Influence of Forest Vegetation Fighting of Erosion in the Torrent Flow on the Mediterranean Part of Croatia     pdf     HR     EN 299
Summary: The Mediterranean area of the Republic of Croatia covers

15.389 km2. It is a typical karst area, where the soil erosion and its most excessive form — torrents — are a great problem. The greatest and the most difficult torrent problem is on the areas with unpassable soils (werfench, marls and flysch), which take great areas in the coastal part and in the flows of rivers. These areas are very erosive, especially if they are badly managed and without vegetation. Having thes reasons in mind, the Institute for the adriatic cultures and karst melioration in Split founded in the year 1971 the experimental plots Bp B2 and B; in the mouth of the torrent Suvava in Mud, on the inclination 28,8 with the recipients and the corresponding plant cover, with the cum to come to the original data about the important characteristics of the waiter soil erosion by modern methods. The flow of Suvava takes the area of 1.823 ha, with the length of the main flow of 10,1 km and the entire length of greater and smaller tributery streams — torrents of 20,8 km. Its form is protruded and it extends itself between 460 and 961 m above the sea level (Fig. 1). The climate of this area is submediterranean, with the average year rainfall of 1.329 mm. In Mud there are 92 rainy days on an average, and from that 18 erosive ones. In the geological sense, the flow is very different. There are formations of lower and middle trias, lias, iura and the quarter. On the trias we mainly find minerologic soils, on the limestones of iura thin brown soils and from the quarter there are smaller areas of terra rossa soils.

The greatest part of the flow area, in the vegetation sense, belongs to the community of Oak downy, and Hornbeam oriental. The forest of almost whole flow area was pushed back and its is found in different stadiums of degradations, from underbrush to bare ground.

This paper deals with the erosion processes on bare soil and on the soils under forest vegetation (Spanish broom, juniper). The research was done on the experimental plot Bsfor the period of 1973 — 1981, the the period when the plot was without vegetation (bare ground) and for the period of 1982 — 1993 when it was under vegetation.

The data of the surface flow off and soil loss are shown on the graph 1 and

2. The average year values of the surface flow off on the bare area are 11,6 mm (1.116,0 m\ha´), with the coefficient of flow away 0,076 and soil loss 191,571 g. m2 or 1,921. ha´, and on the area with the vegetative cover (Spartium junceum and Juniper us oxycedrus) the surface flow off is 8,3 mm (83,0 m3.ha~ ´) with the coefficient of flow away 0,0068 and the soil loss of only 0,309 g.m2 or 0,0031 t.hci1. The soil loss on the bare area 619,97 times larger than under the vegetative cover.
