4 Ways to Control the Watershed
All must have seen the river before. But does anyone already know the definition of the river? The river is a large stream of water formed by nature, where river water flows from upstream, past the middle of the river, until it reaches downstream, until it ends up in the estuary.
The Watershed is a landscape bounded by topographic divide, ie ridge / mountain ridges that capture rainfall, store and then drain it through drainage channels to an estuary outlet. This is easy, if there are rivers in your neighborhood, and any rain drops will eventually flow into the river, meaning you are in the river basin.
Within a River Basin there are various ecosystems and land uses, such as rural, road, farmland, or forest. The figure that uses the land in a watershed is the people who live and utilize the watershed. Then if there is damage and disaster, who causes it? Of course people have a share in the damage and disasters that occur. Examples of disasters that occur are the lack of clean water and flooding. River water is getting muddy and floods are becoming more frequent when forest land is getting smaller. The relationship between forest and river water is about this. When the forest cover is so low, the rain drops directly into the available water channels to the river. It is not surprising that the soil is carried along by the river to form mud so that the water becomes less clean (although the water is less clean, also caused by the accumulation of garbage in the river). When the rainfall is high, while the water channel is not able to accommodate it, then there is a flood disaster. Therefore, it is very important to control the Watershed in order to repair the damage and avoid the disaster, by applying the good management of the Watershed.
Watershed Management itself is a human effort in controlling the reciprocal relationship between natural resources with humans in the Watershed and all its activities, with the aim of fostering the sustainability and harmony of ecosystems, and increasing the utilization of natural resources with humans in a sustainable manner.
Improve the quality of degraded (degraded) environments (diminishing and even loss of productivity and biological or economic complexity of a land) in the Watershed, for example by reforestation or reforestation, especially upstream, and using land according to their nature and capabilities. For example on a land with a slope of> 40%, it is not suitable for use as a seasonal cultivation plant.
Fostering the awareness and ability of the community to use and maintain the natural resources in a Watershed wisely, for example by doing counseling or training of land use is good.
Create and maintain artificial buildings that affect river flows such as dams, irrigation canals and Geomats – MacMat as you can see at https://www.maccaferri.com/us/products/geomats-macmat/. It can control the flow of water that drains into waterways and rivers.
And the most important but simple is, not littering! Because if you throw garbage carelessly, when the rain will come flow into the water channel to the river. This will lead to a blockage in the water channel and reduced water supply. By disposing of waste in place, the government (especially) will manage the waste properly.
