Influence of Plantation Establishment on Discharge Characteristics in a Small Catchment of Tropical Forest

Abstract

A study was conducted on the impact of forest clearance on discharge from newly established Hopea odorata plantations catchment (14.4 ha). The stands were two years old when this study commenced in year 2006 and the data collection was carried out for two years. The forested catchment (C3) was clear-cut during the preparation of the forest plantation and catchment C1 was left undisturbed. Discharge and rainfall were measured continuously for two years. The discharge measured from years 1997 to 2003 was used also to determine the water yield before and after forest clear-cut. This study showed that the plantation catchment is more responsive to storm with higher total water yield than in the forested catchment. The effect of forest clear cutting to discharge was clearly shown by the increment in the amount following the clear-cut activities and time taken for the recovery of the discharge back to its original state was almost three years. The peak discharge in C3 also was affected in which the biggest change was obtained during the forest clear-cutting period compared with during calibration and after clearing periods. This study is useful as basis for improving the existing guidelines on forest plantation establishment.

Peak flow responses to strip thinning in a nested, forested headwater catchment

“…Over the past few decades, debate has been ongoing on the effects of forest harvesting on peak flow (Rothacher, ; Jones and Grant, ; Hudson, ; Guillemette et al ., ; Dung et al ., ; Kuraś et al ., ; Green and Alila, ; Shamsuddin et al ., ). Previous studies on peak flow responses to forest harvesting have been contradictory because of variation in controllable factors (i.e.…”

PENGARUH PEMBANGUNAN HUTAN TANAMAN TERHADAP TATA AIR (STUDI SIMULASI DI DAS CITANDUY HULU) (Effect of Plantation Forest Development on Water System, A Simulation study in Upper Citanduy Watershed)

“…Pembangunan hutan (termasuk hutan tanaman) pada skala luas berpeluang menimbulkan dampak perubahan lingkungan khususnya sumberdaya air (Stanturf, Palik, & Dumroese, 2014). Hutan tanaman dengan tegakan yang sejenis (monokultur) akan memberikan respons yang berbeda terhadap hasil air pada suatu kawasan (Lisnawati, 2012;Mcguire & Likens, 2011;Shamsuddin, Yusop, & Noguchi, 2014). Beberapa hasil penelitian menunjukkan bahwa vegetasi hutan sejenis misalnya Pinus sp.…”

HASIL AIR HUTAN JATI PADA DUA SUB DAERAH ALIRAN SUNGAI DENGAN LUAS BERBEDA (Water yield of Teak Forest at two different catchment sizes)

“…Aliran dasar dan aliran langsung tersebut merupakan komponen hidrograf aliran. Tata air termasuk hasil air suatu DAS dipengaruhi oleh faktor pengelolaan lahan, dalam hal ini jenis penutupan atau penggunaan lahan yang menentukan besar dan distribusi hasil air (Krishnaswamy et al, 2013;Muñoz-Villers & McDonnell, 2013;Shamsuddin, Yusop, & Noguchi, 2014). Selain itu juga dipengaruhi oleh faktorfaktor alami seperti formasi geologi (Stoelzle, Stahl, Morhard, & Weiler, 2014;Vannier, Braud, & Anquetin, 2014), geomorfologi dan jenis tanah (Ayalew, Krajewski, & Mantilla, 2014;Geris, Tetzlaff, McDonnell, & Soulsby, 2015), dan input hujan (Dixon & Earls, 2012;Kretzschmar, Tych, & Chappell, 2014;Peleg, Shamir, Georgakakos, & Morin, 2015).…”
