The paper reviews the existing methods used in India for estimation of flow characteristics at ungauged sites. It focuses on low and high flows, long-term mean flow and flow duration curves. Since it lists the actual formulae, it can be used as a quick reference guide for selecting a suitable technique for various geographical regional and/or river basins in India.

Groundwater recharge processes in an urban area are different than in non-urban areas. There are various new components that must be considered in the case of urban groundwater recharge in addition to the natural recharge from precipitation. These various components are estimated in this study based on the water balance equation for the Hyderabad city of India. Initially, urban recharge components including leakages from water supply network and sewage networks were calculated. To estimate the natural recharge from precipitation, actual evapotranspiration and surface runoff were estimated using remote sensing and GIS techniques. Results indicated that the urban recharge component of groundwater was more than ten times greater than the natural recharge. The net urban recharge component of groundwater was estimated to be approximately 568 mm yr-1 and the natural recharge component was observed to be 53 mm yr-1. Water inflow and outflow components were also estimated to provide the complete scenario of the total urban water balance of Hyderabad. This analysis has provided the information regarding the extent and intensity of percolation of urban contaminants into the aquifer.

Intermittent water supply (IWS) is a typical characteristic of cities in developing countries like India. One of the factors responsible for IWS is unaccounted for water (UFW). Factors like increase in population, upward trends in water demand, water scarcity due to climate change, and asymmetric distribution of water resources are also equally important. However, social relations of water are poorly understood and camouflaged under technicalities associated with IWS. Thus, in this paper, we examine IWS in Indian mega cities and secondary cities with an ethno-economic framework by bringing the data together from various administrative sources like government agencies, allude to its parameters from logistical perspectives, e.g. distances, capacities, population strength, etc., and try to position the water issue with challenges associated with caste, class, gender, religion, region, and governance. The ethno-economic perspective is an attempt to not only complement but also supplement the scientific studies from other disciplines by understanding the real nature of demand and supply problems in urban water management. This paper demonstrates IWS as a multi-dimensional problem and stresses the human drivers of intermittency.
