The
coordination was attended by Daw Ei Ei Su Mon (Staff Officer, DMH), U Min Oo
(Deputy Director, DHPI), U Myo Tint Htun (Assistan Director, DHPI), U Oo Kyaw
Aye (Staff Officer, DHPI), Dr. Aung Than Oo (Assistant Director, Irrigation
& Water Utilization Management Department – formerly Irrigation
Department), U Aung Kyaw Hmuu (Director, DWIR), U Kyaw Naing Oo (Assitant
Director, DWIR), and U Htay Aung (Deputy Director, Bridge Department – Ministry
of Construction). The aim of the meeting was to finalize the location of the
observation sites, potential date of succeeding installation, design of
stilling basins for the floating-type water level gauges.
The
group was able to agree to the selected sites for the observation systems. The
locations of the weather observations were easily finalized. Major discussion
points were the location of the water-level gauging stations due to the
construction and design of the stilling basins necessary for the floating type
gauging stations. The Zaung Tu dam water-level gauge to be under DHPI was
identified to be situated just downstream of the confluence of the dam outflow
and small tributaries of Bago River. The Tawa water-level gauge to be under
Irrigation Department was previously identified in a site visit to the area and
was confirmed in this meeting. The Kalawe Bridge installation to be under DWIR
was also confirmed in conjunction with the proper request for permission from
the Bridge Department under Ministry of Construction. U Htay Aung served as the
representative from the Bridge Department and confirmed an initial
understanding with the group in requesting proper permission from the Ministry
of Construction for the installation of observation system on the bridge.

Coordination Meeting at YTU with
ID, DWIR, DHPI, DMH, and Bridge Department - MoC
|
The group discussed the potential succeeding installations
and limitations of the departments in supporting the installations. The main
problem for the succeeding installations was access to the sites as the sites
are mostly accessible by boat only during the rainy season. Other concerns
include budget request limitations of the agencies. Due to the constraints, the
group agreed to potentially proceed with the succeeding installations by the
succeeding dry season around January. The time is also needed to prepare proper
request permissions, some budget requests of departments, and design of some
related structures primarily for the floating-type water level gauges.
Regarding the design of the stilling basins, a lot
of concerns from the group were primarily focused on the sedimentation problem
if the structure will be built near the riverbank. In addition, foundation
design of the structure is also a big concern with regards to the softness of
the material on the riverbank and the height of the structure due to the large
water level variation in the site location. Dr. Aung Than Oo of ID shared his
experiences with the group on the design of the stilling basins. The group
concluded on a specific understanding regarding the design and the need for
flexibility of the design based on the potential problems we might in encounter
on site after installation. The group concluded to enhance further
collaboration in designing the stilling well to ensure the long-term
effectiveness of the observation system to be installed.
