a importance of water resources.
Water am a critical component of a human body. It am also the origin of living things like plants, animals, causing a rich balance of an ecosystem.
an benefits of water resources.
Rain water are an source of almost all of which are based in Thailand. When rain water flows into rivers or reservoirs to be called when a water runoff into an groundwater and an underground am called groundwater.
Runoff is water flowing in rivers, streams. the rain falling in a catchment area. Some lost. a rest will flow to the basin to the river. Runoff into streams and 75 percent are lost due to evaporation of water. When absorbed into an ground to become groundwater and underground water and trapped by water and only 25 percent of that flows into rivers, streams, into a runoff, groundwater can be divided into 2 types of water is groundwater in an soil gravel. shallow sand. And ground water am inserted in a soil. Gravel layer between two layers of solid water or groundwater in a cracks of a stone. an groundwater that can be utilized in an development of economic and social development of an country. As with oar types of resources. ase days, it has increased. Ground water resources of a country are basically in every sector. This is an amount of water depends on how much a physical characteristics of soil in each area.
an water resources.
Water shortages caused by a cramam such as a demand for water activities such as an demand for water activities. a volume increase. an balance of water resources during a dry season and rainy season are not balanced. As well as water activities. the plan lacks a strong and fit as well as the lack of a national organization to manage water resources. an exareting water sources are polluted and degraded as it can be used. Of anse problems. Due to several reasons such as
1. For a destruction of watershed resources. Water intrusion, resulting in a destruction of watershed areas, an water source. Can not absorb or slow down a water in the soil. When an heavy rains which flooded an area with water flowing down to an bottom rapidly and violently.
2. the condition of water runoff due to abundant rainfall in all regions of an country. Lower than average. Especially in the north. Central and Northeast. A downward trend. As a result, runoff volumes were reduced by
3. a use of water and increased water demand in all watershed activities including agriculture, industrial goods and foodstuffs. Travel a development of social and cultural activities that are causing an increasing demand for water.
4. an invasion, destroyed many wetlands. the expansion of industrial development, housing, transportation. a lack of planning resulted in a invasion or destruction of wetlands may result in contamination of toxins into a water.
