Estimates of water partitioning in complex urban landscapes with isotope‐aided ecohydrological modelling

چکیده
Urban green space is increasingly viewed as essential infrastructure to build resilience climate change by retaining water in the city landscape and balancing ecohydrological partitioning into evapotranspiration for cooling groundwater recharge. Quantifying how different vegetation types affect future management, but paucity of data complex heterogeneity urban areas make balance estimates challenging. Here, we provide a preliminary assessment from sized patches trees grass well sealed surfaces. To do this, used limited field observations together with an advanced, process-based tracer-aided model at meso-scale (5 km2) central Berlin, Germany. Transpiration was dominant flux accounting over 50% modelled area. Green fluxes were general greater compared grass, large parks transpired more small that intensively recreation. Interception evaporation larger soil trees. We also show tree-covered comprise almost 80% total whole domain while making up less than 30% surface cover. The results form important stepping-stone towards further upscaling highlights importance continuous high-resolution hydrological measurements landscape, need improvements models capture processes.

Modelling functional connectivity pathways for bats in urban landscapes
With the extent and density of urbanised land-use set to increase, implications arise for the quality of semi-natural and ecological processes. This paper incorporates empirical evidence from a study of gap crossing within a least-cost path methodology to develop a model of functional habitat connectivity for P. pipistrellus within the City of Birmingham. The model takes into particular conside...
متن کاملModelling the urban water cycle
Current urban water management practices aim to remove stormwater and wastewater efficiently from urban areas. An alternative approach is to consider stormwater and wastewater as a potential resource substitute for a portion of the water imported via the reticulated supply system. A holistic view of urban water resources provides the framework for the evaluation of the demand for water supply, ...
متن کاملLand use, water and Mediterranean landscapes: modelling long-term dynamics of complex socio-ecological systems.
The evolution of Mediterranean landscapes during the Holocene has been increasingly governed by the complex interactions of water and human land use. Different land-use practices change the amount of water flowing across the surface and infiltrating the soil, and change water's ability to move surface sediments. Conversely, water amplifies the impacts of human land use and extends the ecologica...
