Also for each ditch structure, the user will specify <br />whether water diverted through the structure was used for (a) diversion outside of the basin <br />(ex), (b) bypass of the USGS gaging station (by), (c) diversion into the basin (im), or (d) <br />municipal (mu). The user will specify for each ditch structure an adjustment factor (0.50, 1.00, <br />etc.) that could be used to increase or decrease the amount of water diverted through the <br />structure. The default adjustment factor will be one. <br /> <br />The user will specify one of two options for monthly municipal return flow factors that <br />? <br />represent sewage effluent return flows and lawn irrigation return flows. Table 3 shows default <br />monthly municipal return flow factors for Option No. 1. <br />TABLE 3.
