Summary

The heat-pulse flowmeter (HH) used in this testing is a KVA Model 200 system. The instrument computes groundwater vectors from heat arrival and decay in an array of four thermistors that surround a single heat source. An external compass attached to the top of the deployment system is used to orient the flowmeter in the borehole. The HH measured groundwater velocity and flow in the x-y plane. Fuzzy packers were filled with 0.08-inch diameter glass beads for all tests. The HH thermistors were centered over the simulated fracture during measurements. One to four measurements were made with the HH for each simulated flow.

Purpose

Groundwater flow is generally complex and difficult to characterize through rock units with substantial preferential flow pathways. Two borehole flowmeters capable of measuring horizontal flow rates and directions were evaluated in parallel-plate laboratory devices intended to simulate groundwater flow through a borehole that intersects a bedrock fracture in order to better understand the limitations and strengths of the two technologies. Measurements were made in wells with two diameters intersecting fractures with two apertures and multiple water flow rates.
