The water resources in Rajasthan State are facing a crucial stage even after average/good rainfall. Temporal distributions as well as the spatial variability of rainfall within the state were investigated by applying an analysis of variance (ANOVA) test. The effect of change in catchment characteristics and anthropogenic activities on overland flow are also investigated in this paper by applying a regression technique. Inflow to the surface water resources of the state is regularly decreasing. Time series analysis and sequential cluster analysis reveals that 1994 was the critical year, which divides the two consecutive non-overlapping epochs viz. pre-disturbance and post-disturbance. Due to increasing population and the subsequent increase in agriculture (specifically using groundwater sources) having increased catchment interceptions, there is a regular decreasing trend of surface runoff and surface water availability. The study highlights that, in spite of an increasing trend of rainfall witnessed during the last 100 years, inflow to the surface water resources of the state is decreasing at a fast pace owing to a decrease in the percentage area contributing to surface runoff.

Sustainable Water Supply

Bolivia is among the countries with the highest availability of freshwater globally. However, many of its natural sources are impacted by anthropogenic activities, such as mining. Water is intimately linked to public health and is essential to achieving sustainable development. It is necessary to preserve water resources by designing and validating monitoring programs that help control the quality of the sources that supply important population centers. The study area in this research is the upper part of the Milluni micro-basin, whose lagoon system supplies water for two large cities. Milluni is close to illegal and abandoned mining areas, making the region highly vulnerable to heavy metal contamination. This study aimed to optimize the resources available for monitoring Milluni. The frequency of monitoring was statistically determined, and the correlation between parameters measured in situ (pH and conductivity) and metal ion concentrations to determine low-cost indicators to monitor the presence of heavy metals. A multivariate analysis of friction of the results of the pilot year of the monitoring program designed for Milluni, considering the characteristics and economic limitations, is presented. An approximation of the quality of the surface water resources of Milluni is presented as a result of the monitoring operations.

Surface Water And Groundwater

Data-driven models derived from data science tools have been used to investigate water quality in some parts of the Niger Delta Region (NDR) of Nigeria. 11 communities were affected in this study. 11 water samples obtained from 25 available sources collected from January 2019 to December 2019 include rainwater, surface water and groundwater. These samples were analysed for their physicochemical and bacteriological parameters. The physical characteristics of the water points range from pH of 6.61-7.2, electrical conductivity (EC) of 450-1742 unit, the turbidity of 0.72-13.65 unit, and total dissolved solids (TDS) of 225-794. The chemical scientific dataset generated were subjected to several scientific data models such as principal component analysis (PCA), piper, Pie, Collins, and Schoeller interpretation. There is a piece of evidence that the water resources are potable in sections where Escherichia coli and total coliforms do not exceed the international and regional recommended limits of 0 per 100 ml of the sample. Also, the community water points are good for livestock and excellent for both recreation and irrigation purposes. Possible water contamination sources include faecal pollution from shallow wells and unconfined aquifers. Land use planning, enactment and implementation of environmental laws are necessary for this region to have effective surface water and groundwater resource management.
