Traffic management and drainage system are two vital issues for any metropolitan city. Like other big cities, Beirut is also facing problems due to lack of traffic management and poor drainage system.

The main objective of the innovation is to model the interdisciplinary issues of storm water and its effect on the traffic of Beirut.

The specific objectives are: (1) to calibrate and validate urban hydraulic and traffic micro-simulation models and (2) to model storm water and traffic for future conditions.

Due to poor management of drainage and traffic, a rainfall event becomes a tragedy. This often occurs when there is a poor planning of the region. This issue needs to be addressed accordingly, especially in the urban environment, since urbanized areas have to be the pivotal focus of planning development and management as mentioned in our innovation-based criteria.

iDrone-based Innovation of Hydro-Mathematical Model
for Resolving Flooding & Stormwater Traffic Congestion on Roads of Lebanon
Comprehensive Case study for all Roads, under-bridges and floods on plain areas
(Typical Case Study for varios regions of Lebanon)

Hydro-mathematical Case Study Model for Resolving Traffic Congestion on Tunnel, Bridge-Underpass and Overpass As flood Stirs Uproar in Lebanon - The scenes were a national embarrassment for a country that once prided itself on its sparkling Mediterranean coastline

Study Area
Typical Areas like under bridges
and tunnels at both sides.

  • Section of an arterial road has high volume peak in the morning (7:30 am to 9:00 am) on both ways.

  • Length under study is a road stretch of 100m-300m in tunnel or under bridge.

  • Effect of rainfall on traffic, the trend and occurrence of rainfall are a prerequisite.

  • The variation in the trend and periodicity of rainfall.

  • Rain had a negative impact on the operating speed and road capacity.

  • Rain had greater influence as compared to all other factors which tend to decrease the traffic.

Outcomes & Recommendations

  • AK&K developed a GIS-based urban flood inundation model. The model had two parts: storm runoff model, and an inundation model.

  • Cumulative surface runoff, which was an output of the storm– runoff model, served as input to the inundation model. The adapted flat-water model was found to be a useful alternative to a physical-based dynamic model considering computation requirements.
