摘要：The Upper Belik watershed is a river that flows in Special Region of Yogyakarta. Land use in this watershed is dominated by settlements. The development activities by the human can cause river pollution if there are no maintenance and monitoring retated to their waste. The study aims to determine the waste load and capacity of the BOD. The descriptive quantitative with spatial analysis is used. The determination of the sample is by dividing the study area into five segments based on variations in pollutant sources and drainage flow directions. Water sampling and river morphological measurements were carried out purposively, water quality taken by grab sampling. Data are processed using the Water Quality Analysis Simulation Program (WASP). The results showed that Belik River could not accommodate waste loads. Segment one has to reduce 22,41 kg/day BOD, while the second segment does not need to reduce the load. Segment three must reduce as much as 5,73 kg/day, segment four by 35,81 kg/day and segment five by 61,16 kg/day. Reducing the waste load can be done by reducing the pollution load that flowing to the river.
