  • Assessment of Soil Erosion and Mapping Annual Soil Loss Using RUSLE Model With Geospatial Approach in Shimsha Basin, India
    Bharath A., Ramesh Maddamsetty, Uttam Pawar, Reshma T. V., Shubha Avinash
    Clean Soil Air Water, 2026
    Accurate estimation of soil erosion at regional scale is essential to preserve fertile soils. Assessing soil erosion is crucial to plan conservation works in a river basin. The Shimsha basin is predominantly an agricultural basin, which faces soil erosion issues. This research evaluates the soil loss in the Shimsha basin, Karnataka, India, using the Revised Universal Soil Loss Equation (RUSLE) together with geographic information system (GIS) methods and remotely sensed (RS) data. RS data are used to obtain the important parameters of the RUSLE model, whereas GIS is used for mapping areas that are susceptible to erosion. Input datasets of rainfall, soil maps, land use land cover (LULC), and digital elevation model (DEM) are employed to calculate the corresponding RUSLE model factors. In the GIS setting, these factors—topography, rainfall erosivity, erodibility of soil, cover management, and conservation practices—are computed and merged to evaluate spatial patterns of soil loss throughout the watersheds. The estimated soil loss in the Shimsha basin varies from 0 to 4669.4 t ha −1 year −1 , and the annual mean total soil loss has been approximated to 2.81 million tonnes per year and an average soil loss of 3.24 t ha −1 year −1 . The findings indicate that soil erosion rates are highest in intensively cultivated areas and mountainous regions that have sparse vegetation and steep slopes. RUSLE and GIS integration approach offers a dependable estimate of soil loss. The results help in identification of priority areas, enabling effective planning along with execution of sustainable soil management activities.

  • Evaluation of strength, durability, and microstructure characteristics of slag-sand-induced concrete

    Cleaner Materials, 2023
    This paper focused on the usage and behavior of slag sand by investigating the fresh, mechanical, durability, and microstructural properties of M40 grade concrete. However, in India, more research on the effect of slag on mechanical strength is needed with in-depth microstructure & durability investigation. To fill this research gap and promote slag sand usage, a systematic and scientific investigation was conducted in which 9 concrete mixes with partial and total replacement of fine aggregate with slag sand were prepared. Compressive, split tensile strength & UPV tests are performed at 3, 7, 28, and 90 days of curing to know the mechanical properties. Linear regression analysis is done to correlate and predict the strength of concrete using different mechanical properties. According to test results, workability and mechanical properties improve with the increase in the replacement of slag sand. Slag sand concrete forms a dense network at an optimum replacement achieving Maximum rise in strength of about 17 to 33 %, referring to the control mix resulting in an environmentally friendly material. Thereby reducing the disposal of industrial effluent. Conversely, increased replacement beyond 40 % of slag sand in concrete caused a reduction in the slump and mechanical properties with increased curing age. Microstructure results revealed the formation of CSH, CASH, ettringite, calcite, and good bonding with an aggregate. Slag sand tends to absorb more water with its increased percentage due to its shape, texture, and surface area, as evidenced in its SEM images & workability. The durability of slag sand concrete has performed better and is economically feasible than M-sand mixed concrete. Hence, recycling slag sand in concrete yields an economical, eco-friendly material and proves to be a robust substrate for various construction activities in sustainable waste management.
  • Spatiotemporal Rainfall Variability and Trend Analysis of Shimsha River Basin, India

    Environmental Science and Pollution Research, 2023
    Karnataka state has the second highest rainfed agricultural land in India, where agricultural output relies heavily on rainfall. The Shimsha basin, a sub-basin of Cauvery in the state, comes under a semi-arid region and predominantly consists of rainfed agricultural land. Rainfall patterns have changed dramatically with time resulting in frequent floods and droughts. Understanding the spatiotemporal distribution of rainfall and its change patterns in the area would benefit sustainable agriculture planning and water resources management practices. The current study aims to determine the variability and trend in rainfall. The daily rainfall data of the Shimsha basin from 1989 to 2018 is collected, and the annual, seasonal, and monthly rainfall totals and the number of rainy days are derived. All the time series are subjected to statistical methods to examine rainfall variability and trend. The mean, standard deviation, coefficient of variation (CV), and Standardized Anomaly Index are used for the preliminary and variability analysis, while the coefficient of skewness and kurtosis are used to understand the rainfall distribution characteristics. The homogenous and serially independent series are identified by homogeneity and serial correlation tests. The trend in the homogenous and serially independent series is identified by Mann-Kendall and Spearman's rank correlation tests, while the magnitude of the trend is quantified using the Sen's slope technique, and the trend change point is evaluated using the sequential Mann-Kendall test. Based on the study, the average rainfall in the study area is 801.86 mm, with CV ranging from 43.3 to 22.27%. The southwest monsoon (SWM) season brings the greatest rain to the basin, followed by the post-monsoon (PM), summer, and winter seasons. In the annual time frame, except one station, all other stations have shown significant or insignificant increasing trends. The seasonal rainfall has shown insignificant rising trends during the summer and winter seasons while insignificant increasing and decreasing trends during the PM season. The SWM season has indicated significant increasing trends, insignificant increasing and decreasing trends. Overall, the study area has noticed an increased annual and seasonal rainfall except for the post-monsoon season, during which the rainfall showed a considerable decline. The findings of the study are helpful in water resource management, agricultural planning, and socioeconomic development in the study area.

    The availability of productive land is significantly impacted by the global phenomenon of urbanization. The amount of land available for food production and other essential activities decreases as cities grow because the urban perimeter encroaches on rural and natural areas. Conducting research on urban sprawl analysis and land use land cover (LULC) change assessment is essential in ensuring sustainable urban growth. Bengaluru, a rapidly expanding metropolitan city, has a significant impact on the area around it, making it a prime location for this kind of study. In this study, authors sought to assess how urban sprawl affected LULC in the Bengaluru rural district that surrounds the city of Bengaluru. The study evaluated changes in LULC over a two-decade period using remote sensing data and GIS tools. Five LULC classes were used to categorize the study area: settlement, waterbody, vegetation, agriculture, and barren land. The maximum likelihood technique was used to classify Landsat images from three different time periods using the supervised image classification method in the ERDAS software. Accuracy assessment was used to gauge the classified images’ accuracy. The study’s important findings showed how the LULC classes in the study area have been negatively impacted by the urban sprawl. The study emphasizes the significance of ongoing research in LULC change assessment and urban sprawl analysis to ensure sustainable urban growth and safeguard the availability of productive land.

    Soils are the upper layer of the earth, which is formed by the weathering of rocks. Soils are thus the mixture of organic matter and inorganic constituents The fine-grained natural soil composite of clay minerals are the clayey soils. In Southern part of India, the most common type of soil found is laterite soil composed of red soil (RS) and black cotton soil (BCS). Laterite soil is also called RS as it contains iron oxide, which gives color to it These soil properties vary with the presence of moisture content (MC) as it absorbs water and holds within it
