Seoul National University - Climate Change Impact Assessment for Hydrology Library (SNU-CAHL) is a collection of tools for climate change impact assessment in hydrology. The tool has three main goals:
Automation of hydrologic modelling in climate change scenarios.
Easily import and integrate climate data with hydrology data for multi-model analysis.
Provide the resources for informed decisions and conclusions through performance indexes.
This tool was made by the Research Group for Climate Change Adaptation in Water Resources at Seoul National University.
snucahl
package requires the hydromad package, which is a required dependency but is not available on CRAN. Install hydromad
with the following commands:
install.packages(c("zoo", "latticeExtra", "polynom", "car", "Hmisc","reshape")) install.packages("hydromad", repos = "http://hydromad.catchment.org")
snucahl
can be installed and loaded using the following commands:
library("hydromad") devtools::install_github("CCAWR/SNU-CAHL") library("snucahl")
SNU-CAHL package can be used in two different manner. One is the library portion, which contains the functions within R specific to SNU-CAHL. The other is the script/
folder which contains useful scripts used when running the full SNU-CAHL stack.
The test data supplied here are observed gauge datasets obtained from http://www.wamis.go.kr for the Yongdam Catchment in South Korea within the Geum River Basin (4001). The forecasted projections are from the Korea Meteorological Administration GCMs which were downscaled within CCAWR.
