Stream Order for drainage to streams in the Ipswich or Parker River Network - ASCII Raster File
This datalayer is a gridded data set that identifies for each pixel the stream order that drainage from the pixel initially enters into the river network. The resolution is 120 m x 120 m. Based on the flow direction in: WAT-RGIS-120m-FlowDirection.asc. First order streams at the 120m resolution are equivalent to third order when calculated at the pixel level from the drainage direction grid (i.e. 3rd order pixels are equivalent to 1st order streams, 4th order pixels are second order streams, etc). Idenitify the distribution of inputs from land to streams of different sizes.

Local and landscape environmental variables from 86 Neotropical streams, Upper Paraná River basin, Brazil
<p>The dataset comprise environmental characterization for 86 streams in the Turvo-Grande and São José dos Dourados basins, Upper Paraná River basin, northwestern of São Paulo State, Brazil. We selected those streams considering the environmental gradient in the region (i.e., pasture-sugarcane transition). In each stream we quantified 31 local descriptors related with marginal vegetation (e.g., marginal grasses, roots, shrubs), water properties (e.g., water temperature, pH), instream structures (e.g., litter, wood debris), stream channel morphology (e.g., width, depth, flow), habitat composition and heterogeneity (e.g., mesohabitat, substrate composition). In addition, for each stream catchment (i.e., catchment area delimited upstream from the sampled stream reach), we measured 30 descriptors related with land-use composition and heterogeneity quantified through (i) the number of the land-use classes (i.e., richness), (ii) diversity of land-use classes (i.e., Shannon index), and (iii) the relative proportion of each land-use class. For a detailed description of how variables were obtained see Molina et al. (2017); Roa-Fuentes & Casatti (2017); Roa-Fuentes et al.
