Simulation and Analysis of Water Quality Improvement Measures for Plain River Networks Based on Infoworks ICM Model: Case Study of Baoying County, China

Water, Journal Year: 2024, Volume and Issue: 16(18), P. 2698 - 2698

Published: Sept. 23, 2024

The water environment of plain river networks can be self-cleaning to a certain extent, but if the wastewater load exceeds threshold, it disturb natural balance and cause pollution. This underlines importance pollution control measures. However, development measures requires large number hydrological hydrodynamic parameters establishment corresponding relationships through modelling. Therefore, this study mainly used Infoworks ICM model construct detailed hydrological–hydrodynamic analysis for Yundong area Baoying County, Yangzhou City, China, screened main source areas time periods typical rivers in area, proposed effective improvement according actual situation area. results show that after synergistic effect multiple measures, quality reach Class III standard (GB3838-2002). provide reference management network has good application prospects.

Public Perception of Innovative Technical Solutions for the Development of the ‘Sponge City’ Concept in Poland: A Case Study of the Tri-City Area

Sustainability, Journal Year: 2025, Volume and Issue: 17(6), P. 2380 - 2380

Published: March 8, 2025

Water resources in the European Union are diverse. For example, Croatia has almost 18 times water that Poland has. Although key factor causing shortages is population growth, this crisis primarily determined by dynamic development manifested country’s urbanization and industrialization. These changes particularly troublesome urban areas. Therefore, sound remedial adaptive actions related to of “sponge city” concept necessary. The implementation contributes a reduction rainwater losses heat-island effect. success largely opinions city residents towards it, which makes results research important. This article presents respondents about innovative technical solutions surrounding city”. was conducted means survey method. statements were formulated based on critical analysis literature. carried out one Polish agglomerations, using CAWI technique. achieved discussed after their detailed statistical analysis. respondents’ impact implementing for not strongly differentiated. level knowledge relatively low. it important undertake activities aimed at both education problem marketing promoting its importance environment quality life.

An Evaluation of Sponge City Construction and a Zoning Construction Strategy from the Perspective of New Quality Productive Forces: A Case Study of Suzhou, China

Land, Journal Year: 2025, Volume and Issue: 14(4), P. 836 - 836

Published: April 11, 2025

With the acceleration in urbanization, surface hardening has increased, urban flooding and soil erosion problems are frequent, water resource management faces great challenges. Sponge city construction can effectively alleviate these by simulating natural cycle constructing blue–green infrastructure. In this study, analytic hierarchy process (AHP) ArcGIS weighted overlay tool were used to construct a framework for assessing suitability of sponge Suzhou from three dimensions Geo-Smart spatial productive forces, Eco-Dynamic green Resilio-Tech responsive forces. A zoning strategy based on new quality forces is also proposed. The results show that be divided into types zones according level: key zones, secondary general zones. account about 28.01% total land area, mainly covering built-up areas Suzhou, developed such as Gusu District, Xiangcheng, Industrial Park, other Northern Kunshan. area hand, 61.94% 10.05% respectively. From study proposes following guidelines zones: (1) enhance coordinated development planning construction; (2) promote infrastructure development, strengthen inter-departmental cooperation, ensure ecological economic co-development; (3) encourage public participation governance. This research offers theoretical practical guidance cities perspective

Simulation and Comprehensive Evaluation of the Multidimensional Environmental Benefits of Sponge Cities

Published: June 28, 2023

The implementation of grey and green infrastructure is an effective mean to address urban flooding nonpoint source pollution, but due the complexity process diver-sity benefits, there a lack measurement for their comprehensive benefits. Adopting typ-ical university in Beijing as example, this paper simulated multidimensional benefits water quantity, quality, ecology facility renovation by coupling storm management model (SWMM) InfoWorks Integrated Catchment Manage-ment (ICM). Monetization methods economical means were employed characterize results showed that retrofitting re-duces number severe overflow nodes study area 54.35%, total vol-ume 22.17%, pollution level approximately 80% under heavy rain scenario 60% rainstorm scenario. annual infra-structure reached ¥765,600/year, amount, ¥83,100/year from hydrological regulation, ¥454,100/year reduction, ¥228,300/year ecological improvement. facilities higher than those facilities, combined negatively correlated with rainfall level, bene-fit–cost ratio 1.19. provide methodological data support in-frastructure within context sponge cities.

Study on Suburban Land Use Optimization from the Perspective of Flood Mitigation—A Case Study of Pujiang Country Park in Shanghai

Sustainability, Journal Year: 2024, Volume and Issue: 16(8), P. 3436 - 3436

Published: April 19, 2024

The integration of nature-based solutions into land use optimization has become a central focus current research, primarily due to its effectiveness in mitigating flooding impacts and promoting sustainable development both urban rural areas. Taking Shanghai’s Pujiang Country Park as case study, this paper conducts simulation analysis assess the flood mitigation three distinct patterns (Natural scenario, Scenario N; Complete urbanization U; Planning P) under five stormwater scenarios with return periods 2, 5, 10, 20, 50 years. findings reveal that P exhibits superior performance, particularly period less than Building upon these results, proposes recommendations for optimizing mitigate impact flooding. This study is crucial understanding mechanisms involved logging through methods holds significance decision-making planning at micro level.

Carbon Emission Accounting and Reduction Evaluation in Sponge City Residential Areas

Water, Journal Year: 2024, Volume and Issue: 16(17), P. 2535 - 2535

Published: Sept. 7, 2024

This paper aims to establish a more standardized and regulated carbon emission accounting model for sponge cities by unifying the content emissions clarifying relationships between reduction benefits, effects, sequestration, in order evaluate outcomes mechanisms of city construction. Based on Life Cycle Assessment (LCA) using factor method, newly constructed residential area Tianshui City, Gansu Province, was selected as case study, effect construction then investigated. Results indicated that 30-year full life cycle amounted 828.98 tons, compared 744.28 tons CO2 traditional construction, representing 47.31% emissions. Over cycle, this equated total 1460.31 tons. Additionally, under various rainfall scenarios typical year, exceeded emissions, achieving neutrality within 22 30 years operation. demonstrates communities is significant. The findings study provide data theoretical basis low-carbon China.
