The term 'high-level' alluvia refer to alluvia deposited in ancestral valleys which are located above the channels in the current landscape in a form of inverted relief. Over time a channel will erode through older alluvial deposits resulting in older alluvia appearing in the banks above the channel. This model shows the process of terrace development and does not show groundwater.
