Hydrological Design Aids (Surface Water)
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 Potential-Availability/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

The Regional Models four river systems for water availability are also being developed as part of TOR
North- Satluj River basinNorth East- Lohit and Barak basinsSouth- Godavari River BasinWest- West Coast ( Damanaganga and and Kannadipuzha) and Tapi River basinObjectiveDevelop 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
Regional study : HDA-Y
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
