All parameter values for the receiving water are entered here. They are grouped by impacts (NH3, Hydraulics and Solids). Values of parameters listed on the tab System are always needed. If an impact is not activated then editing of the corresponding parameter values is disabled.
System
| Baseflow [m3/s]: | Discharge during dry weather (approx. Q347, the discharge that is reached or exceeded during 347 days per year or 95% of the time) |
Hydraulics
| Strickler Coefficient [m^(1/3)/s]: | of the channel bed |
| Channel Slope [-]: | slope of the receiving water (not in %o) |
| Channel Width [m]: | width of the receiving water |
| Side Slope x:1 (H:V) [-]: | of the bank for a vertical distance of 1 (0: rectangular channel, 1: 45 degrees) |
| Average Grain Size [m]: | of bed material |
| 90% Grain Size [m]: | of bed material |
NH3
| NH4-N Concentration [mg/l]: | ammonia concentration in the receiving water |
| pH Value [-]: | pH value in the receiving water |
| Alkalinity [mmol/l]: | in the receiving water |
| Min. Temp. (February) [C]: | in the receiving water |
| Max. Temp. (August) [C]: | in the receiving water |
Solids
| TSS Settling Velocity [m/s]: | used to calculate accumulation of TSS |
| Erosion Coefficient [g/m2/s]: | used to calculate erosion of accumulated particles |
| Degradation Rate of org. Matter [1/d]: | used to calculate degradation of the organic part of accumulated TSS during dry weather |
| Critical Shear Stress [N/m2]: | determines, if accumulation (τ <= τ crit) or erosion (τ > τ crit) occures |
| gO2/gTSS from Combined System [-]: | fraction of organic matter in TSS discharged from combined sewer system |
| gO2/gTSS from Separate System [-]: | fraction of organic matter in TSS discharged from separate sewer system |
