Abstract
Guruvayur Municipality which is having high floating population and commercialization is facing water scarcity issues despite of having plenty of water assets. This requires immediate attention and formulation of water management policies. In this study water availability modelling was carried out for Bharatapuzha River from where water was supplied for Guruvayur Muncipality. The water supply network in Guruvayur Municipality was traced in detail. The water availability study was carried out using the software MIKE HYDRO RIVER which is a 1D river modelling software. Hydrodynamic modelling was carried out using 28 years discharge data from CWC station. The modelling was carried out for a river stretch of 50 km. The past and present water availability of Bharatapuzha River (focussing on the spot Trithala) was simulated using the model and the future water availability (till 2030) was predicted based on climate change scenario. The study also covers the analysis of discharge data of Karuvannur River from where future water supply schemes are proposed for Guruvayur Municipality. The study results revealed that the water availability in both the rivers considered showed a declining trend over the years. The possible reasons for the declining trend were: decrease in rainfall trend over the years, increase in temperature over the years, groundwater exploitation, change in land use pattern and sand mining. Thus the dependency on surface water is not so reliable. So the recommendation for Guruvayur Municipality is to go for sustainable management of water resources within the Municipality rather than depending upon the unreliable sources.
