Abstract:
The main objective of this research is forecasting the river flow in Batang Ombilin.
Discharge forecasting is very important to be accommodated in the study of water
availability to determine how the trend and forecasting river flow conditions in the future.
Modeling approach used river flow forecasting process in Batang Ombilin was moving
average. This model is a time series forecasting model with Qm for Windows 2. Research
data sourced from secondary data Department of Public Works water resources sector
with the length pf the data from 2003 to 2010. The results show that using the length of
data 6 year using a weighted moving average model able to predict up to 2 months
