Collecting and Controlling of Runoff in Semnan County

About Project

Given that considerable quantity of runoff flows after the rainfall in urban areas, in most streets of Semnan city, it causes many problems and ultimately disturbs commuting and intensifies traffic. Then, controlling of runoff is obviously necessary and it is required to precede a comprehensive plan to remedy this issue. Municipality of Semnan to eliminate this problem and find structural solution has contracted with Asarab to study and investigate waterways pattern and status in the city to modify the hydraulic connections among canals and waterways.

Actual services:

• Presentation of physiographical reports of urban and non-urban watersheds in the study area
• Meteorological studies and calculation of climatic parameters: rainfall, temperature, evaporation, relative humidity and determination of climatic features
• Hydrological and hydrogeological studies to explore data for simulating urban flood using Storm Water Management Model 5 (SWMM5)
• Proposing restoration, reconstruction and construction plan of new collectors using the results of modelling
• Investigating the status of the streams and solutions for controlling the surface water
• Investigation of waterways and possible alternatives for construction of runoff collection network
• Study of the existing status of urban and suburban waterways
• Researching to find new methods decreasing water flow in urban areas
• Selecting wastewater collection system and solutions for controlling run-off
• Designing of hydraulic sections of the ducts and streams according to the quality of ducts
• Preparing comprehensive maps and drawings for controlling and collection of run-offs
