(b) rainfall patterns, and their influence on surface hydrology, and related hydro geology

Surface water is scarce in Botswana and less than 5 of the agriculture in the country is sustainable by rainfall.

The water level of the lake fluctuates significantly according to rainfall levels and the seasonal demands from the towns, villages and farms near the shore.

We went out in spite of the rain.

Their trip was postponed because of the rain.

Precipitation is moderate to heavy in most parts of the country the heavier rainfall occurs in the low lying hot zone.

We set out when the rain had eased.

Extensive areas of the Caribbean interior are permanently flooded, more because of poor drainage than because of the moderately heavy precipitation during the rainy season from May through October.

(a) the climate of the region, and its influence on rainfall patterns

So Brazil has 1,782 millimeters per year of precipitation of rain.

Rainfall is however highly variable, and droughts are common.

Rainfall is about 49 inches per year (120 cm).

The average rainfall is 500 600 mm per square meter.

Increased variability and intensity of rainfall as a result of climate change is expected to produce both more severe droughts and flooding, with potentially serious consequences for water supply and for pollution from combined sewer overflows.

This model relates the distribution of major ecosystems ( life zones ) to the climate variables of biotemperature, mean precipitation, and the ratio of potential evapotranspiration to precipitation (PET ratio).

Rainfall in most of the rest of the country runs between these two extremes.

Heavy rains are adding to the problems in Darfur.

After March, the rainfall rapidly diminishes and from May to September wet mists float from the highlands into the plateaus, with almost no rainfall during these months.

However, there are large variations in depth depending on the rainfall.

Rain is common throughout the year, with occasional flurries in winter.

Many parts of Mexico, particularly the north, have a dry climate with sporadic rainfall while parts of the tropical lowlands in the south average more than of annual precipitation.

Rainfall patterns will vary, and the Asian monsoon will become less reliable.

Rainfall in Canada peaked at 4.27 inches (108 mm) in Quebec.

Extreme flooding hit Dar es Salaam, Tanzania after unusually heavy rains saturated the East African capital city in April 2014.

The rainfall over the Red Sea and its coasts is extremely low, averaging per year.

Rainfall in Dammam is generally sparse, and usually occurs in small amounts in December.

And because of the rain until four o'clock in the afternoon, nobody went to the polling stations.

In the city of Bolzano, capital of the province, the average air temperature stands at and the average rainfall at .

Climate in this area has mild differences between highs and lows, and there is adequate rainfall year round.

The wettest place in Malaysia is Kuching, Sarawak with an average rainfall of with 247 days of rain a year.

The main water sources are surface waters.

The bad rainy season with rainfall far below the annual average occurred in summer 2006 07.

As the rainfall decreased, many of the cities further away from Lake Titicaca began to tender less foodstuffs to the elites.

Considerable variations occur because of local conditions that affect wind currents, however, and areas on the leeward side of the Guajira Peninsula receive generally light rainfall the annual rainfall of recorded at the Uribia station there is the lowest in Colombia.

Precipitation, however, has been increasing in the last few decades, with accumulated rain reaching per year.

There, an average of 180 days per year have precipitation, forty four days have fog, and only seventy two days are sunny.

The average annual temperature in La Rinconada is 1.2 C and the average annual rainfall is 707 mm.

Sufficient rainfall ensured that the water pumps on the east bank of the river were adequate to provide water to the village.

These zones, mostly characterized by arid and semi arid soils, receive little rain aside from some pockets of wetlands in the south west a Sahelian zone, which covers about 30 per cent of the territory.

22 2 Water

Reverse osmosis desalinates fresh water from ocean salt water.

Experiments in water management focus on the development of water harvesting techniques, the promotion of desalination plants and dam construction.

Water chemistry analysis is often the groundwork of studies of water quality, pollution, hydrology and geothermal waters.

The waters saw you, God. The waters saw you, and they writhed. The depths also convulsed.

The waters saw thee, O God, the waters saw thee they were afraid the depths also were troubled.
