本研究は、インドネシアの丘陵住宅地を対象にEPA SWMM 5.2を用いてLID施設（雨水貯留を含む）による雨水排水対策を評価。3シナリオ比較の結果、LID＋貯留の併用で総流出量が42.58%削減され、ピーク流量は72.73%減衰した。サブキャッチメント4–6のLIDは75.33%削減と最も高かった。
English
This study evaluates nature-based solutions (LID facilities) in a residential drainage system using EPA SWMM 5.2 for a hilly Indonesian residence. Three scenarios were compared; combined LID plus storage cut total runoff by 42.6% and attenuated peak discharge by 72.7%. Bioretention, permeable pavement, and rain gardens each reduced runoff significantly, with LID in subcatchments 4–6 achieving up to 75.3% reduction.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本でも都市型水害対策やグリーンインフラ活用が進む中、LIDのKPI評価手法は自治体や不動産開発の適応策検討に参考になる。
In the global GX context
As climate adaptation becomes part of disclosure (TCFD/ISSB climate resilience), this provides quantifiable KPIs for NBS performance in drainage, relevant to urban climate adaptation and infrastructure planning.

📄 Abstract（原文）
Grand Panorama Residence lies on the foothills of Mount Gede Pangrango and has hilly, undulating terrain that accelerates runoff toward lower roads and drainage channels. This study evaluates Nature-Based Solutions through Low Impact Development facilities modeled in EPA SWMM 5.2 to improve neighborhood drainage resilience. Model inputs included annual maximum daily rainfall from Cisalada Station for 2006–2025, drainage dimensions, elevations, and catchment characteristics. The model covered 2.13 ha and comprised 14 subcatchments, 40 junctions, 53 conduits, and 4 outfalls. Three scenarios were assessed: drainage without LID, drainage with combined LID, and drainage with LID plus storage. Performance indicators included runoff volume reduction, peak runoff reduction, flow velocity change, drainage load reduction, and storage attenuation. Total runoff volume decreased from 414.02 m³ to 237.73 m³ after LID implementation, equal to a 42.58% reduction. The combined LID system in subcatchments 4–6 achieved the highest runoff reduction at 75.33%. Bioretention, permeable pavement, and rain gardens reduced runoff by 41.48%, 25.46%, and 38.26%, respectively. Storage reduced peak discharge from 0.011 to 0.003 m³/s, corresponding to 72.73% attenuation. Combined LID and storage provided the most effective overall strategy.
