<sec><title>Objective</title> River ecosystems are increasingly threatened by habitat degradation and heightened flood risks due to rapid urbanization and the intensification of extreme climate events. Restoring river floodplains, as a nature-based solution (NBS), offers a promising approach to address these challenges by providing multiple benefits, including flood control, ecological restoration, and recreational opportunities. However, identifying floodplains with high restoration suitability remains a critical scientific challenge in basin management. This research aims to develop a comprehensive framework for evaluating the suitability of river floodplains restoration, with the goal of maximizing social and ecological benefits at the basin scale. By focusing on the integration of hydrological, ecological, and socio-economic factors, this research seeks to provide a scientifically robust method for prioritizing floodplain restoration efforts. </sec><sec><title>Methods</title> This research proposes a multi-dimensional floodplain restoration suitability evaluation framework, integrating Geographic Information Systems (GIS) and the HEC-RAS (Hydrologic Engineering Center’s River Analysis System) hydrodynamic model. The framework incorporates multi-source data, including digital elevation models (DEM), land use classifications, vegetation indices (NDVI), soil types, and socio-economic factors, to evaluate the restoration potential of floodplains. This research uses a multi-level hierarchical screening method to select indicators at three scales: basin, sub-basin and site. Through multi-scale and multi-dimensional synergistic evaluation, the research avoids not being able to conduct global analysis due to insufficient data, and also prevents ignoring the overall restoration effect by limiting to the local area. Key indicators such as hydrological conditions, ecological habitats, water quality, vegetation cover, and socio-economic factors are identified and quantified. The entropy weight method is employed to calculate the restoration suitability index, ensuring an objective weighting of each indicator. Finally, region-specific socio-economic factors are incorporated into the evaluation system for the final selection of restorable floodplains. Hydrodynamic simulations are conducted using HEC-RAS to model baseline and post-restoration scenarios. These simulations help evaluate changes in flood behavior and habitat conditions under various flow events. A case study is conducted in the middle and lower reaches of the Liuxi River Basin in Guangzhou, China, to validate the framework. The research area is selected due to its susceptibility to frequent flooding, rich biodiversity, and strategic importance in regional greenway planning. </sec><sec><title>Results</title> The results indicate that the middle and lower reaches of the Liuxi River Basin exhibit high floodplain restoration suitability.

<sec> <title>Objective</title> Located in Qingzhou City, Shandong Province, Ouyuan Garden is a private urban garden constructed by Grand Secretary Feng Pu (1609−1692) during the reign of Emperor Kangxi in Qing Dynasty (1669−1670). The well-preserved southern section offers a valuable case for studying traditional Chinese gardens and designed landscapes. However, significant gaps still need to be bridged in understanding the cultural significance and heritage value of the garden. The recent application of digital mapping technologies provides new opportunities for precise analysis. In this context, this research aims to interpret the garden’s landscape features, analyze its design techniques, reevaluate its heritage value, and reflect on the use of digital surveying in garden heritage research. </sec> <sec> <title>Methods</title> First, to comprehensively understand Ouyuan Garden’s physical characteristics, the research team conducted a 3D digital survey from May to June 2021, and created a complete digital archive using such technologies as 3D laser mapping and close-range photogrammetry. Second, based on the survey data and historical documents, the research employs such methods as mutual corroboration between literature and examples, landscape visual analysis, and text-image analysis to explore the garden’s landscape features and design techniques. Finally, the research assesses the garden’s heritage value and offers reflections on the use of digital surveying technology in garden heritage research. </sec> <sec> <title>Results</title> Ancient Chinese gardens are defined by five key elements: General layout, rockery, building, plant, and waterscape. Specifically, the layout shapes the spatial form and atmosphere of gardens, while the other four elements form the scenic composition. In view of the complex rockery in Ouyuan Garden, a separate research titled <italic>Artistic Mastery and Celestial Landscapes: An In-depth Examination of the Artificial Mountain in Ouyuan Garden</italic> is conducted for a detailed analysis of the garden’s rockery. As part of the broader research on Ouyuan Garden, this research aims to develop a comprehensive research framework with a focus on the remaining four elements. 1) General layout: Ouyuan Garden centers around the main hall, Jiashan Hall (“Jiashantang”), and a rockery along the wall, forming a cohesive spatial framework. Jiashan Hall, the main peak of the aforesaid rockery, and the courtyard stone align along the north-south axis, establishing the garden’s main structure. Surrounding vegetation, pavilions, ponds, and streams create a lush mountain setting. The rockery, stream, and paths are strategically arranged to offer expansive horizontal views, while tall pines and dense foliage enhance the vertical landscape. This design allows visitors to ommersively experience the garden’s depth and complexity from various perspectives. 2) Buildings: The southern section of Ouyuan Garden originally featured seven buil

