Table 1. Synthesis of base flow and yield for the El Morro catchment. The location of sites is presented in Figure 2b. For each stream base flow mean, coefficient of variation of all observations and the proportional flow decline during the warmest season (December to April) compared to the rest of the year (May to November)  is indicated as “summer drop”. Segmented estimates are based on the subtraction of nested sections of the catchment. All base flow estimates are based on 17 sampling dates obtained between November 2017 and August 2020 except for archive data whose year and number of repeated measurements is presented in the table. For each sub catchment or segment the total length, corresponding to the linear extension of all continuous permanent streams feeding it is shown. Length of deposits and wetlands represents the extension of those streams intersecting those features without prominent incision (> 1 m). The maximum incision depth corresponds to present conditions. Catchment area and their associated base yield were defined according to a purely topographic rule following surface contributing areas to the sampling point and a geometric rule considering constant supply width of 2.6 and 12.5 km in the upper-mid and mid-lower catchment, respectively.

Table 2. Greenness trends derived from MODIS data for the El Morro catchment. Vegetation was classified in 2018. For each vegetation type mean NDVI across pixels was calculated each year and then mean and standard deviation across years were obtained. NDVI shifts are described based on the proportional change observed between the average values of each pixel in 2000-2010 and 2011-2020 and by identifying and selecting those which displayed significant long linear term trends (p<0.05).
