these are generated with one saga command. Need to review as some of these are needed for the production of the desired layer where others the multiple outputs are desired.

slope_aspect_curve covers: slope, aspect, gencurve, totcurve tca includes: flowlength4 Distance2Water hdist, vdist Distance2Water2 hdistnob, vdistnob MultiResFlatness mrvbf, mrrtf MultiResFlatness2 mrvbf2, mrrtf2 MultiResFlatness3 mrvbf5, mrrtf5 Openness open_pos, open_neg RidgeValley val_depth, rid_level MRN mnr_area, mnr_mheight, mnr FlowAccumulation flow_accum_ft, MeanOvCatch, AccumMaterial, FlowAccumulation3 flow_accum_td, MeanOvCatchTD, AccumMaterialTD, FlowPathLenTD SolarRad direinso, diffinso SWI CatchmentArea, CatchmentSlope, ModCatchmentArea RelPosition slope_height, ValleyDepth, norm_height, stand_height, ms_position SlopeCurvatures local_curv, upslope_curv, local_upslope_curv, down_curv, local_downslope_curv

Questions to discuss with Gen

dem_preproc -- generated but not used for anything else

Overland distance to water -- two versions ... minor differences. Which one to keep? MRVBF 3 versions Distance to water 2 versions Flow Accumulation - 3 versions

Grossnickle fall plant had best shoot and root development but highest drought risk on drier sites.
