“…A constant influx of these resources is very important for the delta. Excessive consumption of fresh water, and inhibited sediment flow in upstream areas due to socio-economic activities and management policies (e.g., dams, water quotas), leads to decreased availability of these resources in downstream areas, which leads to water shortage (for human consumption, industrial, and agricultural use), salinization, erosion, and compaction in these regions (Joyce 1997;Ottinger et al 2013;Pillsbury 1981;Saito et al 2007;Woodroffe 2002;Woodroffe and Murray-Wallace 2012). Construction in and around the river (e.g., hydropower dams, river rerouting) further change river flow rates, and induce abnormal flood or drought events.…”

“…The impact of human activities can be felt in the disturbance of natural resources, such as the logging of coastal forest, the drainage of wetlands, and the redirection of the river water to name only few examples. Additionally, water-, soil-, and air pollution, as well as ground compaction due to underground oil, gas, or groundwater extraction are noted in many deltas globally (Anthony 2014;IPCC 2014a;Kuenzer et al 2014aKuenzer et al , 2014bPillsbury 1981;Syvitski 2008;Syvitski et al 2005Syvitski et al , 2009). The human induced sinking of many deltas is aggravated by sea level rise, prevalent at all coasts of the earth.…”

Coastal river deltas are densely populated areas and hotspots of vulnerability. The delta's ecological, social, and economic components are vulnerable to a wide variety of natural and anthropogenic threats. Sea level rise, climate variability, and rapid socio-economic development exert pressure on the already highly dynamic regions. To protect river deltas and their components, it is necessary to assess the degree of vulnerability so that mitigation efforts can be recommended to stakeholders and policy makers. Many such vulnerability assessments have been undertaken for river deltas. However, as vulnerability and related terms, such as resilience, coping-, and adaptive capacity only entered geosciences in the past decades, these terms are often used ambiguously. This makes it hard to compare existing studies, which not only interpret the related terms differently, but also consider completely different threats to deltas and their components, at different spatial and temporal scales. A comprehensive overview of studies addressing vulnerability of river deltas is missing. This paper presents a review, based on a consolidated set of definitions of vulnerability and related concepts in the context of coastal river deltas. All studies reviewed were categorized depending on their focus on either the ecologic, social, or economic component of river deltas, and were classified according to their spatial scale, temporal resolution, and numerous other research characteristics. Clear trends on dominant research foci in the field of river delta vulnerability could be extracted. Additionally, based on the findings presented here, recommendations for future assessments considering existing research gaps, are formulated.

“…There is a general tendency that the annual solute load increases with the annual runoff [21,22]. In other words, the more water that flushes the underground landscape per unit of catchment area, the higher is the amount of solutes carried away with the water draining that catchment.…”

“…Rising saline groundwater tables are a very serious environmental problem in many parts of the world (Hall and Gorgens, 1978;Peak, 1978;Pillsbury, 1981), threatening agricultural production, as well as the terrestrial (Heatwole and Lowman, 1986) and aquatic (Williams, 1987) ecosystems. One option to control rising saline water tables is to pump or drain saline groundwater and dispose of it into streams (Evans, 1989;Hart et al, 1990Hart et al, , 1991.…”

Abstract. The effect of saline lake water disposal from the Lough Calvert Drainage Scheme on water quality of the Barwon River, in south west Victoria, Australia, was investigated. The Scheme is used to regulate the levels of several saline lakes outside the Barwon's catchment. This study found that the disposal of saline lake water was associated with increased total phosphorus, PO4, TKN, suspended solids, electrical conductivity and stream discharge and lower NOx in the Barwon River. Thus, when disposing of saline water, factors other than salinity should be considered in order to prevent an impact on the aquatic environment. At present this is generally not done. The results are discussed with reference to the effects of saline water disposal on aquatic biota and how the effect of saline lake water disposal on water quality may differ from the disposal of saline groundwater.
