HYDRAULIC WORKS, HISTORY, IMPORTANCE AND INTERESTING DATA

in #science6 years ago

Since ancient times, human beings have seen the need to take full advantage of the water resources that have been available to them, in order to be able to supply themselves in the development of different types of primordial activities, such as the settlement of populations in certain geographical areas. areas, where undoubtedly required the execution of jobs for the livelihood of the inhabitants, such as agriculture, livestock and mining. In this sense, it is important to note that in this context, many works were constructed whose objectives were not only the capture and use of the aforementioned resources, but a part of them was built with the function of providing adequate drainage in an area determined at the time of any storm.

Among these types of works are:

The aqueduct of Segovia, Spain, was built according to historical records, at the beginning of the second century after Christ, this imposing work like others of similar characteristics, formed part of structures designed by the Romans, whose purpose was the transport of Water flow from the point of capture of the liquid to various sectors of a populated center, running on land of variable topography. The images correspond to the aqueduct located on a busy street of Segovia, it should be noted, that in the year 1985 was declared by the UNESCO next to the old zone of the city, like historical patrimony of the humanity.

The cisterns, are hydraulic structures built below the surface that allow the capture and storage of water, had the objective of supplying depending on their capacity, a nearby urban area or territories where the agriculture, livestock or other activities. At present, the design of these structures has varied according to the type of soil, construction material and the required capacity, suppressing in most cases, the construction of porches inside the cistern. In considerable parts of the planet, they are known as underground tanks. The image shows the cistern of Theodosius in Constantinople, Turkey and the second, the cistern of Fuentealbilla in Spain.

Based on the above, it can be defined to hydraulic works as all those structures formed by a variable number of elements, which have the objective of having or exert a control on a certain fluid in order to generate a Benefit to a collectivity, either by providing protection against floods, supplying the population with water service, generation of electric power through hydroelectric plants, among others.

With the course of time and in the context of the emergence of new needs, the implementation of new techniques and technologies in the planning and execution of these projects has proved indispensable, with the unquestionable aim of obtaining more efficiency and for To allow a harmony between the development and the sustainability of the environment. This innovation has been made present, in the use of new building materials, process automation, in the physical characteristics of the structures, and in the purposes for which they are built, where not only is it limited to the supply and Security, but also includes sports.

Emphasizing the sustainability of the environment, from about the nineteenth century, when modern environmental engineering began to be used in projects to improve the quality of life, has been focused, in thoroughly investigating the development of all Hydraulic projects, being these causes in certain occasions of ecological damage in several regions of the planet. With regard to this, various institutions and government agencies have formulated a significant number of regulations that can directly alter or vary the original approach of such a work. One of the regions where there have been considerable cases of this kind is in South America, and it is not surprising or questioning that with the great geographical attributes of the region, we want to make the most of the availability of natural resources, including freshwater, and obtaining through the latter, sources of supply of the vital liquid, as well as a great electric potential through hydroelectric plants, necessary for the sustenance and development of the population in general.

However, in deepening the legal arguments that have been created, one can find the regulations of each of the ministries responsible for the preservation of the environment, the international codes or agreements that have been signed by groups of Nations (World Nature Charter, United Nations Framework Convention on Climate Change-UNFCCC) and related local and national regulations to provide protection for the fauna, flora and native populations that are based in this Territory.

In the Organization of American States, cases have been taken on the conservation and due exploitation of the natural resources found in the different countries that are part of the American continent.

In addition to this, it is necessary to point out that the rules do not cover only the environmental but also the structural, this, with the aim of complying with the existing safety standards, to which like any other type of civil work must be submitted. These regulations are mainly focused on ensuring good quality both physical and chemical of the materials used that compose the structure, implement and evaluate the analytical methods of design that are used by the designer, encourage Drafting of manuals for the inspection of structural works, the consideration of seismic risk that is present in a specific region, the establishment of economic and penal sanctions to those responsible for breaches or incidents occurring in Facilities, among others.

On the basis of the above, the need for promoting the development of hydraulic engineering projects is notable, where the geographical conditions can be maximized, and in an integral way, provide benefits to the Collectivity in general. In this order of ideas, the challenge grows for all those who venture into engineering, to investigate in depth the innovations that can be implemented through the use of new technologies, other types of machinery, new constructive methods, among others.

The images correspond to the viaduct over the River Deba, in Bergara, Basque Country, Spain. One can appreciate the use of the constructive method used in this type of structure, which consists of placing the different parts of the board of the bridge, by means of a shoring supported on hydraulic jacks, in such a way that no greater affectation is generated in the lower area, thus avoiding temporal affectations in rivers, public spaces and roads, as shown in the photos.

In relation to the need mentioned above, it is necessary to procure from the organizations and institutions related with this area, to carry out exhaustive studies, to determine the specific solutions for each problematic one, and not to incur in the planning and in The execution of huge projects that, although they can fulfil the functions for which they are formulated, can generate negative situations, both in the urban and rural environment, because, among other things, not to consider the state in which the physical space is located That has been studied (land use).

In various regions of the world, the development of infrastructure has had a very considerable cost in the environment, among them are the deforestation, the variation of the watersheds, the destruction of ecosystems, among others. In this case, the images correspond to the satellite view and the panorama of the construction of a hydroelectric complex in one of the rivers of the Amazon in Brazil, where the alteration all the components of this ecosystem, has become present.

On the other hand, it should be pointed out that in order to obtain good results as indicated in the preceding paragraphs, it is vital that each of the states assess the need to carry out sufficient investments in this regard, since through alliances of private corporations and mixed consortiums (public and private). However, it is indispensable to have an efficient control system that is capable of determining the existence of sources of corruption that can indisputably cause damage to the projects, such as non-compliance with delivery times and disrespect to the legal regulations corresponding to the physical requirements (composition of structures and facilities), as well as to the environment in which they develop, as it is in different ecosystems rich in natural species, which in many cases, are unique in a region.

The control in the development and execution of the hydraulic projects are essential for an excellent obtaining of excellent results and to avoid the origin of problems both to the environment and to a population nucleus. Note in the images, as works of aqueduct and unfinished sewage generate damage to the inhabitants in two South American cities.

Finally, at the rate of all that has been reflected in this article, it can be concluded that the hydraulic works are extremely vital to consolidate the integral development in a certain area worldwide because, as indicated , not only are they planned for domestic and industrial purposes, but as the need and technology advance, they are part of large-scale structures used for various purposes. That is why it requires further research in the area, in order to continue contributing to the healthy innovation and planning of this type of works, respecting each of the legal bases that have been created for regulatory and protective purposes.
