Comprehensive Hydrological Studies Presentation Overview

This presentation by Bhama Consultancy Services focuses on hydrological studies within the Bagh sub-basin in Pune. Covering the hydrological cycle, types of precipitation, and rainfall measurement techniques, it provides insights into water distribution and movement beneath the earth's surface. Key topics include stream gauging, hydrologic modeling, and rainfall analysis over various catchments. The analysis includes monthly and yearly yield series, ensuring a thorough understanding of water inflow and watershed dynamics. This informative session aims at enhancing knowledge of hydrological impacts on local ecosystems.

  1. WELCOME Bhama Consultancy Services , Pune START

  2. Presentation on Hydrological Studies Location:DIRD,PUNE Date:2 JUNE 2011 Next

  3. What is Hydrology? It is the science which deals with occurrence ,movement and distribution of water upon ,over and beneath the earth surface .It is in the form of cycle and known as hydrological cycle

  4. Hydrological Cycle

  5. PRECIPITATION It is the fall of water in various forms on the earth from the atmosphere. It is in the form of rain , snow, hail, and dew Air contains gases/such as Nitrogen,Hydrigen,Oxygen ,Co2, and Water vapors

  6. How Precipitation Occurs ?

  7. Types of Precipitation Convective Orograpic Trouph Cyclonic

  8. I Convective

  9. I.Orograpic

  10. III.Trouph

  11. VI.Cyclonic

  12. Standard rain gauge station

  13. Auto Recording Rain gauge Station

  14. Spatial Distribution Rain fall measured by RG is point rain fall it varies over time and spare

  15. Bagh Sub Basin- Isohyets ( Annual Average Rain Fall)

  16. Time series Time series for weighted average rain fall over the sub basin Parameters Max Min Average STD CV Dependability 95% 90% 75% 60% 50%

  17. Inflow A Stream Gauging Stage Gauging Stage Discharge Curve Discharge inflow B Tank Table Data Inflow=Final storage – Initial storage + spills + withdrawals

  18. The discharge measurement

  19. The stage-discharge relation

  20. Measuring stream stage

  21. How Stream flow is Measured

  22. Hydrologic Modeling

  23. Bagh Sub-basin , Groups of catchment and Thissen Polygon

  24. Hydrological analysis for Bagh Sub-Basin Rain fall Analysis a)Weighted average rain fall series over the Sirpur catchment for June b)YearwiseMonthly Weighted average Rain fall Sears over Sirpur catchment 2.Yeald Analysis Daily Monthwise inflow at Sirpur Historical Monthly inflows at Sirpur 3.R R Modeling -Calibration –June – October for sirpur 4.
