Waterpotential is caused by osmosis, gravity,mechanicalpressure, ormatrixeffects includingsurface tension. It is useful in understandingwatermovements withinplants,animals, andsoil. Word origin:potential » Late Latinpotentiālis, powerful, from Latinpotentia, power. Compare:Osmotic Potential. See also:o...
Matric potential (Ψm) is always negative to zero. In a dry system, it can be as low as –2 MPa in a dry seed, and it is zero in a water-saturated system. The binding of water to a matrix always removes or consumes potential energy from the system. Ψmis similar to solute potent...
water resource, any of the entire range of natural waters that occur on theEarth, regardless of their state (i.e., vapour, liquid, or solid) and that are of potential use to humans. Of these, the resources most available for use are the waters of the oceans, rivers, and lakes; other...
1965). Leaf water potential is assumed to represent the meansoil waterpotential next to the plant roots (Ameglio et al., 1999), and provides good indication of leaf water status. It is widely adopted for scheduling irrigation in various...
The potential of the private sector in combating water scarcity: The economics PeterDebaere,AndrewKapral, inWater Security, 2021 2Governments’ role in fighting water scarcity To understand the dominant role of the public sector and how to position the private sector, we first consider the economic...
Known to connote both tranquility and a sense of grandeur depending on their scale, indoor waterfalls offer enormous creative potential to innovative architects. Singapore’s Jewel Changi Airport, designed by Safdie Architects, sports the world’s tallest indoor waterfall, supplemented by a series of ...
Finally, a recent analysis of the potential impact of unprecedented drought in the African urban context has shown how increased water supply can exacerbate inequalities and worsen the impact of drought on urban communities65. This body of socio-hydrological literature, which our work contributes to,...
The findings of this study give an overview of the potential of different risk analysis methods. However, this synthesis will not present all the elements and further aspects of the different procedures, which would not be the aim here, but rather a means to enable water utilities which may ...
attributed to processes such as mechanical dispersion, chemical diffusion, andpreferential flow, each of which has the potential to complicate environmental tracer interpretation. Corresponding to the range of mixing that can occur, a broad range of definitions for groundwater age exist; these have ...
If the acidification potential of nitrogen is higher than the natural weathering rate of the soil forming bedrock, the soils acidify. To integrate all these aspects, an ecosystem-specific critical threshold is defined above which ecosystem damage is likely to occur. This is taken into account in ...
