ANALISIS PENGARUH HIDROLIKA SUNGAI TERHADAP TRANSPORT BOD DAN DO DENGAN MENGGUNAKAN SOFTWARE QUAL2E (STUDI KASUS DI SUNGAI KALIGARANG, SEMARANG )

摘要: People and industrial activity along Kaligarang River increase day by day, cause load of river increase too. has many function to support human life, so monitoring river is needed Monitoring  of  river  water quality  in  some  places  need  many  expenses  and  can  not  give information  abaout  quality comprehensively.  That  is  why,  it’s  needed  a  quality modeling for river. In this case, it’s used Qual2E one the water modeling software. To use software related characteristic, still needed justify some coefficients   and  get  validation  related  to  reaction  pattern  among  constituent,  hydraulic  condition,  and hidrology aspects. The research proposed see process calibration model related to justification coefficient.And so, analyze influence hydraulic aspects to the BOD DO pattern. It’s secondary data, i.e. sampling, climatlogy, hydrology (discarge river), aspects, map, point source.The done related data coefficient get suitable River. This  calibrated  model  validated  by  the  secondary  data,  i.e. sampling  from Bappedal Province Central Java. And simulation with various aspects, i.e. “n” number Manning, cross section, Simongan dam. conclusions of say that there are influences relationships BOD and
