| Summary: | Infrastructure development on University of Gadjah Mada raises issues
regarding water resources which is the increasing of runoff discharge. UGM as
an environmentally awareness campus should provide an example of a
sustainable drainage system to reduce floods that occur in urban areas of
Yogyakarta. This relates to the upstream of Kali Belik at the north of UGM that
pass through the campus. UGM campus is inside of Kali Belik watershed thus
affecting the runoff discharge flow to Kali Belik. If the dimension of the channel
can�t accommodate the flow of water passing through Kali Belik, overflow will
happen and some areas of the city will be flooded.
This research was conducted by collecting both primary and secondary data.
Primary data were obtained from direct observations and surveys in the UGM
campus environment. Secondary data were collected from the Directorate of
Planning and Development UGM (DPP UGM) and the Directorate of Asset
Maintenance and Management UGM (DPPA UGM). The data was analyzed and
modeled using rational methods and flow routing to obtain runoff discharge, flood
hydrograph for a retention pond with return period of 2, 5, 10 years and the
condition of existing retention pond .
Implementation of water conservation techniques in UGM is the existing
infiltration wells in Region-1 (Faculty of Agriculture, Faculty of Forestry, Faculty
of Agricultural Technology), 2 (Faculty of Social Political Science), 3 (Faculty of
Psychology and UGM residence area), and 5 (Faculty of Animal Science) each
has 7, 15, 12, and 3 wells . The number of wells in each catchment area can
absorb water discharge for 0,02 m3/second |
