That Froude number is a dimensionless numerical quantity used as an index to characterize the type of flow in a hydraulic structure that has the force of gravity (as the only force producing motion) in conjunction with the resisting force of inertia. it is the ratio of inertia forces to gravity forces, and is equal to the square of a characteristic velocity (mean, surface, or maximum velocity) of the system divided by the product of a characteristic linear dimension (e.g. diameter or depth) and the gravity constant, acceleration due to gravity, all of which are expressed in consistent units in order that the combinations will be dimensionless. the number is used in open-channel flow studies or where the free surface plays an essential role in influencing motion [1] such as in karst conduits that are not necessarily flowing at pipe-full conditions. see also chezy equation; manning equation; reynolds number.?

Investigations of the vegetation and soil in the dolinas of Mecsek mountains, South Hungary

Abstract:

The data of karst ecological study in Mecsek Mountain (South Hungary) can be compared by the analyses in Bükk Mountain and Aggtelek (North Hungary). The western part of Mecsek Mountain is rich in karst forms, the rock base being in strongly fissured Triassic limestone. From a morphometric point of view these dolines are significantly different from those in the karst areas of Bükk and Aggtelek; they are smaller, more shallow and funnel shaped. The amount of 700 mm precipitation per year and increased CO2 production of root systems play an essential role. Soil research studies also support the juvenility of these dolines. Dolines in the Orfü karst plateau are in a natural state, more or less free from anthropogenic influences; however, indirect effect can be shown by the fact that the soil pH is turning sour. This state close to its natural condition is of great value of the landscape, as nowadays it is an important task to conserve the natural conditions of the environment, especially in karst regions. The karst is a highly vulnerable natural system that reacts with great sensitivity to anthropogenic influences, so it requires increased protection; this is why it would be reasonable to include the Orfü karst region in conservation projects.
