Abstract
Mitigating the peat fire disasters in Indonesia during the dry season for more than 20 years (1997-2017) have obstructed by the limited accessibility of surface water resources (including water canals and rivers). Hence, there was a need to seek another opportunity to have access for the water for mitigating the peat fires from local shallow aquifer water resources. Various pumping tests have been conducted to explore the potential and characteristics of the shallow aquifer water for mitigating the peat fires in Riau, Indonesia. The groundwater transmission and storage (storativity) were tested using pump tests. The Cooper Jacob (a straight line) method had been applied to analyze the field data. This study has yielded the following results; the water transmissivity (T) was 1145.98 m2/day, water storage (S) coefficient was 1.09 x 10-3, and the deep depth of the shallow aquifer water (from the ground surface) was approximately 10 meter. Hence, this research identified that the potential shallow aquifer water produced from every single well in the surveyed area in Riau may reach 433.4 m3/day. The amount of this water was considered more than enough to extinguish 4 ha of peat fire occurrences.
Highlights
Accessibility of surface water for fire suppression measures in peatland areas in Sumatra and Kalimantan islands, Indonesia during the dry season has been relatively limited [1, 2]
The surface water resource for extinguishing the peat fires in Indonesia has been fetched from the water canals, river water, and ponds were relatively inadequate (Figure 1a)
Various efforts for extinguishing peat fires have been conducted by the Regional Disaster Management Agency (BPBD) a non-departmental government agency, fire brigades, community fire awareness (MPA), Maggala Agni, Armed Forces, Policies, and the local government departments have become less effective in the absence of water resources (Fig. 1b)
Summary
Accessibility of surface water for fire suppression measures in peatland areas in Sumatra and Kalimantan islands, Indonesia during the dry season has been relatively limited [1, 2]. The surface water resource for extinguishing the peat fires in Indonesia has been fetched from the water canals, river water, and ponds were relatively inadequate (Figure 1a). Various efforts for extinguishing peat fires have been conducted by the Regional Disaster Management Agency (BPBD) a non-departmental government agency, fire brigades, community fire awareness (MPA), Maggala Agni, Armed Forces, Policies, and the local government departments have become less effective in the absence of water resources (Fig. 1b). This paper explored an alternative water resource from the shallow aquifer groundwater resources to extinguish the peatland fires in Riau. Https://doi.org/10.10 51/matecconf /201927602001 coefficient (T) and groundwater storage coefficients (storativity, S). These two parameters can be used to estimate the potency of the groundwater availability. The research study was located at Desa Rantau Baru, Pangkalan Kerinci District, Pelalawan regency, Riau province, Indonesia at the coordinate 0°20'26.9"N 101°49'32.0"E (Fig. 2)
