35 Design Flood The following standards are used for Design floods. 1.Indian Standards Spillway Design:- SPF for dams having storage capacity up to 60 Mm 3 or dam height up to 30m and PMF for dams having storage capacity more than 60mm 3 or dam height more than 30m Coffer dam:- 5 years return flood or construction period whichever is higher. 2.ICE (Institute of Civil Engineers, GB) Spillway design :- a.Reservoir at full supply level and year return period or 0.5 PMF which ever is higher is impinging for standard condition where over topping is not permitted. b. Reservoir at full supply level and 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 m3/s as dam height is more than 30m. The design flood shall be m3/s as it is more than half the PMF. However it is recommended that the design flood shall be considered as m3/s because: It is the water supply project evolving high risk There is no substantial difference between PMF and year return period flood Being on safer side

Recommended Proposal

43 Project Management Consultancy, Completion and Operation of Sangola Branch Canal

44 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 lining Technology from USA for carrying out the canal lining under 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 farmers through 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)

60 The DSS (P) component is under implantation with: DHI Water Environment Health / Consultant providing and customizing the soft ware State Implementing Agency by formulating the objectives /scenarios and providing the information and data required for it and NIH as a catalyst agent for effective technology transfer. It appears that Consultant desires prominent and major role of state implementing Agency for using the already prepared and proofed software where as state implementing Agency desires to tailor the software as per the required objectives /scenarios of the state implementing Agency. NIH is silent observer being a non technological and policy domain. Thus there appears to be a large grey area and causing hindrance in synchronizing and achieving the integrated effective outcome. It is therefore necessary to have a third party intervention right from now to till the completion of the assignment and TAMC will be the appropriate agency for it. However it needs appropriate approval and sanction of competent authority and shall be processed accordingly Present DSS (P) Status

61 HDA 1 Assessment of Water Resources Potential- Availability/ Yield Assessment This study has been developed to estimate the water yield series at any point of interest across the stream or any other point at different levels of dependability. There may be three different cases for which water yield estimation may be needed viz; Gauged Catchment (all data with desired length available) Partially Gauged Catchment (all data with partial length, partial data with full length or discontinued data is available) Ungauged Catchment (No data within study area available) Keeping in view the above aspects, all the methodologies with proper provision of data consistency tests, filling and missing gaps, extension of series (rainfall & runoff, runoff- runoff or any other combination etc.) on different time steps has to be developed for all the data scenarios as stated above. This includes synthetic generation of yield series of desired length (40-50 years).

62 HDA 2 Estimation of Design Flood Estimation of the design flood is essential for the safety aspects of various components or water resources projects. The HDA 2design aid will include all the standard approaches (method, time projection, structures category and downstream hazard classification (if applicable)) for design flood estimation for different purposes. Here also three scenarios may exist. All hydro-meteorological records within project catchment are available; Partially observed data of that catchment and / or reasonably defined records at neighboring catchments; and No observed data are available. HDA 2 will incorporate all approaches currently being followed in India (hydro- meteorological, statistical and regional) with possible improvements and also in conjunction with internationally used methodologies. The design flood value should be chosen on the basis of critical comparison of results of two or three best methods, including standardized methods.

63 The HDA 3 comprises of seven tools which cover two legacies and five in-house developed software. A data storage software for local storage of various data viz. spatial, location, time series and relational will be provided. Under HDA 3 following tools/ design aids will be developed for sediment rate estimation and its distribution in a proposed project. 1.Development of software tools for covering procedures for assessing silt rates using observed silt data or reservoir resurvey data. 2.Providing design aid in the form of regional sedimentation rates for the seven zones of India using the observed silt inflow data and the reservoir resurvey data. 3.Developing regional models for sediment yield using the procedure proposed by Garde and Kothyari (1987), for seven identified regions within seven zones of India. 4.Development of procedures and interfaces to use spatially distributed model MWSWAT for determination of sediment yield from various sub areas using spatial nature of the analysis. 5.Trap efficiency of any reservoir is presently estimated using Brune Curve. The software tools will be developed to use these relations or the revised relations which are proposed to be developed using Indian sediment inflow and reservoir resurvey data. 6.Sediment Distribution pattern in proposed reservoirs is at present estimated using Empirical Area reduction method. The software tools will be developed to use these procedures. Indian reservoir survey data will be utilized to develop relationships for predicting sediment distribution pattern in reservoirs. 7.1-D numerical models are used for assessing sediment transport and deposition in rivers and reservoirs. It is proposed to develop software interface for using HEC-RAS model in situations where necessary data is available. The data required for the sedimentation studies will be the discharge and silt data observed at various gauging sites along with the physiographic details, geology, soil and land use in the catchment as also the reservoir resurvey data of the existing reservoirs in the area. Interfaces with HDA will be developed for various data storage software, data processing and data validation software which are being used such as HYMOS, SWDES, WISDOM and WRIS. The HDA is proposed to have Open Ml interface, which will facilitate interlinking with all Open Ml complaint software. HDA 3 Tools identified in
