“…This indicates that these wetlands had become increasingly surface water driven as opposed to groundwater driven as they would naturally occur. Similar effects of LULC on stream hydrology have been repeatedly demonstrated elsewhere (Blann et al, 2009;Hardison et al, 2009;Nagy et al, 2011). Many studies have also found changes in base and peak flow levels because of changing land use (Paul and Meyer, 2001); however, our results did not detect a correlation between watershed run-off (CN and Q) and water table height.…”

“…Urbanization also modifies landscape drainage by increasing impervious surface area that has been shown to increase run-off, reduce water quality and alter stream morphology (Paul and Meyer, 2001;Boggs and Sun, 2011). A general understanding of the effects of land use and land cover (LULC) on streams has emerged (Walsh et al, 2005;Blann et al, 2009;Nagy et al, 2011); however, less is known about upstream headwater wetlands. Headwater wetlands are a critical zone in the drainage network representing the interface between terrestrial and aquatic environments.…”

“…Finally, failure to detect water level differences could be partially attributed to drought conditions during the summer of 2011. Even though water tables returned, groundwater depths during the summer of 2011 were probably lower than normal levels as these wetlands commonly maintain water tables at or near the ground surface (Mitsch and Gosselink, 2000;Noble et al, 2007). The drought limited data collection to only wetter periods of the year and perhaps reduced our capability to detect more typical relationships between wetland water levels and run-off patterns.…”

The effects of land use and land cover (LULC) on aquatic systems have been extensively studied however less research has focused on headwater wetlands. This study was conducted to evaluate the effects of watershed land conversion and associated run-off on the hydrology and carbon cycling of headwater wetlands in coastal Alabama, USA. A total of 15 headwater wetlands were selected to reflect a range of surrounding LULC across coastal Alabama. Land use and soil data were utilized to estimate watershed run-off curve numbers (CN) that were used with precipitation data to calculate surface run-off (Q). Within each wetland, water level recorders were installed to monitor ground water levels for 1 year and data were used to generate hydrological metrics related to stage and flashiness. Data varied among sites, but wetlands with higher watershed CN tended to have a greater tendency for water level measurements to exceed the normal fluctuation range (outliers). Carbon dynamics associated with leaf litter and soil storage were also measured during this time period. Leaf litter traps were installed to determine litter fall carbon input (C LF ). Bimonthly monitoring of forest floor carbon (C FF ) was conducted to evaluate its relationship to watershed run-off. Soil carbon content was quantified in each wetland by collecting 40-cm cores analysed at 10 cm sections. Watershed run-off characteristics (CN and Q) were significantly related to mean C FF and C FF : C LF (C FF adjusted for the amount of C LF ) suggesting that hydrologic export and possibly decomposition increased with run-off. Surface soil (0-10 cm) carbon content was related to median groundwater level; however, no relationship was detected between soil carbon and CN or Q.

“…Wetland vegetation in major creeks and marshes includes Nyssa sylvatica biflora (swamp tupelo), Taxodium distichum (bald cypress), and Sabal palmetto (cabbage palm; Anderson & Lockaby, ).

Mechanisms of Organic Matter Export in Estuaries with Contrasting Carbon Sources

et al. 2019

Modifications in land use and climate will result in shifts in the magnitude and composition of organic matter (OM) transported from wetlands to coastal waters, but differentiation between riverine and wetland OM sources in coastal areas remains a challenge. Here, we evaluate particulate and dissolved OM export dynamics in two representative estuary geomorphologies—Apalachicola Bay (AP) and Barataria Bay (BB), characterized primarily by blackwater river inputs and high particle abundance, respectively. The magnitude and composition of OM exported from each estuary was evaluated based on seasonal measurements of surface water dissolved organic carbon (DOC), particulate organic carbon (POC), particulate nitrogen, the stable isotopic composition of DOC and POC, dissolved and particulate lignin phenols, and carbon‐normalized dissolved lignin‐phenol yields. Data and discriminant analyses support the initial hypothesis; AP is dominated by a more terrestrial source of OM due to importance of fluvial dissolved OM inputs, while BB is a more particle‐rich and wetland carbon‐dominated system. Total lignin export (sum of mean dissolved and mean particulate) was higher in BB (5.73 ± 2.50 × 105 kg/year) than in AP (4.21 ± 2.35 × 105 kg/year). Particulate lignin export from BB was greater than the export of dissolved lignin at either BB or AP, suggesting coastal marsh erosion may be driving this comparatively large export of particulate lignin. These data have important implications for the stability of stored OM in coastal habitats, particularly since such habitats in this region are highly vulnerable due to relative sea level rise.

“…The development of urban environments leads to an increase of nutrients concentration and fecal coliforms due to the discharge of domestic effluents [4]. This contamination promotes modifications in the physical-chemical characteristics of the water, and in turn, the quality of the aquatic environment [5]. The addition of nutrients promotes ecosystem-level problems, such as algal blooms, biochemical oxygen demand increase and hypoxia [6].…”

BackgroundThe use of interdisciplinary approaches such as the proposed report provides a broad understanding of the relationship between people and the environment, revealing reliable aspects not previously considered in the study of this relationship. This study compiled evidence on the environmental degradation of an urbanized river over the past few decades, providing a diagnosis of the consequences of this process for the river, its ichthyofauna, and the local human population.MethodsThe study was focused on the Beira Rio community on the Capibaribe River in the municipality of São Lourenço da Mata, Pernambuco, Brazil. Data were collected using geoprocessing and ethnobiological approaches, as well as environmental parameters. This research was conducted with the most experienced long-term residents in the local community, through interviews and participatory methodologies to recovering information about the river environment, its ichthyofauna and its environmental services for the last decades.ResultsAccording to the GIS analysis, the study area was subject to an accelerated process of urbanization, with the total urban area increasing from 73 565, 98 m2 in 1974 to 383 363, 6 m2 in 2005. The informants perceived the urban growth, especially in the late twentieth century, being this period recognized as the phase of greatest negative changes in the river environment. The perceived decline of fish stocks was indicated by the community as one of the effects of river degradation. According to the interviews, the deterioration of the river affected the ecosystem services and the relationship of the adjacent human community with this ecosystem. The environmental data indicated that the river is suffering eutrophization and has fecal coliform concentrations 160 times higher than the maximum level permitted by Brazilian legislation.ConclusionsThe interdisciplinary approach used in this research allowed the understanding of the degradation process of an urban river and some negative effects through the integration of environmental data, GIS and the local knowledge, revealing the complementarity of obtained data and the effectiveness of implementation of this approach.
