Water Scarcity Quiz

Question 1A region has 36000000 m³ of usable water available for a year and 24000 residents. Find the annual amount per resident in m³/person, rounded to one decimal place.

Enter a number in m³/person.

Answers within 0.05 m³/person of the expected value are accepted.

Question 2During a month, a reservoir receives 18 million m³. Evaporation removes 3 million m³, downstream releases 6 million m³, and withdrawals 11 million m³. Find the storage change in million m³, rounded to one decimal place.

Enter a number in million m³.

Answers within 0.05 million m³ of the expected value are accepted.

Question 3Usable water lies beside a settlement, but residents lack an affordable delivery network. What type of constraint explains its shortage?

A drought defined by the failure to install service pipesA lack of demand inferred from residents’ inability to payA financial and infrastructural barrier to a usable supplyA physical absence of water from the surrounding catchment

Question 4Water use rises beyond reliable supply during a year of normal rainfall. Which distinction matters?

Demand-related scarcity differs from an unusually dry climate periodHigh demand means the region’s climate has become wetterA shortage changes the historical rainfall average immediatelyNormal rainfall rules out a shortage for the stated users

Question 5Wells keep delivering water while aquifer withdrawals repeatedly exceed recharge. What does continued pumping conceal?

A rise in natural replenishment equal to the pumping rateA conversion of groundwater into a new annual river inflowAn inexhaustible supply demonstrated by each working wellA decline in stored groundwater despite current deliveries

Question 6An irrigation upgrade reduces runoff that previously supplied farms downstream. What must a basin-wide saving estimate follow?

The paths taken by unused flows and subsequent farming demandThe equipment’s efficiency label replacing measurements of flowsThe number of new devices fixing the amount left downstreamThe reduction at one intake as the basin’s final saving

Question 7A factory withdraws water and returns most of it clean to the same basin. Which statement correctly accounts for the water used?

The returned flow adds rainfall to the basin’s water balanceThe permit allowance specifies the actual amount returnedThe full intake becomes a lasting reduction in basin supplyThe withdrawal is larger than the amount lost to immediate reuse

Question 8A coastal city considers desalination as an extra source. Which constraints remain in the proposal?

An absence of operating costs once seawater enters the plantAn unlimited inland supply independent of pumping infrastructureThe power supply together with waste disposal and delivery needsA freshwater output equal to intake with no concentrated remainder

Question 9Users dispute withdrawals during a low-flow season. Which arrangement makes allocation more accountable?

The earliest claimant’s demand fixing the supply available to everyoneEnforceable permissions with monitoring and a way to revise themThe annual regional average replacing checks at individual intakesA permit title establishing that actual withdrawals stay within it

Question 10A wet city has polluted sources and unreliable household taps. How should its annual precipitation figure be interpreted?

A direct reading of affordability across neighborhoodsA climatic input distinct from the supply reaching each customerA guarantee that treatment and storage capacity are sufficientA measure of safe delivered water for each household
