Abstract

This geographic sub-watershed is in Loa Janan, position 116°49′ EL–117°08′ EL and 0°34′ SL–0°45′ SL, with an extent of 644.2 km 2 that includes eight villages. Characteristics of rain in this area are included in the area class III (1,500–2,000 mm/year), with a bimodal or double wave rainfall model with C pattern. The highest rainfall period is in December and April, and the lowest rainfall in September and November. The sub-watershed has level Q (±9.8 %), or rainfall type A (very wet area with tropical wet vegetation), and an E1 agroclimate zone. Monthly water balance indicated that this area has a potential growing season available all year round (12 months), a water surplus for 8 months (478.8 mm/year), and a water deficit for about 3 months (44.5 mm/year).
