Abstract

Hydrologic cycle in the Liz catchment is described with an anomaly in the vegetation seasons 1992–1996. Experimental catchment Liz is located in the Šumava Mts. in the Czech Republic. The fully forested watershed is covered by mature spruce forest, and its basic characteristics are as follows: drainage area 0.99 km2, mean discharge 0.01m3 s-1, runoff coefficient 0.38, mean annual air temperature 6.30 oC, average slope 17 %, basin length 1.45 km, water course length 1.43 km, elevation 828–1074 m a.s.l., precipitation sum 851 mm year-1, and runoff depth 324 mm year-1. Air temperature, precipitation, global radiation, and discharge in the closing profile are measured in the catchment. It is characteristic for hydrologic cycle in the catchment that the share of seasonal sums of both the global radiation and temperature was nearly constant in 1983–2000. However, the seasonal sums of both the global radiation and temperature were changed considerably in 1983–2000. Similarly, the share of seasonal sums of both the rainfall and runoff was nearly constant in 1983–1991 and 1997–1999. An anomalous course of climate was registered in 1992–1996, manifested by a deviation on the double mass curve of the seasonal sums of rainfall and runoff. Stabilised elsewhere, the ratio of rainfall and runoff is changed during the vegetation seasons 1992–1996. Starting from the 1997 season, this ratio has obtained the value held before 1992. The reason of the 1992–1996 anomaly of hydrologic cycle in the experimental catchment had to be significant external phenomenon, most likely explosion of the Mount Pinatubo volcano in Philippines on June 15, 1991.
