以下是一些資料整理,讓大家知道烟花颱風對
德基水庫集水區雨量的影響。
首先,要討論集水區雨量就要先認識集水區
的CWB雨量測站。以下這張圖可以讓大家知道
集水區CWB雨量測站的位置:

-----------------------------------------------------
德基水庫集水區邊界有不少測站,這些測站都屬於
分水嶺測站,所以下在這些測站週圍區域的雨水有
機會流到德基水庫所屬的大甲溪流流域,但也有可能
流到其到河川的流域。舉例來說,如果雨水下在集水區
最上方的桃山測站週圍區域,那麼水可能流到大甲溪流流域
,順利流到德基水庫;也可能迷路跑去大漢溪流域,被
石門水庫搶走。

當然,集水區內部也有測站,既然是在集水區內部,下在
這些內部測站的雨水只會流到大甲溪流流域,順利流到德基水庫
,不會被其它河川搶走。因此這些測站的雨量資料很重要。
主要的內部測站有:
01.武陵(武陵農場):沒有出現在上面的地圖,但是的確位於
集水區內部。
02.松茂:沒有出現在上面的地圖,但是的確位於集水區內部。
03.梨山。梨山測站附近有新佳陽測站、梨山國中測站、梨山
圓環測站,我選梨山測站作為這四個測站的代表。
04.畢祿溪站(南投):沒有出現在上面的地圖,但是的確位於
集水區內部。
05.雪山東峰。
06.德基。

(這個網頁有所有CWB測站的分布圖)
----------------------------------------------------------
大概認識完集水區測站,接著討論雨量。
因為烟花是從7月21號開始帶來降雨,所以我只討論7月21號
0時起至現在(7月23號16時)的累積雨量!
以下是各測站的累積雨量排序:
審馬陣(分水嶺測站):224mm
南湖圈谷(分水嶺測站):207mm
桃山(分水嶺測站):190mm
多加屯(分水嶺測站):189mm
思源(分水嶺測站):183mm
雪山東峰(內部測站):91mm
武陵(內部測站):81mm
雪山圈谷(分水嶺測站):73mm
畢祿溪站(內部測站):36mm
松茂(內部測站):33mm
大禹嶺(分水嶺測站):26mm
梨山(內部測站):24mm
合歡山頂(分水嶺測站):14mm
德基(內部測站):12mm
集水區內部的測站表現普遍不佳,梨山測站居然只有24mm。
但是居然有5個分水嶺測站超過180mm,審馬陣測站224mm表現驚人!
CWB的定量降水預報認為今晚到明晨德基集水區會下大雨,希望是真的!
