“…Since 2014, in response to the urgent issues containing urban flooding, environmental protection and ecological restoration in China (Wang et al, 2004;Xia et al, 2017), "Sponge City" (H. , the innovative urban development mode described from the perspective of integrating storm management and urban planning (He et al, 2019) has been proposed and employed. Implementing wider applications of LIDs, reducing runoff by effectively using LIDs and decreasing the impacts of storms and urbanization on the nature have become the primary goals of "Sponge City" construction (Ding et al, 2019). LID and LIDs begin to enter the fields of the wider application and researches in China.…”

In this paper, based on remote sensing image processing and SWMM simulation, we evaluate the effectiveness of a coupled LIDs system for the watershed scale. The main content and contributions include: 1) the extraction and classification of historical and recent LULC data (in 1979, 1989, 1999, 2009, 2017) of the study area and an analysis of the characteristics of the LULC change; 2) a watershed-based SWMM applied to the simulation of the runoff and an analysis of the runoff change characteristics; 3) the proposal and design of three coupled LIDs scenarios which treat runoff change as evaluation metric to systematically discuss the effectiveness of LIDs in the watershed. The results show that the combination structure and scale can significantly affect the coupled LIDs effectiveness. A system with multiple LIDs is more effective than one with only single LIDs. With the increase of spatial scale, the effectiveness of the coupled LIDs gradually weakens. Our research enriches the application scale of LIDs and SWMM, and can be beneficial to the construction of the "Sponge City", storm management and urban planning.

“…With the development of urbanization and expansion of urban agglomeration, artificial impermeable pavement has occupied the urban surface at a large scale, blocking the natural infiltration process of rainwater [1]. The resulting "urban diseases", such as urban floods, water resources shortage, and urban heat islands (UHIs), threaten sustainable urban development [2,3]. Porous asphalt mixture (PAM), as a sustainable pavement material for cities, has been developed and applied to parking lots and light traffic pavement due to its potential for alleviating "urban syndrome".…”

Laboratory Evaluation on the Performance of Porous Asphalt Mixture with Steel Slag for Seasonal Frozen Regions

et al. 2019

Porous asphalt mixtures with steel slag (PAM-SS), as an eco-friendly and low-cost pavement material, are conducive to addressing the issue of urban floods and natural resource shortages. The primary objective of this paper was to explore the feasibility of the application of PAM-SS for seasonal frozen regions, and ascertain the optimal replacement percentage of natural aggregate. Steel slag coarse aggregate (SSCA) was used to replace basalt coarse aggregate (BCA) at four levels (25%, 50%, 75%, 100%) by equal volume. The volume characteristics, mechanical properties, low-temperature cracking resistance, water stability, and freeze-thaw (F-T) durability of the mixture were assessed. The results indicated that the low-temperature cracking resistance of the mixture was significantly enhanced and acoustic emission (AE) energy was uniformly released by the incorporation of steel slag. Furthermore, the porosity, permeability, Marshall stability (MS), and the resistance against water damage and F-T cycles were also significantly improved. Based on the experimental results, the complete replacement of natural aggregate is advisable to obtain an optimal overall performance.

“…Hence the non-standardised nature of the expert evaluation and random survey evaluation methods may provide an opportunity for a provincial government to manipulate evaluation results for its own benefit. Moreover, although public participation and satisfaction are taken as evaluation criteria, usually the citizens living in proximity to the project do not actually know about the Sponge city project [24]. Are there advertisement campaigns?…”

This study carries out an in-depth analysis of urban water policy implementation in China through a policy cycle analysis and case study of Sponge city program. The policy cycle analysis articulates discrete steps within the policy formulation and implementation process, while the case studies reflect the specific problems in water project implementation. Because of the principal–agent relation between central and local government, a ‘‘double wheel’’ policy cycle model is adopted to reflect the policy cycles at central level and at local level. Changde city and Zhuanghe city, two demo cities in the Sponge city program, are chosen for the analysis. The policy cycle analysis shows that the central government orders local government to implement policy without clear direction on how to attract private sector participation. The evaluation of central government did not include private sector involvement, nor the sustainability of the investments. This promotes the local government’s pursuit of project construction completion objectives, without seriously considering private sector involvement and operation and maintenance (O&M) cost. The local governments do not have political motivation and experiences to attract private investments into project implementation. The case study in the two demo cities shows that local government subsidies are the main source of O&M funding currently, which is not sustainable. The water projects are not financially feasible because no sufficient revenue is generated to cover the high initial investments and O&M cost. The lack of private sector involvement makes it difficult to maintain adequate funding in O&M, leading to the unsustainability of the water projects. It is not easy to achieve private sector involvement, but it could be the key to realizing urban water resilience in a more sustainable way.
