Project Report
:
The project consists of a single volume as stated below:
Final Report
Background
:
The River
Inventory and Monitoring Program (RIMP) is a depository of riverine
information and a clearing house whereby public can seek information and
data on Sarawak's rivers. it is a federal and state collaboration
project funded by the Ministry of Natural Resources and Environment (NRE),
commissioned by Sarawak Rivers Board (SRB).
Study Area
:
This study covers the
area of Sg. Sarawak Basin, from estuary (Muara Tebas) to upper
catchments. However, river modelling work only involves area from
Kuching Barrage to upstream region due to constraints of data, time and
cost. The model however can be upgraded to covers the downstream area
(From Barrage to Muara Tebas) in future when the required data is
available.

Scope of Work :
The scope of work for this study is to
submit a proposal that formulate conceptual framework which shall
include physical structures, manpower requirement and financial
implication such as capital outlays, recurrent operating cost and
finalizing the detail requirements and total cost estimate of each
component of the project:
-
To formulate conceptual design and
components need for the implementation/build-up of River Information
Center (RIC) at the Sarawak Rivers Board, HQ in Kuching.
-
To be utilized as one of the input
component to formulate plans for the implementation River Monitoring
Program (RMP).
-
To formulate plan for the set-up of
river profiling and inventory
program (RPIP) for Sarawak River in a short-term period.
- To propose
computer networking required at the Sarawak Rivers Board, HQ in
Kuching.
River Profiling and
Inventory Program (RPIP) :
A
database and RIMP website for this River profiling and Inventory Program
have been suggested. The database is suggested according to the project
objectives and it is expandable to include a wider scope of interest in
future. On the other hand, the suggested RIMP website is to provide an
interface so that information stored in the database can be provided to
interested parties. The website would consisted of 10 components (Home,
General Information, River Profiling, Flood, Navigation, GIS, Newsroom,
Publications, Webcams and Contact) which provide information related to
Sg. Sarawak and a number of internal/external links in which extra
useful data and information can be obtained.

River Modelling :
A
Sungai Sarawak basin-wide model is developed using the InfoWorks
software. Flood mapping of extreme events, like the
50-year
return period flood in February 2003, and
100-year return period
floods in January 2004 and January 2009 floods have been computed to
give insights to the river processes in Sungai Sarawak. The modeling
results would be useful for decision support purposes in river basin
management.

Networking System
:
Based on the existing network facilities
and system requirement, the most suitable Server and Network devices
have been proposed to ensure sufficient data storage capacity, bandwidth
for proper transmission of data and web streaming (e.g. from telemetry
stations to server and from server to cloud), etc.

Conceptual Framework and
Project Components :
The
overall conceptual planning for this River Inventory and Monitoring
Programme is shown below. Further detail on the function of each component,
Infrastructure & manpower requirement, Cost Estimation, suggested
CEPA, etc are provided in the final report.
