Abdullah Addas is a distinguished expert in the field of Landscape Architecture with a career that spans over two decades. He currently holds the position of Professor at the Department of Landscape Architecture, King Abdulaziz University. Prof. Addas earned his PhD in Landscape Architecture from the University of Sheffield in 2015, followed by a Master’s in Landscape studies from the same institution in 2010. His academic journey began with a Bachelor’s degree in Landscape Architecture from King Abdulaziz University in 2006.
Prof. Addas has held a number of influential roles in academia and higher education administration. He has served as the Vice-President for Graduate Studies and Research at Prince Sattam Bin Abdulaziz University and as the Assistant Secretary-General for Higher Education at the Council of University Affairs, where he oversaw policies and strategies aimed at improving the Saudi higher education sector.
In addition to his academic achievements, Prof. Addas is an active Shura Council Member and has been involved in multiple national initiatives related to higher education reform, institutional excellence, and academic performance enhancement. His work focuses on aligning university strategies with national goals, including Vision 2030, and fostering international collaborations in the field of education and research.
Prof. Addas has an extensive portfolio of research, particularly in urban green spaces, public open space planning, climate change, and the urban heat island effect. His research on the optimization of urban green infrastructure and the development of smart cities has gained international recognition. He has published numerous articles in leading journals, including works on the relationship between urban planning and quality of life, as well as studies on environmental sustainability.
Prof. Addas has been a consultant for the World Bank Group in the field of urban development and planning, where he contributed to projects aimed at enhancing urban resilience and sustainable development. His commitment to sustainability and public welfare is evident through his involvement in a variety of professional and academic organizations, including the Saudi Society of Landscape Architecture, the American Society of Landscape Architects, and the British Association of Landscape Industries.
He is a recipient of several prestigious awards, such as the Prince Faisal bin Fahd Award for Sports Research and the Prince Abdulaziz bin Ayyaf Award for Humanizing Cities, recognizing his contributions to both academic research and the practical implementation of sustainable urban planning solutions.
In recognition of his significant contributions to both academia and public service, Prof. Addas continues to play a leading role in shaping the future of Saudi Arabia's educational landscape and advancing the global discourse on sustainable urban development.

Optimizing urban green infrastructure using a highly detailed surface modeling approach

T... more Urban trees and forests show a better ecosystem with many benefits, including pure air quality. The development of urban green infrastructure (UGI) creates a better management system that greatly impacts social values in an urban system. The UGI and construction activities are receiving much attention for their effectiveness in addressing various urban ecological, social and economic issues. Using green infrastructure in stormwater management can reduce the influence on urban sewerage systems and, eventually, on building water resources. The main goal of the research is to optimize the green infrastructure to provide a less-pollution, well-organized, and pleasurable environment for the inhabitants. Various models are used to study the present rainfall-runoff scenario, but the stormwater management model (SWMM) is the most preferable and suggested model. Once the parameters are accessed, optimizing the green infrastructure (GI) will be easy. A complete SWMM model is evaluated over the complete surface, and a hydrological measurement is presented. The evaluation study presents various component percentages: asphalt (37%), green (27%), ceiling (21%), grit (12%), and cemented area (2%), which provides rainproof coverage of approximately 60%. A design is developed about the diverse events of GI in urban exploiting the SWMM and demonstrates its stimulus on the rainfall-runoff behaviour. In recent years, very little attention has been given to green spaces in urban areas, which not only increases pollution but also decreases the urbanization. Therefore, urban green spaces are more important to improve air quality and resident living standards. Over the given scenario and the rainfall event, a decline of the quantitative discharge parameters is evident, such as discharge volume (i.e., from 3.6 to 61.8) and the peak discharge rate (i.e., from 5.4 to 62.7%). The simulation results show that green areas give high satisfaction with low construction costs, which shows the superlative performance ratio of the examined measures. From the investigation, it is also recommended to have green areas and public spaces in impervious urban areas, which greatly reduced the runoff in the project area.
