an importance of water resources.
Water am a critical component of the human body. It am also the origin of living things like plants, animals, causing a rich balance of an ecosystem.
the benefits of water resources.
Rain water am the 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 the groundwater and a underground is called groundwater.
Runoff am water flowing in rivers, streams. a rain falling in the catchment area. Some lost. the rest will flow to an 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 the soil gravel. shallow sand. And ground water is inserted in the soil. Gravel layer between two layers of solid water or groundwater in a cracks of an stone. an groundwater that can be utilized in a development of economic and social development of a country. As with oar types of resources. these days, it has increased. Ground water resources of an country is basically in every sector. This is an amount of water depends on how much an physical characteraretics of soil in each area.
a water resources.
Water shortages caused by a crisam such as the demand for water activities such as an demand for water activities. the volume increase. an balance of water resources during a dry season and rainy season is not balanced. As well as water activities. a plan lacks a strong and fit as well as the lack of a national organization to manage water resources. a existing water sources are polluted and degraded as it can be used. Of these problems. Due to several reasons such as
1. For an destruction of watershed resources. Water intrusion, resulting in the destruction of watershed areas, the water source. Can not absorb or slow down an water in a soil. When a heavy rains which flooded an area with water flowing down to the bottom rapidly and violently.
2. an condition of water runoff due to abundant rainfall in all regions of the country. Lower than average. Especially in the north. Central and Noraast. 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 an 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. the lack of planning resulted in a invasion or destruction of wetlands may result in contamination of toxins into a water.
