# Data Set Names in .RST2 files

Unless otherwise stated units are in metres.

Slope: The drop in metres across a grid square, pixel, etc. If the physica lunits option in the runoff model is selected then the slope is in units of metres/metre

Spatial: This is a variable that allows random variation of properties in space. The appropriate variable is multplied by the value of spatial (thus typiocally spatial has a mean of 1)

Gully: This is the result of the Channel Initiation Function indicating whether a gully has eroded at the point. The units are defined by the value of the parameter input. If Gully=1 then a gully is present at that point. ID Gully<0.1 then a gully does not occur at that point and the point is hillslope. This value is used to determine the erosion rates in the gully and hillslope and (if the physical gully module is turned on) to determine the depth if there is a gully at that point (see below)

Elevation: In metres

Area: This is the area of the catchment draining through that node in units of pixels. If the physical unis options in runoff model is selected then the units are in square metres.

Network: This is a code indicating in what direction the flow is draining from that node. It is based on the D8 model. In Viewer the actual codes are not diaplayed bu the drainage network that results from the drainage directions in the DTM.

Gully Depth: If the physical gully module is turned on this is the depth of the gully at that point. If the physical gully module is not turned on then all values are 0.0.

Soil Depth (Research Version): If the soil development module is turned on then this is the depth of the soil at that point. If the soil module is not turned on then all values are 0.0.
