Determination of saturated hydraulic conductivity in high water table soils using a simple water table level measurement device

A simple water level indicator was developed for rapid evaluation of the sa turated hydraulic conductivity in soils with a high water table. Components of the observation wells and level indicators are readily available, durab le, and low-cost. The device was tested under field conditions using both f iltered and non-filtered wells, and results were compared with results from reference (parallel-drain) and laboratory methods. Data from filtered well s were close to those from the drain method. The device may also be used as a permanent water level indicator for field sites. Periodic inspection is generally the only maintenance that is required.
