The Tigris-Euphrates Rivers:
The land between these two rivers was called Mesopotamia, which literally means “between the rivers.”
People developed the area’s first cities here about 5,000 years ago.

VA #10 Winter Floods in Mesopotamia
Winter Floods in Mesopotamia
Visual Aid
The Flood Cycle:
There were two flood times in Mesopotamia:
Winter (November–February): Winter was the rainy season, but rain was not heavy and it came in short showers. Rain was heavier in the north. The rain caused the rivers to rise a little at that time of year. The weather was cold and snowy in the mountains, at the headwaters of the rivers.

Spring Floods in Mesopotamia
Visual Aid
VA #11 Spring Floods in Mesopotamia
11
Spring (March–May):
Spring was the major flood season in Mesopotamia. The snow in the mountains, in what is now known as Turkey, melted and the water flowed downhill. The rivers rose by several feet or meters. Spring was also the time of harvest. This meant that the water usually came too late to help the crops grow. Sometimes the floods even ruined the crops.

VA #12 Floods Help Renew the Soil
12 Floods Help Renew the Soil
Visual Aid
Usually, rainfall in Mesopotamia was very low. Once every three or four years, however, there was a lot of rain and the Euphrates overflowed its banks, leaving rich silt on the surrounding land.
Overall, flooding was irregular and unpredictable. It was hard for people to plan around the flooding.

VA #13 Summer in Mesopotamia
Summer in Mesopotamia
Visual Aid
Summer (June–July):
Summer in Mesopotamia was hot and dry. Temperatures reached over 140° F (60° C)! There was little rain and so river levels dropped. But rivers could suddenly flood if there was rainfall up river.

Fall (August–October):
Mesopotamians planted crops during fall. River levels continued to drop to a low in November. People hoped for enough water for a successful winter harvest… but not too much water.

Other Seasonal Changes in Mesopotamia

Other Seasonal Cycles:
Bird Migration: In spring and fall, birds such as storks, geese, and pelicans stopped to breed in the marshes of the Tigris and Euphrates. These birds were on their way between Europe and Asia. Why would they migrate at this time of year?
Pelicans: These birds eat fish. In winter, some fish tend to stay closer to the riverbed because it is warmer than it is at the water’s surface. The fish get oxygen from the plants at the bottom of the water. When fish swim deeper in the water, it is harder for pelicans to get enough to eat.

VA #16 Onager Migration
16 Onager Migration
Visual Aid
Onager:
This animal is a cousin to the donkey and horse. Today, the onager is endangered and its range is very small. Onagers need water and grass. After rainy periods, they used to travel in herds of 50 to 100 to their winter feeding grounds. In the summer, Onagers looked for watering holes.
Onagers mate between April and October (depending on where they live). Females give birth after 11 months to one foal. Onagers change color by season, too; they are reddish-brown in summer and yellow-brown in winter!

The Nile River:
The Nile is the longest river in the world. It travels over 4,100 miles (6,600 kilometers) through northern Africa. The most important portion for agriculture is 750 miles long from the first cataract to the mouth of the river.The Nile watershed takes up 1/10 of the continent of Africa.

The Cycle Begins…
Early Summer (June): Heavy rains in central Africa and Egypt led to Nile floods.
Late Summer (July–August): Like clockwork, the Nile flooded its banks late in the summer. The river left rich, black sediment after flooding.

VA #20 Fall in the Nile River Valley
20 Fall in the Nile River Valley
Visual Aid
Fall (September–October):
Thanks to the floods, the water level of the Nile was at its highest in the fall, fertilizing the soil. The higher the flood, the better the harvest! However, high floods could also create problems, destroying villages and leading to late planting and harvest.

Other Seasonal Cycles:
Crocodiles: Crocodiles thrived in swampy areas.
These reptiles breed in July. A female Nile crocodile builds her nest in holes near the river—but far enough away that her eggs are safe! She lays 50 to 60 eggs in the fall. In November, hatchlings emerge from the eggs. The mother crocodile often carries her babies in her mouth for their first swim.

River hippos: These large animals spent most of their lives in the water.
Most female river hippos get pregnant at the end of the rainy season in the summer. Most births occur in late winter or early spring. Baby hippos are born and nurse underwater.

Visual Aid
Papyrus: This plant grew in the water. It could reach 15 to 25 feet (0.3 to 0.6 meters) high. It is now extinct in Egypt. Papyrus had many uses in the daily life of ancient Egyptians. The flowers decorated shrines to the gods. The roots were used for fuel and to make utensils. Boats, sails, sandals, mats, and paper were made from the stem. People even ate papyrus! It grew year-round and was harvested between October and December.

Nile perch: These giant fish of the Nile laid eggs all year, but laid most during the rainy season of summer, especially in June.
One fish can lay up to 16 million eggs per cycle! Nile perch kill and eat other fish, even their own babies. They can grow up to 400 pounds (181 kilograms).
