Samarinda travel vocabulary in English and Chinese: 100 distinctive words for Mahakam freshwater-dolphin monitoring, floodplain limnology, river shipping, Samarinda sarong production and resilient riverfront design.
Samarinda is a river city in the strongest possible sense. The Mahakam carries wildlife, freight, neighbourhood life and public space through the same urban corridor. This guide therefore treats the river as ecology, transport and infrastructure at once.

How to use this Samarinda vocabulary guide
The English respellings are approximate. Pinyin belongs to the Chinese translation. This page keeps away from Banjarmasin’s floating-house and market vocabulary by giving Samarinda a Mahakam-science, transport and textile-production role.
- Pesut and acoustic monitoring: words 1–30.
- Mahakam limnology: words 31–40.
- River shipping: words 41–60.

Samarinda and the Mahakam notes
The Mahakam is East Kalimantan’s great river corridor
Indonesia Travel describes the Mahakam as the lifeblood of East Kalimantan, extending for more than 900 kilometres and linking inland landscapes with the Makassar Strait. Samarinda sits directly on this river corridor. Read the official Mahakam River guide.
The Mahakam supports an unusual freshwater dolphin population
Indonesia Travel identifies Pesut Mahakam as the Irrawaddy dolphin, Orcaella brevirostris, using deeper and calmer reaches of the river system. Monitoring therefore depends on repeated observation, acoustics and habitat data rather than one lucky sighting.
Floodplain lakes belong to the same river system
The Mahakam’s middle reaches include connected lakes and floodplains whose water exchange changes strongly with season. Dolphin habitat, fish movement and human river use all respond to that hydrological pulse.
Samarinda’s river is also a freight corridor
Large barges, towboats and passenger craft share the same water with small local boats. Vocabulary such as tow speed, bridge clearance and meeting reach helps explain why river navigation is a coordination problem.
Samarinda sarong is a recognised local craft
Indonesia Travel describes Sarung Tenun Samarinda as a longstanding East Kalimantan textile heritage made manually by local artisans and known for geometric motifs and bright colour. Read the official Samarinda sarong feature.
A riverfront must move with changing water
Floating docks, gauge boards and flood-tolerant public spaces turn water-level variability into an urban-design problem rather than treating the river as static scenery.
Six bilingual conversations for Samarinda
1. Listen before seeing
A: We cannot see the dolphin. Does that mean it left?
B: Not necessarily. Passive acoustic monitoring may still detect click trains.
中文：甲：看不到江豚，就表示它离开了吗？
乙：不一定，被动声学监测可能仍能检测到点击序列。
2. Separate sightings from probability
A: We saw more dolphins today. Is abundance definitely higher?
B: Compare encounter probability, effort and conditions before concluding.
中文：甲：今天看到更多江豚，就一定表示数量增加吗？
乙：要先比较遭遇概率、调查投入和环境条件。
3. Read the floodplain
A: Why does a lake matter to a river dolphin?
B: Seasonal river-lake exchange can affect prey-fish movement and habitat.
中文：甲：湖泊为什么和江豚有关？
乙：季节性河湖交换会影响猎物鱼移动和栖息地。
4. Read a convoy
A: Why can’t the barge turn like a small boat?
B: A push-tow convoy has much greater length and turning requirements.
中文：甲：驳船为什么不能像小船那样快速转弯？
乙：顶推船队长度更大，需要更大转向空间。
5. Read a textile
A: Is a warp stripe the same as a printed stripe?
B: No. It is built into the cloth through coloured warp yarns.
中文：甲：经向条纹和印花条纹一样吗？
乙：不一样，经向条纹是通过有色经纱直接织出来的。
6. Read the riverfront
A: Why use a floating dock?
B: It moves with water level and can reduce large changes in boarding height.
中文：甲：为什么使用浮动码头？
乙：它会随水位升降，减少登船高度变化。
Six meaning distinctions
A click train and a visual sighting are different data types
One records sound; the other records direct visual observation.
Floodplain connectivity is seasonal
Habitats that are separate in low water may reconnect during flood pulses.
Towboat and deck barge have different roles
The towboat provides propulsion or control; the deck barge carries cargo.
Yarn count and thread twist measure different properties
Yarn count describes fineness; twist describes fibre rotation within yarn.
Warp stripe and weft stripe run in different structural directions
Warp stripes follow the lengthwise yarn system; weft stripes cross it.
River level and boarding level are related but not identical
Dock geometry and gangway position translate changing water level into actual boarding conditions.
Build a Samarinda sentence with the Fencing Method
- The dolphin surfaced.
- A known dorsal-fin notch matched the catalogue.
- A hydrophone recorded clicks during the same encounter.
- The record was added to the boat-based transect database.
- The sentence now turns one sighting into repeatable monitoring evidence.
A short Samarinda writing model
Our fictional Samarinda morning began with a sound we could not see. A click train appeared on the acoustic display before a pesut surfaced beside the deep channel. Farther downstream, a push-tow convoy changed the scale of the river from habitat to transport corridor. At a weaving workshop, warp stripes and yarn counts made another kind of pattern visible. By sunset on Tepian Mahakam, the river had become one joined system of ecology, logistics, craft and public space.
Practice
- Design a dolphin sighting sheet.
- Explain acoustic masking in plain English.
- Draw seasonal river-lake connectivity.
- Label a push-tow convoy.
- Compare warp and weft stripes.
- Design a riverfront with a floating dock and gauge board.

Frequently asked questions
Does the Mahakam flow through Samarinda?
Yes. Indonesia Travel describes Samarinda as a practical starting point for exploring the Mahakam.
Is Pesut Mahakam a freshwater dolphin?
It is an Irrawaddy dolphin population living within the Mahakam river system.
Does one sighting prove population growth?
No. Survey effort, detectability and repeated monitoring matter.
