Landscape

Introduction

The landscape of a river corridor is defined by its topography, which can be interpreted on the basis of different structural features layered on top of each other at different scales. The basic topography of a river is actually rarely mapped and monitored, even though this is the single most important piece of environmental information one needs to know to properly manage and river to maintain it in good condition. Luckily, the Lower Yuba River has been mapped several times. From the maps, we have been able to figure out the kinds of valley regions in the river corridor, river "reaches" along the 37-km of channel, and localized landforms. All of these have been mapped and analyzed, and hopefully willbe monitored through time.

Because rivers are dynamic and change through time, it is important to monitor sediment fluxes into, through and out of the river. Also, by observing how topography changes through time, it is possible to assess how and why the landforms are changing.

This section of the website deals with all of these issues about the physical structure of the LYR.
