Why exotic river flows throughout the year?
1.2. 7 (Periodic/Exotic) rivers flow all year round because they are fed by tributaries in high rainfall areas. 1.2. 8 (Permanent/Periodic) rivers are characteristic of interchanging seasons of high and low rainfall.
What is the meaning of ephemeral streams?
Ephemeral stream An ephemeral stream has flowing water only during, and for a short duration after, precipitation events in a typical year. Ephemeral stream beds are located above the water table year-round. Groundwater is not a source of water for the stream.
What is episodic river?
Episodic rivers never receive groundwater and only flow when there is an episode of heavy rain.
Why are the Tigris and Euphrates rivers considered exotic rivers?
The Tigris and Euphrates rivers are considered exotic rivers, meaning that they begin in humid regions and then flow across dry areas. Both rivers begin in the mountains of Asia Minor and flow to the Persian Gulf.
What are permanent rivers?
A perennial river is also called a permanent river. This means that it never runs dry but continues to flow all through the year. The height and flow-rate of a river are influenced by seasonal change ( heavy rains or long drought). Perennial rivers most often have stable sources that ensure their continuous flow.
What is a first order stream?
First-order streams are perennial streams--streams that carry water throughout the year--that have no permanently flowing tributaries. This means no other streams "feed" them.
Why is a river considered exotic?

What is a stream?

A stream may be permanent or seasonal depending on the source of its water and the climate and geography of its course.
What are the different types of streams?
Types of Streams. The stream can be broadly categorized as perennial or intermittent streams depending on the characteristics of their flow. Perennial streams are streams that flow throughout the year and are common in the humid area where the ground and surface waters systems are connected.
How do streams get their water?
Streams are important components of the water cycle. It derives most of its water from rainfall and snow. Most of these waters are taken up into the atmosphere through the process of evaporation and evapotranspiration. Some of the water sinks into the soil by infiltration to form the groundwater, much of which re-enters the stream. The rainwater may also flow off on the surface as runoff. The runoff starts as a thin film of water and combines with other runoffs to form sheet runoff. When the sheet runoff is concentrated in a channel, it forms a stream.
What is intermittent stream?
The intermittent streams are also referred to as seasonal streams. The streams are often dry during the dry season and are common in deserts. Other streams may only flow only during and immediately after precipitation. Such streams are referred to as ephemeral streams.
How are rivers formed?
Rivers are formed by the confluence of several streams and are larger, deeper, and longer than a stream and often empty into large water bodies such as oceans and lakes. Streams are smaller and shallower so that one can often walk across them without being swept away.
Why do streams form floodplains?
In between, the stream meanders due to erosion and deposition of bank material.
What is runoff in water?
The rainwater may also flow off on the surface as runoff. The runoff starts as a thin film of water and combines with other runoffs to form sheet runoff. When the sheet runoff is concentrated in a channel, it forms a stream.