This paper explores the typologies and characteristics of classical Vietnamese gardens built in the Nguyen Dynasty (1802–1945) by examining historical records, paintings, and existing gardens. The findings highlight the presence of two distinct types of classical gardens in Vietnam: imperial gardens and imperial mausoleum gardens. Numerous examples from Chinese gardens constructed during the Ming and Qing Dynasties are employed for comparison with Vietnamese gardens. Influenced by Chinese culture, Vietnamese gardens exhibit numerous shared characteristics and elements with their Chinese counterparts. Layouts, architectural styles of pavilions, garden elements such as rockeries, ponds, and bridges, as well as plant materials were inspired by Chinese gardens, yet they were adapted to align with local conditions, such as climate and garden owners' preferences. For example, the arrangement and design of some elements, like waterscapes and bridges, species of plants and stone materials were different. Understanding the cultural significance and uniqueness of Vietnamese classical gardens contributes to their preservation and restoration. By recognizing and comparing the philosophical approaches to garden design in China and Vietnam, this research sheds light on the diverse expressions and adaptations of garden design in East Asia. ● Classical Vietnamese gardens were influenced by Chinese culture and philosophies ● Classical Vietnamese garden’s layouts, architecture, rockeries, and plants are the aspects showing the influences of Chinese culture, but have distinctive characteristics that set them apart ● Gaining insights into classical Vietnamese gardens could contribute to the development of modern landscape design in Vietnam

Located in Wilmington, Delaware, along the shoreline of the Brandywine Creek in the Greater Philadelphia/Delaware River Watershed, this project responds to a specific and critical need for the site as prioritized by multiple stakeholders. The project applies an innovative approach for quantifying increased flood resilience while simultaneously reducing contamination levels through the implementation of green infrastructure. To solve joint issues related to increased flood risk concurrent with higher potential for exposure to environmental contaminants transported in flood waters from adjacent industrial sites, brownfields, and combined sewer overflows, the research team develops a phased approach to decreasing stormwater runoff and pollutant loads on a 130-acre (52.6 hm2) site along the Brandywine Creek, applying the Long-Term Hydrologic Impact Assessment (L-THIA) model to quantify design impacts and performance of a master plan. Overall, the proposed master plan can reduce stormwater runoff and pollutant loads to levels significantly less than existing conditions or the current land use plan. Further, this research is unique in that it uses outputs from the L-THIA to compare existing conditions, effects of the current comprehensive plan, and impacts related to the proposed neighborhood-scaled master plan to evaluate the effectiveness between each scenario.

Many urban areas affected by flood disasters are also becoming increasingly ecologically and socially fragmented due to the accumulation of vacant properties. While redevelopment is often viewed as the primary objective in regenerating vacant properties, they can also potentially provide ecological and hydrological land uses. Rather than chasing development- based incentives for regenerating vacant lots in high flood-risk communities, a balance should be sought between new developmental land uses and green infrastructure to help counteract stormwater runoff and flood effects, or "Resilience through Regeneration." This paper uses landscape performance measures to evaluate the economic and hydrologic performance of green infrastructure regeneration projects for three marginalized neighborhoods in Houston, Texas, USA. Each project site is characterized by excessive vacant lots and flood issues. Results suggest that, when using green infrastructure to regenerate vacant properties, 1) flood risk continually decreases, 2) upfront economic costs increase in the short term (when compared to conventional development), and 3) the long-term economic return on investment is much higher.
