Landslides within the Kosñipata Valley in Peru were manually mapped over a 25-year period from 1988 to 2012 using Landsat 5 (Landsat Thematic Mapper) and Landsat 7 (Landsat Enhanced Thematic Mapper Plus) satellite images. The landslide inventory was produced by manually mapping landslide scars and their deposits in ArcGIS and by verifying via ground truthing of scars in the field. Mapping involved visually comparing images from one year to the next, specifically evaluating contrasting colour changes that suggest a landslide had occurred. The landslide areas visible via spectral contrast in the Landsat images include regions of failure, run-out areas, and deposits. Pan-sharpened high-resolution Quickbird and Worldview images were used to define the landslide boundaries.

Topographic shadow produced by hillslopes covered a minimum of 21% of the study area (35 km2 out of 185 km2), predominantly on southwest-facing slopes was consistently present between images. Landslides that fell within these shadow areas were not visible. Any landslides that were partially mapped underneath the Landsat topographic shadow were removed (see Figure 2a in Clark et al. 2016).

Landslide rates (Rls, %yr/1) calculated by 1 km2 grid cell in Figure 2b from Clark et al. (2016). In the table landslide rates appear as L_occurrence.

Hillslope turnover (tls, yr) rates calculated as the time for landslides, at the current measured rate (Rls), to impact 100% of each cell area in Figure 2c from Clark et al. (2016). In the table landslide derived hillslope turnover labelled as L_turnover.

Topographic shadow (http://www.hydroshare.org/resource/bdb9c4b4788d4141845947c81e5cceba) was removed from mapped landslides (http://dx.doi.org/10.4211/hs.90487bcf16e44c62a677ae33ef95e968) and then landslide rates were determined for a 1km2 grid.

Sheet 1: Discharge measurements at the San Pedro gauging station (1360 m.a.s.l.), along the Kosñipata River, in the Andes of Peru. The Kosñipata River at the San Pedro gauging station drains an area of 164.4 km2. Field measurements consisted of river height, flow velocity, and cross-sectional area, which together allowed us to estimate discharge and runoff over the study period. River stage height was measured from January 2010 to February 2011 using a river logger (GlobalWater WL16 Data Logger, range 0–9 m), recording river level every 15 min. The instantaneous discharge associated with each height measurement was calculated based on calibrated stage–discharge relationships. The Kosñipata River discharge at San Pedro was measured through a complete water year, with a 31-day gap partly in July and August (during low flow) that was covered by three manual measurements and the gap was filled using linear interpolation.

Sheet 2: Weekly to monthly discharge measurements at the Wayqecha gauging station (2250 m.a.s.l), along the Kosñipata River, in the Andes of Peru. The Wayqecha sub-catchment a nested catchment upstream of the San Pedro gauging station. It encompasses the headwaters of the Kosñipata River, draining an area of 48.5 km2 (See the supplementary information in Clark et al. 2014). Locations of the San Pedro and Wayqecha gauging stations are provided as GIS coverages in a companion dataset.
