CONSULTANCY SERVICES FOR
FEASIBILITY STUDY FOR DESIGN OF RIVER
TRAINING AND FLOOD PROTECTION WORKS IN
PUNJAB, PAKISTAN 1. BACKGROUND
The Province of Punjab experienced heavy loss of life and property due to heavy rainfall
and ensuing devastating floods in various rivers on 11th to 14th September 2014. Many
habitations located along the river banks have become vulnerable and susceptible to losses due to
unprecedented floods and toe erosion. It is therefore proposed to carry out extensive study of the
morphology of the identified rivers together with their hydrological parameters, as precursor to
effective river management.
The Province of Punjab is vulnerable to multiple natural hazards of which flood and flash
flood are important ones. Floods and flash floods, caused by cloudbursts or intense rainfall
events and glacial moraine, are common in Pakistan. These have adverse impact on the life
support strategy of the people of the Province. It is important to note that the habitations around
the rivers contribute significantly towards total agricultural and industrial product value of the
country and any disruption in these areas is sure to be reflected adversely on national growth and
development statistics. Thus, flood control and river management by conducting detailed
feasibility study in this area has vital importance for social and economic development of the
nation. This would ensure timely corrective action so as to minimize future devastation.
2. OBJECTIVE The objective is to study, identify and document areas/stretches where the stream flow is
likely to have adverse physical, environmental, social and economic impact from changing river
morphology, particularly during high discharge caused by episodic events such as flood from
very heavy rainfall or sudden discharge from upstream reservoirs. The study intends to undertake
economic/cost benefit analysis of river training and flood protection works. The study and design
of river training and flood protection works is also intended to provide detailed solutions,
including engineering design and other nonstructural measures, of the various flood control/
mitigation measures and channel improvement measures near habitations along the river course
so as to reduce the impact of the flood disaster on human life and property by taking into account
environmental and social aspects. 3. SCOPE
The purpose of the feasibility study is to identify vulnerable areas (habitation, public or
private infrastructure, agricultural land) where rivers pose threat from morphological changes
that has resulted over a period of time and those from episodic events such as excessive rains,
cloud bursts and glacial phenomena. The consultancy will proceed in single stage to undertake a
detailed assessment around populated and critical vulnerable areas and come up with remediation
measures that can be taken up in due course of time. The consultancy would address the following;
1. River hydrology and hydraulics to understand impact in the flood plain; effect of episodic
events such as cloudburst, excessive rainfall on the hydraulic conditions of the river; 2. Evaluate flood plain encroachment and impact on river behavior; 3. Evaluate effectiveness of existing river training and flood protection works, recommend flood
resilient solutions to strengthening existing protection works and proposed structural and
nonstructural measures at problematic river reaches by providing design of new structures
with detailed physical and numeric modelling where applicable;
4. Carry out screening and identify social and environmental impacts and propose mitigation
measures for river training and bank protection works. Also prepare required environmental
and social documents/plans for the river training and flood protection works; 5. Carry out economic and cost benefit analysis of river training and flood protection works.
It is proposed to include the rivers and stretches mentioned below:

4. TASKS, SUB-TASKS, DATA REQUIREMENTS & DELIVERABLES 4.1 Task & Sub-Task
Task1. Identification of most vulnerable stretches which are posing or can pose risk to the
habitation and available public and private infrastructures along the different river reaches. Sub Task 1.1 Define criteria for selecting reaches to design river training and bank protection
works. The criteria should clearly define the hazard, exposure, vulnerability and risk assessment
which provide decision-making process by providing information essential to understanding the
nature of the community’s risk. The criteria may be based on: Flood damage, threat to
cities/villages, agricultural/ irrigation fields, lines of communication, public utilities etc.; Bank
erosion posing threat to important towns and other populated areas, roads, railways; Significant
lateral shifting of the river posing threat of outflanking of important structures like bridges,
barrages etc. besides bank erosion. Significant shifting of the river away from the
Barrages/Headworks causing water shortage for irrigation, drinking and industrial use etc.
Sub Task 1.2 Topographic/X-Sectional Survey of Entire River reaches mentioned in Table-1 at
1 Km interval across high banks of rivers. Sub Task 1.3 Conduct physical model study of entire river reaches as mentioned in Table-1
