This study presents the development of tools for the sustainable thermal
management of a shallow unconsolidated urban groundwater body in the city of
Basel (Switzerland). The concept of the investigations is based on (1) a
characterization of the present thermal state of the urban groundwater body,
and (2) the evaluation of potential mitigation measures for the future
thermal management of specific regions within the groundwater body.
The investigations focus on thermal processes down-gradient of thermal
groundwater use, effects of heated buildings in the subsurface as well as
the thermal influence of river–groundwater interaction. Investigation
methods include (1) short- and long-term data analysis, (2) high-resolution
multilevel groundwater temperature monitoring, as well as (3) 3-D numerical
groundwater flow and heat transport modeling and scenario development. The
combination of these methods allows for the quantifying of the thermal influences on
the investigated urban groundwater body, including the influences of thermal
groundwater use and heated subsurface constructions. Subsequently, first
implications for management strategies are discussed, including minimizing further
groundwater temperature increase, targeting "potential natural"
groundwater temperatures for specific aquifer regions and exploiting the
thermal potential. |
