。该试验通过手动驱动的测压管进行常水头水力注入。CHIT的结果与弹式试验和粒度分析的估算结果相比具有优势。CHIT结合了现场操作的简便性、数据解释以及对流动溪流中K估算的准确性。
