hydro-logictype: post-industrial waterfront strategyscale: 433 acresduration: 1 semesterskill development: post-industrial waterfront revitalization; multi-scalar, ecologically -centric design interventions; multi-modal transportation planning; vernacular design principals; brown�eld development accelerated research
hydro-logic proposes a recon�guration of the water’s edge
into a productive landscape. this will trigger a reindustrialization of the site,
capitalizing on the existing rail and warehouse infrastructure while
providing economic incentive to the mumbai port trust to open the land for integrated residential and commercial
development. the resulting urban form will respond to the con�uence between daily tidal �ows (water-in)
and modi�ed storm water runo� patterns (water-out), creating green infrastructure from which all further
development is generated. additionally, multiple building and
housing typologies are proposed, each responding formally to the
relationship between hydrological patterns and socioeconomic
conditions.

productive landscape reconstructing the edge the project proposes to convert, slowly over time, the existing hard edge sea wall which
currently traps runo� and damages mangrove habitats, to a soft edge interface between land and water. this allows tidal and seasonal hydraulic �ows to shape the edge, creating
a new boundary between land and water, enabling the functionality of the site year around. the soft edge capitalizes on both rainwater runo� (water-in) and tidal �ows
(water-out). enabling �ood mitigation and productive landscape elements. DISTRIBUTIONENERGY

island morphology and ecology mumbai has lost 40% of its mangroves and mud �ats in the last decade because of
development of new residential areas and the dumping of waste. the loss of these natural resources have an adverse e�ect on wildlife habitats and the �shing industry. it has also led
to an increase of inland �ooding and the siltation of the harbor.

transfer of development rights (tdr) is a current practice in mumbai. following this precedent an additional �oor space index
(fsi) bonus will be given to developers that accounts for the provision of productive elements on a parcel by parcel basis.
productive elements will be used for solar power generation, biosaline agriculture and water retention reuse.
