The river corridor is a diverse zone in terms of its scale, situation and character, and is often heavily modified by human activity. Its natural function is to mediate the transport of water and dissolved and particulate material to the river network. The sedimentological and biogeochemical functions are particularly important to the long-term restoration/conservation of the river habitat. However, the biogeochemical processes and transportation involved are affected by complex interactions between the surface, hyporheic and groundwater flow in this environment.

This edited volume addresses research issues focused on the biogeochemistry of the riverbank with special reference to data observation, modelling and attempts to restore these environments. The contents are subdivided into the following themes:

Organic carbon in upland wetlands and in flood plain rivers

Nutrients in the river corridor and wetland environment, with an
emphasis on understanding nitrogen and phosphorus dynamics

River corridor zonation attributes, such as seasonal water table
fluctuation and vegetation dynamics

River corridors and ecosystem health
