Introduction

Introduction Almost all major cities in the world today, are facing immense complications in sustaining the constant demographic pressures, environmental hazards and large scale urbanization. Architecturally, it is no longer viable to integrate built and open spaces or generate usable spaces within the dense urban fabric of the city. These factors have a pernicious impact on the existing infrastructure as it fails inevitably to meet the basic requirements of livability. The city of Manchester in England, lies within the United Kingdomâ&#x20AC;&#x2122;s second most populous urban area and has a population of around 2.50 million people. Beswick, in East Manchester is taken as a test site for further study and analysis.

LAND USE

It is observed that the morphology has evolved and developed in clusters that show signs of similar typology.

Most of the morphology pertains to that of attached single/multi-family dwelling stating that the maximum land use is for residential purposes. Towers and bar buildings form only 3% of the total built mass within the tissue, which contradicts high densification. Almost 15% of the total built form are warehouses that need greater ground coverage and provide lesser opportunities

Conclusion The entire process of data mining and analysis set the basis for generating a set of design rules and principles for further experimentation. The comparison of the selected tissue with other urban cities created an understanding of how buildings, networks and population densities function at various scales in different scenarios. The primary inference from this section of data mining is that the connections and differences between the words typology and morphology in relation to the context of the site play a very important role in designing a high-density city system. The environmental study from data mining is adopted as the main driver of design as it is interesting to investigate the aspect of river flooding and integrate it with the built and open spaces within the test site. The initial idea that came out of the study was to design a high-density patch that would be qualitative in its spatial envelope, both built and open to being able to integrate with the concept of river water flooding situation.

CHAPTER II: Design Strategy

Design Ambition â&#x20AC;&#x153;To design a high-density urban tissue with maximum pedestrian mobility and minimum risk of river floods.â&#x20AC;? After the collaborative effort of data mapping and analysis, a patch of 1 sq.km. was selected from the site extent as a test site for experimentation. From the environmental data, it was evident that the River Medlock is prone to high risk of flooding, which passed through the centre of the selected patch. The main focus of this chapter is to study and analyse the site topography and target the issue of flooding to minimise the impact and accommodate higher gradient of density. Since the density distribution is in coherence with the building morphology, a Fig 15.

RIVER MEDLOCK The River Medlock is one of the three important rivers in Manchester namely Irk, Irwell and Medlock. These rivers pass through the centre of Manchester, with Irwell being the largest of the three while Medlock is the smallest. These rivers shape Manchester and the cityâ&#x20AC;&#x2122;s development. River Medlock rises in the hills of Strinsdale near Oldham and runs for 12.85 miles before the final mile flows into River Irwell at the southwest extreme of Manchester City Centre. The river is highly prone to flooding and displaces large volume of water on the land due to less depth of the river basin and low gradient of slope. The land around the river is primarily a wetland with insignificantly planned open space for public interaction or social activities. The population density around

TOPOGRAPHICAL ANALYSIS To better understand the flooding scenarios and the various levels of flooding,a detailed site analysis aiming to understand the geographical and topological aspects of the selected piece of land is carried out. Site sections - front

Traditional methods are adopted. Horizontal sections at 20-meter intervals are plotted and the topological profile of the site at each section is recorded. This process provides an accurate 3-dimensional reproduction of the site. Each section on the site and its attributes such as minimum, maximum and average slopes including elevation gain and loss are catalogued. The maximum and minimum values in each category are identified. This provides information regarding critical sections of the site that are most prone to flooding. This process proved to be acutely efficient as the data acquired from this technique aided the design process to a large extent, identifying zones that required mindfulness. Site sections - VIEW

Branching technique

To distribute the fluctuating water levels during floods, the river branching technique is adopted. The course of the River Medlock is analyzed. The radii of the meanders and the direction of the tangential flow at various points are recorded to find the optimum direction and curvature with which the river may be branched. The lowest points on site are established and mapped to create the branches. This helps to direct the water flow using mere gravitational force and helps the water level itself by distributing volume. Architectural Association School of Architecture Emergent Technologies and Design 2015-16

RIVER BRANCHING The branching of the course of the river helps distribute the volume flood water evenly across the site. This method ensures that river bank can adopt to various flood conditions. Each branch contributes to level the rising flood waters. These tributaries are mainly composed within the flood prone zones. 4 tributaries are mapped out using the lowest points on site to tackle a Target Volume of 100,000m3 of flood water.

