Rainwater Harvesting Calculators

Texas A&M AgriLife Extension publishes two calculators to aid in designing rainwater collection systems:


SunCalc is a little app that shows sun movement and sunlight phases during the given day at the given location.

You can see sun positions at sunrise, specified time and sunset. The thin orange curve is the current sun trajectory, and the yellow area around is the variation of sun trajectories during the year. The closer a point is to the center, the higher is the sun above the horizon. The colors on the time slider above show sunlight coverage during the day.

a great tool that may be useful: http://websoilsurvey.nrcs.usda.gov/app/. You can learn a great deal about the soil at specific locations *before* you take soil samples (or not) because the NRCS may have already sampled the soil for you. They've pretty much mapped the whole country.
