In Karjanha
study area, the monitoring/observation well no 04 (TW-04), located at Gautari
Kuti - 8, is in the Gangetic Plain at
the Southern belt from Highway.
TW-04 swings
wildly between 1.4 m and 3.8 m in the May–July 2025 window, then collapses to a
near-flat ~1.3–1.5 m plateau for 10 months. The TW-04 thus finds a low
equilibrium — but at a lower absolute level and with less spring recovery. This
reflects the behavior of TW-04 as high early volatility, then structural low
plateau. The large May–June swings (2.6 →
3.6 →
2.4 →
3.0 →
3.8 m) across just 6–8
weeks are too large and rapid for natural aquifer fluctuation alone. They
almost certainly reflect alternating heavy pumping and recovery events — possibly irrigation
cycles — in a well with very
limited storage volume. This indicates that pre-monsoon oscillations are
diagnostically unusual, This chart shows the water level fluctuation revealing a
pattern of high levels in May - July 2025 followed by a decline and
stabilization through late 2025 until early 2026, with a modest recovery by May
2026. Further observations can be made as mentioned below:
·
Phase 1 (May–July 2025): Rapid swings of
up to 2.4 m within weeks — physically consistent with a low-storage aquifer
being repeatedly drawn down and allowed to recover between pumping sessions.
Irrigation demand likely driver. This reflects the pump-cycle volatility with
Strong peak indicating robust rainfall infiltration and aquifer recharge.
·
Phase 2 (Aug - Sept 2025): Despite a
July peak of 3.8 m (the highest reading in record), the well collapses to ~1.4
m within weeks. Classic "fast drain" behavior — the aquifer accepts
recharge rapidly but cannot retain it once pumping resumes. This indicates the
monsoon crash (decline) with levels drop reflecting aquifer depletion as
recharge slows and extraction continues.
·
Phase 3 (Sept 2025 – April 2026): Ten
months at ~1.3–1.5 m with almost no variation — an even flatter and longer
plateau than TW 03's 8-month stabilization. At this depth the well is under
chronic stress but not yet failing. Margin is very thin. This suggests a low
stable plateau during the dry season with water levels remaining relatively
stable, showing aquifer resilience despite reduced recharge.
·
Phase 4 (May 2026): A rise to ~1.8 m in
April and 2.3 m in May 2026. The recovery is proportionally similar to TW 3,
and the YoY deficit (~0.3 m) is the smallest of any Ward 8 well — suggesting
this aquifer has better recharge access than TW 1 or TW 2. This suggests a modest
spring uplift / recovery with gradual rise of water level to ~3 m reflecting
aquifer responsiveness to late winter/early spring recharge.
This tubewell
demonstrates a classic monsoon-driven cycle, but with slightly less amplitude.
The aquifer here is resilient, maintaining stability through dry months and
recovering predictably with seasonal recharge. TW-04 shows a balanced pattern
i.e. strong recharge, moderate depletion, and reliable recovery. This tubewell
is therefore dependable, with predictable seasonal variation, and anticipates
stress in Sep–Dec, but otherwise reliable year-round. This site
illustrates hydro-social resilience with seasonal vulnerability, reinforcing
the need for adaptive water-use strategies.
१२. गौतारी कुटीको ट्युबवेल - वडा
नं. ८, कर्जनहा
कर्जनहा
अध्ययन क्षेत्र अन्तर्गत गौतारी कुटी-८ मा अवस्थित अनुगमन/अवलोकन ट्युबवेल नम्बर ०४ (TW-04) राजमार्गबाट
दक्षिणतर्फको Gangetic Plain मा पर्दछ।
मे–जुलाई
२०२५ को अवधिमा TW-04 को जलस्तर
१.४ मिटर र ३.८ मिटरको बीचमा तीव्र रूपमा उतारचढाव हुन्छ (Swings wildly), र त्यसपछि लगातार १० महिनासम्म करिब १.३
देखि १.५ मिटरको लगभग समतल पठार (Flat plateau) मा संकुचित
हुन पुग्छ। यसरी TW-04 ले एक
न्यून सन्तुलन (Low equilibrium) फेला
पार्छ—तर तुलनात्मक रूपमा न्यून स्तरमा र वसन्त ऋतुको कम सुधारका साथ। यसले
सुरुवाती समयमा देखिने उच्च अस्थिरता र त्यसपछिको संरचनागत न्यून पठार (Structural low plateau) को चरित्रलाई प्रतिविम्बित गर्दछ। मात्र ६ देखि ८ हप्ताको छोटो अवधिमा
देखिएका मे–जुन महिनाका ठूला उतारचढावहरू (२.६→३.६→२.४→ ३.०→३.८ मिटर) केवल प्राकृतिक एक्विफर
परिवर्तनका कारण मात्र हुन नसक्ने गरी निकै ठूला र द्रुत छन्। यसले निश्चित रूपमा
अत्यन्तै सीमित भण्डारण क्षमता (Storage volume) भएको यस ट्युबवेलमा निरन्तर भइरहेको अत्यधिक पम्पिङ र त्यसपछिको सुधारका घटनाहरू—सम्भवतः
सिँचाइ चक्र (Irrigation cycles)—लाई
प्रतिविम्बित गर्दछ। यसले के संकेत गर्छ भने मनसुन पूर्वको यस्तो उतारचढाव
जलवैज्ञानिक निदानका दृष्टिकोणबाट असामान्य हो। यस रेखाचित्रले जलस्तरको
उतारचढावमा मे–जुलाई २०२५ मा उच्च स्तर, २०२५ को
अन्त्यतिर गिरावट, र सन् २०२६
को सुरुवातसम्म स्थिरता कायम भई मे २०२६ सम्ममा सामान्य सुधार भएको चक्र देखाउँछ।
यसका थप अवलोकनहरूलाई निम्नानुसार प्रस्तुत गर्न सकिन्छ:
यो ट्युबवेलले
केही कम आयाम (Amplitude) का साथ एक
परम्परागत मनसुन-सञ्चालित चक्र प्रदर्शन गर्दछ। यहाँको एक्विफर लचिलो छ, जसले सुक्खा महिनाहरूमा स्थिरता कायम राख्छ र मौसमी पुनर्भरणसँगै
अनुमानयोग्य रूपमा पुरानो अवस्थामा फर्कन्छ। TW-04 ले बलियो
पुनर्भरण, मध्यम
क्षयीकरण र भरपर्दो सुधार सहितको एक सन्तुलित ढाँचा (Balanced pattern) देखाउँछ। त्यसैले यो ट्युबवेल भरपर्दो छ
र यसमा अनुमानयोग्य मौसमी परिवर्तनहरू देखिन्छन्; सेप्टेम्बर–डिसेम्बर
महिनामा केही तनावको पूर्वानुमान गरिए तापनि यो वर्षैभरि उपयोगी र विश्वसनीय
रहन्छ। यस साइटले मौसमी संवेदनशीलताका साथै जल-सामाजिक
उत्थानशीलता (Hydro-social resilience) लाई चित्रण
गर्दछ, जसले अनुकूलनशील जल-उपयोग रणनीतिहरू (Adaptive water-use strategies) को आवश्यकतालाई थप बल पुर्याउँछ।
