Abstract:In the field of water engineering it is very important to develop hydrological models to be able to predict the effect of changes in water flows. An important parameter in such a model is the hydraulic conductivity which is affected by many factors. The purpose of this thesis was to develop a pedotransfer function (PTF) to predict the hydraulic conductivity considering different land use types for the Bogowonto river basin, central Java. This PTF should describe the relationship between the hydraulic conductivity and the slope. The data have been collected at Sumbing Mountain in the north of the river basin. The hydraulic conductivity and slope were measured at 153 point on different plots. Three pinus forest, three acacia forest, three puspa forest and eight agriculture plots were investigated. A significant difference between agriculture and all forest types was found. The hydraulic conductivity was higher on agricultural sites, which is different from the results found in other studies. The top layer was very loose at the agricultural sides which might have caused the difference. However, more research should be done before any conclusions can be drawn. A very weak relationship between slope and hydraulic conductivity was found on forest, so it is recommended to use the mean of the obtained values as predictor in hydrological models. A linear relationship has been found between the hydraulic conductivity and the slope on agricultural sites.
