Aug 25, 2006 · The water scarcity index is defined as Rws = ( W – S )/ Q, where W, S, and Q are the annual water withdrawal by all the sectors, the water use from desalinated water, and the annual RFWR, respectively. A region is usually considered highly water stressed if Rws is higher than 0.4 ( 7, 11, 14, 15 ). Deforestation has a variety of adverse effects on the water cycle. Without trees, the area will lack moisture and become a dry, arid desert. Furthermore, in the absence of rain, these areas will lose freshwater sources. As a result, the deforested land becomes a barren desert. Trees also store and release a large amount of carbon.A water year (also called hydrological year, discharge year or flow year) is a term commonly used in hydrology to describe a time period of 12 months for which precipitation totals are measured. Its beginning differs from the calendar year because part of the precipitation that falls in late autumn and winter accumulates as snow and does not drain until the …
