Geological Characteristics and Density of the Una Water System as a Factor of Spatial Planning, B&H
Geological structure has a significant effect on maintenance of rainwater on surface and its absorption into the underground. The depth of erosion processes and cutting of river valleys depend of it. Geological factors play an important role in the movement of groundwater. They determine the conditions of formation of groundwater, its position and speed of movement, depth of hydrological insulators and character of hydrological collector. Among other things, hydrogeological relations affect the density of the water system. Geological structure may be a limiting factor when it comes to planning and determining the purpose of the space, and as such, it largely affects the functionality of spatial planning. The highest population density in the area of Una basin is on those parts which are mainly consisted of watertight rocks with higher density of water system.
