Background From rvhat began as the raison detre of urbanisation

civilisation. Rivers in lndia were sacred sites chosen

complexes and

cilgrimage sites, palaces and forts, capital cities and urban centers during successful reigns and periods in

it's necessary but we are not really sure what it is used for, so more often than not it is ignored and tends to

are probably one of the most historically and socio_ of settlements. They existed before we did, and they are the reason our cities are located where they are today, and have

Why then are we facing the unusual paradox of dirty rivers and faceless urban design? ln this article we present the approach that an adequate response to our rivers will define contextual urban form for our settlements and in turn improve the quality of Iife offer to the city dweilers making tndiin cities llu1y" 'livable'.

The withdrawal of its waters for human or related consumption has cost the river its natural ecological health. ln upstream section of the river, its flow is modified due to diversion of water in hydro-power plants, while in the downstream side, extraction for agricultural use further reduces the flow. The real havoc is unleashed by the untreated sewage being dumped incessantly and shamelessly directly into the river which is believed to facilitate the final

From

a

religious perspective, the Canges and

Yamuna are continually being used

for

religious

ablutions and other cultural activities while being declared unfit for bathing (CPCB 2313, p.10). While rivers must be used as a source of water for cities, it is necessary to evaluate the extent to which the flow of

the river can be altered from its natural state. Environmental Flows (E-Flows) are the required natural flows that are necessary to maintain the

ecology of the river while serving the dependent human populations. (WWF 2012, pp.4-10) These Ievels need to be maintained in order to provide water and long term ecological and economical sustainability.

2.5 Overuse during immersions/religious activities Often during mass bathing such as with the Kumbh Mela pollution levels spike dramatically. This sudden and large increase in pollution can have a profound toll on the local environment and the overall river ecology. (Kulshrestha 2006, p. 438) For example during the 2004 Ardh Kumbh in Hardwat total coliform levels post, the mass ritual bathing was 2.5 times more than before bathing. Out of 10 sample sites, 9 were unfit with pollutants well above the levels permissible for bathing. (Kulshrestha 2006, p.

our minds, the terrain which facilitated

the

establishment of the sacred or political centres, has

undergone irreversible damage

to

facilitate

increasing populations and human greed for space (Figure-2). The conscious or unconscious turning away from the river and related natural features by our town planners has given birth to an urban centre and people lacking identity. Therefbre, our cities and people today live in an unsual dichotomy of clean lvell maintained private environments and cluttered incoherent public spaces.

3.1 Respectingthe lndian context Many other cities in the west have channelized the

rivers that flow through their cities, making

a

conscious choice of land over water. This should however not influence the decision making for the Canges and Yamuna as these tropical rivers carry larger volumes/ are subject to monsoon flooding, have vibrant riverfront habitats and flood plains that offer immense oppodunities for seasonal agriculture (\tVWF 2012, p. 2).

Riverfronts in other major international cities are often dominated by luxury apartments and upscale businesses. This is not relevant to lndia as the

riverfront associations are rooted in a traditional Figure-2 : Change in the river Therefore, while remodeling the land is one of the lactors contributing to many urban disasters/ we remain oblivious of the thin thread with which our

urban existence hangs in balance. Specifically, limiting monsoon water levels and increased

development along the Canges and Yamuna

Annual monsoon flooding which can increase water levels by up to 2m also implies that these grand riverfront schemes are irrelevant (Morgan de Rivery 20O7, p.22). AIso to be noted is that many cities globally are already in the process of reversing the channelisation attempt to allow their rivers to 'live' agai n (ref

unique to the context of the Canga and yamuna river systems of the lndian sub-continent is the need of the hour.

The ghats, much like the social system, were dedicated to specific uses, sacred, crematory ablution, etc. There was a sensible relationship oi

their location upstream or downstream keeping the 'cuirent

government,s decision,

of revitallising the ghats along the urban rivers therefore, is a sigirificanirt"p towards reviving our urban lifeline.

While short stretches were developed into steps to ensure safe access to the river, there was no attempt

to tame the entire stretch of the flow. Flood plains and the related ecological processes were well understood and deeply respected. Recurrent alluvium richness added to ihe post monsoon agricultu-ral landscape and was used for crops making floodplains indispensable for sustaining an
