| dc.description.abstract | Pondok Lapan Lake is an artificial lake located in Langkat. In the map, this lake is
located on the axis of coordinates precisely 3°30′44.73" N - 3°30'26,29" N dan
98°. 17′ . 65" E - 98°17'29.60"E. The purpose of this study was to determine the
morphometric aspects Pondok Lapan Lake and determine the capacity of water
utilized by society. The research was conducted from January to March 2015.
Data collection is performed in this research is data depth, water flow, and around
the lake are processed using ArcView. From the results, the lake morphometric
aspects of wide Pondok Lapan Lake is around 63472.78 m², the maximum length
of 548.28 m, 220.23 m maximum width, circumference 2200.83 m, maximum
depth of 4:15 m, with a sloping bottom waters and shape of the lake bottom
surface is irregular. And the capacity of the Pondok Lapan Lake which can be
used by the public is 104679.59 m³ of water volume, water flow around
12963,456 m³/day-14111,712 m³/day, Recidance time of water about 8 days, the
brightness of the water approximately 0.965 m – 1.056 m with a depth of
approximately 2.612, compensation m-2.858 m | en_US |
