A subroutine to kinematically route unpressurized, free-surface flow through circular conduits (storm drains, culverts, etc.) has been added to the general source code. This type of element was available in the original version of KINEROS. For backwater conditions at the inlet, use a pond element to control inflow into the pipe. Sediment from upstream elements is also routed through the pipe element, with both deposition and erosion of deposited material being possible during a flow. The new routine should be regarded as "beta" code, i.e. it has not yet been thoroughly tested.
We have a KINEROS2 wordfile and tag list for UltraEdit, the popular shareware text editor for programmers. The wordfile provides syntax highlighting when editing KINEROS2 parameter and rainfall files. The tag list is a comprehensive set of input tag descriptions -- when the highlighted description is double-clicked the corresponding tag is inserted into the file at the current cursor position.

A desktop geographic information system (GIS) interface to KINEROS is being developed by scientists at the SWRC in coordination with the Landscape Ecology Branch of the US-EPA. When completed, this interface will perform the automated parameterization of KINEROS for a specified watershed. Written for ArcView GIS, the interface requires that the user have three commonly available GIS data layers: a digital elevation model (DEM; available from the USGS at http://earthexplorer.usgs.gov), soil data such as STATSGO or SSURGO, and land cover information such as the US-EPA North American Land Classification data. The interface is designed to be intuitive and relatively easy for non-hydrologic modelers to use. The intended audience for the interface is composed of research scientists, land managers, action agencies, and non-scientists interested in investigating the roles of topography, soil, and land cover on the hydrologic response of a watershed.
