By gravity principally. Water from rain or melting snow on the hills runs off down-slope in the easiest way it can on its way back, eventually, to the sea, eventually carving channels (valleys) for itself. On the way it collects tributaries that may themselves have subsidiary tributaries feeding them. If the stream crosses a plain or forms a wide, flat-floored valley once it has descended from the hills, it will meander across what is now its flood-plain - its natural overflow area. Eventually the river meets the sea through a tidal estuary, and deposits eroded sediment it has transported from inland onto the sea-bed. In some instances, with low tidal ranges and currents, the silt may form a delta.

How can pollen be transferred by water?
By pollen being washed away down rivers to other plants that may feed from the river water
What role does the land have in the water cycle?
Land plays a crucial role in the water cycle by absorbing and storing precipitation as groundwater, which can later feed into rivers and streams. Additionally, plant roots help to regulate the flow of water and prevent erosion. Groundwater can also slowly release water back into the atmosphere through processes like transpiration.
Do rivers make lakes or do lakes make rivers?
Rivers can make lakes and lakes can make rivers.Rain, melting ice and springs make rivers. When a river gets to a wider, deeper part of its course, it has to fill this depression to the brim before any water can continue downstream. That is how a river makes a lake.When the water level gets as high as the lowest edge, water spills over and the river continues downhill.Or, in a depression in the land, small streams or underground springs may create a lake, feeding directly into it. Again, nothing happens until the bowl is completely filled with water. Then, at the lowest edge, the water spills over and a river heads downhill on its way to the sea. That is how a lake makes a river.
How do tributarys form?
Tributaries form through the erosion and transportation of sediment from higher elevations by flowing water. As water flows downhill, it carves out channels and collects smaller streams and rivers along the way, forming tributaries that feed into larger river systems. These tributaries help to increase the water volume and overall drainage area of a river.
Why did the 2011 Australian floods happen?
The main reason why the 2010-2011 floods happened in Australia is, quite simply, because of the unusual amount of rain. Australia spends many years in drought, often caused by the El Niño effect. When an El Niño occurs, changes in sea surface temperatures cause a shift in air pressure which, in turn, can result in climatic anomalies, such as severe droughts in Australia. These years are punctuated by years of normal rainfall, but occasionally, Australia gets the opposite to an El Niño, which is La Niña. This means that weather conditions, etc, are in reverse to those seen during El Niño, and Australia experiences far more rain than usual. Australia had been coming out of an El Niño for some time, which means that many parts of Australia had seen gradually increasing rainfall. The rainfall recorded in September 2010 made it Australia's wettest month overall in 110 years. Queensland already experienced flooding in early 2009 (at the same time that southern Australia had the terrible Black Saturday bushfires), and higher than normal rainfall in 2010, increasing towards the end of the year. By then, the ground was simply too saturated to hold any more water. Add to that the effects of the cyclone which crossed the north Queensland coast at Christmas time, bringing excessive rainfall to north and central Queensland, and the ground was waterlogged. (A similar pattern led to the Brisbane floods of 1974.) Radar images show how large the cyclone system was, even though it was only a category one cyclone, the lowest grade. Low wind speeds do not necessarily mean low rainfall, and in this case the cyclone brought large amounts of rainfall right along the coast. Some of the water runoff from the north flowed down through the inland river system; some of the rainfall fell into the catchment areas of coastal rivers further south. The rivers broke their banks more easily, and there was nowhere for the excess water to go. Rain continued to fall heavily throughout early January. On 10 January 2011, Toowoomba, a city which sits at an elevation of 700m at the top of the Great Dividing Range, received 150 mm of rain within a 40 minute period. The ground could not hold any more water. Water collected along the escarpment at the top of the range and created the wall of water, a 7m high inland "tsunami", that went through the city and down the range. This wall of water rushed through Lockyer Valley to the catchment areas of the main dam that protects the city of Brisbane from flooding, sending its capacity to 190%. The gates had to be opened, sending the equivalent of two Sydney Harbour's worth of water into the Brisbane River each day. This is largely why Brisbane and Ipswich flooded. An inquiry into the release of water from Wivenhoe is underway. Many of the river systems further west which were affected by the flooding which had occurred regularly through December and January feed into the Darling River, which then leads to the Murray River. The Darling River catchment, and catchments east of this, received more rainfall than its capacity can take, and as the floodwaters moved downstream, communities in New South Wales, western Victoria and South Australia were affected as well.
What body of water does the Volga river feed into?
Ths Caspian Sea
What point does the water cycle lose it's energy?

What process is needed for lake water to go to river water?
A lake has a limited quantity and the lake is fed from the spring underneath. Its unlikely that a lake can feed a river.
What bodies of water feed the James River?
The confluence of the Cowpasture River and the Jackson River. Larger tributaries draining to the tidal portion include the Appomattox River, Chickahominy River, Warwick River, Pagan River, and the Nansemond River.
What is the relationship between the water table and the flow of a river?
The water table is the level below the ground where soil and rocks are saturated with water. The flow of a river is influenced by the water table because it can affect the amount of water available to feed the river. When the water table is high, it can contribute to increased flow in the river. Conversely, a low water table may result in reduced flow in the river.
A river and its tributaries?
A river is a large natural stream of water flowing in a channel to the sea, a lake, or another river. Tributaries are smaller streams or rivers that flow into a main river. Tributaries feed water into the main river, helping to increase its flow and volume.
If we had abundant of rainfall to feed watershed why we experience drought some parts of the year?
Drought can occur even in areas with abundant rainfall due to factors such as high evaporation rates, poor water management practices, or uneven distribution of water throughout the year. In some cases, the timing or intensity of rainfall may not align with when or where it is needed most, leading to periods of water scarcity or drought.
