A thin layer of cohesive soil and sandy clay covers the wetland surface.
The accumulated depositions on the seabed and wetland surface were calculated.
The concept, watershed governance, can promote connections among forest, land, wetland, surface and ground waters, and vegetation based on the spatial and temporal scales of basin management.
A model of coastal wetlands is analyzed, based on interactions among relative sea level, wetland surface elevation, hydroperiod, vegetation, and sedimentation.
SfM photogrammetry enables mapping of important hydrological features, such as creeks carrying drainage from upland watersheds or connectivity of ponds on the wetland surface.
However, little is known about the effects of sediment diversions on existing wetland surface elevation and vertical accretion dynamics in the receiving basin at the landscape scale.
According to the landform of the valley, groundwater should flow out as springs at the slope foot adjacent to the wetland, or seep directly at the wetland surface, indicating that the wetland was maintained by groundwater or spring.
Rates of CO2 production ranged from − 76 to 388 nmol kg− 1 s− 1 under anoxic conditions and from 0.1 to 402 nmol kg− 1 s− 1 under oxic conditions, with the highest rates in natural wetland surface soils.
Among all treatments, the dry-weather harvested sites without bedding presented the fastest recovery of water table depth to that of the non-harvested references, suggesting that bedding may have been a further disturbance with respect to wetland surface hydrology.
In this study, we used a spatial wetland surface elevation model developed in support of Louisiana's 2012 Coastal Master Plan to examine such landscape-scale effects of sediment diversions.
