Table 1 Temperature vs. depth equations at gauged well locations by regression analysis

From: Assessment of subsurface temperature distribution from the gauged wells of Puga Valley, Ladakh

Well number Distribution function T(z) R 2
PGW 20 40.24 + 0.11 z 0.87
PGW 18 6.99 + 1.46 z 0.87
PGW 1 19.53 + 2.08 z 0.98
PGW 6 \( \frac{a + bz}{{1 + cz + dz^{2} }} \)
a = 24.26; b = 13.71; c = 0.121; d = 0.001

PGW 3 48.5 + 1.49 z 0.89
PGW 15 3.28 + 1.15 z 0.86
PDGW 45.69 + 1.14 z 0.92
Natural geothermal gradient 10.3 + 0.20 z 0.98
  1. Temperature field is in °C; z is the depth from surface in m
