  8. 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 S-8

  9. 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, Hydrogen, Oxygen , Co2, and Water vapors

  10. TYPES OF PRECIPITATION 1.Convective 2.Orograpic 3.Trough 4.Cyclonic

  12. Inflow The stage-discharge relation Current Meter The discharge measurement A Stream Gauging Stage Gauging Stage Discharge Curve Discharge inflow How Stream flow is Measured Measuring stream stage B Tank Table Data Inflow=Final storage – Initial storage + spills + withdrawals

  13. Hydrologic Modeling

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

  15. Hydrological Analysis for different catchments in Bagh sub basin

  16. Annual Interceptions in minor tanks, K.T. Weirs and Ex Malgujari Tanks

  17. Post monsoon inflows

  18. Annual Yield Bagh Sub Basin

  19. Sub basin Bagh R R Modeling for Water Availability

  20. Godavari Khore in Maharashtra Water Availability

  21. Water Supply Schemes Axum Water Supply Schemes Ethiopia

  22. Rain fall data availability chart

  23. Monthly Rainfall Histogram at Axum

  24. Histogram For Monthly Metrological Parameter At Adwa

  25. Gauged discharge data of Ayehida near Axum The discharge at 0.10 m is zero and therefore zero of gauge (Ho) is considered as 0.1 m. The stage discharge curve is developed as Q= K (H-Ho )n Where = Q = discharge in m3 /sec K = constant

  26. Recommended R-R models for monthly and annual flow estimation

  27. Summery of the estimated flow parameters at Maychew Dam site (Mm3)

  28. Reservoir sedimentation Area Capacity Curve for Maychew Dam

  29. Projected Demand for Axum Town

  30. Reservoir sizing

  31. Synthetic Unit Hydrograph for Maychew Dam site

  32. S curve and Unit Hydrograph Maychew Dam site

  33. Axum storm Analysis

  34. Design Flood • The following standards are used for Design floods. • Indian Standards • Spillway Design:- SPF for dams having storage capacity up to 60 Mm3 or dam height up to 30m and PMF for dams having storage capacity more than 60mm3or dam height more than 30m • Coffer dam:- 5 years return flood or construction period whichever is higher. • ICE (Institute of Civil Engineers, GB) • Spillway design :- • Reservoir at full supply level and 10000 year return period or 0.5 PMF which ever is higher is impinging for standard condition where over topping is not permitted. • Reservoir at full supply level and 10000 year return period or 0.3 PMF whichever is higher for non standard condition where over topping is rarely permitted • Coffer dam • 20 years return period. • As per Indian standard the design flood shall be PMF that is 710.82 m3/s as dam height is more than 30m. The design flood shall be 508.62m3/s as it is more than half the PMF. However it is recommended that the design flood shall be considered as 710.82m3/s because: • It is the water supply project evolving high risk • There is no substantial difference between PMF and 10000 year return period flood • Being on safer side

  35. Flood Routing for Maychew Dam Spillway length 85m,Return Period 10000& PMF years planning scenario 50 year and out flow rating curve

  36. Spillway Analysis 50 year planning scenario 100 year planning scenario

  37. comparison for various length of spillway for Maychew dam plannigsenario for 50 years and crest of dam/ FSL1685

  38. comparison for various length of spillway for Maychew dam plannigsenario for 100 years and crest of dam/ FSL1689

  39. Dam Design Parameters

  40. Recommended Proposal • It is recommended that • Planning scenario as 100 years • Dead storage at RL 1682 m • Spill way length 40m with crest at RL 1689m in initial phase • Installation of 4m high gate over the crest in next phase • Demand drawls at RL 1676 and 1682m which will function as scour sluices also • River scour sluices at RL 1651 • Dam top RL 1695m • These parameters shall be used for designing the project.

  41. Project Management Consultancy, Completion and Operation of Sangola Branch Canal

  42. Special Problems in SBC Project The situation specific problems which compel the need for TAMC Services are as follows: a) Import and Use of Modern canal liningTechnology from USA for carrying out the canal liningunder water for the continuously flowing NRBC through out the year b) Restrictions on use of natural sand and its replacement by crushed sand including concrete mix designs c)Strong opposition from the farmers in existing established perennial irrigation belt under the pretext of adverse effects on their established economy as canal lining will reduce water supply to their established irrigation cropping pattern. This concerns vitally and needs intensified efforts in this regard, to make a dialogue with concerned farmersthrough frequent and consistent persuasion for eradicating the fear of concerned farmers, and d)Regular and frequent (at least bimonthly or quarterly) review meetings of all concerned participants and stake holders by competent catalyst Agency for proper coordination and monitoring in light of above (a),(b) & (c)

  43. Flow Chart Start Literature Review Collection of data Compilation, analysis & Preparing monitoring network in consultation with MKVDC Presentation before Competent Authority Follow up and Feed back Yes No Is It Complete ? End
