7 TRENCH MODELING AND RESULTS Hydraulic calculation for ACO DRAIN channel systems (Based on the differential equation for steady, non-uniform, flow in open channels) Project: Carinarnica Kraljevo Design Office: Run Identity: 7 Comparison of these hydraulic profiles induced division of trench drain into 5 equal length sections, with the appropriate catchments subdivision. Clear Height (mm) Flow Depth (mm) (m/s) (mm) (l/s) m 1.12 % m (mm) (l/s) Datum Input Liquid: Water Kinematic viscosity (cm²/s): 0.01 ACO DRAIN System: V 100 Multiline Roughness coefficient: 95 Outlet type: Results Outflow (l/s): Minimum freeboard (mm): -5.99, X = m Channel capacity (%): Copyright ACO Eastern Group NOTE: Flow velocity (m/s) Outflow (l/s) Vertical scale 1: Horizontal scale 1: The calculation assumes that the channel flow is not restricted by the capacity of the continuing sewer system.

8 SENSITIVITY ANALYSIS - ROUGHNESS AND PONDING The scenarios of limited sensitive analysis are: channel K7 is rectangular with roughness n = or n = 0.024, with no ponding area in junctions channel K7 is rectangular with roughness n = or n = 0.024, with ponding area of 10m 2 in junctions

9 CONCLUSIONS The design flow capacity for channel decreases with Manning s n-value increase Peak inflows to middle positioned junctions are higher when pond areas has been jointed to trench drain Peak outflows at the end junction are higher when pond areas has been jointed, the difference might been significant for network sizing
