Section 1 SITE ANALYSIS & INVESTIGATION
River Tame and Its valley The River Tame is the largest tributary of the River Trent. The river flows eastwards to the north of Birmingham City Centre and flows into a series of purification lakes at Lea Marston. After the lakes, the Tame continues to flow northwards, entering the River Trent. The Trent then flows north, finally flowing into the sea. The river through without of authority boundary, rising from Black Country to Birmingham, passing North Warwich and toward TameWorth. The catchment of the Tame contains a population of about 1.7 million people.

Lea Marston Lakes Oporation Lake 1 has an area of 25 ha and an average depth of 2.3 m. Almost the entire length of Lake 1 is split in half by a central berm, which provides the base for dredging. Lake 2A (Lake Lester) covers an area of 18 ha and its average depth is 2 m. Eighty per cent of the river flow passes through this lake with the remaining twenty per cent going down the existing channel.

Birds destination
Located in East Atlantic flyway, each year England is a destination of many millions mitigated birds, especially water birds. It would be a important site of international migratory birds. Take the advantage of birds mitigation to enhence the sense of place, make it is more special with birds watching. And be a role of International Wetland Park

Landscape and climate change It is widely accepted that our climate is changing and that these changes are at and climate change least in part a result of human activity. The impacts of these changes in the UK have been comprehensively researched by the UK Climate Impacts Programme (UKCIP) and, via UKCIP02, a number of forecast scenarios have been established for the coming century based upon different future emission trends. These include: — hotter, drier summers — warmer, wetter winters — an increase in the frequency of some extreme weather events — rising sea levels
Healthy wetland, healthy people A wide range of research show a strong case of the important of wetland habitat and why is essential to recreation and conservation wetlands. Scientists (Mitsch & Gosselink, 2015; Hume, 2008; Horwitz et al., 2012) agree that wetlands are “kidneys of landscape” in the planet because of their ecological functions such as supplying water, controlling flood, purifying water and protecting shorelines. Furthermore, wetlands are productivity hotpots of fauna and flora due to their extensive food chain and rich biodiversity that they support (Mitsch & Gosselink, 2015; France, 2002; Kirby et al., 2004). As well as a place for wildlife, France (2002) and Kirby (2004) highlighted other benefits of wetland for people amenities, namely: psychological support (aesthetics and wild open space), recreation, culture, and education. However, despite their values, wetlands are being drained by human activities, namely population expansion, urbanisation and agriculture (Ramsar Secretariat, 2012). For example, since the Industrial Revolution, English landscape lost 100,000 hectares wetland per year between 1840 and 1880 alone (Hume, 2008). As a consequence, many related environmental problems occurred, wetland-dependent species declined rapidly, and human health and well-being are affected (Horwitz et al., 2012; Ramsar Convention on Wetlands, 2018).
The invention of River Naturally river systems are in dynamic equilibrium (Das, et al, 2014, p.7). This means that the river system, if alterred by natural conditions, will always find and readjust itself, through process of sedimentation and erosion, in regards to profile, dimension, amd pattern to reach its former balance (Couture, 2008). The author integrates history, art, cultural studies, hydrology, and geography to tell the story of how rives have been culturally constructed and giving deeply knowledge about the river itself.
The Wetland centre The centre plays a role of rasing the knowledge about Wetland and promote Wetland conservation activities. Therefore a wetland centre or wetland education centre or wetland learning centre is defined by Wetland Link International (WLI – the global network of wetland centres) as ‘any place there is an interaction between people and wildlife and CEPA* activity occurs in support of wetland conservation’.
Reducing noise Summary There are several factors to be considered before deciding to create a tree and shrub barrier against noise. Noise is more effectively reduced by completely screening the source from view. A noise barrier should be planted as close to the noise source as possible. Wide belts of high-density trees and shrubs are required to achieve significant noise reductions. Effectiveness of noise reduction is closely related to the density of stems, branches and leaves. For all year-round noise reduction use broadleaved evergreens or a combination of conifers and broadleaved evergreen species. Soft ground is an efficient noise absorber. Cultivating ground before planting and the addition of well-rotted organic matter to the soil surface may also help to reduce noise whilst vegetation becomes established.

Section 3 DESIGN PROPOSAL “The earth does not belong to us, we belong to the earth� - Chief Seattle
Design brief Despite of the facts that the number of wetland in England has been decline year by year, Tame Valley and its wetlands is continuing a mysterious treasure that is hidden, unknown and isolated. Its extraordinary landscape that has a rich wildlife, culture and history is a potential place to creating an international wetland park that not only providing a place for wildlife and people, but also addressing these region environment issue such as climate change, food, water security, and stimulating health, contributing the economy and prompting a sense of place identity.

Strategy 1: Zoning During the planning process, it is essential to think about the various functions of the wetland educational centre. There will always be the need to strike a balance between the needs of the visitor and wildlife needs. Centre facilities need to work from a visitor perspective, but they must also compromise wildlife. One of the best ways to consider this is through appropriate zoning. Identify and zone areas based on their level of disturbance
36
37
Strategy 2: A living wetland “It will be as it should be�; this is the slogan that I always take into account during my designing process. Why? Because everything has their character, creating its identity as well as stand out of the crowd. Eventhough, design is a process of creative and modify aspects of a subjects, the design proposal aim to retain the most characteristic and highlight the most dramatic and impressive of the subject.

Strategy 3: Habitat creation & education According to the definition of Ramsar Convention and Wetland Link International: “Wetland educational centre is a place where there is an interaction between people and wildlife and regular CEPA (Communication, Education, Participation and Awareness) activity occurs in support of wetland conservation aims�, the role of education and raising awareness in WEC cannot deny. Therefore, base on its zoning, ecological function, and habitat, the series of educational facilities are allocated along the site to facilitate these purpose.
