These Sankey diagrams illustrates the measures of capacity and exchange of water in the Sacramento/American river confluence. Sankey diagrams are an essential constructive framework to analyze the breaching processes and estimate the manipulated water flows. The work is supported with calculations derived from California Department of Water Resources measurements as a means to describe where flows become broken, crosswired, appropriated, or out of tolerance. While the Sankey should hold a useful matrix to describe a section of a closed system, the Sacramento/American River measurements describe a broken system of flows in which the input of 100% on the top end results in disrupted quantities of output. The gradient edge variable along the edge of the diagrams provides the Sankey with information about the discrepancies between inputs and outputs.
