Flow Chart 1: Summary of the proposal

Beginning: Wong Yee Vern

2.1 Introduction

In the twelvemonth of 2001, Government has sort out a solution that would let a terrible inundation to come in into the metropolis without deluging or do harm to the metropolis Centre. An thought was proposed by the Government to implement a undertaking named SMART Project by building a tunnel which serve a double intent in mitigates the inundation issue and easiness of traffic congestion. The procurement method of this undertaking is design and build contract and is carry out by a joint venture between Malaysian Mining Corporation and Gamuda Sdn Bhd. Meanwhile, the concessioner of the undertaking is Syarikat Mengurus Air Banjir & A ; Terowong Sdn Bnd and undergoes a grant period of 40 old ages. The building method of SMART tunnel is utilizing Tunnel Boring Machine ( TBM ) method and it cost around RM 1.9 billion to build. Design of the tunnel is consider every bit alone as it is divided into 2 decks and the length of the tunnel is about 9.7 kilometer with an outer diameter of 13.2m. The building of SMART Tunnel began on 25 November 2003 and officially operates on 14 May 2007.

2.2 Physical Components of Stormwater System

The SMART system is a sequence of storage, fading and regulated flow. The system diverts inundation discharges from the metropolis Centre and later releases them downstream while guaranting the inundation job is non transferred elsewhere ( Ir. Ng Koh Hing, Ir. David N. Welch & A ; Subathra Devi Ramachandram, 2008 ) . No overflow shall happen by guaranting the system optimizes the storage, fading and ordinance within and next to the system. By and large the beltway system consists of consumption and mercantile establishment system.

Besides that, the consumption and mercantile establishment system consist of a dust remotion system complete with drifting roars, rubbish rack and a dust remotion and disposal unit. A river flow recreation system complete with a 4-bay recreation weir construction and an 8-bay offtake construction shall besides be portion of the consumption and mercantile establishment system. Then a set of twin box culverts which gated at both terminal conveys the discharge from storage reservoir to Kerayong. Furthermore, a keeping pool will be situated at the upstream of the tunnel with a storage capacity of 600,000 three-dimensional meters and a storage semen fading pool with a storage capacity of 1,400,000 three-dimensional meters located at the downstream terminal of the tunnel.

2.3 Operation of the SMART System

When there is an event of cloudburst of rain, the information collected will be analysed to foretell the operation manner of SMART Tunnel. For case, when manner II is predicted by the analysis of informations collected so action will be taken consequently. Initially, this means that the defined operating regulations will be operated and the sequence of operation will be displayed for monitoring and supervising intent in Stormwater Control Centre ( SCC ) which involved the operation of assorted Gatess. The manner of operation of SMART tunnel will be subdivided into 4 manners.

2.3.1 Operation Rules of SMART Tunnel

Before

2.3.2 Manners of Operation

The operation of SMART tunnel and expressway is depend on the inundation status at the upstream of Klang River or Ampang River and works on four rule manner. The principle manner of operation system of SMART tunnel can be referred to calculate 1.2.

Manner I

This is the manner when the raining H2O is really small and traffic is allowed in the tunnel therefore no recreation of H2O into the tunnel is required.

Mode II

This manner is activated when the flow rate is between 70-150m3/s which means that when the flow rate of the rainwater recorded at the upstream is between these rate, Mode II will be automatically activated. The route tunnel traffic will stay opened to the route users but the extra inundation H2O will be diverted to the keeping pool and the lower deck of the tunnel will impart the inundation flow to the fading pool with a flow rate of 50m3/s.

Mode III

When there is a heavy rain autumn, this manner will be activated and the flow rate is 150m3/s or more. However, the traffic is motorway is required to be near down in order to let the H2O channel through the both tunnel. Under such fortunes, the tunnel will be near up to 8 hours after the rain Michigans to make some care work.

Mode IV

After the 2 hours of declaration of Mode III, this manner will be activated if the rain H2O storm prolong and the route tunnel will be re-opened to the traffic merely within 4 yearss of closing. Furthermore, the tunnel will be used for channel the inundations after the completion of emptying of traffic.
