Return flows which originate from diversions may return during month of the diversion and <br />also in the following eleven months. Return flows which originate from reach losses may not return <br />to the system during the month of loss, but can return to the system during the following eleven <br />months. <br /> <br />4.6.1 Return flow tvoe: Return flows are coded as .one of four types: <br />2 - From site loss, add to natural flow <br />3 - From site loss, add to project flow <br />4 - From canal or reach loss, add to natural flow <br />5 - From canal or reach loss, add to project flow <br /> <br />4.6.2 % of return flow a~sil!Ded: Return flow may return to any station or stations in <br />the network, some as natural water and some as project water. The mechanism for dividing the flows <br />is to have several return flows, each representing a percentage of the total. This field specifies the <br />percentage. <br />If there is a percentage of loss to return flow specified in the diversion or reach loss, then <br />there must be return flow records to return 100% of the flow to be returned. If there is no <br />percentage of loss to return flow specified, then return flow records are prohibited. <br /> <br />4.6.3 Receivinl! station number: The station where the flow will return to the system. <br /> <br />4.6.4 Return flow delav table: Optional. If given, this must be a monthly table of <br />percentages that total 100%. The nO> entry of this table gives the percentage of the return flow <br />(covered by this record) that will return to the system after (n-l) months. If the return flow is from <br />reach losses, the first entry must be zero (see paragraph 5.2.5 [page 31]). <br /> <br />Page 28 <br /> <br />HYDROSS 4.1 <br /> <br />March 25, 1991 <br />
