Standard Practice for (Field Procedure) for Constant Drawdown Tests in Flowing Wells for Determining Hydraulic Properties of Aquifer Systems
Also Known As:
ASTM D5786-17 is a standard practice that outlines the field procedures for conducting constant drawdown tests in flowing wells to determine the hydraulic properties of aquifer systems. The practice involves controlling the drawdown and measuring the discharge rates and head to analyze the aquifer's hydraulic properties.
The standard highlights the importance of competent personnel, suitable equipment, and appropriate facilities for obtaining reliable results. It references Practice D3740, which provides criteria for evaluating the competence and objectivity of testing, sampling, and inspection agencies. However, compliance with Practice D3740 does not guarantee reliable results, as other factors also play a role.
The practice is used in conjunction with analytical procedures such as those of Jacob and Lohman, and Hantush. These analytical procedures provide additional guidance for analyzing the hydraulic properties of aquifer systems.
