How do Weather Reach Receivers deal with excessive rain?
Rainfall amount and intensities can vary widely. A heavy, hard pounding down pour may be prone to run-off, whereas a gentle rain will soak into the ground. Heavy accumulations may soak well below the roots, and would no longer be available to the plants. To restrict the amount of rain recognized by the system two effective rainfall limits can be programmed. 1. Maximum Hourly Rain – Rain that falls faster than the soil can absorb may become run-off and may not be available to the plants. Enter the maximum amount of rain that should be accepted each hour in the ET balance. 2. Extra Rain A (or B) – Heavy rainfall may percolate below the root zone making it unavailable to the plants. Enter the number of inches of extra rain that the soil can hold beyond the ET Threshold. The value could be approximately 50% of the ET Threshold. This value controls the maximum amount of extra rain allowed in the ET balance. As rainfall amounts accumulate the ET Balance can go below zero and become a negativ
