1. A method of evaluating a gravity-type flow conveyance system having a known geometry, the method comprising the steps of:
- identifying a plurality of access points in the hydraulic conveyance system;
identifying all sources of flow input to the system upstream of each access point identified;
quantifying the expected volume of flow input of each source identified;
totaling the expected flow input from all sources identified upstream of each access point to compute an anticipated flow at each access point;
measuring a depth of flow at each access point;
converting the measured depth of flow to a volume of flow based on the known geometry of the system to compute a theoretical flow at each access point;
comparing the anticipated flow to the theoretical flow at each access point to evaluate whether any restrictions on flow may exist in the conveyance system.

Abstract
A method of evaluating a gravity-type flow conveyance system is disclosed. The method includes the steps of identifying, quantifying and totaling all upstream inflow sources to compute an anticipated flow at a plurality of access points in the system. The actual depth of flow at each access point is then measured and converted to a theoretical flow for each access point. The anticipated flow and the theoretical flow are then compared to determine whether any restrictions on flow might exist in the system and also to prioritize further inspection and repair of the system.
