Description

Six environmental variables are represented as raster maps, and they are used in conjunction with locations of downed trees to inform the variable importance and relationships derived from results of the Maxent ML approach. These variables are processed as ESRI ASCII raster maps (*.asc), and input into the Maxent Model (Phillips et al. 2006). Four environmental variables (elevation, generalized slope, Euclidean Distance From River [EDFR], Inundation Probability) are raster maps that have a resolution (1.0m) and pixel locations coincident to the topography raster map that is input into HEC-RAS and featured in Castillo et al. (under review). Two classified variables (vegetation community, soil type) are informed by data form Ecological Mapping Systems of Texas (Elliott et.al., 2014), but transformed rasters with the same spatial information as those of the four environmental variables

Derived from resampled elevation values at a resolution of 20m using bilinear interpolation. Then, we use the Zevenbergen and Thorne (1987) slope approach in QGIS Desktop 3.4 to calculate slope values as degrees with a resolution of 20m. The raster map is then upsampled back to 1.0m with nearest neighbor interpolation to preserve image fidelity and align with other raster maps. Only those slope values within the model evaluation domain are used.

Calculated inundation probability within the Mission River Floodplain. Inundation probability was based on mean daily discharge record (1939-2016) using inundation extents from Castillo et.al. (under review) as indexes. All indices (as raster maps of inundation extent) are sorted by their corresponding discharge values and placed throughout the flow record. Each index is then weighted by proportion of flows that occur between them. The summation of these flows result in the inundation probability. Only those inundation probabilities within the model evaluation domain are used.

Raster maps representing soil type is derived from polygon geometries that represent patches from the Ecological Modeling Systems of Texas (Elliott et.al. 2014). Each patch is assigned a soil type classification are based on the EcoName fields within this dataset, respectively. Only soil type patches within the model evaluation domain are used.

Raster map representing vegetation community is derived from polygon geometries that represent patches from the Ecological Modeling Systems of Texas (Elliott et.al. 2014). Each patch is assigned a vegetation community classification is based on the CommonName fields within this dataset, respectively. Only vegetation community and soil type patches within the model evaluation domain are used.
