Reconnaissance Investigation of Sedimentation Patterns in a Small Modern Anthropogenically Influenced Inlet, Otūwhero Estuary, Abel Tasman National Park, New Zealand

open access: yesNew Zealand Journal of Marine and Freshwater Research, Volume 60, Issue 3, September 2026.
The structurally controlled Otūwhero estuary on the SE boundary of Abel Tasman National Park is a small partially filled incised valley. The small size, limited number of fluvial inputs, accessibility and surrounding land use made it an ideal candidate on which to investigate potential climate‐induced estuarine behaviour. Surficial sediment samples and

A review of preferential flow and transport through root channels

open access: yesVadose Zone Journal, Volume 25, Issue 5, September/October 2026.
Abstract Preferential flow can contribute up to 80%–90% of the flow and transport in the vadose zone. The root channels are the most prevalent form of preferential pathways. They create an evolving network of preferential pathways and are biogeochemical hotspots due to preferential transport of nutrients and other organics, colonization of bacteria ...
