Here we review an extensive series of studies of Barataria Basin, an economically and ecologically important coastal basin of the Mississippi Delta. Human activity has greatly altered the hydrology of the basin by decreasing riverine inflows from leveeing of the river and its distributaries, increasing runoff with high nutrient concentrations from agricultural fields, and channelization of wetlands of the basin interior that has altered flow paths to often bypass wetlands. This has resulted in degraded water quality in the upper basin and wetland loss in the lower basin. Trophic state analysis found the upper basin to be eutrophic and the lower basin to be mesotrophic. Gross aquatic primary production (GAPP) was highest in the upper basin, lowest in the mid basin, and intermediate in the lower basin. Forested wetlands in the upper basin have degraded over the past several decades due to increased periods of flooding, while there has been massive loss of emergent wetlands in the lower basin due to increasing water levels and pervasive alteration of hydrology. Restoration will entail reconnection of waterways with surrounding wetlands in the upper basin, and implementation of river sediment diversions, marsh creation using dredged sediments and barrier island restoration. Findings from this review are discussed in terms of the functioning of deltas globally.

密西西比河三角洲巴拉塔利亚盆地水文学，湿地动力学，水生代谢，水质和营养状况以及营养生物地球化学的50年研究回顾—系统功能，人类影响和恢复途径

在这里，我们回顾了Barataria盆地的广泛研究，Barataria盆地是密西西比三角洲的经济和生态重要沿海盆地。人类活动极大地改变了流域的水文状况，其原因是减少了河流及其分流堤带来的河流流入，增加了来自农田的高养分浓度的径流，流域内部的湿地被沟渠化，从而改变了水流路径，从而经常绕开湿地。这导致上流域的水质下降，下流域的湿地流失。进行营养状态分析后，发现上盆地为富营养化，而下盆地为中营养。水生初级总产值（GAPP）在上流域最高，中流域最低，下流域中等。在过去的几十年中，由于洪水泛滥的时期，上流域的森林湿地退化，而下流域由于水位增加和水文学的普遍变化而大量消失了新兴湿地。恢复将需要使水道与上流域周围的湿地重新连接，并进行河流沉积物分流，使用疏sediment的沉积物形成沼泽和恢复障壁岛。本文就全球三角洲的功能进行了讨论，对本次审查的结果进行了讨论。恢复将需要使水道与上流域周围的湿地重新连接，并进行河流沉积物分流，使用疏sediment的沉积物形成沼泽和恢复障壁岛。本文就全球三角洲的功能进行了讨论，对本次审查的结果进行了讨论。恢复将需要使水道与上流域周围的湿地重新连接，并进行河流沉积物分流，使用疏sediment的沉积物形成沼泽和恢复障壁岛。本文就全球三角洲的功能进行了讨论，对本次审查的结果进行了讨论。
