Ladwig, Robert ; Furusato, Eiichi ; Kirillin, Georgiy ; Hinkelmann, Reinhard ; Hupfer, Michael (2018-02-10)

Lakes are known to be strongly affected by climate change as a result of their sensitivity to atmospheric forcing. The combined response of urban lakes to climatic changes and to urbanization of the catchment may be further altered by water quality management measures. We studied Lake Tegel in Berlin, Germany as a representative urban lake profoundly influenced by intense water management measu...

Increasing Evapotranspiration on Extensive Green Roofs by Changing Substrate Depths, Construction, and Additional Irrigation

Kaiser, Daniel ; Köhler, Manfred ; Schmidt, Marco ; Wolff, Fiona (2019-07-23)

Urban environments are characterized by dense development and paved ground with reduced evapotranspiration rates. These areas store sensible and latent heat, providing the base for typical urban heat island effects. Green roof installations are one possible strategy to reintroduce evaporative surfaces into cities. If green roofs are irrigated, they can contribute to urban water management and e...

Reassessing Hydrological Processes That Control Stable Isotope Tracers in Groundwater of the Atacama Desert (Northern Chile)

Scheihing, Konstantin W. ; Moya, Claudio E. ; Struck, Ulrich ; Lictevout, Elisabeth ; Tröger, Uwe (2017-12-26)

A collection of 514 stable isotope water samples from the Atacama Desert is being reassessed geostatistically. The evaluation reveals that adjacent Andean catchments can exhibit distinct δ18O and δ2H value ranges in meteoric waters, despite similar sample altitudes of up to 4000 m above sea level (a.s.l.). It is proposed that the individual topographic features of each catchment at the western ...

Geometric Refinement of ALS-Data Derived Building Models Using Monoscopic Aerial Images

Jarząbek-Rychard, Małgorzata ; Maas, Hans-Gerd (2017-03-16)

Airborne laser scanning (ALS) has proven to be a strong basis for 3D building reconstruction. While ALS data allows for a highly automated processing workflow, a major drawback is often in the point spacing. As a consequence, the precision of roof plane and ridge line parameters is usually significantly better than the precision of gutter lines. To cope with this problem, the paper presents an ...
