The main features of the project are:

  • Field work to determine:
    • Topographic survey, based on photogrammetric restitution of flight drone of 10 km of channel with an average width of 300 m and mooring to the geodetic network with complementary triangulation by means of total station.
  • Processing of the national UDAR flight of 2×2 m resolution.
  • Geotechnical campaign for the characterization of the terrain at 20 points along the channel at 3 different depths.
  • Conducting socio-economic surveys.
  • Carrying out a study of fluvial hydraulics:
    • Pseudo-distributed hydrological model in Hec-HMS for the Jiboa River basin upstream of the stretch known as El Achiotal, with a total size of 568 km2.
    • Modelling of river dynamics.
    • Prediction of future migration of the channel.
    • 2D hydraulic modeling in ISER.
    • GIS processing of the results of the 2D hydraulic model
    • Calculation of monthly contributions according to the Témez model.
    • Calculation of sediment transport according to the revised universal soil loss equation (RUSLE).
    • Evaluation of 2D sediment transport in each sub-section using the MIKE 21C model.
  • Development of social and environmental zoning maps setting out the feasibility of quarrying.
  • Legal analysis of the existing regulations and proposal to update the Environmental Law to regulate the sustainable extraction of stones – defining sustainability based on a specific zoning criterion as established in this consultancy – and to allow municipalities to carry out inspection and monitoring tasks that are regulated by municipal ordinances.
