Errata and Developments
Rainwater harvesting systems continue to evolve, especially the more we share and study techniques. Also, while every effort has been made to keep this book error free, any errors found will be immediately documented. These next-step evolutions and any errors found will be documented at http://appropedia.org/To_Catch_the_Rain/Errata.
Other Books, Research, and Calculators
Many great books and peer-reviewed journal articles cover rainwater harvesting. In order to stay up to date, these books are at http://www.appropedia.org/Rainwater_books. The articles are collected at http:// www.appropedia.org/Rainwater_catchment_literature_review. In addition, rainwater calculators are listed at http://www.appropedia.org/Ra inwater_calculators
Great places to look for climate data, especially precipitation data, include the United States Geological Survey (USGS), National Oceanic and Atmospheric Administration (NOAA), and Global Precipitation Climatology Centre (GPCC). More up-to-date climate data sets are listed at http://www.appropedia.org/Climate_data.
