Geocache Description:

Karst topography is a landscape shaped by the dissolution of a layer or layers of soluble bedrock, usually carbonate rock such as limestone or dolomite.

Due to subterranean drainage, there may be very limited surface water, even to the absence of all rivers and lakes. Many karst regions display distinctive surface features, with sinkholes or dolines being the most common. However, distinctive karst surface features may be completely absent where the soluble rock is mantled, such as by glacial debris, or confined by a superimposed non-soluble rock strata. Some karst regions include thousands of caves, even though evidence of caves that are big enough for human exploration is not a required characteristic of karst.

The Vrbas is a major river in western Bosnia and Herzegovina. It is a right tributary of the river Sava. The town of Banja Luka is located on the river banks. It lent its name to one of the provinces (banovinas) of the Kingdom of Yugoslavia, the Vrbas Banovina.

The Vrbas river appears at the southern slope of the Vranica mountain and it drains central part of the northern slopes of the Dinaric mountain massif. It empties into the Sava river at around 90 meters above the sea level. Total length of the main watercourse is around 235 km. Between Jajce and Banja Luka, the hydroelectric dams Bocac (Hidroelektrana Bocac) with a 66 meter high Vrbas the wall stretches for more than 20 kilometers to a reservoir (Lake Bocac). The power plant is in operation since 1982 and has a capacity of 110 MW on. Average annual rainfall is around 800 l/m2 at the mouth of the Vrbas to the Sava river and up to 1500 l/m2 in the southern part of the basin. Characteristic mean flow is around 34,6 l/s/km2 Maximum rainfall occurs in the southern parts of the Vrbas basin in the late autumn and winter months, with minimum quantities in summer, whereas the northern parts of the basin receive the largest quantities of rain during the summer months (June-July), with the maximum in November and December.
The most important tributaries are Pliva, Ugar, Crna Rijeka and Vrbanja which are located in the middle part of the basin. "Vrbas" means "willow" in Bosnian/Croatian/Serbian and a number of weeping willow trees adorn the river banks in Banja Luka.
