Stream metabolism in urban environments
We are using online water quality measurements to improve our understanding how lowland streams are responding to environmental changes. We are working within the framework of StreamPULSE, a community of researchers building the scientific capacity to answer questions on stream metabolism with modern sensor technology and novel modeling infrastructure.

Impact of losing vs. gaining stream flow conditions on hyporheic exchange in heterogeneous sediments
The objectives of this study are 1) evaluate the effect of overlying velocity and streambed heterogeneity on temperature and oxygen gradients in the hyporheic zone, 2) evaluate the effects of subsurface flow patterns resulting from neutral, losing, or gaining stream flow conditions on temperature and oxygen gradients in the hyporheic zone, and 3) develop and validate a coupled hydrodynamic-heat transfer-biochemical modeling suite for the prediction of factors influencing hyporheic exchange and oxygen consumption in the streambed.

Stream Biogeochemstry
Stream water quality is affected by a complex interplay between biogeochemical reactions in the benthic sediments as well as downstream transport. Nutrient uptake and macroinvertebrate community structure in a highly regulated Mediterranean stream receiving treated wastewater Here we study how the improvement in the treated wastewater quality from the secondary to the tertiary level influenced N uptake, P uptake, and macroinvertebrate assemblage in the Yarqon Stream (Israel).