DENSITY DISTRIBUTION

Density is distributed across the site combining two strategies. The first strategy involves increasing the density with increased distance from the river. The second strategy involves increasing the density along the Ring Road. Combining the two we see in the above figure that higher density is distributed along the ring road and lower towards the river branches. This increases the open spaces around the river, providing increased green spaces and increased connectivity to the surroundings.

An axial map layout for various iterations are generated and analyzed using various graph measures. Integration and connectivity is largely analyzed in this case as the design requires the interconnectivity of pockets of land and intergration of adaptable open spaces . Connectivity (the number of lines each line intersects with) both in terms of Axial Connectivity and Angular Connectivity are analyzed. This analysis shows that the networks well connected to each other creating

FURTHER DEVELOPMENTS

Further development of the project will focus on iterating smaller parcels of land to obtain better solutions at a local scale. Experiments will also focus of integrating more programmatic features into the building typologies. As the programs are predetermined it limits the solutions produced by the Generative Algorithm, future explorations will attempt at distributing programs using GA. Furthermore, as the building morphologies remain unexplored, investigations to integrate the building morphology with open spaces and fluctuating flooding scenarios will be executed. Even though the urban patch is well connected it lacks hierarchy, therefore developing a hierarchical network sytem would be beneficial.

The city is in constant transformation. Designing a city for an unforeseeable future may seem impossible. Strategic modeling with continual exchange of information with mutable and immutable conditions has become an alternative to conventional urban planning approaches and techniques. This process aims at designing a city that can endure time and change. The ambition was to plan and design an adaptive urban tissue, an amalgamation of multiple parts working together, a coherent system which could respond to various flooding scenarios. The solution arrived at was to distribute the flood water by branching the river having adaptable river banks that would also serve as public and recreational areas. The site was mapped and rigorously studied for topological and environmental conditions that could influence the location of the branching with the least intervention. Simulations of water flow also aided the process. These simulations were computationally heavy and very time consuming. Various revisions of the project produced an urban patch that had disconnected parcels of land which performed independently of each other. Networks were generated within every patch and the blocks were placed within the subdivided parcel of land. This essentially turned out to be a top-down process which is contrary to the bottom-up character of emergence. Although shortest path and

minimum spanning tree algorithms were used to generate networks within the separate parcels of land it lacked hierarchy and overall connectivity. The influence of the networks on the building morphology was very minimal as the various morphologies and their placement within each patch were predetermined. Predefined parameters such as density, building heights, typology and their spacing influenced the overall working and performance of the generated city. Complexities of blocks were lost as programs and functions were not assigned to them. This deterministic approach with the sequence of actions resulted in monotonous and homogenous solutions. The resulting urban patch also fails to integrate the river and its branches with the built form. Exploration of innovative relationships between the built form and water collection areas could have enhanced the interest and the complexity of the project. Analysis of the results produced suggests that the urban solutions and the architectural solutions are loosely connected leading to a less integrated approach. If this project were to be done again, a different strategy would be adopted. Different tools and strategies would be adopted to simulate topological changes as the previous simulations proved to be computationally heavy, time consuming and inaccurate. Generating boundaries and land masses in relation to the river bank. Planning strategies and computational design in which parts of the system are not separately developed but as an integrated process in which parts are develop together will be explored. This would involve the formation of hierarchical networks systems and blocks being highly interconnected determining the programs and functions of the blocks.

The overall project has been deeply analysed and evaluated, and it shows that there are three main aspects, which are topography manipulation, generating network system, and distribution of building morphology, that have similar problems when generating a whole system. Those problems are basically located in the lack of determining fitness criteria as well as in the linear process in every aspect. Also, because of all of the parts were treated in a separate sequence by their own logic and criteria, so eventually the relation of whole system become so limited. Since it was our ambition to makea river branches as a driver to generate our system, manipulating the topography become our first attempt to build an area for branching the river as well as for defining green corridors, by evaluating the lowest points in our patch. But due to the minimum criteria and no fixed variables, this process looks too random. Thus, the branching systems did not have a specific condition such as its size and the angle. Furthermore, instead of utilize our main attractor, the river branches, to grow our Architectural Association School of Architecture Emergent Technologies and Design 2015-16

other hand there is no hierarchy and adaptation on the patches. Learning from smart city, I came to the conclusion that the hierarchy of the network and how the network adapt to the different scenario is very important to predict the growth of the city and cannot be separated from other components.
