“…The runoff during the rehabilitation stage was lower than that of other mined areas (Loch, 2000;Martín-Moreno et al, 2016), such as the simulated runoff for open-pit coalmines in Chirimiri, India, with 413.3 mm annual runoff and an average annual rainfall of 1,303.4 mm, equivalent to 34.44 mm monthly (Nigam et al, 2017).…”

“…Environmental changes generated by surface mining, such as landscape modification, alter the slope and the physical and chemical properties of the soil and vegetation (Evans, Zipper, Hester, & Schoenholtz, 2015; Vilas Boas et al, 2018; Zhang et al, 2016) and are issues of concern (de Barros et al, 2012; Nigam et al, 2017). Bauxite removal disorganizes the geological materials of the original soils and may affect hydrological processes (Chaer et al, 2011), modifying the balance between seepage and runoff (Rubio et al, 2013).…”

Surface runoff from an area undergoing soil rehabilitation after bauxite mining in southeastern Brazil

Changing hydrological processes and soil characteristics are of major environmental concern in surface mining. Runoff may be the best factor for determining the efficiency of rehabilitation after this type of mining, and needs more in-depth studies, but the environmental factors require more attention in order to control that runoff.The objective of this study was to compare the runoff during post-mining rehabilitation after the extraction of bauxite with that before mining, and to identify the factors that most affect it. Runoff from before the mining operations and during the rehabilitation after those operations were collected in seven plots in the area of a bauxite mine in southeastern Minas Gerais State, Brazil. The physical-environmental and anthropic factors interfering with the runoff were characterized for both periods, and their results were submitted to principal component analysis to define the parameters, which most demand attention in the mining rehabilitation stage. This study provides the first records of runoff in the field in areas rehabilitated after surface mining in Brazil, where the runoff decreased (1.75-times or 42.79%) from 0.76 to 0.30% of the precipitation during rehabilitation, compared to the reference area.The total porosity, density, and resistance of the soil, associated with the maintenance of slope, surface roughness, and vegetation cover, are the factors demanding more attention during the rehabilitation stage of surface mining in order to minimize runoff.

“…However, later investigations [26] showed that smaller values of λ, e.g., λ = 0.05, give better results for the river catchment for which the investigations were conducted. Despite this, a value λ = 0.2 is still applied in many practical applications [27].…”

This paper presents a methodology of calculating the water transfer capacity of a dyke pumping station in flood wave conditions in order to improve its functioning, especially with regards to the safety of the areas being drained. The exemplary analysis was carried out for a pumping station situated on a small right-bank tributary of the Odra River in the southwest part of Poland, which, due to the inadequate capacity of its pumps, extensively flooded the surrounding areas in May and June 2010. Hydrological analyses were conducted in order to determine the rate of the designed and control flows using a spatial regression equation, and as a comparison, the rainfall-runoff method was also used. The corresponding flood-wave hydrographs were also determined, which included total precipitation using the German Association For Water Resources and Land Improvement (DVWK) method, effective precipitation using the Natural Resource Conservation Service curve number (NRCS-CN) method, as well as hypothetical waves using the instantaneous unit hydrograph (IUH) method. Flood-wave routing was carried out and alternative solutions for both the output of the required pumps and the retarding reservoir capacity were highlighted on this basis. The paper presents the possibility of a correct pump capacity selection, and in turn, the size of the pumping station retarding reservoir that results from this selection. This will enable pumping station exploitation costs or maintenance costs of the retarding reservoir to be considerably reduced.

A review of the literature published during year 2017 on topics relating to nonpoint source pollution (NPS) is presented. This article is written with a view to cater the need of nonpoint source pollution research and to summarize the new advancements in NPS control. Research developments on assessing, monitoring, and controlling the nonpoint source pollution are the main focus of this review. Future research topics related to NPS are also recommended.
