Uzbekistan - Flood Modeling and River Rehabilitation Planning, Design and Consultancy Services in Daryo Bo Business City Section of Chirchik River

Brief Description of the Project:

The main scope of the project : Flood protection and river rehabilitation for the 16 km section of the Chirchik River that passes through Tashkent City. Also, the structural design of pedestrian bridges, highway bridges, reno-mattress protection, rip-rap slope protection, gabion weirs and inflatable rubber dam.

Scope of Services :

• Plan and prepare hydrological and hydraulic modelling (1D and 2D) studies comprising of:  Data Collection and Analysis (TRMM 3-hourly data for hydrologic model, ALOS digital elevation data for watershed delineation, Statistical Tests for Best Fit Distribution,  NASA Earth Exchange Downscaled Climate Projections Data for climate change scenario, GCN250 global gridded curve numbers dataset, HEC-HMS models for Chirchik River and its tributaries), HEC-RAS 1D and 2D models. 

• Prepare the inception report that covers preliminary flood risk assessment and hydraulic design. Undertook Site visits, prepare info about past floods, define risk areas and prepare the related reports with regards design and implementation of the flood risk management measures.

• Prepare the flood early-warning system consisting of: Data collection, data processing, setting of warning level and relevant activities, evacuation plans, etc.

• Analyze the Renewable energy potential and provided recommendations and solutions. Inflow calculations for the projects area, energy optimization studies, selection of turbine type, design discharge and installed capacity.

• Plan and prepare the Design of structural measures for Q500 flood risk management. Detailed design of flood walls, reno-mattress protection, rip-rap slope protection, gabion weirs, replacing existing weirs with inflatable rubber-dams.

• Structural design of pedestrian and highway bridges.
