Thermal and Chemical Responses of Karst Springs to Forcings at Multiple Time Scales
Responses of springs to precipitation depend onfactors such as climate,lithology,geologic structure,relief,and land use/land cover(LU/LC).Numerousstudies since the 1970s have documented that watertemperature(Tw) and chemistry in karst springs can varyat both storm-event and seasonal time scales.Infiltrationof dilute meteoric water,either focused throughdepressions(sinkholes) or diffuse through soil,displaceswater within fractures and conduits.Springs commonlyrespond to storms by an initial increase in discharge(Q),reflecting the relatively rapid propagation of a pressurepulse,followed by a decrease in specific conductance(SC) and a decrease or increase in Tw,depending uponthe contrast between air temperature(Ta) and Tw.Atlonger time scales,springs can exhibit flat,oscillatory,orerratic Tw patterns,depending upon the effectiveness ofheat exchange between water and the matrix.
