Miotti, L.; Mroczek, E.K.; Hurst, A.W. 2010 Review of heat flow surveys at Whakarewarewa Lower Hutt, N.Z.: GNS Science. GNS Science report 2010/41 23 p.

Abstract: This report reviews the methodology of heat flow measurements relevant to geothermal fields where heat loss is through the soil, from water, water discharges and fumaroles. The history of geothermal utilization at Rotorua is discussed and previous heat flow studies at Whakarewarewa are reviewed. The work has been undertaken in preparation for a 2011 comprehensive field heat flow survey at Whakarewarewa to enable comparison to historical data and provide data to assess future changes. (auth)
