Rivers are important ecosystems under continuous anthropogenic stresses. The hyporheic zone is a ubiquitous, reactive interface between the main channel and its surrounding sediments along the river network. We elaborate on the main physical, biological, and biogeochemical drivers and processes within the hyporheic zone that have been studied by multiple scientific disciplines for almost half a...

Water and heat transport of paved surfaces

Timm, Anne (2019)

The urban soil-atmosphere is typically paved with varying materials. This alteration has drastic effects on the urban hydrological balance. With a focus on stormwater management, most existing models treat all types of pavements identically when estimating runoff and neglect losses caused by evaporation and infiltration processes. A literature review reveals that very few studies have been publ...

Adapting the water management to mitigate the impact of multiple stressors on an urban lake

Ladwig, Robert (2019)

Urban lakes are aquatic ecosystems that are influenced by a water management system and by a possibly strongly sealed urban catchment. The water management aims to fulfill multiple objectives: providing drinking water, sanitation and recreation for the people as well as keeping the ecosystem in a sustainable and resilient state. Urban lakes are facing several stressors. For instance, climate ch...

Evaluating the Impact of Wastewater Effluent on Microbial Communities in the Panke, an Urban River

Nega, Marcella ; Braun, Burga ; Künzel, Sven ; Szewzyk, Ulrich (2019-04-28)

Pharmaceuticals are consumed in high amounts and can enter as emerging organic compounds in surface waters as they are only partially retained in wastewater treatment plants (WWTPs). Receiving pharmaceuticals may burden the aquatic environment, as they are designed to be bioactive even at low concentrations. Sediment biofilm populations were analyzed in river sediments due to the exposure of an...

Estimating Pore Water Electrical Conductivity of Sandy Soil from Time Domain Reflectometry Records Using a Time-Varying Dynamic Linear Model

Aljoumani, Basem ; Sanchez-Espigares, Jose A. ; Wessolek, Gerd (2018-12-13)

Despite the importance of computing soil pore water electrical conductivity (σp) from soil bulk electrical conductivity (σb) in ecological and hydrological applications, a good method of doing so remains elusive. The Hilhorst concept offers a theoretical model describing a linear relationship between σb, and relative dielectric permittivity (εb) in moist soil. The reciprocal of pore water elect...
