Abstract
ABSTRACT Urban wetlands and waterways are vital for a city’s defence, transport, water supply, environment, and culture. However, overuse, environmental stress, and management issues degenerate their condition, particularly in countries with high populations, limited funds, and improper infrastructure. A megacity in eastern India, Kolkata is blessed with two significant rivers, an efficient canal system, and a wetland of international prominence. Unfortunately, various factors disturbed their natural flow, slaying them with pollution, sedimentation, and reduced aquatic biodiversity, thus losing their socio-cultural importance. The paper analyses the interactions and inter-relationships between the city’s main waterways in a comprehensive environmental, socio-economic, and cultural context. It also presents a prescriptive framework for the eco-restoration and management of the city’s waterways. The target-driven strategies comprise the spatio-physical components of land, land-water interface, and water for physical, ecological, and hydro-morphological restoration of these waterways as an urgent step towards urban sustainability and resilience.
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;...
