There has been a steady decrease in the area occupied by wetlands in creeks and estuaries adjacent urban areas due to unprecedented urban growth in coastal cities, for example, Thane Creek and Ulhas River Estuary near Mumbai, India. Urban cities serve as centres of employment and attract a large number of migrants from other places. In case of coastal cities, due to inadequate infrastructure, wastewater and solid waste are disposed of into wetlands and estuary. Discharge of sediments and solid waste into the creeks from drains and construction activities has resulted in decreased flow depth in the coastal waters of Thane Creek and Ulhas River Estuary. Various researchers have studied individual elements of Thane Creek and Ulhas River Estuary at micro level. However, a holistic approach for restoration and conservation of the creek and estuary is required. This paper presents the details of an integrated approach incorporating different conservation measures such as sewerage and sewage treatment, urban drainage management, solid waste management, mangrove plantation and dredging.
由于沿海城市前所未有的城市扩张，如印度孟买附近的塔那河和乌尔哈斯河河口，城市周边小溪和河口的湿地面积一直在稳步减少。城市是就业中心，吸引了大量来自其他地方的移民。对于沿海城市来说，由于基础设施不足，废水和固体废物被排放到湿地和河口。排水和建筑活动将沉积物和固体废物排放到小溪中，导致塔那河和乌尔哈斯河河口沿海水域的水流深度降低。许多研究人员在微观层面研究了塔那河和乌尔哈斯河河口的各个要素。然而，需要一种整体方法来恢复和保护这条小溪和河口。本文详细介绍了一种综合方法，该方法纳入了不同的保护措施，如下水道和污水处理、城市排水管理、固体废物管理、红树林种植和疏浚。
