Environmental flows for the Yangtze Estuary based on salinity objectives

Effects of the shallow water table on water use of winter wheat and ecosystem health: Implications for unlocking the potential of groundwater in the Fergana Valley (Central Asia)

“…In other settings, salinity limits crop varieties suitable for irrigated soils and affects crop development and yield (Katerji et al, 2003). It also affects river, stream, and wetland ecosystems (Hart et al, 1990), impacts of climate change on river ecosystems (Suen and Lai, 2013), river diversions and ecology (Das et al, 2012), river environmental flow requirements (Sun et al, 2009), tolerance of macro-invertebrate and the ecosystem protection trigger values (Dunlop et al, 2008), sustainability of agricultural landscapes, carbon sequestration and biodiversity values (George et al, 2012), vegetation-groundwater interactions (Humphries et al, 2011), pesticide toxicity, ecosystem functions and ecosystem services (Schafer et al, 2012), bioavailability of Cu and Zn and other essential plant micronutrients (Speelmans et al, 2010), and causes changes in grain ultrastructure, amylase, protein and amino acid profiles under water, salinity, and combined stresses (Ahmed et al, 2013). These myriad ecosystem health linkages do imply that under shallow groundwater conditions salinity has implications for river basin health and ecosystems and thus imposes carrying capacity constrains in terms of water-savings and unlocking the potential of groundwater development for irrigation.…”

The Zooplankton Community and Its Relationship With Environmental Variables in a Highly Polluted System, Golden Horn, Turkey

“…Estuaries as transition areas between land and sea form aquatic ecosystems that are characterized as one of the most dynamic ecosystems by a variety of inter-related biotic and abiotic structural components and intensive chemical, physical and biological processes which influence species density and diversity (Aslan-Yılmaz et al, 2004;Telesh, 2004;Yüksek et al, 2006;Sterza and Fernandes, 2006;Sun et al, 2009). …”

Ecological risk assessment for water scarcity in China’s Yellow River Delta Wetland

“…Ecological risk assessment provides a scientific foundation for managing the risks that will result from such changes in projects designed to protect and conserve natural ecosystems and biodiversity; the importance of such tools has increasingly been recognized by both academic researchers and environmental managers. There are three main sources of risk that are commonly considered in wetlands research: heavy metals and nonmetal elements, such as Cd, Cr, Cu, Hg, Ni, Pb, Zn, As, Bo, and Se (Powell et al 1997;Overesch et al 2007;Pollard et al 2007;Suntornvongsaul et al 2007;Nabulo et al 2008;Bai et al 2010;Brix et al 2010); organic pollutants, such as heavy oil compounds and persistent organic pesticides (Ji et al 2007;Chen et al 2008;Dimitriou et al 2008;Rumbold et al 2008;Gao et al 2009;Yang et al 2009b); and natural parameters such as water availability and salinity (Speelmans et al 2007;Sun et al 2009;Xie et al 2011). Since water is the defining feature of wetlands, and is essential to their health, water risks take the form of too much or too little water-flooding and drought (Ni and Xue 2003;Smith et al 2003;Bouma et al 2005;Cai et al 2009;Huber et al 2009;Nicolosi et al 2009).…”
