• Legacy Vegetation and Drainage Features Influence Sediment Dynamics and Tidal Wetland Recovery After Managed Dyke Realignment (2025) · Land · cited 7× · doi

  The paper identifies a gap in understanding the effects of legacy vegetation and drainage features on sediment dynamics and tidal wetland recovery. It notes that prior studies have focused on the restoration of tidal flow, but have not considered the impact of legacy features. The study aims to address this gap by examining the effects of these features on the restoration trajectory at a Bay of Fundy site.

• Legacy Vegetation and Drainage Features Influence Sediment Dynamics and Tidal Wetland Recovery After Managed Dyke Realignment (2025) · Land · cited 7× · doi

  The study identifies the challenge of understanding the complex interaction of sedimentary, hydrodynamic, and vegetation processes in tidal wetland landscapes. It notes the difficulty of measuring and modeling the effects of legacy vegetation and drainage features on sediment dynamics and tidal wetland recovery. The research highlights the challenge of balancing the need for accurate measurements with the need for efficient and cost-effective data collection methods.

• Dynamics of water table depths in forested wetlands under temperate climate conditions using multi-frequential periodogram analysis and wavelet analysis (2026) · Frontiers in Environmental Science · doi

  The paper identifies a gap in the current representation of wetland hydrology in hydrological models. It suggests that the current models could be refined to better simulate wetland-specific hydrological processes. The study highlights the need to distinguish between isolated and riparian wetlands in the modelling structure of hydrological models.

• Spatial Analysis of Shoreline Erosion, Delaware Bay, New Jersey (1986) · Annals of the Association of American Geographers · cited 60× · doi

  While the occur- rence and evolution of coastal wetlands is rela- tively well understood, the processes causing spatial variation within the marsh landscape are not well understood. These results point to a need for further study of geomorphological, ecological, and pedologi- cal processes in tidal marshes.
