Evaluation of Ciliwung river water quality can be done by analyzing the distribution dissolved oxygen (DO). The purpose this research is to analyze environmental parameters that affect DO, carrying out predictive modeling estimate DO in River. data used primary and secondary data, some which were obtained from previous studies. are temperature, biochemical demand, chemical power hydrogen, turbi...

Dissolved oxygen (DO) reflects the self-purification ability of a water body and is also an important indicator for quantifying quality. The morphological changes in cross sections river channels will affect hydraulic conditions, distribution pollutants DO may be affected, possibly resulting local deficits pollution. To effectively predict quality, coupled model introduced this study. shallow e...

prediction of spatial and temporal variation of water quality is vital for managing pollutantsdisposal into the rivers. depletion of dissolved oxygen (do) takes place due to the consumption of oxygen bymicrobes to digest bio-degradable pollutants which enter a water course. reaeration takes place in a specificrate depending on do deficit. many investigators have formulated models as an alternat...

Quantifying parameter and prediction uncertainty in a rigorous framework can be an important component of model skill assessment. Generally, models with lower uncertainty will be more useful for prediction and inference than models with higher uncertainty. Ensemble estimation, an idea with deep roots in the Bayesian literature, can be useful to reduce model uncertainty. It is based on the idea ...
