 Irriworks is at your disposal to provide you with highlevel design services and advanced tools for irrigation systems and networks. Our team of hydraulic engineers and highly specialized irrigation professionals can provide you with all the technical support and information necessary to design or verify any system. 
Thanks to our expertise and to IrriPro software, we can know with precision the behaviour of the system before it is installed. In Irriworks we deal with green space service facilities in urban and extraurban areas, from vertical gardens to multilevel structures. After the phase of acquisition of the plans, of the architectural plans and of the already planned systems, we analyze different usage scenarios in order to identify the solution that presents the best performances. 

 Based on the information received from the client, our team of engineers develops the project according to the required criteria and proposes various briefings for the presentation of the project to share the intermediate results and to plan possible corrections or changes to be made. Our engineering approach allows us to offer a consulting service for plants to be designed in complex conditions and structures, achieving results of maximum efficiency and functionality. 
The goal of the service is the best possible customer satisfaction by providing the required documents, facilitating the understanding of the project and providing any support during the construction of the plant, in Italy and abroad.
RIYADH METROPOLITAN  SNAM TARSIA PLANT 
As an alternative to consulting, we propose the purchase of IrriPro as a design tool, recommended for all technicians who frequently face the irrigation system project.
Today IrriPro is the most popular software on the market because it represents the easiest program to use and the most reliable support for the technician who wants reliable and rapid results.
Irriworks software was used (in collaboration with the Agrarian Faculty of the University of Palermo, measure 3.13 of POR Sicily PIT7) for an irrigation system at the farm called "Licata" in the City of Bompensiere (CL). The plant is costitued by 180 pressure compensated drip emitters, is located on a plot of about 0.6 ha, with slopes from 10% to 18%, and is planted with olive trees.
There are some differences between estimated values (simulated with the IrriPro software) and afield measured ones: no more than 9% for pressure and 6% for the discharge. The error is mainly due to constructive aspect of the emitter during factory production.
Estimatedmeasured pressure chart
For the same reason, the uniformity coefficient was equal to 94%, as assessed by IrriPro, compared to 91% measured in the field.
In short, the software IrriPro simulated very well the conditions of operation of the network.

Costant Head losses  Calculated assuming Variables the flow rates of each part of pipe and the outgoing flow from each emitter (rigorous formulation of the equation of motion and continuity)  Calculated by taking the equivalent discharge transiting the entire length of the pipeline  30% of the total head losses  The evolution of pressure due to continuous losses, calculated as the equivalent discharge of service along the pipe, has a constant slope and differently by reality. The calculation of uniformity in this case is not reliable 
Local head losses  Considered using a rigorous formulation depending on the size of the emitter  Not considered or imposed as a constant proportion of the pressure  50% of the total head losses  The local head losses (due to the presence of emitters) include up to 50% of the total head losses 
Integral calculus of the system  Integral calculus of all processed laterals considering their mutual interaction between each element  Calculation on a single chosen lateral    The reliability calculation for a single lateral (the result is then extended to the whole system) depends on the choice of the lateral and the size of the system 
Temperature  Modifiable  Not modifiable  710% of the total pressures  Temperature affects the viscosity and density of water 
In this case, how extensive is the area where the designer must adjust the project to improve the conditions?  The overview is complete and, point by point, the designer knows where to intervene 
The longest because it can last from a few days to several months (In figure, a survey obtained after 3 months of work) depending on the size of the land and the required precision.
Once you have made the survey it will contain the planimetric information (such as shape and size of the sector) and altitude (the altitude at each point detected). Knowing the elevations you can calculate the slopes of the pipeline: at present no instrument except IrriPro, manages to consider the slopes for each part of pipe and the elevations of each emitter. The only information used by thirdparty software is slope value, which is considered constant for the entire length of the pipeline: this produces gross miscalculation and incorrect project. IrriPro, by contrast, allows you to take into account in hydraulic calculation all planimetric and elevation data that describe the terrain: each part of pipe will present the right slope, and each emitter will be placed at the correct altitude. Furthermore, in order to make it easier and fast as possible the acquisition of 3D terrain model, the software offers three different ways to enter data:
The surveying service of Google Earth/Maps, included in IrriPro software, is also available online at this link.
Further on, are described in more detail, the technology and the method behind the survey through Google Maps.
Thanks also to the revolutionary technology for survey from the Google Maps/Earth online service, available within the program, you can perform the topographic survey of the area where you implement the system without moving from your PC: You will get 3D model of the land: this feature is used to perform the topographic planoaltimetric survey of the area where will be designed and built the irrigation system.
Through this console you can make a topographical survey of land simply by identifying the area to be detected . The user can use this feature to:
 
IrriPro matter the satellite imagery and GIS data (DEM as ASC file) to calculate coordinates and dimensions of each object that will be included in the workspace of the software. The DEM (Digital Elevation Model) product is a raster data model, in the case of 2500 detected points, it consists of a matrix square mesh of 50 rows and 50 columns. The characteristics listed in the planoaltimetric DEM are georeferenced to the UTMWGS84.  
Knowing the planoaltimetric trend of the land, slopes and elevations will be allocated to the elements (such as pipelines and regulators) according to their position. Throughout the work area, the elevations (listed next to the mouse cursor) were obtained through a SPLINEStype interpolation procedure of DEM data. Intercepting points of equal altitude with lines you get the various contour lines. 
RELIABILITY OF THE GIS DATA IN GOOGLE MAPS/EARTH
From studies carried out by the company Irriworks, it appears that the quality of data extracted from GIS service Google Maps is comparable to the same level of a technical mapping on a scale of 1:10,000 and then sufficiently reliable for the design of irrigation systems. In addition, you should not underestimate the great difference of time, resources and equipment to be used for the construction of a detailed survey: For the areas under study, this has required a time of 3 months compared to the few minutes used to extract data through the GE service, whereby it is possible in real time and in the areas where you do not have a traditional cartographic support, to obtain a reliable representation of the difference plot.

IRRIPRO 
The software for the design of irrigation systems IrriPro thanks to its "heart of calculation" that makes use of the fundamental equations of hydraulics, is able to analyze the irrigation networks with a new and rigorous method. The formulation of the classical equations of hydraulics used in the algorithm excludes forms of empiricism and simplifying assumptions that depart from the expected final result. The software, in fact uses a calculation algorithm that solves the equations that govern the motion of the currents in pressure (equations of continuity and equation of motion) starting from the boundary hydraulic and geometric conditions, from the plano and altimetric distribution of the irrigation network, as well as hydraulic and geometric characteristics of the pipes and installed emitters.
The designer is supported in the search for changes to be made to improve the design, as it features tools for analysis and diagnostics needed to assess the consequences of each design choice.
]]>When designing an irrigation system many variables come into play such as the size and ground slope to be irrigated, and the characteristics of the emitters used. All of these factors and design criteria have important consequences in the behavior of the system in which the only drawing can not answer. It is therefore necessary to use a tool capable of dealing with the hard task of a real design.
