With over 130 years of experience and understanding in hydraulic engineering and river ecosystems we are able to better balance between the demands of our societies and environmental equilibrium
Infrastructure facilities located near to large bodies of water may be exposed to flooding. A failure to take timely measures to protect these exposed areas can result in severe economic impacts and danger to human lives. The choice developers face is whether to implement protection methods for such areas in advance or to address problems as they arise.
Flood basins below the level of spring tides or rainfall flood are exposed to flooding and shore erosion.
Developers and private housebuilders involved in constructing facilities near large expanses of water are not always able to correctly assess the potential threat of flooding which may not only lead to huge economic losses, but also threaten human lives.
To reduce these risks, hydraulic engineers and water authorities should take special protective and preventive measures, including flood forestalling and forecasting.
First, developers should make sure that the area concerned falls outside water protection zones and the list of protected shoreline belts. Then it is important to study engineering and hydro-meteorological survey data for the body of water or comparable bodies.
Specific measures for flood protection include the following options:
- Construction of flood-control dams. This measure blocks the passage of flood water to the place where an infrastructure facility is located
- Monitoring of the source of flooding. These measures allow for the adjustment of the water level directly at the source and include damming and building of other structures to control flooding outside the river bed
Our technical solutions can help in the construction of all the structures described above.
Engineering protection of land against floods involves the construction of a protective dam and the use of anti-erosion measures on the bank slopes. We can implement a number of effective options to reinforce flood-control dams and control erosion using the following solutions:
- Gravity retaining walls
- Slope protection with Reno Mattresses
- Terramesh® soil reinforcement structures.
Gravity retaining walls and Reno Mattresses are typical solutions to control erosion of bank slopes or to be used during construction of roads in floodable areas.
Our Terramesh® technology for embankment reinforcement can assist in the protection of banks from the action of waves as well as stabilizing the soil. The advantage is that the units can be naturally integrated into the surrounding environment over time.
Facilities to control the source of floods
The high velocity of water flowing down spillways of large and high dams requires careful consideration of the hydraulic erosion protection required; abrasion effects exerted by flood waters and river sediments are particular issues to be overcome. However, side or leading walls may be protected with gabions along the tail water where the flow velocity does not exceed 7 m/s. This decision is economically sound because local stone can be used as a filler material and the installation of gabions requires no heavy equipment.
Due to more suitable hydraulic conditions, technical solutions for flood-control structures outside of the river bed offer greater advantages. Our technologies are an ideal fit for the protection of spillways and catchment basin slopes during floods.
Gabions and Reno Mattresses® are cost effective solutions for the construction of spillways and can be used to create robust downstream slopes. Erosion-control mats MacMat® and MacMat® R are a proven means of slope protection.
Over 22 years of activity in Russia and the Commonwealth of Independent States (CIS), a number of large projects for flood and erosion protection were implemented using our technologies, such as:
- Dam reinforcement on the right bank of the Iren River, Perm Krai
- Slope reinforcement along the Khanty-Mansiysk — Nyagan highway
- Construction of the Tyumen — Khanty-Mansiysk highway, 640–710 km
- Diverging wall on the Tom River, Tomsk
- Bank protection on the Kugart River, Kyrgyzstan
Our hydroengineering solutions have proven to be efficient for over 130 years, since the erection of the first gabion wall in 1894 to protect the citizens of Bologna from flooding from the Reno River in Italy. This laid the foundation for our activities and we have since developed a variety of cost-effective solutions to suit a variety of hydraulic erosion problems.
