STUDY ON THE DEPENDENCE OF THE CONDITION OF DRAINAGE SYSTEMS ON ROAD FUNDING

Abstract

An analysis of the scientific literature has shown that the technical condition and operational efficiency of irrigation and drainage systems are determined by a complex of external and internal factors having an impact: climatic, in other words external ones, uncontrollable factors affecting the technical condition of drainage systems, as well as technical and operational factors, meaning the internal ones, affecting the technical condition and operation of drainage systems. It is hypothesized that the dependence of the condition of drainage systems on road funding can be assessed. Thus, the aim of the study is to research the dependence of the condition of drainage systems on road funding. To achieve the goal, we have employed such research methods as analysis of scientific literature, induction, deduction, abstraction, multicriteria analysis, correlation, regression, Granger causality test. The performed correlation analysis suggests the existence of a strong significant relationship between the costs allocated for drainage systems, drainage area and the cost of roads. It should be noted that there is a negative correlation between the costs allocated for drainage systems and the cost of roads, which means that the higher the funding for drainage systems, the lower the funding for roads. The performed Granger test confirmed that the costs for roads affected the amount of costs for drainage systems in addition to the size of the drainage system, the overall condition of ditches, embankments and other hydraulic systems. The Granger causality test denied the existence of correlation between the precipitation and the condition of the drainage system as well as the funding allocated for this purpose.
