## Abstract
Abstract This research aims to analyze the correlation between water efficiency, water losses, and channel density in the secondary channels of Bissua irrigation and figure them spatially. Channel was sampled purposively for different dense of a channel in the area based on irrigation channel map. The water inflow and outflow were measured in the selected segmented channels. Discharges, evaporation, and seepage data were used to determine water losses and their efficiencies. Spatial mapping was processed using ArcGIS 10.4 to figure the location of channels with their value of efficiencies and losses. The result shows that losses and efficiency range from 1.2 to 4.7 ×10-4 m 3 /s/m and 40 to 90%, respectively. The variation of channel density from 0.03 to 0.25 km/km 2 found a negative exponential correlation between water efficiency, water losses, and channel density. In addition, water losses also have a positive correlation to the width of channels.
