Project Location:

The project is located in Ansab area in Muscat Governorate.

According to the TOR, the Scope of Work is detailed as follows:

According to the Terms of Reference, the Scope of Work is divided into three stages as follows:

Stage 1 –Hydrological Review, Topographic Study, Soil Investigation, Hydraulic Modeling

-       Inception stage including desk studies, review of existing information and initial site visits to determine additional information required

-       Topographic surveys of each site, including the immediate upstream and downstream areas is required to ensure the hydraulic models are based on reality.

-       Physical survey of all existing utilities, such as water supply and sewage networks, electricity and telecommunication cables, etc

-       Hydrologic analysis of the upstream catchments to determine flood volumes and peak discharge is considered in detail.

-       Hydraulic analysis of the water courses, including wadis and existing sub surface and surface drainage structures to locate areas where the conveyance capacities are exceeded

-       Evaluation of various flood protection measures and overflowing risks

-       Investigation Requirements including tender documents for geotechnical site investigations.

-       Soil investigations

-       Review of the hydraulic capacity of the existing drainage system

-       Assessment of flood protection provided by existing flood conveyance and protection measures
