Sediments from Lunkaransar dry lake in northwestern India reveal regional water table and lake level fluctuations over decades to centuries during the Holocene that are attributed to changes in the southwestern Indian monsoon rains. The lake levels were very shallow and fluctuated often in the early Holocene and then rose abruptly around 6300 carbon-14 years before the present (14C yr B.P.). The lake completely desiccated around 4800 (14)C yr B.P. The end of this 1500-year wet period coincided with a period of intense dune destabilization. The major Harrapan-Indus civilization began and flourished in this region 1000 years after desiccation of the lake during arid climate and was not synchronous with the lacustral phase.
印度西北部伦卡兰萨尔干湖的沉积物揭示了全新世期间数十年至数百年的区域地下水位和湖面波动情况，这些波动归因于印度西南季风降雨的变化。全新世早期湖面很浅且波动频繁，然后在距今约6300碳-14年（公元前14C年）时突然上升。该湖在距今约4800（14C）年时完全干涸。这一持续1500年的湿润期结束时，恰逢沙丘强烈失稳的时期。在该湖干涸后的干旱气候期间，主要的哈拉帕-印度河文明在这一地区兴起并繁荣，且与湖泊期不同步。
