It took only few years to turn a naturally owing river into a drain. 17.84 k.m stretch of MithiNadi (river), an arterial river, running along north-south axis of Bombay (Mumbai) is facing the grimproblems of backyard atrocities. Finding its way through the odds of household garbage, industrialsewage, other pollutants and encroachments, Mithi river originates from the conuence of two essentialreservoirs; Vihar Lake and Powai Lake and merging with Arabian Sea at Mahim creek. The stategovernment is trying to rescue the river with their elusive plan but is being implemented with lessconcurrency in mind. The responsibility of restoring the river being shared between two authoritiesMumbai Metropolitan Region Development Authority (MMRDA) and BrihanMumbai MunicipalCorporation (BMC) directed by Mithi River Development and Planning Authority (MRDPA), givesa deceptive impression of revival and truth. Currently the authorities are resettling the informals,widening and deepening the river simultaneously building the retaining wall to safeguard the bank.The odds would be if both the authorities shell up a unique comprehensive plan under MRDPA forrestoring the river involving community. The aim of this report is to devise a 'design based' restorationplan to achieve long term riparian ecosystem and sustainability of Mithi river. The restoration strategiesfor urban rivers are understood by analysing the riparian ecosystem techniques through literaturereading on river -engineering, river -morphology and reviewing Los Angeles River, California-USA andCheonggyecheon River in Korea cases. Dealing with odds Mithi Nadi (river) is facing today and basedon socio-economic background and technical design aspects for the river, this master thesis proposes a3-Phase restoration model method to achieve the target. Phase-I would involve community awarenesswith participatory approach while building strong network, it also highlights a plan in segmenting theriver into 10 divisions for Phase-II surveillance and incognisant waste disposal methods. Phase-II of applyingriparian techniques will then be initiated bearing the narrow widths, existing residential sectorsalong the bank and current urbanization. Finally, Phase-III will commence with a community basedmonitoring plan underpinning Phase-I sectoral division plan for the river. The proposal is discussedusing SWOT analysis and whether the implications of the techniques are suitable in retrospective. Butnally it can be said that although there are several ways to restore a river, best strategy can only beachieved through community participation by fractioning their inputs appropriately.
