Initializations 

Municipal water demand

Use SeriesWaterWithdMunicipal to initialize municipal water demand (WatWithdMun).

If null, then calculate urban population:

$UrbanPercent=POPURBAN_{c}/POP_{c}$

Then estimate municipal water demand using the equation: "MunDemandPC (Linear) versus GDP2011PCPPP(MOSTRECENT) (Log) AND Connections" which is in AnalFunc.

$Prediction=(x_{1}*ln(GDPPCP_{c}))+(x_{2}*ln(UrbanPercent))+(x_{3}*ln(WATSAFE_{c,3}))+b$

Multiply municipal water demand per capita by the size of the urban population.

$WatWithdMun_{c}=Prediction*POPURBAN_{r}$

Industrial water demand

Use SeriesWaterWithdIndustrial to initialize industrial water demand (WatWithdInd).

If null, then estimate using manufacturing value added. The equation is, "WaterWithdIndustrial(MOSTRECENT minus elec) (Linear) versus Man (Linear)" and is in TablFunc.

$Prediction=x_{c}*VADD_{c,manufacturing}$

Agricultural water demand

Initialize agriculture water demand using SeriesWatWithdAg.

If null, then set to 0.

Land irrigated

Initialize land irrigated (LANDIRAREAACTUAL) using SeriesLandIrActual%Equip.

If null, set to 90 (percent).

Multiply by land equipped for irrigation:

$LANDIRAREAACTUAL_{r}=LANDIRAREAACTUAL_{c}*(CLandIrAreaEquip_{c}/100)$

If LANDIRAREAACTUAL is still null, then set to 0.001.

Water withdrawal growth rates

Initialize water withdrawal growth rates (WaterWithdrawalSurfaceGR, WaterWithdrawalGroundGR, WaterWithdrawalFossilGroundGR) using the "getAnnualGrowthRate" function and the tables: SeriesWatWithdSurface, SeriesWatWithDGround, and SeriesWatWithDFossilGround.

Total and exploitable renewable resources

Initialize total renewable surface water resources (WatResTotalRenewSurface) using SeriesWaterResTotalRenewSurface. 

If null, set to 0.

Initialize total renewable groundwater resources (WatResTotalRenewGround) using SeriesWaterResTotalRenewGround.

If null, set to 0.

Initialize total renewable water resources (WatResTotalRenew) using SeriesWaterResTotalRenew.

If null set to 0.

Fill holes

If WatResTotalRenewGround is 0 but WatResTotalRenewSurface and WaterResTotalRenew do not equal 0, then:

$WatResTotalRenewGround_{c}=WaterResTotalRenew_{c}-WatResTotalRenewSurface_{c}$

If WatResTotalRenewSurface is 0, but WatResTotalRenewGround and WaterResTotalRenew do not equal 0, then:

$WatResTotalRenewSurface_{c}=WaterResTotalRenew_{c}-WatResTotalRenewGround_{c}$

If WaterResTotalRenew is 0, but WatResTotalRenewGround and WatResTotalRenewSurface do not equal 0, then:

$WaterResTotalRenew_{c}=WatResTotalRenewGround_{c}+WatResTotalRenewSurface_{c}$

If we still do not have any value for WaterResTotalRenew, then estimate using land area:

$WaterResTotalRenew_{c}=x*LANDAREA_{c}$

Subtract overlap between surface and groundwater out. Initialize overlap with SeriesWaterResOverlap.

$WatResTotalRenewSurface_{c}={\dfrac {WatResTotalRenewSurface_{c}}{WaterResTotalSurfaceGround_{c}}}*(WaterResTotalSurfaceGround_{c}-Overlap_{c})$

$WatResTotalRenewGround_{c}={\dfrac {WatResTotalRenewGround_{c}}{WaterResTotalSurfaceGround_{c}}}*(WaterResTotalSurfaceGround_{c}-Overlap_{c})$

If we have data for total renewable water resources (TRWR) but not TRWR surface and ground then we estimate based on the total using global averages. If we do not have data for exploitable surface and ground water resources we estimate using TRWR surface and ground resources.

If WatResTotalRenewGround is still 0 then: $WatResTotalRenewGround_{c}=0.29*WaterResTotalRenew_{c}$

If WatResTotalRenewSurface is still 0 then: $WatResTotalRenewSurface_{c}=0.71*WaterResTotalRenew_{c}$

If WatResExploitRenewGround is 0 then: $WatResExploitRenewGround_{c}=0.89*WatResTotalRenewGround_{c}$

If WatResExploitRenewSurface is 0 then: $WatResExploitRenewSurface_{c}=0.36*WatResTotalRenewSurface_{c}$

WatResExploitRenewSurface was initialized using SeriesWaterResExploitSurface and WatResExploitRenewGround was initialized using SeriesWaterResExploitGround.

If total exploitable is 0 then use sum of surface and ground: $WaterResTotalExploit_{c}=WatResExploitSurface_{c}+WatResExploitRenewGround_{c}$

If total renewable is still 0 then use sum of surface and ground: $WaterResTotalRenew_{c}=WatResTotalRenewSurface_{c}+WatResTotalRenewGround_{c}$

Withdrawals (by source)

AQUASTAT includes fossil water withdrawals in their groundwater withdrawal data so we must subtract it out.

$WatWithDGround_{c}=WatWithDGround_{c}-WatWithDFossilGround_{c}$

The fossil water reserve data we have (WaterResGroundAfrica) also includes both renewable and fossil, so we must subtract out renewable.

$WATERRESFOSSIL_{c}=WaterResGroundAfrica_{c}-WatResTotalRenewGround_{c}$

If we do not have fossil water data resources (WATERRESFOSSIL) but we do have fossil water withdrawals (WatWithDFossilGround) then we estimate that withdrawals are 10 percent of reserves.

$WATERRESFOSSIL_{c}=10*WatWithDFossilGround_{c}$

If we have no data for either fossil water reserves or withdrawals, then assume they are 0.

If we have data for both total renewable withdrawals and groundwater withdrawals, we estimate surface water withdrawals:

$WatWithDSurface_{c}=WatWithDTotalSources_{c}-WatWithDGround_{c}$
