Abstract

ABSTRACT Srinagar city experienced significant expansion especially during the last four decades, which has negatively impacted its aquatic resources and their functioning. The present study aims to assess the impact of the urban growth on the natural drainage network of the Srinagar city from 1971 to 2020. The changes in the morphometry of natural drainage and urban morphology were quantified through the selected indicators. Four sample sites were selected from the study area for detailed ground validation of the quantified changes. Our results reveal that there has been almost a fourfold increase in the built-up area, taking place in all the directions, primarily in the form of edge expansion that has largely encroahed the urban streams. The findings further indicate that on the whole drainage system of the city has lost almost 15% of its total capacity. The effects of increasing built-up warrant immediate attention to initiate conservation measures for the natural drainage network of the city.

城市发展对斯利那加市自然排水网络的影响

摘要斯利那加市经历了显著的扩张，尤其是在过去的四十年里，这对其水资源及其功能产生了负面影响。本研究旨在评估1971年至2020年斯利那加市城市增长对自然排水网络的影响。通过选定的指标量化了自然排水和城市形态形态计量学的变化。从研究区域中选择了四个样本点，对量化变化进行详细的地面验证。我们的研究结果表明，建成区的面积在各个方向上几乎增加了四倍，主要是以边缘扩张的形式，这在很大程度上包围了城市溪流。调查结果进一步表明，整个城市的排水系统已经失去了其总容量的近15%。增加建成区的影响值得立即关注，以启动城市自然排水网络的保护措施。

期刊介绍： Urban Water Journal provides a forum for the research and professional communities dealing with water systems in the urban environment, directly contributing to the furtherance of sustainable development. Particular emphasis is placed on the analysis of interrelationships and interactions between the individual water systems, urban water bodies and the wider environment. The Journal encourages the adoption of an integrated approach, and system''s thinking to solve the numerous problems associated with sustainable urban water management. Urban Water Journal focuses on the water-related infrastructure in the city: namely potable water supply, treatment and distribution; wastewater collection, treatment and management, and environmental return; storm drainage and urban flood management. Specific topics of interest include: network design, optimisation, management, operation and rehabilitation; novel treatment processes for water and wastewater, resource recovery, treatment plant design and optimisation as well as treatment plants as part of the integrated urban water system; demand management and water efficiency, water recycling and source control; stormwater management, urban flood risk quantification and management; monitoring, utilisation and management of urban water bodies including groundwater; water-sensitive planning and design (including analysis of interactions of the urban water cycle with city planning and green infrastructure); resilience of the urban water system, long term scenarios to manage uncertainty, system stress testing; data needs, smart metering and sensors, advanced data analytics for knowledge discovery, quantification and management of uncertainty, smart technologies for urban water systems; decision-support and informatic tools;...
