KL E/ FEL DER Bright People. Right Solutiom by alternating periods of precipitation and sun. The response of the shallow probe to rainfall (1.6 inches in December) showed an increase in soil moisture. Precipitation events in the 2007/2008 water year elicited a corresponding change in moisture content at all three depths. February, April, October, and December were heavy rainfall months (greater than 0.75 inches per month) for the year. Nearly 3 inches of rain in February caused a rise in moisture content at all three depths, with the largest increase at the 1 -foot level and the smallest at the 3 -foot level. Rainfall in April (1.2 inches) caused a smaller Increase at the 2- and 3 -foot levels. A period of drying occurred during the summer, with the moisture content of the 1 -foot level and dropped below that of the 2- and 3 -foot depths. In water year 2008/2009, October rain (0.79 inches) caused a slight increase in moisture at the 1 -foot level, with the two deeper probes remaining unaffected. Heavier rains in December (1.63 inches) caused a rise in the 1- and 2 -foot sensors, but not the 3 -foot deep sensor. January was a heavy rainfall month with 5.25 inches. That represented over one-third of the yearly average for the area deposited during a 31 -day period. The moisture content continued to rise through May and then started a drying period during the summer. There was a data gap in 2008/2009 monitoring, March through April. The March through April download file was corrupted and could not be recovered. Water year 2009/2010 appears to follow a natural flow path as the 1 -foot probe is dryer than the two deeper probes following the summer season. Rainfall in October and November caused a rise in soil moisture at all depths at the beginning of water year 2009/2010. Soil moistures peaked in February and have slowly decreased through June. Rain in November 2009 caused the 1 -foot probe to read higher moisture concentrations. The 2- and 3 -foot probes were unaffected until heavy rains from January 2010 through the end of February, which appeared to provide enough pressure to travel through the soil profile. With time, the 3 -foot probe showed the most moisture due to water from the top layer moving deeper. As rainfall decreased and temperatures increased in June, soil moisture concentrations began to fall as the soil dried out. 47717.1 1/ST01 1 R193 Page 6 of 9 August 31, 2011 Copyright 2011 Kleinfelder
