Ephemeral streams
If mountain glaciers disappear there will be no source for many mountain streams, which will then dry up. Many rivers will be reduced in size as a result.
Water sources in grasslands can include rainfall, rivers, streams, lakes, and groundwater. The availability of water in grasslands can vary depending on the season and location. Grasslands are adapted to periods of drought and may have deep root systems to access water from underground sources.
Rivers usually begin as a trickle of water high in hills or mountains. Some come from rainwater or melting snow. Most emerge from underground streams, formed after rain or snow seeps into the ground then bubbles back to the surface. As the water flows downhill, the trickle swells into a stream and then, as side streams called tributaries join it, into a wider river.
Water erosion, particularly through processes like rivers, streams, and rainfall, is generally considered to be the most significant agent of erosion on Earth.
Rainfall causes floods when the volume of rain exceeds the capacity of the soil, rivers, or drainage systems to absorb or carry it away. This can lead to surface runoff, where excess water flows over land, accumulating in low-lying areas. Additionally, prolonged or heavy rainfall can saturate the ground, resulting in increased water levels in rivers and streams, which may overflow their banks. Urban areas with impermeable surfaces exacerbate the situation by preventing water absorption and increasing runoff.
The average rainfall on rivers and streams can vary significantly depending on the location and climate of the region. Rainfall typically replenishes river and stream flow, providing a consistent source of water. Areas with higher average rainfall generally have more water flowing in rivers and streams compared to areas with lower average rainfall.
The average yearly rainfall for streams and rivers can vary greatly depending on location. In general, streams and rivers in temperate regions receive between 30-60 inches of rainfall annually. However, this can be higher in tropical areas and lower in arid regions.
The percentage of groundwater in streams can vary widely depending on factors such as rainfall, geology, and land use. On average, it is estimated that about 40-60% of streamflow comes from groundwater. However, in some regions this percentage can be much higher or lower.

The amount of rainfall affects the flow of the streams within the watershed area, and ultimately how much water is stored in the watershed.
An ephemeral stream is dry most of the time and ionly holds water suring and after rainfall or snowmelt events. Streams in humid climates generally have water in them at all times.

Desert climates can have streams due to the presence of intermittent rainfall, which can lead to temporary water flow. Additionally, streams may originate from underground aquifers or mountain runoff, where water from snowmelt or rainfall in higher elevations flows into lower desert areas. These streams often dry up during prolonged dry periods but can provide essential water sources for ecosystems and wildlife when they are active.
