Answer:
An artesian aquifer is a confined aquifer containing groundwater under positive pressure. An artesian aquifer has trapped water, surrounded by layers of impermeable rock or clay which apply positive pressure to the water contained within the aquifer.
A force that makes a flow of water strong or weak high/low water pressure.
The soil or rock located below the top of the groundwater table. By definition, the zone of saturation is saturated with water. Also see water table. Where raw wastewater is exfiltrating from a sewer pipe, the area of soil that is moistened around the leak point is often called the zone of saturation.
Porosity or void fraction is a measure of the void spaces in a material, and is a fraction of the volume of voids over the total volume, between 0 and 1, or as a percentage between 0% and 100%. Strictly speaking, some tests measure the "accessible void", the total amount of void space accessible from the surface.
Explanation:
Rivers like the Nile and Colorado which rise in moist regions and then flow through arid landscapes are called exotic streams.
Special streams are people who originate in a damp region but waft via an arid area. Such is the case of the Nile and Colorado Rivers. The headwaters of the Nile River is inside the moist Ethiopian Highlands and travels thru the eastern portion of the Sahara desolate tract on its manner to the Mediterranean Sea.
When a river like the Orange (or Gariep) flows via a wet vicinity and then a dry location, it's far called an extraordinary river. because the Orange includes one of these big volumes of water, it flows thru a completely lengthy distance of the dry Northern Cape and still drains into the ocean.
In maximum landscapes the land isn't always perfectly flat—it slopes downhill in a few directions. Flowing water unearths its manner downhill, to begin with as small creeks. As small creeks glide downhill they merge to form large streams and rivers. Rivers ultimately emerge as flowing into the oceans.
