7 12d Solution Pty Ltd 3.0 Starting with a Baic Drainage Network Thee coure note aume that you have completed the Stormwater Deign Coure and that you have experience creating 12d model drainage network with catchment area. Thi coure will begin with a completed drainage deign found in the directory \12djob\coure\7.00\drainage\local road complete 4.0 Excavation Quantitie Sample template are included in the coure ection of 12djob (\12djob\coure\7.00\drainage\pipe template.tpl). The template from thi template library may be added to your project uing Deign=>Template=>Utilitie=>Input. Thi routine ue 12d template to calculate the excavation volume for all of the drainage tring in a model. An option to create ection for a tin on top of the pipe i alo available o that the drainage long ection can include hatching between the obvert of the pipe and the deign tin under road. Template with name et to the pipe diameter (time 1000) are ued for the calculation, thu trench hape can be cutomied and over excavation for bedding material can be included. Net area calculation to exclude pipe area are not upported. Key point 1. One template for each pipe ize (mm) 2. If obvert template are ued, add the prefix obvert to the pipe ize 3. Carefully conider the tin elected. A template mut exit for each pipe ize in the model (pipe ize x 1000). For example a 0.3m pipe will require a template to exit named 300. A 0.5ft pipe would require a template named 500. Sample template are included in the coure ection of 12djob (\12djob\coure\7.00\drainage). Thee may be copied to your *.project directory and then added to your project uing Deign=>Template=>Utilitie=>Add=>All all to project. The template are run along the tring and the total volume are reported. Volume for each tring are given in the report file. An example follow.

15 12d Solution Pty Ltd 6.0 Exporting to Drainage Deign Software Package 12d contain mot of the data required for your drainage deign package. However, each package ha pecific deign variable that 12d doe not have acce too. The deign proce i intended to export your data from 12d to the deign package, deign the drainage ytem and then read the reult back into 12d for your long ection. If pit/pipe are to be added/deleted from your network during the deign proce you are afet to add/delete the pit/pipe to 12d and to your deign package eparately. Not recommended and a a poor alternative, you have the option of reading the reult back into 12d, adding/deleting the pit/pipe and then exporting the data to a new drainage project in your drainage deign oftware. A 12d doe not have acce to all of the data in the deign package thi method i not recommended! Some of the drainage deign program offer a third option that allow you to import data on top of an exiting project thereby merging and over writing the exiting data. Be ure to contact the drainage oftware upplier to obtain exact detail of how the merging proce i performed.

22 4D Solution Pty Ltd When 12d export the drainage model to a preadheet it include a column for the unique tring identifier and a unique manhole identifier (unique to the drainage model not the 12d project). The name of the tring and manhole may be changed via the preadheet if thee column are preent at import time. If the manhole id column i not preent, 12d will earch the drainage model for a matching manhole name. When the manhole i a junction between drainage line, only the trunk line will be the data updated Creating a New Model It i poible to create a new tring or an entire drainage network uing thi format. However, manhole cannot be added to an exiting tring. The entire drainage tring mut be created at once. Two format are available, the from-to manhole format and the 12d drainage preadheet format. At preent the network editor mut elect a drainage tring to become active. Therefore, if you are not adding tring to a network, you will have to great a drainage network with one dummy manhole. Select thi one dummy manhole to activate the editor. After importing the data and the new drainage line are created the dummy manhole may be deleted. 12d drainage preadheet Format The top left cell in the clipboard data mut be the text 12d to pecify thi format. The minimum amount of data required to create a new tring i the tring name, manhole name, x and y coordinate. You can add a much additional data a you have available. Thi would include pipe diameter invert etc. The manhole mut be lited from uptream to downtream order. If the tring i to join a trunk line, the junction manhole mut be included for both the tributary and the trunk line. An example file exit called new_network.txt i upplied in the library. Open thi file in a preadheet or a text editor and copy it to the clipboard. Set the I/O Action to Import and elect Run. The new drainage line will exit in the model currently being edited. From-to Manhole Format The top left cell in the clipboard data mut be the text from to to pecify thi format. The minimum amount of data required to create a new tring i the uptream pit name "*pit name), the downtream pit name (*d pit name) and the x(x location) and y(y location) coordinate of the uptream pit. If the tring i to join a trunk line, the junction manhole mut be included for both the tributary and the trunk line. An optional column for the manhole cover elev (cover elev) may be pecified. Once the network ha been created additional pipe and manhole data may be added uing the 12d drainage preadheet format decribed above.

