Confluence of two rivers, longitudinal and cross axes with geodetic points and other elements of a plan view	Layout The Layout module is used for inserting and editing of geodetic points, topographic and other symbols as well as for the 3D terrain modeling and adding of dimension lines. In addition, various calculations and interpolations are provided.
Axes design in Aquaterra	Axes In the Axes module, the user defines the longitudinal axis of a river or a channel to be designed. The station can be defined and marked along the axis. At the selected stations, the user determines the positions of cross sections, defines river banks and other lines along the axis. The module contains several functions for defining and saving longitudinal and cross sections from the layout points or DTM, as well as transfer of points from sections into the 3D space.
Longitudinal secton with banks and proposed vertical alignment of the new channel	Longitudinal Sections In the Longitudinal Sections, channel bottom, left and right bank, and several water surfaces can be presented. In case of a new channel design, vertical alignment of channel bottom can be added graphically. The presentation of a longitudinal section consists of a graph and a table. A single longitudinal section can be broken into several frames. Several tools are available for drawing and inserting of geometric elements, dimension lines etc.
3D model of a derivation channel	Cross Sections The Cross Sections module is used to draw the existing cross sections that can either be obtained from a geodetic survey or generated from a 3D terrain model. If conveyance of the existing cross sections is not satisfactory, new cross sections can be designed over the existing terrain, consisting of multiple trapezoidal sections and other elements. There are special commands for calculation of volumes. Water surfaces can be added to cross sections for several computational plans. Banks can be edited as well as Manning coefficients that are later used in hydraulic computation. The module has several tools for drawing and inserting of geometric elements, dimension lines etc.
An example of a channel element in Aqauterra	HEC-RAS Interface HEC-RAS interface is intended for communication with HEC-RAS, a widely used program for hydraulic computation of river systems. Based on the stations, geometry of cross sections, channel banks and Manning coefficient data, the interface prepares the HEC-RAS geometric input file. After the user completes the input data with flow and boundary conditions and carries out the desired computations, the resulting water levels can be translated back to Aquaterra. They can be shown in cross sections, longitudinal sections and layout.
Cross sections with bed and bank protection measures	MIKE 11 Interface MIKE11 interface is provided for communication with MIKE11, a more advanced hydraulic computation program. The interface exports the geometric data (stations and geometry of the cross sections, channel banks and levees) from Aquaterra to MIKE11 cross section file. In MIKE11, the user specifies the hydraulic parameters and carries out the computation. The interface also reads the MIKE11 result files and imports the following data back to Aquaterra: water levels, cross sections, longitudinal section, bank and levee positions. This allows fast and simple transfer of the MIKE11 results to Aquaterra cross sections, longitudinal sections and layout, even in the cases where input data has not been prepared with Aquaterra.
	MIKE 21 Interface MIKE 21 Interface connects AutoCAD Civil 3D with the most widely used 2D hydrodynamic computation program MIKE 21. The interface creates a MIKE 21 bathymetry file. Bathimetry is based on a rectangular grid that can be easily created with the interface both by specifying parameters in the dialog box and/or interactively in the drawing. Editing of the grid is also simple and efficient. One or more AutoCAD Civil 3D surfaces can be used for bathymetry, e.g. one representing the existing ground and several alternative detention basins. The interface also imports the results of MIKE 21 computation (non-utm dfs2 format only). Both vector field (velocity or flow) and a surface can be plotted. Surfaces can be further used to plot maps of flood depth, flow magnitude, etc.
