Drainage systems can impact the management of crops productions and the environment. Drainage functions are to collect surface water or ground water and direct it away to keep the ballast drained. The drainage must be able to protect the substructure from erosion or from loosing its stability and capacity. There are different factors that influence the choosing of drainage excavation areas, and they are discussed below in details. The article herein documents some factors to ponder when selecting the right drainage excavation site.
First of all the local state and federal regulations if they are the drainage is to be carried out is important to consider because there are many rules and regulations to be followed before carrying out the drainage in an area. Therefore, it is important that the owners of the land understand all the regulations before giving consent on the drainage process. The soil properties of that particular area should be important also because some soil layers restrict water movement and hence the soil type must be known properly to be able to design the drainage system in that area. The topography assessment of the soil should also be an important aspect because the goal of drainage is to provide uniform drainage and thus the topography must be considered.
The strategies of cropping are important to consider because they can help in changing the economic period payback of the drainage system so that there is higher yielding. Crops with higher yielding tend to be more beneficial than those with lower yielding so the cropping strategies should be well examined before carrying out the drainage excavation in an area. The maintenance needs of the drainage is also an aspect to be considered because like any other system the drainage system needs maintenance so that it can perform properly. The area to choose should be easy to maintain so as the management plan is good.
Another aspect is the environmental considerations. Drainage has very good benefits to crop productions and other operations but at the same time it has several consequences that are environmental. There is a possibility of excess nutrients being exported from drained fields which is a result of excessive drainage so before choosing the area for drainage excavation you should consider the environmental outcomes. Removing excess water from soil can help the soil to warm up faster in the farm to allow early planting of the crops and therefore allowing better yields from the farm and also reduce the soil erosion.
Lastly the economic analysis of the drainage should be an important factor to be considered because the economic importance or benefit of the drainage will depend on so many factors. The cost of the drainage processes should also be considered to avoid having losses economically since drainage can reduce the year to year variability in yields from land that is poorly drained. For better economic yields the best area for drainage should be chosen to avoid the environmental consequences and other economic losses.
