Urbano Hydra

Urbano offers the possibility of importing raster and vector data from a local disk and placing them in the correct geographical location. It is possible to import many data and display them as needed and for vector data it is also possible to filter layers upon import.

Supported types of DTM include Civil 3D, 3D Face and Terraform – Urbano module for creating DTM.

DTM can be created in several different ways – by directly importing points from a text file, SHP, or database, or by converting CAD elements such as points and lines with elevations, 3D polylines or texts and blocks. Urbano Terraform also offers a variety of tools for working with point clouds – loading, viewing and importing using a variety of location and elevation filters.

During the design phase, terrain heights can be set from the above-mentioned DTM surfaces and by direct input, linear interpolation or import from an external source.

Urbano enables the conversion of CAD elements (lines, 2D or 3D polylines) into the Urbano system. In addition to the network itself, Urbano can also convert data written in CAD texts and block attributes such as pipe diameters or terrain heights.

In this way, it is possible to convert old pipe network projects drawn with plain CAD elements into intelligent Urbano objects on which it is possible to use all standard Urbano commands.

The system in plan can be shown in different styles. Sections can be shown as lines and nodes as blocks or geometric shapes. In addition to this basic display mode, sections and nodes can also be shown in 2D view with actual pipe and manhole dimensions or in 3D. All visible and invisible parts of pipes and manholes (outer and inner edges, axis, wall…) can be shown in different colors, hatches, line types and thicknesses. Node blocks can be edited, or you can use your own, user-defined blocks.

Different plan styles can be applied to different systems or parts of a system. This is an ideal way to visually separate system parts according to the type of system (e.g., gravity, pressure, vacuum sewage), type of pipeline (main, distribution, supply…) or construction phase (built, designed, out of use…).

Labels are based on configurations. There are several types of labels – section labels, nodes, stations, branches and arrays, cross sections, angles, etc. All labels are automatically updated on any change in configuration or model. Labels can be moved and rotated interactively. In addition to the interactive mode, there is also a tool for automatic label reposition. This tool can automatically move all labels that collide with topology or another label in just a few seconds.

The program offers several standard label configurations with predefined data. Each configuration can be edited and copied. Also, it is possible and very easy to create your own label configuration using the provided templates.

Longitudinal sections are based on configurations which allows them to be drawn and edited quickly and flexibly. Longitudinal sections can be drawn using any selection of topological elements (array, branch, from node to node…), one by one or more longitudinal sections at once.

The same topological elements can be displayed simultaneously in several longitudinal sections, e.g., drawn with a different configuration (different data, language, standard, scale…) and it is also possible to replace the current configuration with another.

Editing the configuration of the longitudinal section is extremely simple and user-friendly. Each component (graphic or tabular – data) can be interactively selected in the longitudinal section and all details can be set for it such as colors, hatches, sizes, texts, line types, decorative blocks, data table contents…

Longitudinal sections can be drawn in various scales and the drawn profiles can be automatically prepared for plotting on papers of the desired dimensions.

Urbano catalog offers several standard types of trenches (rectangular, trapezoidal, with or without steps, with or without formwork). Also, there is a catalog of top layers that can consist of any number of layers of different thickness. Trenches and top layers can be assigned to topological elements using various topological selections, from node to node or from station to station.

For standard trenches, it is possible to prepare cross section configurations that contain all graphic components such as colors, hatches, dimensions and data. Cross sections can be drawn for any part of the network by interactively selecting the station in plan or in longitudinal sections and automatically at characteristic points of the network or on a constant distance.

In addition to standard trench types, it is possible to define a parametric trench of arbitrary shape. This parametric trench can also be used as a multi-pipe trench.

For given trenches, it is possible to calculate total excavation volumes, excavation volumes according to depth zones, volumes of bedding and all backfill layers and formwork area.

It is possible to make detailed node assembly schemes based on the catalog of assembly elements (fittings and appurtenances). A catalog of parametric and block elements that can be edited is available, or you can make your own. All pieces and schemes are drawn interactively and to scale.

In addition to detailed schemes, Urbano also has a function for automatic drawing of node schematic symbols. These schemes are drawn based on a set of customizable rules and a catalog of symbols. Symbols and schemes are not to scale and are used to represent the nodes symbolically. It is possible to draw all the node schemes in just a few seconds.

In both cases, each scheme has a table with the names and quantities of the elements used and it is easy to get a list of all the elements in the whole project in the form of a CAD table or Excel report.

Drawing functions allow direct input of data on terrain heights, invert elevations / depths, slopes and pipes. House connections can also be automatically labeled when drawing.

In addition to intersections between Urbano pipe systems, it is possible to analyze intersections with CAD elements (lines, 2D or 3D polylines) that can represent different pipe or cable infrastructures such as gas pipelines, power, or telecommunication cables, etc.

Pipe optimization allows automatic calculation of optimal pipe diameters based on pre-defined water demands and target velocities in the pipes. For different parts of the network, it is possible to set different target velocities and different pipe diameter ranges to get the best possible results. The results obtained can be adopted or modified by post-processing tools. The calculation is based on the method of genetic algorithms.

Urbano Hydra uses EPANET for hydraulic calculations. The EPANET code is built into Urbano so it is not necessary to have EPANET installed on the computer. Based on pre-defined network elements and pipe diameters, set parameters and water demands, Urbano Hydra can perform a single period (snapshot) hydraulic calculation or a complete time simulation over a certain period of time. By using rules, it is possible to control the operation of network elements over time. All results (flows, velocities, headlosses, head elevations and pressures) can be analyzed tabularly through data previews or graphically through graphs, longitudinal sections and thematic maps.
