This entry provides the long-term average water availability for a
country in cubic kilometers of precipitation, recharged ground water,
and surface inflows from surrounding countries. The values have been
adjusted to account for overlap resulting from surface flow recharge of
groundwater sources. Total renewable water resources provides the water
total available to a country but does not include water resource totals
that have been reserved for upstream or downstream countries through
international agreements. Note that these values are averages and do not
accurately reflect the total available in any given year. Annual
available resources can vary greatly due to short-term and long-term
climatic and weather variations.
