    Abstract

    Inland floodplain wetlands have intricate multi-channelled networks and unpredictable wet and dry phases related to variable hydrological regimes and geomorphic processes such as sedimentation and erosion. Hydrological reconnection of river channels with outer floodplain and wetland habitats initiates mobilisation and transformation of nutrients, carbon and biota in inland floodplain wetlands. Here, we summarise our findings of the wetland responses to environmental water releases that aim to address the ecological needs for inundation. Despite highly variable hydro-geomorphic characteristics, habitat-dependent patterns and processes are evident in relation to mobilisation and transformation of nutrients, carbon and biota in inland floodplain wetlands. Environmental watering strategies that seek diverse ecological outcomes should include the inundation of multiple hydro-geomorphic habitats as an important driver of structural and functional responses in inland floodplain wetlands.
