Technical Facilties

NRI endeavors to use the most modern techniques and technologies to accomplish its objectives. It can now claim unprecedented capabilities and diversified know-how; this is manifested in many ways summarized as:


1- Hydrographic survey

The Institute has a very powerful survey system for hydrographic and land surveys in global and local coordinates. Modern survey techniques using DGPS in conjunction with Dual frequency single and multi Beam echo-sounder.  This system is supported with one of the most advanced data logging software. The Institute uses Hypack, TERRA model and Qinsy systems. The Field equipment of data acquisition is compatible and connected with the used system for Map production.

Multi Beam Echousonder.

- Acoustic Doppler Current Profiler.

- Integrated Hydrographic Survey System (DGPS).

- Total station.

- bed Sediment and water samplers.

 

The institute operates a fleet of boats and supporting facilities (softweres,  and radios, Thoria phone…..etc).



2- Sediment Laboratory

 The Institute operates sediment laboratory available for analysis of bed and suspended sediment samples. Dry and wet analysis for determining grain size distribution for the samples and sediment finer than 62 µm.


3- Water quality laboratory

The institute operates a modern water quality laboratory to handle and prepare the field requirements  for monitoring the quality of the Nile and Lake Nasser water as well as all point sources of pollution (industrial agriculture, municipal; etc.). in addition the institute own in situ lab to real time anlysis of different water quality components. The rest of analysis took place at the CEIECOM.



4- Technical Library

The institute maintains a small, specialized library containing more than 1500 texts related to river engineering, sedimentation, water resources development, computer sciences, water quality, project management, Geographic Positioning System (GPS), Geographic Information System (GIS), hydrographic survey, and the Nile volumes, and as well, it subscribes to scores of scientific journals and periodicals. The available references range from a recent copy of the Encyclopedia Brittanica, to a complete set of the

Nile

volumes, to both historic and current texts on all aspects of hydraulic and hydrologic engineering. The Institute owns a complete set of Audio visual equipment as well photography workshop. 

 

5- DDS System (Data Dissemination System)

DDS system is freely provided to NRI through TIGER project, this system is used to retrieve the Envitsat products Such as MERIS, ASAR and AATSR images through broadcast satellite signals. Data products are created by the Payload Data Handling Station and transmitted by the Up-link site through a satellite system to the customers. At the customer premises, a DDS receiver (BSR200-DDS) decodes stores and then forwards the products to a local storage server.


6- Programs and software

  • HYPACK

HYPACK is windows-based software for the hydrographic and dredging industry. It provides hydrographic surveyors with all of the tools needed to design their survey, collect data, process it, reduce it, and generate final products.

Different modules include:

-  Single Beam and Side Scan Survey Module.

-  Multi-beam Survey Module.

I have the ability to use each of two modules in hydrographic survey.


  •  Beam- VISAT

BEAM is an open-source toolbox and development platform for viewing, analyzing and processing of remote sensing raster data. Originally developed to facilitate the utilization of image data from Envisat's optical instruments, BEAM now supports a growing number of other raster data formats such as GeoTIFF and NetCDF as well as data formats of other EO sensors such as MODIS, AVHRR, AVNIR, PRISM and CHRIS/Proba. Various data and algorithms are supported by dedicated extension plug-ins.

 

  • ILWIS

ILWIS is open-sources software used for analyzing remote sensing images.


  • MD_SWMS (iRIC)

Multi-Dimensional Surface-Water Modeling System (MD_SWMS) is a pre- and post-processing application for computational models of surface-water hydraulics. The GUI tool of the MD_SWMS is a sophisticated one-, two-, and three-dimensional interactive graphical user interface that is used to design and visualize all aspects of data commonly associated with computational surface-water applications.This modeling system includes the following models such as FaSTMECH and SToRM.

  • Hec-Ras

A one dimensional numerical model can be used for surface water. The program is window environment and easy to use. The water surface profile is calculated by the standard step method. Different scenarios of steady and unsteady flow can be modeled. Calibration of the water surface can be carried out by adjusting manning roughness to match real situation. The program has four modules:

  1. Steady flow
  2. Unsteady flow
  3. Sediment transport
  4. Water quality

Each module can predict and calculate parameters in the longitudinal direction.

 

  • SMS (Water Surface Modeling System)

Two dimensional mathematical model is used for surface water. The program can be applied for steady and unsteady flow conditions for predicting sediment transport in the direction of main flow and in the perpendicular direction. Several applications can be modeled by sms such as local scour around bridge piers, spur dikes and abutment…the outputs of the programs such as flow velocities in two directions and water levels can be used to conduct further analysis.


  • Mike 11

This program is developed by Danish Hydraulic Institute (DHI). The program is a one dimensional model and designated for surface water and capable on calculating the water surface profile, watershed modeling, and water quality modeling.

 

  • Mike 21

This program is a two dimensional model developed by DHI for surface water. The model is based on the finite volume method to approximate the main equations of hydraulics. The model is a coupled model and predict sediment transport in river and water quality as well.
