Webpower per unit length (W) or the power per unit riverbed area (w). Bagnold [1] denoted the stream power in the following way: “The available power supply, or time rate of energy supply, to unit length of a stream is clearly the time rate of liberation in kinetic form of the liquid’s potential energy as it descends the gravity slope S”. Web29 Jan 2013 · The purpose of the Spatial Tools for the Analysis of River Systems ( STARS) toolset is to generate and format the spatial information needed to fit spatial statistical models. It is used in conjunction with the Functional Linkage of Waterbasins and Streams ( FLoWS) geoprocessing toolbox (see freebies below) for ArcGIS v 9.3.

Web1 Oct 2024 · Stream power index (SPI) SPI, which estimates the erosive power of surface runoff, encompasses slope degree and catchment area (Burrough and McDonnell, 1998), both of which influence flood occurrence (Khosravi et al., 2024). SPI is a major factor controlling channel widening and thereby influences flooding (Righini et al., 2024).
Web20 Mar 2024 · The Stream Length-Gradient Index (SL index) is a parameter that is frequently used to highlight the presence of anomalies in areas of intense fluvial erosion, as it is strictly related to the stream power. The SL index can be influenced by both lithological contrasts and tectonics (Merrits and Hesterberg 1994; Keller and Pinter 1996 ). WebThe Stream Link tool allows you to assign unique values to each of the links in a raster linear network. This is most useful as input to the Watershed tool to quickly create watersheds based on stream junctions. It can also be useful for attaching related attribute information to individual segments of a stream. Vectorizing a raster stream network
