The convective heat transport describes the by the movement of the groundwater itself transported heat energy. Thus, the convective heat flow j_k is the heat energy which is transported via a considered cross-sectional area A transverse to the direction of flow per time unit. Taking into account the velocity v the convective heat flow can be described as follows:

With:

j_k = convective heat flow [W]

c_w = specific heat capacity of the fluid [Ws/(kg K) = J/(kg K)]

ρ_w = density of the fluid [kg/m³]

A = cross-section of flow [m²]

v = distance velocity [m/s]

T = temperature [K]
