Intermittent , temporary or seasonal rivers or streams cease to flow every year or at least twice every five years. Such rivers drain large arid and semi-arid areas, covering approximately a third of the Earth's surface. The extent of temporary rivers is increasing, as many formerly perennial rivers are becoming temporary because of increasing water demand, particularly for irrigation . Despite inconsistent water flow, intermittent rivers are considered land-forming agents in arid regions, as they are agents of significant deposition and erosion during flood events. The combination of dry crusted soils and the highly erosive energy of the rain cause sediment resuspension and transport to the coastal areas. They are among the aquatic habitats most altered by human activities. During the summer even under no flow conditions the point sources are still active such as the wastewater effluents , resulting in nutrients and organic pollutants accumulating in the sediment. Sediment operates as a pollution inventory and pollutants are moved to the next basin with the first flush. Their vulnerability is intensified by the conflict between water use demand and aquatic ecosystem conservation . Advanced modelling tools have been developed to better describe intermittent flow dynamic changes such as the tempQsim model.

(2019) state that "[o]ur results disprove the proposed link between ancient settlements and large rivers from the Himalayas and indicate that the major palaeo-fluvial system traversing through this region ceased long before the establishment of the Harappan civilisation." During

While the Indus remained an active river, the Ghaggar-Hakra dried up, leaving many sites undisturbed, which explains why such a large number of sites has been found. Late in the 2nd millennium BCE the Ghaggar-Hakra fluvial system dried up , becoming

The Brassy minnow ( Hybognathus hankinsoni ) is native to the intermittent Niobrara River, Wyoming. Redband trout ( Oncorhynchus mykiss gairdneri ) is native to intermittent desert streams of southwestern Idaho. The West Fork Smith River provides vital habitat to different species, including coho salmon, returning to spawn in Oregon. Cobitis shikokuensis (Hina-ishi-dojo) in intermittent rivers move into

The riparian zone of intermittent rivers can provide habitat and resources for a variety of organisms, and may also be an important source of nutrients for habitats downstream. The dry period of intermittent streams is ended by what is called "rewetting" or a wetting front. Rewetting is defined as the resumption of waterflow through the stream. This happens when
392-577: A small seasonal river. Nineteenth and early 20th century scholars, but also some more recent authors, have suggested that the Ghaggar-Hakra might be the defunct remains of the Sarasvati River mentioned in the Rig Veda , fed by Himalayan-fed rivers, despite the fact that the Ghaggar-Hakra had dried up by that time. The basin consists of two parts, Khadir and Bangar . Bangar are the higher banks that are not flooded in rainy season, while khadar refers to

At the time of the 2017 census, Khairpur had a sex ratio of 939 females per 1000 males and a literacy rate of 49.15%: 62.08% for males and 35.49% for females. 777,006 (32.31%) lived in urban areas. 796,830 (33.13%) were under 10 years of age. In 2023,
504-547: Is not enough inputs to sustain surface water. Streams in more arid regions stop flowing due to the depletion of water storage in the surrounding aquifer and channel banks. The diversion of water and impoundment for human use, such as for flood control and irrigation storage, have caused intermittency in many rivers that used to be perennial. This was the case for several large rivers such as the Nile, Indus, Yellow, Amu and Syr Darya, Rio Grande, and Colorado, which became intermittent during

The Hakra-channel is connected to paleochannels of the Sutlej and the Yamuna, which ended in the Nara River , a delta channel of the Indus River joining the sea via Sir Creek . The Sutlej changed its course about 8,000-10,000 years ago, leaving the Ghaggar-Hakra as a system of monsoon-fed rivers terminating in the Thar Desert. This Sutlej/Yamuna paleochannel streamed through Sindh , and its sign can be found in Sindh areas such as Khairpur , Nawabshah , Sanghar and Tharparkar . A large number of sites from

It is mentioned as a divine and large river, which flows "from the mountains to the samudra," which some take as the Indian Ocean . The Rig Veda was composed during the latter part of the late Harappan period, and according to Shaffer, the reason for the predominance of the Sarasvati in the Rig Veda is the late Harappan (1900–1300 BCE) population shift eastwards to Haryana .

According to Rajesh Kocchar there are two Sarasvati rivers mentioned in the Rigveda. The older one described in the family books of the Rigveda, which he calls Naditama Sarasvati , drains into a samudra . The newer one described in

Later Vedic texts record the river as disappearing at Vinasana (literally, "the disappearing") or Upamajjana, and in post-Vedic texts as joining both the Yamuna and Ganges as an invisible river at Prayaga (Allahabad). Some claim that

Many incised arroyos that are destructive to stream beds and adjacent man-made structures were formed as a result of drainage channelization and overgrazing during the late nineteenth century along with the influx of American settlers in the Southwestern United States. Glacial streams are considered intermittent streams as the flow intermittence fluctuates with solar energy input. Most glacial streams are alpine headwater streams that receive water from

Intermittent rivers are found on every continent, and may even be more common than perennial rivers. More than 30% of the total length and discharge of the global river network is estimated to be intermittent rivers. However, due to some low-order streams being difficult to categorize or track, this total could be over 50% when taking those into account. In

2016-409: The exact sequence of these changes and their dating have been problematic. Older publications have suggested that the Sutlej and the Yamuna drained into the Hakra well into Mature Harappan times, providing ample volume to the supply provided by the monsoon-fed Ghaggar.

Rewetting causes changes both in the dissolved nutrients in the stream, and in species compositions. During dry periods of intermittent rivers, terrestrial animals can gain access to resources and areas that were otherwise inaccessible, either due to natural or man-made obstructions. Additionally, when drying, these riverbeds often leave behind organisms, such as fish, which were unable to relocate in response to lowering water levels. These organisms are often used as

This is a direct consequence of the extensive networks of dams and aqueducts that were built for human withdrawal of water that used to flow into wetlands, deltas, and inland sinks. This phenomenon can be observed in the Colorado River, whose flow has decreased significantly since 1905. In recent years, several U.S. states and Mexico have used significant amounts of water for agricultural and urban uses, which caused flows reaching
