Distribution of trace metals in the Odra River system: Water–suspended matter–sediments

Extensive investigations of trace metals concentrations in water, suspended particulate matter (SPM) and bottom sediments of the whole Odra River system were carried out over the years 1997–2000. The vertical distribution of selected metals and their mobility were also studied in the sediment cores from upper and middle river sections. Significant levels of metal contamination were found. Median concentrations (Cd, Pb, Cu, Zn and As) in the SPM and sediments were (mg kg⁻¹) 7.1 and 8.9 Cd, 128 and 146 Pb, 81 and 119 Cu, 1198 and 1204 Zn, 48 and 54 As, respectively. The highest metal pollution of the Odra River solids was found with cadmium, zinc, lead and arsenic, showing high similarity in their frequency distributions in both SPM and sediments. Cd, Zn and As appear to be of particular concern because of the high levels, that appear to be bioavailable, and their high mobility. The exchangeable and carbonate chemical forms of Cd and Zn reached up to 50% of their total amount. Besides the determination of total metal concentration, the metal chemical forms in river solids were investigated. The results of very wide studies of the Odra River system through 4 years suggest that metal pollution decreased, especially for Zn, Pb and Cu. Among all metals studied in the Odra River sediments, substantial reductions of Cd contamination were observed neither in the period after ’97 flood, nor if compared with the earlier results obtained before ’97. No essential differences of the metal contents were observed among the samples for the same river compartment, from the same locality, taken within the five sampling campaigns. The pattern of spatial and vertical metal distributions in the river solids indicates that a variety of sources might be responsible for the contamination; very intensive, historical and current mining and smelting activities probably are the most important ones.     

Development of an integrated conceptual model for the rational management of the transboundary Nestos River, Greece

This paper provides a detailed analysis of the geologic, hydrologic and hydrogeologic characteristics of Nestos River basin, which is formed within the Greek mountainous part of the river. The quantitative analysis was mainly based on the data of the river flow in different gauging points across the rivercourse as well as on the data of groundwater discharge from karst springs of the mountainous area while important conclusions were made regarding the hydraulic connection between the surface waters of the river and the groundwater of the karst aquifers of the basin. The qualitative analysis has shown that the quality of both surface waters and groundwaters of the investigated basin is high, whereas, no sources of contamination were indicated during this research. The possible effects of the two large dams of Platanovrisi and Thesavros are also analysed as they strongly affect the quantitative and qualitative regime of the river delta.     

Temporal and spatial variations in water flow and sediment load in Narmada River Basin, India: natural and man-made factors

The Narmada River flows through the Deccan volcanics and transports water and sediments to the adjacent Arabian Sea. In a first-ever attempt, spatial and temporal (annual, seasonal, monthly and daily) variations in water discharge and sediment loads of Narmada River and its tributaries and the probable causes for these variations are discussed. The study has been carried out with data from twenty-two years of daily water discharge at nineteen locations and sediment concentrations data at fourteen locations in the entire Narmada River Basin. Water flow in the river is a major factor influencing sediment loads in the river. The monsoon season, which accounts for 85 to 95% of total annual rainfall in the basin, is the main source of water flow in the river. Almost 85 to 98% of annual sediment loads in the river are transported during the monsoon season (June to November). The average annual sediment flux to the Arabian Sea at Garudeshwar (farthest downstream location) is 34.29×10⁶ t year⁻¹ with a water discharge of 23.57 km³ year⁻¹. These numbers are the latest and revised estimates for Narmada River. Water flow in the river is influenced by rainfall, catchment area and groundwater inputs, whereas rainfall intensity, geology/soil characteristics of the catchment area and presence of reservoirs/dams play a major role in sediment discharge. The largest dam in the basin, namely Sardar Sarovar Dam, traps almost 60–80% of sediments carried by the river before it reaches the Arabian Sea.     

南水北调地下水回补对潮白河冲洪积扇中上部地表形变响应及控制因素

2014年南水进京后,持续开展地下水回补对于遏制和减缓地面沉降发展起到重要作用,但地下水回升由此带来的不同区域、不同层位的地面沉降与回弹机制及其控制因素尚不明确。深入探讨和研究回补时间、回补量、回补地点与水位及地表形变之间的关系,了解地表形变发生机理和识别主控因素,为后续如何科学回补,发挥最大化水资源回补效益、对地面沉降防治和超采区治理具有极其重要意义。本文以潮白河冲洪积扇中上部区域为例,采用永久散射体差分干涉测量（PS InSAR）技术获取研究区地面沉降形变信息,并结合区域分层地下水位动态变化、分层沉降变化等多手段进行耦合,查明研究区地表形变与多因素之间的响应与控制因素。结果表明:南水持续回补导致区域地面沉降减缓,并在牛栏山地区出现地表抬升,抬升范围也随着水位上升逐渐向中下游扩展,2022年最大回弹速率达46.9 mm/a;地表形变具有明显的受断裂所控制的第四系沉积差异特性,以黄庄—高丽营断裂、顺义断裂和南口—孙河断裂所分割的后沙峪凹陷范围内变化明显大于其他地区;地下水位变幅与富水性差异决定水位上升范围与响应变化,而沉积构造作用所造成第四系沉积差异在地下水流向上具有一定控制作用。结果为地面沉降防控和机理研究提供理论和科学依据,同时也为后续开展地下水科学回补和方案优化提供指导和借鉴。
