- W4207036794 abstract "River water, the most important natural resource, also considered as a limiting resource in terms of growth and livelihood. Some prominent issues like water scarcity, water pollution, heavy metal pollution, and degradation of water biomes impacted the terrestrial and aquatic ecosystem with extreme severity. This chapter studied the concept of a modeling approach to analyze the status of hydrological regime of the Jumar river and its catchment area which lied in Ranchi district of Jharkhand, Eastern India. The sustainability of Jumar river was found highly sensitive to extreme events like water scarcity and drought conditions. The frequent droughts in summer and overflow in rainy season resulted in eutrophication, soil erosion and sediment pollution in Jumar river basin. This overflow in rainy season was caused due to inflow from non-point sources of water pollution. River water quality assessments and prediction can be done based on various qualitative factors like pH, turbidity, acidity, alkalinity, hardness, dissolved oxygen (DO), biochemical oxygen demand (BOD), chemical oxygen demand (COD). The tools which can be helpful in river water quality modelling were identified as statistical tools, geospatial tools, and technological tools. Some of the statistical tools like descriptive statistics (DS), principle component analysis (PCA), cluster analysis (CA), analysis of variance (ANOVA), multivariate analysis of variance (MANOVA), geospatial tools like geographic information system (GIS), remote sensing (RS), global positioning system (GPS), and technological modeling tools like artificial neural network (ANN), river sustainability Bayesian network (RSBN), universal soil loss equation (USLE), annualized agricultural non-point source pollution (Ann AGNPS), soil water assessment tool (SWAT) were already used in surface water quality modeling. These tools not only helped in understanding and simulating past and current datasets but also assisted in future predictions. Therefore, for understanding the Jumar river sustainability, RSBN model was reviewed using Bayesian network. The RSBN model offered a unique combination of parameters which include water quality and quantity, socio economic and other environmental factors. This framework may help water managers in decision making process for sustainable planning and management of Jumar river watershed." @default.
