\nAbstract: This paper is concerned with identifying the spatial and temporal patterns in the annual maximum and
\nminimum water level in the Pearl River Delta (PRD) region. The Mann\u2013Kendall test and Pettitt test are used
\nto detect trends and abrupt change points, and the Trend Free Pre-Whitening (TFPW) approach then
\neliminates the effect of serial correlation in data series with significant autocorrelation. Approximately fifty
\nyears of the annual hydrological variables from 18 stations in the three major rivers (the West River, the
\nNorth River, and the East River) are examined. The changing trends of the extremes in water level show
\ndifferent features in different parts of the PRD region. Generally speaking, in the upper part of the delta, the
\nwater levels show a decreasing trend while in the middle and lower part there is an increasing trend. This
\nspatial pattern of the extreme water level variation is unlikely to be due to a long-term change in stream flow
\nin the PRD region because the water level changes do not always coincide with the extreme stream flow
\nvariations. Sand excavation initiated in the 1980s and continuing for more than 20 years in almost all
\ntributaries around the PRD region is one of the most serious intensive human activities affecting water levels.
\nThe result of the Pettitt test indicates that most abrupt change points occurred in 1980s\u20131990s, which
\nreveals that sand excavation and channel regulation are likely to have been the most significant factors
\ncontributing to the change over this period. These anthropogenic activities modify the annual extreme water
\nlevel dramatically in a way that affects the morphology of river channels and estuaries of the PRD and also
\nthe redistribution of discharge. However, there are differences in the geographic locations of significant
\ntrends for the water level investigated, which implies that these impacts are not spatially uniform.<\/p>\n
