Atmospheric concentrations of the powerful greenhouse gas nitrous oxide (N 2 O) have
increased dramatically over the last 100 years, and part of these emissions come from …

Fifty years of hyporheic zone research have shown the important role played by the
hyporheic zone as an interface between groundwater and surface waters. However, it is only …

The main purpose of this chapter is to give a derivation, which is mathematically precise,
physically natural, and conceptually simple, of the quasilinear system of partial differential …

Stream denitrification is thought to be enhanced by hyporheic transport but there is little
direct evidence from the field. To investigate at a field site, we injected 15NO3−, Br …

This book presents an account of theories of? ow in porous media which have proved
tractable to analysis and computation. In particular, the t-ories of Darcy, Brinkman, and …

The interface between groundwater and surface water within riverine/riparian ecosystems—
the hyporheic zone (HZ)—is experiencing a rapid growth of research interest from a range of …

In this chapter, the authors provide a comprehensive analysis and synthesis of the
interactions between important drivers and controls of hyporheic exchange and …

Hyporheic exchange is the mixing of surface and shallow subsurface water through porous
sediment surrounding a river and is driven by spatial and temporal variations in channel …

The hyporheic zone is an ecotone connecting the stream and groundwater ecosystem that
plays a significant role for stream biogeochemistry. Water exchange across the stream …

A model for the evaluation of the intra‐meander hyporheic exchange fluxes is presented.
The method relies on a physically‐based morphodynamic model to predict the …
