Knowledge of soil hydraulic and thermal properties is essential for studies involving the combined effects of soil temperature and water input on water flow and redistribution processes under field conditions. The objective of this study was to estimate the parameters characterizing these properties from a transient water flow and heat transport field experiment. Real-time sensors built by the authors were used to monitor soil temperatures at depths of 40, 80, 120, and 160 cm during a 10-hour long ring infiltration experiment. Water temperatures and cumulative infiltration from a single infiltration ring were monitored simultaneously. The soil hydraulic parameters (the saturated water content θ s , empirical shape parameters α and n, and the saturated hydraulic conductivity Ks) and soil thermal conductivity parameters (coefficients b1 , b2 , and b3 in the thermal conductivity function) were estimated from cumulative infiltration and temperature measurements by inversely solving a two-dimensional water flow and heat transport using HYDRUS-2D. Three scenarios with a different, sequentially decreasing number of optimized parameters were considered. In scenario 1, seven parameters (θ s , Ks , α, n, b1 , b2 , and b3) were included in the inverse problem. The results indicated that this scenario does not provide a unique solution. In scenario 2, six parameters (Ks , α, n, b1 , b2 , and b3) were included in the inverse problem. The results showed that this scenario also results in a non-unique solution. Only scenario 3, in which five parameters (α, n, b1 , b2 , and b3) were included in the inverse problem, provided a unique solution. The simulated soil temperatures and cumulative infiltration during the ring infiltration experiment compared reasonably well with their corresponding observed values.
Partial compatibilism says that there are basically two kinds of freedom of the will: some free volitions cannot be determined, while others can. My methodological choice is to examine what as- sumptions will appear necessary if we want to take seriously—and make understandable—our ordinary moral life. Sometimes, typically when we feel guilty about a choice of ours, we are sure enough that we, at the considered moment, actually could have taken a different option. At other times, however, typically when we are aware of some unquestionable moral reasons for a certain choice, we may perceive our choice as voluntary and free in spite of the fact that it is, in the given situation, unthinkable for us to choose otherwise than we actually do (there are situations when responsible agents, because of their strong moral reasons/motives, cannot choose differently). The assumption that experiences of the first kind are not always mistaken excludes our world being deterministic. Yet free will and determinism go together in some of those possible worlds which contain only the second kind of free volitions. Partial compatibilism represents a ‘third way’ between standard compatibilism and incompatibilism, a way to solve that old dilemma.
