Nature's Pathways: Exploring the Rivers of Iran
What you will read in this article:
Depending on the source of nutrition and the duration of flow or the water supply of each river, they are divided into two categories: perennial and seasonal rivers. This is one of the features of Iranian rivers. Some of the rivers in Iran only appear on the earth’s surface during specific rainy seasons and depending on the amount of precipitation. These rivers are called seasonal or temporary. Their lifespan is short and depends on the time and reason.
Some rivers, considered the most crucial in Iran and necessary to the life of the life of the land, are alive and active all year round. Their source of nutribest, besides rainfalls, includes springs and the snow on the mountains. The water supply and flow of these rivers vary throughout the year, but they never permanently dry out, except during consecutive drought years and decreasing groundwater levels.
Another one of Iran’s perennial rivers is the Shahrchay River of Urmia. This abundant river has its source in the heights of the Dovecote mountains in Kurdistan and the border mountains of the martyrs. After passing through the city of Urmia and traveling a not-so-winding route, it empties into Lake Urmia.
Many of the rivers in central Iran are categorized as seasonal rivers. This means they are filled with water and flow during the rainy seasons, but during drier seasons, one can’t observe any flow.
