er resource problems fall into three categories: too more piddle, too little wet, and poor-quality water. Flooding occurs when a rivers discharge cannot be contained within its normal channel. Todays fountains are more unfortunate in terms of property loss than those of the past because reality often remove water-absorbing plant ascertain from the soil and reconstruct buildings on flood plains. (A flood plain is the area bordering a river channel that has the potential to flood.) These activities increase the likelihood of both floods and flood damage. When a natural areaâ€"that is, an area undisturbed by macrocosmâ€"is inundated with heavy precipitation, the plant-protected soil absorbs much of the wastefulness water. What the soil cannot absorb runs off into the river, which may then swill over its banks onto the flood plain. Because rivers meander, the flow is slowed, and the swollen waters rarely cause significant damage to the surrounding area. (See Figure 6-12 on page 140 for a diagram of a representative river, including its flood plain.) When an area is devloped for human use, much of the water-absorbing plant cover is removed. Buildings and paved roads dont absorb water, so runoff, unremarkably in the form of storm sewer runoff, is significantly great in developed areas (Figure 10-5).

People who build homes or businesses on the flood plain of a river will most presumable experience flooding at some point (Figure 10-6). The briny goal of water management is to provide a sustainable supply of high-quality water. Sustainable water use means humans use water resources carefully, so water is available for forthcoming generations. Water supplies are obtained by building dams, diverting water, or removing salt from seawater or salty groundwater. Conservation, which includes reusing water, recycling water, and alter water-use efficiency, augments water supply and is an important aspect of sustainable water use. Economic policies are also important in managing water sustainably: When... If you want to get a full essay, order it on our website: Orderessay
