CONSULTANCY FOR EARLY FLOOD WARNING SYSTEM INCLUDING INUNDATION
FORECAST IN GANGA BASIN

 Date: 27.12.2019

No.:  NHP/2020/RDC-1/01

Expressions of Interest (EOI)

The Government of India has applied for a loan from the World Bank under the National Hydrology Project (NHP) and intends to apply part of the loan proceeds to make payments under the contract for Early Flood Warning System including Inundation Forecast in Ganga Basin.

NHP is countrywide project, with 49 Implementing agencies (IAs) including eight central agencies, 39 state-UT level agencies and two river basin organizations (RBO). The National Hydrology Project (NHP) is proposed to be an eight-year project starting from November, 2016. One of the studies under NHP is Early Flood Warning System including Inundation Forecast in Ganga Basin. The broad objective is to develop an Early Flood Warning system including inundation forecast and its integration with WRIS/e-SWIS with customized GIS tool for real time dissemination of forecast, inundation forecast, and inundation maps library including development of dashboard for query-based generation of flood warning/flood inundation maps for all stakeholders. 

The Project Development Objective of the National Hydrology Project is proposed “to improve the extent, quality, and accessibility of water resources information and to strengthen the capacity of targeted water resources management institutions in India”.

The study in the initial phase is presently for Ganga Basin having total catchment area of 1063100 sq.km, out of which 861000 sq.km are in India. Subsequently under the project similar studies shall be conducted for other major basins. Study area lies in the States of Chhattisgarh, Haryana, Rajasthan, Himachal Pradesh, Madhya Pradesh, Bihar, Uttar Pradesh, West Bengal, Jharkhand, Uttarakhand, and UT Delhi of India, who are Implementing Agencies in NHP and may use the resulting systems to capture, validate, store and disseminate Early Flood Warning in their States.

OBJECTIVES OF THE CONSULTANCY:

The broad objective of the Consultancy is to develop an Early Flood Warning system including inundation forecast and its integration with WRIS/e-SWIS with customized GIS tool for real time dissemination of forecast, inundation forecast, and inundation maps library including development of dashboard for query-based generation of flood warning/flood inundation maps for all stakeholders. 

The broad objectives of the study are as below:

1. Review and verify the currently used hydro-meteorological data. Correct, validate and process the required hydro-meteorological data of entire basin for the stations selected by CWC. Suggest alternative data if required.
2. Carry out river cross-section surveys for up to 500 selected locations in the river basin. The exact locations will be decided in close cooperation with CWC.  Process satellite images and Digital Elevation Model (DEM) to integrate the results of cross sections surveys with the DEM provided by CWC so as to calibrate and verify the previously developed 1-D flood forecasting model, or to calibrate another 1-D model chosen by the Consultant.
3. Conduct frequency analyses of historic floods and suggest a methodology to assess design hydrographs with desired return flow periods (2, 5, 10, 25, 50, 100, 200 and 500 years) for selected strategic locations in the basin that are of importance for flood management.   The frequency analysis will be done at all H.O stations with discharge measurement.  The Consultant may be requested to assess the effects of regulation on some of the stations and their peak flows, and correct the peak flows for the effects of regulation prior to conducting frequency analyses.
4. Develop a 2D or1D-2D coupled model as well as inundation forecasting for the basin area, for which DEM will be provided by the Client.

For the purpose of the current consultancy assignments, real time flood forecasting may be interpreted as issuing flood/inundation forecast for 1. Selected areas on real time basis 2. Other location based on the library of historical floods and / or model solutions that have the best match with the current rainfall and water level conditions, as well as the forecasted weather conditions. (A) Real time inundation forecast using 1D-2D coupled model will be carried out in few pockets of areas of strategic importance in consultation                             with respective CWC field offices/State government (Run at least once or twice a day. (B) Create an inundation map library for various return periods (2, 5, 10, 25, 50, 100, 200 and 500 years) of rainfall /flood events based on the results of simulation runs that relied on calibrated hydrodynamic model runs for different scenarios. Frequency analyses based Inundation    map libraries are to be prepared for all HO sites with discharge measurements.

5. Automate the whole process such that it includes the development of a dashboard - an interface routine that will receive required input data for modelling from the India-WRIS/e-SWIS web site, download all rainfall forecasts, satellite data, and real-time monitoring data, run the model at predefined frequency in consultation with the CWC, and upload the model results to the India-WRIS web site integrating all relevant GIS features in consultation with the Client.  Develop a mobile app for the dissemination of forecasted flood inundation areas including SMS alerts to relevant stakeholders/users with the inclusion of GIS layers like railways, roads, etc. made available by the Client.

6. Provide training and capacity building

7. Provide technical support, trouble shooting, maintenance and updating of models.

SCOPE OF THE CONSULTANCY:

The Broad scope of the study will consist but not limited to the following in brief as under. The final Terms of Reference and the scope of the study would be issued along with the Request for Proposals.

The Scope of the Consultancy is broadly divided in two phases as follows:

DURATION:

Total schedule time for completion of the consultancy services for ‘Early Flood Warning System Including Inundation Forecast in Ganga Basin’ shall be 24 months followed by Operation & Maintenance and upgradation period of 5 years.

IMPLEMENTATION ARRANGEMENT

The Project Implementation plan of the Consultancy is broadly divided into two phases as mentioned in Scope of the Consultancy.

Director, RDC-1 Directorate, Central Water Commission is purchaser and Director, FCA-2 is the Project Manager for this project. The Central Water Commission in the role of a user, which will use the resulting systems to capture validate, store and disseminate Early Flood Warnings.

General:

1. Under National Hydrology Project (NHP), DoWR, RD&GR and its organization CWC will be responsible for flood forecasting activities of the river basins. The size and nature of the Ganga River and its tributaries is a challenge to model using 1D hydrodynamic modeling environment due to extensive braiding of the river channels, particularly in the lower reaches. While the need for 2D modeling along with Early Flood Warning System exists particularly for areas which are nearly flat and are flooded frequently. Also, there is a need to address the breach of flood protection dykes and assess how the existing gates on the dykes should be operated to reduce the likelihood of future dyke failures. 
2. Central Water Commission (CWC) shall be responsible for overall coordination and development of the 2D modeling along with Early Flood Warning System for the entire river basin mentioned above and henceforth called “Early Flood Warning System including Inundation Forecast in Ganga Basin” (EFWS-G) respectively. Stakeholder consultation and data needed for this purpose shall be the responsibility of the consultant involved in these packages.
3. CWC shall be responsible for the development of the Integrated EFWS for the Ganga basin as mentioned above. They shall also be responsible for signing the contracts, contract management, payments etc. for their respective packages/sub packages.
4. The Consultant shall setup teams as indicated subsequently for the above works. 
5. The Consultant has to procure hardware with minimum specification for running 1D/2D or 1D-2D coupled model using a technically feasible high resolution DEM for real time inundation forecast. The hardware will be handed over to CWC after successful completion of the project.
