Over last 42 years, most of the rainfall during the summer monsoon season in theKathmandu Valley has ranged in intensity
between 0.13 and 0.37mmh−1, based on the
24h accumulation measurement. We infer
that this range of intensity of rainfall can
pose problems leading to the development
of flood conditions in the Kathmandu Valley.
There are numerous occurrences of low
intensity rainfall (0.01–0.25mmh−1), whereas
higher intensity rainfall (4.25–4.50mmh−1)
occurs less frequently. As the aim of this
study is to examine the distribution of the
rainfall intensity over Kathmandu during
the summer monsoon season, we believe
that the aforementioned sets of data have
revealed the information we sought to find.
