Without knowing how it behaves hydraulically a network, at any point, how do you know which diameter of the pipeline to adopt or which and how many emitters you can feed? How can you say that a project is well done, not knowing if at any point is dispensed the right amount of water?
The proper project takes into account all the geometrical parameters, physical, topographical as well as the boundary conditions where the plant will be built and uses the most advanced engineering methodologies and mathematical formulas to analyze the quality of irrigation. The third-party software adopt simplified methods to calculate the flow and pressure: typically they design according to the criterion of constant speed in the pipe or strive for minimum cost economic.
In this way we obtain approximate results and the technician is unable to answer the questions: does the water reach all parts of the installation? Is the irrigation system working well? Can The plant guarantee me an acceptable quality for irrigation? Take for example a plant on an area of 0.
On following table it shows the consequences if it isn't considered any parameters in the calculation:. Processing 3D model of the ground for a variable slope, point by point, section by section, pipe by pipe. The error varies according to the order they are presented with the change of slope. 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. 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. Integral calculus of all processed laterals considering their mutual interaction between each element. 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.
In conclusion, the error committed not considering any or all of the components of the calculation may become significant. In other words, a simple calculation gives no guarantee to the success of a project.
The other software are able to calculate the hydraulic characteristics in few points on the network. IrriPro, however, allows the designer to know the continuous distribution not discrete of the values of pressure and discharge, and therefore know where and how far to correct to improve the project. For example, the thematic map of IrriPro, through different colors for different scales of flow rate and pressure, allows the designer to know how serious and extensive the negative condition is and fix all the points where the water supply is in deficit.
Other software IrriPro 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. More Articles The survey Irrigation softwares Why to design irrigation systems. Awards Thanks to IrriPro's innovative technology, which has achieved some international awards , it's now possible to calculate all the hydraulic parameters and design correctly and efficiently any kind of irrigation system.
Prev Next Why to design irrigation systems. Irrigation is the most i Irrigation softwares. In this page it will be dealt with irrigation design software and other tools to design irrigation systems.
Bill of Materials. Create a bill of materials for an entire design or any part of a design specified by you. Ability to create alternative combinations of designs to analyse and arrive at the most economical or practical solution. You can use our support forum to trouble shoot, download the latest patches and databases, or use our manuals and guides to learn new skills.
For example, to select the right irrigation equipment for irrigation, you need to specify your requirements to the software. You can specify irrigation requirements like section length, section slope, number of outlets, total, flow, etc.
By taking your requirements into account, the software will suggest you all the right pieces of equipment. Through some of these software, you can also estimate the right amount of water your crops will need in a period of time. To estimate water requirements, you need to enter data like location of your field, temperature, rain data of various months, etc. After the analysis of input values, the software will give you water usage results.
The estimation of water requirements also help you conserve the water resources. The good thing about most of these software is that they not only provide results in numerical form but also in visual forms graphs, charts, etc. Go through the list to know more about these software. CROPWAT is my favorite software because it lets you estimate the water requirements for your fields which is really importnat in irrigation. Plus, it helps you conserve the water resources.
You can use this software if you want to select the right set of irrigation equipments as per your requirements. It is an advanced irrigation design software through which you can calculate the water requirements for crops during and after the rainy season , calculate irrigation requirements according to the type of soil , and calculate climate and crop data.
Plus, it allows you to create a schedule for the irrigation according to different water supply and crop patterns. To perform all the essential calculations for irrigation, this software comes with various sections. It is one of the most comprehensive irrigation design software through which you can calculate various irrigation design parameters. A sample run was made with assumed data for different crops. For Apple crop with a spacing of 15ft x 15ft requires 1 hp pump with total head of For Banana crop with spacing of 10ft x 10ft requires 3 hp pump with total head of Per ha.
For Coconut crop with spacing of 20ft x 20ft requires 1 hp pump with total head of For Mango crop with spacing of 25ft x 25ft requires 1 hp pump with total head of For Pomegranate crop with spacing of 15ft x 15ft requires 1 hp pump with total head of For Orange crop with spacing of 18ft x 18ft requires 2 hp pump with total head of Drip or trickle, also called micro or localized irrigation is a pressurized system to irrigate the crops and orchards, consists of an extensive network of pipes usually of small diameters that deliver water directly to the soil near the plant.
The system usually possesses fertilizer injection system, supplying plants with needed nutrients. In drip irrigation, the objective is to provide each plant with a continuous readily available supply of soil moisture, which is sufficient to meet transpiration demands.
A filter is used to remove suspended materials, organic matter, sand and clay to reduce blockage of the emitters. Along with pumping station, control valves are installed to www. Hema Narayana Reddy, K. Ramana provide required pressure heads to the system. The system contains emitters, laterals, manifold and mainline, which supplies water from the source to plant root zone. The mainline delivers water to manifold and manifold delivers water to laterals.
The emitters, which are attached to laterals, distribute water to plant root zones. Laterals are normally made of polyethylene PE with diameters 12 to 20 mm in range, providing better flushing, easy installation and maintenance characteristics. Manifold and mainline are either in medium density polyethylene PE or rigid PVC with diameters 20 to mm in range. Emitters are of many kinds, such as, orifices, nozzles, porous pipes, microtubes, etc.
