HYDRAULIC CONDUCTIVITY OF PEATLAND WITH BOUWER AND RICE (1976) One TEST WELL

Abstract

This research aims at finding the hydraulic conductivity of the peatland on the location of canal blocking at the Bukit Tunggal subdistrict Jl. Cilik Riwut Km.13 Palangka Raya. It has been known that the hydraulic conductivity of the peatland is different from the ones from mineral soil. Peat soil consists of organic materials with high concentration which come from degradation of plants, in submerged and anaerobic conditions. In this research a well is built with 0,2m, 0,4m, 0,6m dan 0,7m deep in which the hydraulic conductivity will be calculated for each depth. The results shows that the hydraulic conductivity values are 7,823 x 10-7 ms-1, 6,3890 x 10-7 ms-1, 5,698 x 10-6 ms-1, dan 1,717 x 10-7 ms-1, respectively. These results are in accordance with the passed research in hydraulic conductivity values. Therefore, it can be concluded that the value of hydraulic conductivity is getting smaller when the depth of soil is increasing. It is because the maturity level of peat is different in different depth. More depth means denser the peat is. Therefore, lesser K value is found in deeper peat with lesser porosity.
