Pressure irrigation, which includes sprinkler and local irrigation, is a modern method for the optimal use of water resources for sustainable agriculture. In general, the following goals can be considered for it
The presence of surface and groundwater in the bed of structures has always been an unpleasant and worrying issue. Water is the source of life and its existence is essential for human beings. On the other hand, its excess will cause a wet state in urban infrastructure and agricultural lands and will cause damage. In these cases, the use of drainage is recommended as a safe way to remove excess water from the site. Drainage systems are controlled paths for water flow that reduce water leakage pressure in earthen dams, slopes, retaining structures, roads, embankments located on the surface of slopes and tunnels, and overflows and construction pits. Some drainage systems are considered during the design of the structure, while others are used after the construction of the structure and as a restorative method. In general, drainage system is critical in two places:
Among the factors of land drainage can be mentioned the following:
The following are the most important drainage targets
Dam construction industry is one of the most important and strategic industries. Population growth, rising health, limited freshwater resources, over-abstraction of groundwater and interference of saline and freshwater fronts are the most important necessary factors for the construction of dams. The Iranian people have been among the best experts in the water industry since the past, and dam construction began in a modern and large-scale manner in Iran about three decades ago.
.Nowadays, water supply to agricultural lands, industrial estates, factories and various urban areas is one of the requirements of engineering projects. Different types of ducts for water transfer are suggested by consulting engineers. Topography, available height, type of structure, implementation methods, economic factors and water quality are the main considerations for selecting suitable ducts for water transfer system. The channels are one of the most important structures in water transmission systems that are used for agricultural irrigation, urban water supply, hydropower consumption, land drainage, and sewage disposal. In the upstream of the transmission channels, a water supply source such as a reservoir or diversion dam or pumping station is installed. Correct and appropriate design of the canal in terms of location, route characteristics as well as hydraulic characteristics leads to proper and effective water transfer for the defined needs and ultimately achieves the desired goals. DOA consulting engineers are able to design various types of water transfer ducts due to their brilliant records and experienced personnel.
One of the most important human concerns has been the transfer of water to different areas. For this purpose, humans have used water transmission lines in different ways. In fact, water transmission lines are facilities and equipment that are designed and implemented to supply water, transfer and distribute water from the existing source to the place of consumption. This transfer can be done in various ways, including water transfer tunnels, open canals, and finally special water supply pipes to supply water to cities, villages and industrial towns. Before designing and implementing the pipeline, the most important factor in achieving the mentioned goals is to determine the exact route of the pipeline. Thus, first all the effective parameters in determining the route including pipeline length, topography, soil type, fault lines, intersections with rivers and swamps, intersections with roads and railways, infrastructure, population centers, settlements, environmentally sensitive areas , important places of agriculture, land-cover and land-use are extracted from basic maps and through field operations. DOA Consulting engineer is known as one of the leaders of water transmission lines with the design of 600 km of water transmission line with pipes.
DOA Engineering Company, as one of the effective companies in the field of water engineering, offers high quality engineering services to employers. The ideal of the company and its human resources is to play a lasting role in the water industry and achieve sustainable development.
