Measuring infiltration capacity in the field

Posted on March 15, 2020 by Anne Jefferson

Infiltration capacity is measured by devices that let water soak into the ground until a steady rate is reached and then some math. This post focuses on the field work and skips the math. Continue reading →

Measuring evapotranspiration components

Posted on March 12, 2020 by Anne Jefferson

Evapotranspiration is often said to be the most difficult water balance component to directly measure. When water goes from liquid to vapor, you can’t exactly catch it in a bucket or measure flow in a channel. In my Watershed Hydrology … Continue reading →

Measuring actual evapotranspiration with weighing lysimeters

Posted on March 12, 2020 by Anne Jefferson

Weighing lysimeters are one of the very best ways of measuring the actual evapotranspiration from a small area of land, because they use mass balance (i.e., changing weight) to give us the combined total of plant transpiration, soil evaporation, and interception losses over time. Continue reading →

Measuring precipitation: radar and satellite based measurements

Posted on March 11, 2020 by Anne Jefferson

…the vexing problem is figuring out how well that point measurement represents a broader area of interest. So in this post, I want to focus on technologies that look to the sky to provide data on the intensity of precipitation occurring over broader areas. Continue reading →
