Pemodelan Neraca Air Berbasis Data Run-Off Untuk Pengendalian Fluktuasi Water Table Ekosistem Gambut Di Taman Nasional Zamrud (TNZ) Kabupaten Siak

---

Modeling can be used in many aspects, including for peatland water balances
through symbolic models with mathematical calculations and analog models in
imitating the original properties and characteristics of peatlands. Climatic conditions,
run-off, and inflow-outflow discharges of the area are water balance parameters.
Water balance is the main key for peatland water management, which is obtained when
the inflow-outflow discharges of the area have same value, and needed to control the
fluctuations of water table depth (WTD), in order to prevent the excessive deficit in dry
season or surplus in the rainy season. Taman Nasional Zamrud (TNZ) in Siak Regency
is an example of peatland ecosystem that requires controlling WTD fluctuations. The
average value in the dry season reaches -96cm, and in the rainy season reaches 20-
150cm above ground level. This condition has an impact to the quality of the peatland
that needs to be kept moist, and also to the quality of the waterways which affects the
socio-economic life of local settlers. Through this research, water balance modeling
based on run-off data (peak discharge/Qp) which is calculated using the rational
method, then compared with the instantaneous discharge (Qx) of inflow-outflow area.
The results showed that the current Qx inflow (20.59 m3/s) and Qx outflow (18.59 m3/s)
of TNZ were unbalanced, with Qp is 19.67 m3/s. It is necessary to adjust the wet crosssectional
area (A) at the observation point, so that Qx is equal, without being dispersed
into around waterways area. It is recommended to use canal blocking with sluice gates
in each canal (I-IV) with the opening and closing principle according to WTD
conditions in the surrounding area. In addition, normalize the Sungai Air Sejuk I and
II is required, so that the outflow returns to the Danau Bawah (not directly to the
Sungai Rawa via Canal I), with cleaning the aquatic plants that covers it. This action
is part of the area's water management that needs to be strengthened through policies
about the treatment of waterways. With an equal water balance, fluctuations in WTD
will be controlled and the sustainability of TNZ's peatland ecosystem can be
maintained.
