The Determination of River Order Classification with ArcGIS Application

Abstract

River is a natural or artificial water channel or container in the form of a water drainage network and the water in it, starting from the upstream to the estuary, where based on this understanding the river has a discharge and size dimensions. Based on the discharge and size dimensions, rivers can be used for human needs and a place for the development of aquatic life so that it can affect the ecosystem and must be protected and not be disturbed. However, not all rivers can be used for human needs and a place of life. This study will discuss the types of rivers and the classification of stream orders based on the laws and regulations in Indonesia. Therefore, decision can be made whether the rivers that located in densely populated areas and areas of economic facilities can be modified in form and location according to human needs or must be maintained based on the original nature shape.
