A Semi – Distributed Water Balance Model for Amaravathi River Basin using Remote Sensing and GIS

Author(s)– Jenifa Latha.C, Saravanan.S, Palanichamy.K

ABSTRACT
Sustainable water management in a river basin requires knowledge of the water availability and water requirements of the basin in the present and future for various purposes. The complexity of the water system in the region can be understood by calculating the regional water balance in a distributed scale considering the factors that affect it.  Water balance is defined as the net change in water, taking into account all the inflows to and outflows from a hydrologic system. Spatial variation due to distributed land-use, soil texture, topography, groundwater level, and hydrometeorological conditions should be accounted for in the water balance estimation. However, conventional spatially and temporally lumped estimates of water balance do not help much in the planning and development of water resources in the water shed. This is an important and current issue in the socially and economically valuable Amaravathi River Basin of Tamil Nadu.  In this study, a spatially semi-distributed water balance model was developed to simulate mean monthly hydrological processes using landuse, soil texture, topography, and hydrometeorological data as input parameters in the Amaravathi River Basin, a semiarid region of Tamil Nadu in India. It is a physically based methodology for estimation of the average spatial distribution of water balance components. This model can be applicable in a public domain which can facilitate decision making. The water balance model is developed using SCS – CN (Soil Conservation Service – Curve Number) model to derive the runoff component and FAO-PM (Food and Agriculture Organization – Penman Monteith) model to derive the evapotranspiration component spatially with the help of remote sensing and GIS techniques.

Stochastic Production Frontier Analysis of Water Supply Utility of Urban Cities in the State of Madhya Pradesh, India
Author(s)- Amit Vishwakarma , Mukul Kulshrestha

ABSTRACT

In the Era of Globalization, Urbanization and Industrialization there is a major task of Public utility to fulfill the requirement of the people quatitavely and qualititatively in developing countries like India. In India till now performance assessment and efficiency evaluation of public utility (water supply and sanitation utility) by use of benchmarking methodologies, not in a regular practice. Benchmarking gives a clear idea about the significance of indicators which affect the efficiency of a utility directly or indirectly to the regulators, stakeholders and law makers. By applying Stochastic production function on Water utility of urban cities in the State of Madhya Pradesh we get the results that Municipality of Bhopal, Indore, Guna,  Jabalpur, Satna, Khargone, Neemuch and Vidisha urban city performed better and scored highest estimated efficiencies while evaluation is based on SFA production function.
