A geospatial approach-based assessment of soil erosion impacts on the dams silting in the semi-arid region

Geomatics Natural Hazards and Risk, Journal Year: 2024, Volume and Issue: 15(1)

Published: July 9, 2024

Soil erosion significantly impacts dam functionality by leading to reservoir siltation, reducing capacity, and heightening flood risks. This study aims map soil within a Geographic Information Systems (GIS) framework estimate the siltation of K'sob compare these estimates with bathymetric observations. Focused on one Hodna basin's sub-basins, watershed (1477 km2), assessment utilizes Revised Universal Loss Equation (RUSLE) integrated GIS remote sensing data predict spatial distribution erosion. Remote were pivotal in updating land cover parameters critical for RUSLE, enhancing precision our predictions. Our results indicate an average annual rate 7.83 t/ha, variations ranging from 0 224 t/ha/year. With typical relative error about 13% predictions, figures confirm robustness methodology. These insights are crucial crafting mitigation strategies areas facing high extreme loss will assist governmental agencies prioritizing actions formulating effective management policies. Future studies should explore integration real-time advanced modeling techniques further refine predictions expand their applicability similar environmental assessments.

Quantitative assessment of morphometry and GIS integrated RUSLE model-based soil loss estimation from Pahuj river basin, central India

DELETED, Journal Year: 2024, Volume and Issue: 90(4), P. 1049 - 1066

Published: May 10, 2024

In this study the morphometric indices of Pahuj river basin (PRB) were evaluated by applying remote sensing and GIS. The Shuttle Radar Topographic Mission (SRTM) based 30 m digital elevation (DEM) data was used in order to extract parameters using standard methods. PRB covering an area (3648 km2) is controlled homogenous lithology geological structures. drainage density indicates that permeable soil with coarse texture dominantly occurring large low-lying flat areas basin.

Soil and organic carbon losses by water erosion in coffee-growing areas in southern Minas Gerais, Brazil

TURKISH JOURNAL OF AGRICULTURE AND FORESTRY, Journal Year: 2024, Volume and Issue: 48(3), P. 317 - 331

Published: June 6, 2024

Organic carbon performs essential functions in soils. Soils act as sources or sinks of atmospheric organic carbon. Agricultural management influences soil carbon, impacting climate change. One the crops most vulnerable to change is coffee. Brazil world's largest coffee producer, with a predominance under conventional system, sloping terrain and absence conservationist practices. The practices results an increase loss rates due water emissions, well reduction production. This paper aimed estimate losses by RUSLE farms southern Minas Gerais, southeastern Brazil. Data were obtained from fieldwork, laboratory analysis cartographic products. indicated, exclusively for crops, between 7 32 Mg 87 460 , respectively.
