Restraint and Management Program for the Ayalon Basin Runoff

The Restraint and Management Program for the Ayalon River Runoff is a large-scale project to construct a fourth railroad track along Highway 20 from Tel Aviv University Station to the eastern part of the city, and third and fourth railroad tracks along Highway 1 from the Kibbutz Galuyot interchange to the city of Lod. The plans for the fourth railroad track along Highway 20 can be implemented only if the existing Ayalon River Channel (“the Channel”), which currently conveys the river water to the sea, is narrowed to make room for the railroad tracks. Narrowing of the Channel from 20 m to 10 m wide is expected to decrease its conveyance capacity from 400 cubic meters per second (m³/s) to 200 m³/s. 

 

This change necessitates planning of several integrate solutions to ensure that all Ayalon River flow is conveyed to the sea and to minimize flooding events. The basis of design for the current project will be changed to a 100-year average recurrence interval flood, with a projected flow rate of 660 m³/s. The planned detention reservoir in Ariel Sharon Park is intended to buffer this peak discharge, reducing peak flow to the sea from 660 m³/s to 400 m³/s.

 

The project’s aim is therefore to moderate tides runoff (floods) at the Ayalon basin in order to protect the transportation system including the Ayalon route fourth track, and southern neighborhoods of Tel Aviv. 

 

Ayalon's upriver

The upriver level comprises a vast area from Modi’in in the east to Or-Yehuda in the west. In this region, the objective is to restrain as much rainwater as possible by creating a number of reservoirs in a range of sizes and capacities throughout the region. 

 

Ayalon's downriver

The downriver area is composed of two main sites; the Ariel Sharon Park (ASP) and the agricultural lands of the Mikve Israel School 

These are designed as reservoir in necessity that will delay and pool the Ayalon River’s rainwater leftovers/flows excesses. ASP and Mikve Israel will retain their designated uses of recreation park and agriculture and will function as reservoirs only in emergencies. 

 

Ayalon's outfall

The outfall part’s objective is to convey water from the Ayalon River to the Mediterranean Sea in the event of overflow emergency. This could be executed by building a tunnel from the Ayalon channel to the Mediterranean Sea through a historically planned route in Yafo, or by any other mean deployed on the existing Ayalon channel. 

The proposed tunnel through Yafo will be laid in the form of a tube starting from the area of “Mikve Israel”. In collaboration with ‘Moria-Sekeley landscape & architecture’ we are offering an open channel as an urban route for pedestrian and bicycle and other recreational activities.
