Hydrology Project-II”
Hydrological Design Aids (Surface Water)
January 29, 2014
By
Central Water Commission
Objectives of HDA-SW
• Main objective of development of HDA (SW) is
to standardize Hydrological Design Practices in
the form of design aids for uniform use, all
over the country, using state of the Art
technology to the extent possible.
• Aims at consolidating various design
practices/tools for different design parameters
Components of HDA
As required in hydrological study of any project, the
HDA includes following three modules:
 HDA-Y: Assessment of Water Resource PotentialAvailability/Yield Assessment
 HDA-F: Estimation of Design Flood
 HDA- S: Sedimentation rate estimation
Apart from various analytical tools, the project also
includes preparation of reference manuals and
design aids to produce the hydrology chapter of the
DPR as per standard guidelines of MoWR

Regional study : HDA-Y
The Regional Models four river systems for water
availability are also being developed as part of TOR
North- Satluj River basin
North East- Lohit and Barak basins
South- Godavari River Basin
West- West Coast ( Damanaganga and and
Kannadipuzha) and Tapi River basin
Objective
Develop relationships to enable computation of monthly yield
series for Monsoon season for an ungauged sub-basin using data
on climatic parameters, catchment Characteristic, Land use etc.
Status
– Work of Tapi basin and Damanganga has been
completed and work of Godavari basin is in progress
Empirical Relations
• Developed empirical equations for the formed
clusters were both, month-wise and monsoon
season relate the dependent variable discharge
(Qsim) with the independent variables namely
Precipitation (PCPM), Temperature(TEMPM),
Relief (RL), “% Crop Area (%CA), “% Forest Area
(%FA) and Unit Area of the sub basin (UA).
Qsim= 0.739×(PCPM) + 19.686×(TEMPM) + 0.041×(UA) 0.089×(RL) + 1.28×(%CA) -1085.98
Correlation coefficient (R) : 0.94
Concluding
This project will help in consolidating various
design practices/tools for different design
parameters
Will infuse standardization in the process of
hydrological design parameters estimation
and preparation of Hydrology chapter of DPR
Will help in reducing time period for
assessment of parameters and their appraisal
Creating data bases
Training to State Engineers
