Hawaiian Islands excess rainfall conditions under current (2002-2012) and future (2090-2099) climate scenarios
One of the determinants of runoff is the occurrence of excess rainfall events where rainfall rates exceed the infiltration capacity of soils. To help understand runoff risks, we calculated the probability of excess rainfall events across the Hawaiian landscape by comparing the probability distributions of projected rainfall frequency and land cover-specific infiltration capacity. We characterized soil infiltration capacity based on different land cover types (bare soil, grasses, and woody vegetation) and compared them to the frequency of large rainfall events under current and future (pseudo-global warming) climate scenarios. This simple analysis allowed us to map the potential risk of excess rainfall across the main Hawaiian Islands. Here we provide rasters that contain the probability of rainfall exceeding infiltration capacity in each grid cell at 90 m. We have included rasters of excess rainfall probabilities for current (2002-2012) and future (2090-2099) scenarios as well as by each individual land cover class considered.

Estimating the impact of climate and vegetation changes on runoff risk across the Hawaiian landscape
In Hawai’i, ecosystem conservation practitioners are increasingly considering the potential ecohydrological benefits from applied conservation action to mitigate the degrading impacts of runoff on native and restored ecosystems. One determinant of runoff is excess rainfall events where rainfall rates exceed the infiltration capacity of soils. To help understand runoff risks, we calculated the probAuthorsLucas Fortini, Lauren R. Kaiser, Kimberlie Perkins, Lulin Xue, Yaping Wang - Connect
