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 CHTT combines simplicity of field performance, data interpretation, and accuracy of K estimation in flowing streams.
