Question 10 ప్రశ్న 10

What is one of the most important inherent storage conflicts between flood control and conservation purposes in a multipurpose reservoir?

A Flood control benefits from available empty storage, whereas water-supply and irrigation purposes generally benefit from retaining adequate stored water B Both purposes always require the reservoir to remain completely empty C Both purposes always require the reservoir to remain at maximum level D Flood control requires no storage space while conservation requires only spillway discharge

Question 11 ప్రశ్న 11

During a prolonged drought, a multipurpose reservoir has insufficient water to fully satisfy municipal supply, irrigation releases and normal hydropower generation. Which statement is most appropriate?

A All purposes can still receive their unrestricted normal demands because multipurpose storage eliminates scarcity B The reservoir should automatically be emptied to maximize hydropower regardless of other purposes C The project should cease considering its authorized purposes once drought begins D The purposes may compete for limited storage, so releases must follow established priorities, operating rules and applicable constraints

Question 12 ప్రశ్న 12

Why can the target reservoir level or allocated flood-control space be varied seasonally in a multipurpose project?

A Because reservoir capacity physically disappears during part of the year B Because seasonal changes in flood risk and conservation demand can justify different storage targets at different times C Because hydropower can be produced only in one fixed month D Because seasonal operation guarantees that every future inflow is known exactly

Question 13 ప్రశ్న 13

Which description of inactive or dead storage in a reservoir is generally most appropriate at introductory water-resources level?

A It is the normal storage allocated entirely to irrigation releases B It is storage that must always be used first for hydropower peaking C It normally lies below the active operating range and may provide space for sediment deposition or a minimum pool D It is identical to the flood-control storage that is normally maintained empty

Question 14 ప్రశ్న 14

A planner is comparing an irrigation-only reservoir with a proposed multipurpose alternative serving irrigation, water supply, flood control and hydropower. What is the most appropriate planning approach?

A Evaluate the combined system benefits, costs, operational interactions and constraints of the purposes rather than considering each purpose in isolation B Assume that adding each new purpose automatically improves the project regardless of cost C Ignore conflicts in reservoir levels because multipurpose projects cannot have competing objectives D Select the alternative having the greatest number of stated purposes without further analysis

Question 15 ప్రశ్న 15

When estimating the total benefits of a multipurpose project, which practice is necessary for a sound economic comparison?

A Count every claimed benefit twice to allow for uncertainty B Exclude flood-control benefits because they are not water uses C Treat project construction cost itself as an economic benefit D Identify benefits attributable to each purpose while avoiding double counting of the same underlying benefit

Question 16 ప్రశ్న 16

An existing irrigation reservoir is being considered for an added hydropower facility. Using annual-equivalent values, the hydropower addition would provide benefits of ₹18 crore per year and impose incremental annual-equivalent costs of ₹12 crore per year. Considering only these stated incremental values, which conclusion is correct?

A The addition has an incremental net benefit of −₹6 crore per year and a benefit-cost ratio of 0.67 B The addition has an incremental net benefit of ₹6 crore per year and a benefit-cost ratio of 1.50 C The addition has an incremental net benefit of ₹30 crore per year and a benefit-cost ratio of 2.50 D No comparison can be made even with the annual-equivalent benefits and costs given

Question 17 ప్రశ్న 17

Compared with a multipurpose reservoir, what can be a practical operational advantage of a well-defined single-purpose reservoir?

A It automatically produces a larger total social benefit in every case B It is unaffected by hydrologic uncertainty C Its operating rules may be simpler because fewer competing project objectives need to be reconciled D It never requires storage allocation or release decisions

Question 18 ప్రశ్న 18

A flood has filled much of a reservoir's designated flood-control space. Once downstream river conditions permit, what is generally the appropriate operational action?

A Make controlled releases to restore flood-storage capacity while respecting downstream constraints B Retain all floodwater permanently in the flood-control space C Immediately release the entire stored flood volume regardless of downstream conditions D Convert the flood-control pool permanently to sediment storage
