Creeks are the inherent coastline feature that connects rivers to the sea and plays an important role in the ecological processes and the material transfer. In the present study, an impact of urbanisation on the creeks of Mumbai, India namely Thane, Malad and Manori creeks, has been addressed. Multi-temporal satellite images of Landsat for the years 1972, 1994 and 2016 are considered to perform the changes in the mudflat and growth of the mangrove, as well as the changes in creeks width apart from the Land use Land cover (LULC). Object-based image analysis using multi-spectral resolution confirmed that there is an overall increase in the spatial extent of mangroves and reduction in the width of all the creeks. Mangroves around Thane creek and Manori creek have increased from 50.7 km² to 57.6 km² and 8.4 km² to 25.2 km²respectively. However, there is a decrease in mangroves around Malad Creek from13.3 km² to 9.7 km²during 1972 to 2016. The relationship between the creek geometry and LULC was also explored, and it has been revealed that the creek width has reduced due to urbanisation. Life expectancy analysis projected a further reduction in the width of the creeks for the years 2025 and 2050. The study suggests that there must be stringent bye-laws for disposal of sewage into the creeks and development activity near the creek areas. Further, upper stretches of the creeks require cleaning and dredging so that the tidal water will be approached up to the upper portion to maintain the creek ecosystem.

城市化对印度孟买小溪的影响：一种地理空间评估方法

溪流是连接河流和海洋的固有海岸线特征，在生态过程和物质转移中起着重要作用。在本研究中，已经解决了城市化对印度孟买小溪（塔那，马拉德和马诺里小溪）的影响。1972年，1994年和2016年的Landsat多时相卫星影像被认为可以实现红树林的滩涂变化和红树林的生长以及除土地利用土地覆盖（LULC）以外的小溪宽度的变化。使用多光谱分辨率的基于对象的图像分析证实，红树林的空间范围总体增加，所有小河的宽度减少。塔那河和马诺里河周围的红树林已从50.7 km ²增加到57.6 km ²和8.4 km ²至25.2 km ²。然而，在围绕Malad溪红树林从13.3公里减小²至9.7公里² 1972期间2016小溪几何形状和LULC之间的关系也进行了探讨，并且已经发现该小溪宽度已经由于减少城市化。预期寿命分析预测，到2025年和2050年，小河的宽度将进一步减少。研究表明，必须有严格的细则，将污水排入小河并在小河附近地区进行开发活动。此外，小河的上游部分需要清洁和疏ging，以便将潮汐水引到上部，以维持小河的生态系统。
