“…Thus, land disturbance associated with quarrying generally increases erosion and sediment yields and impacts on landscape sediment source patterns. In particular, surface mining areas can accelerate natural soil erosion, which increases sediment loads in rivers (Chalov, ; Chalov et al, ; Jaramillo, Baccard, Narinesingh, Gaskin, & Cooper, ; Pietroń, Chalov, Chalova, Alekseenko, & Jarsjö, ). Average accelerated soil erosion rates in Iran have been estimated at 23 to 25 t ha −1 year −1 (Afshar, Ayoubi, & Jalalian, ; Karchegani, Ayoubi, Lu, & Honarju, ; Rahimi, Ayoubi, & Abdi, ), but, importantly, the contribution of quarrying has not been determined.…”

The contribution of quarrying in the context of multiple catchment sources of fine‐grained sediment has rarely been investigated. This study assessed the relative importance of quarrying as a sediment source alongside rangeland surface soils and channel banks in a mountainous catchment in northern Tehran, Iran, using fingerprinting. Eight geochemical tracers were measured on 24 potential sediment source samples and four fine‐grained sediment samples. Statistical analysis to select three different composite fingerprints for discriminating the potential sediment sources comprised: (a) the Kruskal–Wallis H test (KW‐H), (b) a combination of KW‐H and discriminant function analysis (DFA), and (c) a combination of KW‐H and principal components and classification analysis (PCCA). A Bayesian unmixing model was used to apportion sediment source contributions using the three composite fingerprints. Using the KW‐H composite signature, the respective relative contributions (with uncertainty ranges) from channel banks, rangeland surface soils, and quarrying were estimated as 28.4% (10.9–46.8), 15.1% (6.6–22.7), and 56.6% (38.3–74.2), compared with 35.4% (11.9–60.1), 13.4% (4.1–22.2), and 51.3% (26.5–74.3) using a composite signature selected using a combination of KW‐H and DFA, or 20.7% (3.9–41.7), 17.2% (4.4–29.9), and 61.4% (44–78.8) using a fingerprint selected using KW‐H and PCCA. The different composite signatures therefore all consistently suggested that quarrying is the dominant source of the fine‐grained sediment samples. Potential mitigation measures targeting this land use include closure to permit revegetation to reduce exposure of bare surfaces to sediment mobilization. Limitations and uncertainties associated with this preliminary investigation are briefly discussed.

“…These loops can, for instance, be associated with catchment processes that delay the sediment delivery from the upper portions of a river basin (Hughes et al 2012). For instance, anti-clockwise loops can be a result of the delivery of fine-grained material from disturbed floodplains, including mining sites (Chalov 2014). …”

ABStrACt. Sediment monitoring and assessment remain one of the most challenging tasks in fluvial geomorphology and water quality studies. As a response to various environmental and human disturbance effects, the main sources and pathways of the sediments transported within catchments, especially most pristine small one, may change. The paper discusses state-of-the-art in the sediment budget research for small catchments. We identified nine independent approaches in the sediment transport assessment and applied them in 11 catchments across Eurasia in the framework of an FP -7 Marie Curie -International Research Staff Exchange Scheme in 2012-2016. These methods were classified as: i) Field-based methods (In-situ monitoring of sediment transport;-Soil morphological methods and dating techniques; Sediment source fingerprinting; Sediment-water discharge relationships), ii) GIS and remote sensing approaches (Riverbed monitoring based on remote sensing/historical maps; parametrization of the channel sediment connectivity; Sediment transport remote sensing modeling), and iii) Numerical approaches (Soil erosion modeling and gully erosion (stochastic and empirical models); channel hydrodynamic modeling). We present the background theory and application examples of all selected methods. Linking fieldbased methods and datasets with numerical approaches, process measurements as well as monitoring can provide enhanced insights into sediment transfer and related water quality impacts. Adopting such integrated and multi-scale approaches in a sediment budget framework might contribute to improved understanding of hydrological and geomorphological responses.

“…The maximum SSC in the DTJ is similar to that measured in other Mediterranean catchments with badlands, such as Isábena (López‐Tarazón et al , ), Araguás (Nadal‐Romero et al , ) or Ca l'Isard (Soler et al , ). It is also as high as concentrations measured in rivers draining mining areas (Pentz & Kostaschuk, ; Chalov, ).…”

Baseline to Evaluate Off‐Site Suspended Sediment‐Related Mining Effects in the Alto Tajo Natural Park, Spain

Mining is a human activity with considerable environmental impact. To evaluate such impacts, international laws require undertaking local studies based on direct sampling to establish baseline conditions of parameters modified by human activities. Mining takes place near the Alto Tajo Natural Park, where a suspended sediment concentration (SSC) baseline is required to determine whether mining affects water quality. To this end, we have monitored the Tajo River and its tributary the Tajuelo following Before–After Control‐Impact (BACI) techniques, recommended by Australian and New Zealand laws, requiring a specific method based on continuous monitoring and sampling to enable evaluation of SSCs. An SSC baseline has been defined at stations situated upstream of the mining area and compared with those downstream. The highest detected SSC upstream of the Tajuelo mines was 24 g l−1 whereas the highest simultaneous downstream value was 391 g l−1, more than one order of magnitude higher than the supposed baseline (24 g l−1). Additionally, this value is 1000 times more than the average concentration of 25 mg l−1, used by the European Union until 2015, to guarantee the quality of salmonid waters. Following a BACI approach, a statistically significant SSC impact has been identified. The mined areas are the only source that can explain this increase. This is the first instance that such an increase and baseline have been found using this method. BACI is a simple and reliable method recommended for studying degraded areas rather than an irrelevant, fixed standard as included in most international laws.
