Description of the biophysical characteristic and relation with discharge of Je'ne Rakikang Catchment Area

Abstract

This study aims (1) to determine the biophysical characteristics and discharge on Je'ne Rakikang Catchment Area, (2) the relationship between the biophysical characteristics and discharge on Jene Rakikang Catchment Area. This research was conducted at Jene Rakikang Catchment Area. The data were collected in the form of primary and secondary data. Primary data were determined by measuring the discharge and precipitation, during 31 days of observation and secondary data collected from government agencies or related institutions such as land cover collected the data from the Institute for Balai Pemantapan Kawasan Hutan Wil. VII Makassar, rainfall data from the Global weather (2004-2013), geological data from Ujung Pandang GRDC Sheets of 1982, the data from Aster DEM slope, soil type data from RePP Prot 1987 and the data obtained from the calculation as well as visually. The data were analyzed using the quantitative descriptive method. The results showed that the dishcarge fluctuations of Je'ne Rakikang Catchment Area very varied. Biophysical characteristics of the Je'ne Rakikang Catchment Area consist of geology, topography, soil type, orientation, area, shape, draignase density, stream gradient, flow pattern, land cover and rainfall could potentially influence the behavior of discharge. The different of biophysical characteristics of Jene Rakikang Catchment Area provide a response to discharge in the event of rain with short time. ne Rakikang Catchment Area very varied.
