The present study carried by a Wainganga river basin is of critical importance for Maharashtra to preserve its watershed, drainage, relief, soil, forests, wildlife, and tribal population dependent on it. Protecting the basin however does not seem to be priority for the state. The very lifeline of the Wainganga River is being subjected to growing pressure. Its flow has already been obstructed at several places with dams and barrages. By 2012 there were as many as 149 dams built in Wainganga basin. The river in its initial reaches flow westwards and thereafter southwards in M.P. State and continues to flow Southwards in Maharashtra State. Several studies related to different aspects of channel cross section and longitudinal profile river have been carried out from different parts of the country and abroad. Recent emphasis is placed on quantitative geomorphology of drainage basin by various methods and measures to establish the interrelationship of cross section and longitudinal profile river and to impact on river morphology. Water is not only for sustains of life but also determines the quality of life. Assessing water quality is important as quantity in water resources planning and management. It may be observed that the existence of human being a lot of serious problem to disturbance of quality and quantity of water. There are several reasons for scarcity of water and most important things to the increasing population and changing environment condition in the local as well as world level. For sustainable development requirement to that fresh water is indispensable for human survival. Water is being transferred to irrigation and urban industrial uses, putting additional stress on the performance of the irrigation sector. Keeping in mind the scarcity of water resources to cater to the multi various needs of the growing population along the Wainganga River with the vagaries of monsoon precipitation and dearth for quality of water. The purpose of the present research work is to describe the physical condition in Wainganga drainage basin as a system unit resulting from the interaction between landuse & landcover and topography, which is an impact of socio economic condition and surrounding area or region.

In this paper, the linear regression model using ANN and the linear regression model using MS Excel were developed to estimate the physico-chemical concentrations in groundwater using pH, EC, TDS, TH, HCO3 as input parameters and Ca, Mg and K as output parameters. A comparison was made which indicated that ANN model had the better ability to estimate the physic-chemical concentrations in groundwater. An analytical survey along with simulation based tests for finding the climatic change and its effect on agriculture and water bodies in Angul-Talcher area is done. The various seasonal parameters such as pH, BOD, COD, TDS,TSS along with heavy elements like Pb, Cd, Zn, Cu, Fe, Mn concentration in water resources has been analyzed. For past 30 years rainfall data has been analyzed and water quality index values has been studied to find normal and abnormal quality of water resources and matlab based simulation has been done for performance analysis. All results has been analyzed and it is found that the condition is stable.

The hydro geochemical features of Neyyar River for a period of one year from May 2015 to April 2016 were analyzed. Six sampling sites were fixed considering physiography and present landuse pattern of the river basin. The residents in the drainage basin are primarily responsible for framing a better landuse and thereby maintain a good water and sediment regime. Geospatial pattern of the present landuse of the study area indicated that the sustainability of this river ecosystem is in danger due to unscientific landuse practices, which is reflected in the river quality as well. The parameters such as hydrogen ion concentration, electrical conductivity, chloride, Biological Oxygen Demand, total hardness and sulphate of river water and Organic Carbon of river bed sediments were analyzed in this study. The overall analysis shows that the highland areas are characterized by better quality of water together with low organic carbon, which is mainly due to better landuse and minimal reclamation. The midland and lowland areas are characterized by poor quality of water with high organic carbon, which is due to high anthropogenic activities and maximum pollutants associated with the region together with the alteration in landuse from a traditional eco-friendly pattern to a severely polluted current pattern.

Much of the earth’s surface is covered by water. As was pointed out in the 2020 edition of the World Water Development Report, climate change challenges the sustainability of global water resources, so it is important to monitor the quality of water to preserve sustainable water resources. Quality of water can be related to the structure of water crystal, the solid-state of water, so methods to understand water crystals can help to improve water quality. As a first step, a water crystal exploratory analysis has been initiated with the cooperation with the Emoto Peace Project (EPP). The 5K EPP dataset has been created as the first world-wide small dataset of water crystals. Our research focused on reducing the inherent limitations when fitting machine learning models to the 5K EPP dataset. One major result is the classification of water crystals and how to split our small dataset into several related groups. Using the 5K EPP dataset of human observations and past research on snow crystal classification, we created a simple set of visual labels to identify water crystal shapes, in 13 categories. A deep learning-based method has been used to automatically do the classification task with a subset of the label dataset. The classification achieved high accuracy when using a fine-tuning technique.

Ambos Nogales

This article aims to analyze some basic criteria for a sustainable use of water in an international watershed shared by Mexico and the United States. The study area comprises the region of Ambos Nogales, which is located inside the Upper Santa Cruz River Basin. This portion of the watershed represents the main ecosystem and the main source of water for urban and rural populations located in this region. Following criteria of sustainability the authors revise and adapt to the case of Ambos Nogales, a set of guidelines proposed by the Pacific Institute for Studies in Development, Environment, and Security. These guidelines include the following elements: basic water requirements needed to maintain quality of life in the population and the health of ecosystems; water quality that meets certain minimum standards; human actions and their impact on long-term renewability of freshwater stocks and flows; collection of data concerning water resources, use and quality of water; institutional mechanisms to prevent and resolve conflicts; and a democratic process of water-planning and decision-making. These twin cities have a long history of cooperation and conflict linked to water resources, which makes available enough information to create a diagnostic about the water management inside a binational arena, and allowing to explore possibilities for a better water resources management under a sustainable regime and from an international perspective. Keywords: Sustainability, binational water management, ambos Nogales region.
