PROCESSING Of THIS DEMAND IS COMPLETE. STORE THE FLOW IN THE RIVER
IN THE TOTOT TABLE FOR THIS SEQ. PT. RETURN TO THE BEGINNING OF
HYORBAl AND PROCESS THE NEXT SEO. PT.

.... IF THE SEQUENCE POINT IS A RESERVOIR DO THE FOLLOWING:

STORE THE INFLOW IN THE RESERVOIR. (THE INFLOW = THE FLOW IN THE RIVER
AT THE SEQ. PT. IMMEDIATELY U/S OF THE RESERVOIR).
SET THE CONTENTS = THE TARGET STORAGE CONTENTS FOR THE MONTH.
ADJUST THE RESERVOIR RELEASE TO OBTAIN THE TARGET CONTENTS.
ADJUST THE CONTENTS AND THE RELEASE TO MEET CONTENTS AND RELEASE CONSTRAINTS.
COMPUTE EVAPORATION, BANK STORAGE, ELEVATION. AND AREA.

IF THE RELEASE WAS FLAGGED ABOVE IN PWRSIM, ADJUST THE RELEASE AND RECHECK THE
CONSTRAINTS.

BEGINNING OF HVDRBAL AND PROCESS THE NEXT SEQ. PT.

*.** IF THE SEQUENCE POINT IS AN INFLOW DO THE FOLLOWING:

IF THE INFLOW POINT IS A TEMPORARY STORAGE POINT FOR A LAGGED RETURN FLOW,
CAll CHMTT:

OBTAIN THE QUANTITY AND THE QUALITY OF THE FLOW THAT HAS BEEN LAGGED TO RETURN
THIS MONTH AND PLACE THEM IN THE INFLOW VARIABLE AT THE C!S SEQ. PT. WHERE
THE RETURN FLOW RETURNS TO THE RIVER. THEY WILL THEN BE PROCESSEO WHEN THAT
o/S SEQ. PT. IS REACHED.
RETURN TO THE BEGINNING OF HYDRBAL AND PROCESS THE NEXT seQ. PT.

AOD THE INFLOW TO THE FLOW IN THE RIVER.
IF THE FLOW IN THE RIVER IS POSITIVE, STORE THE FLOW IN THE RIVER
IN THE TQTOT TABLE FOR THIS SEO. PT. RETURN TO THE BEGINNING OF
HYDRBAL AND PROCESS THE NEXT SEQ. PT.
IF THE FLOW IN THE RIVER IS NEGATIVE, CALL ON U!S RESERVOIRS
FOR A POSSIBLE SUPPLY AS FOLLOWS:

RANK THE U!S RESERVOIRS THAT ARE DESIGNATED TO SUPPLY ADDITIONAL WATER IN
DESCENDING ORDER BY THE SIZE OF THEIR CURRENT SURFACE AREA.

* IF THERE IS NO U/S WATER SUPPLY AVAILABLE, PRINT A NEGATIVE INFLOW
* SHORTAGE MESSAGE AND SET THE FLOW IN THE RIVER = 10 AF.
* STORE THE FLOW IN THE RIVER IN THE TOTOT TABLE FOR THIS SEQ. PT.
