ANALYSIS OF THE INFLUENCE OF CHANNELS DISTANCE ON WATER BALANCE CALCULATIONS IN THE LIANG ANGGANG PROTECTED FOREST AREA BLOCK 1
Abstract
Peatland is an ecosystem that easily catches fire when dry. The highest number of forest fires was found in Banjar Regency, Banjar Regency, and Tapin Regency. One of the factors causing peatland fires in the Liang Anggang Protected Forest, apart from human activity, is the occurrence of drought, where more water is lost than water that enters the land. This study aims to analyze the water balance with the influence of the drought index on peatlands that are fibers and have canals based on the equation in Thompson's study (2014). The data used in the water balance research are monthly rainfall data, and monthly temperature data from 2000 to 2021 obtained from the Class II Meteorological Station Syamsuddin Noor Banjarmasin, then forest intercept is 16.4% based on research from Vernimmen (2007), calculations evapotranspiration (ET0), and storage changes in the unsaturated zone (Δϴ) with the modified Keech-Byram Drought Index value approach with the condition of the physical properties of fibers peat soil. The highest rainfall occurred in January 2021, 898.7 mm/month. The maximum average evapotranspiration (ET0) occurs in February, with a value of 100.3 mm/month. Based on the calculation of the water balance in the Liang Anggang Protected Forest Block 1, there was a water deficit from July to October, with the peak of the water deficit occurring in September, which was 65.6 mm/month and the peak of the water surplus in February, of 211.8 mm/month.