The later require unique name for the bypa flow tring. Many of the deign program 12d export to allow for bypa flow. Bypa flow involve the calculation of inlet capacity which i often baed on the road grade uptream of the manhole. Key Point 1. Set the manhole type to name that ignify the inlet type in the program you are exporting to (Type on the Pit->Main tab). 2. Check that your grate level i correct (Setout z + Setout to grate offet) 3. Mark the manhole a a On grade or SAG inlet (Inlet data on the Pit->Main tab). On grade inlet capture the water a it pae the inlet while SAG inlet trap the water flowing in from all direction. 4. Draw an bypa flow tring in the direction of flow o that it pae within 1 manhole diameter of the inlet. When bypa flow tring join they mut join within 1 manhole diameter of a manhole. If flooded with calculation are to be done later, the bypa flow tring mut have a unique name and the tring hould located in the flow channel. Enter the model name in the Bypa flow model field on the Global->Utility Model tab. 5. Enure a etout tring i linked to the inlet o that the road grade may be calculated in it direction.

Select the deired inlet chart BEFORE importing the interchange file. 12d manhole type with an S in the name are treated by 12d and PCdrain a a SAG inlet pit. 12d will trip off all character after the S before adding the ponding depth. If a catchment tring in et #1 i available for the SAG pit then the ponding depth will be calculated.the12d manhole type will remain unchanged. A typical example would be a manhole type 1TC with the ag tick box on would become 1TC0.100 if a ponding depth of 0.1 wa calculated. Bypa Flow When a catchment tring i pecified for the manhole, the maximum depth before bypa flow commence i calculated. The lowet point on the catchment tring i determined by draping it onto the drainage tring tin. The maximum depth before bypa i calculated manhole etout level le the etout to grate offet le the lowet point on the catchment tring. PCdrain differentiate between manhole (no urface inflow) and gully pit via the 12d manhole type. The bypa flow tring can only be drawn within 1 manhole diameter of the gully pit.

An example entry may be found in the ection The drainage.4d file on page On grade pit Crofall data mut never decreae moving down the table while the gutter grade data mut increae for a contant crofall. When the table are being read, the next et of capacity factor will not be ued until the crofall and grade are equal to or exceed the value in the table. The factor are not interpolated! Drain and ILSAX The cap1, cap2, cap3 and cap4 value are ued to decribe the inlet capacity of the pit a decribed in their uer manual. RAT-HGL If cap2, cap3 and cap4 are all equal to zero then a fixed inlet capacity equal to cap1 will be exported to RAT-HGL. If the um of thee three value i greater than zero then a pit type will be created in the format of pit_type-crofall-roadgrade. For example SA2-3-2 for a SA2 pit with a road crofall of 3% and a road grade of 2%. A rating curve with thi name will have to exit inide RAT-HGL. 12d ha no way of tranferring the rating curve itelf into RAT-HGL.

65 12d Solution Pty Ltd 16.0 Flooded Width Analyi and HEC RAS The Calculate Flooded width procedure create cro ection along the bypa flow path and then calculate the flooded width at each ection uing Manning normal depth calculation. A HEC-RAS project (ame name a the bypa flow tring) i alo created for each line. The flooded width i indicated on each ection a a blue line if it i le than a uer defined width and a red line if the flooded width exceed the limit. Detail of the calculation uch a the velocity, depth, wetted perimeter and lope can be exported to a preadheet for further analye (velocity time depth calculation for example). The dicharge import from the urban tormwater deign package are hown in the following table. Deign Program PCdrain Drain ILSAX RAT HGL Dicharge Event Minor ARI Maximum flow event analyed Maximum flow event analyed Firt return period analyed The uer define the length of thee ection and the interval at which they are to be paced. 12d calculate the normal flow depth interpolating the pit approach and bypa flow from the hydrology model (ILSAX, Drain, PC Drain or RAT HGL). The cro ection are taken perpendicular to the flow line and the lope i for the normal depth calculation i determined uing the ditance along the flow line and the change in elevation between the two lowet point in the primary flow channel. The flow line need not interect the low point on the ection but the flow line doe mark the primary flow channel. If the depth of the flow exceed the bank of the primary channel, then all adjacent flow channel will be conidered a active flow area Limitation where overland flow line join Where overland flow line converge at a manhole, 12d doe not know the flow plit between the 2 approaching path. Therefore, 12d ue the total flow from all line a the flow at the manhole for each line. Thi may overetimate the flooded width along the flow line at thee point Limitation at SAG pit The flow width are not hown adjacent the ag inlet. The depth of flow due to ponding and the approach flow coming from everal direction may overetimated flooded width in thee area. Therefore not flood depth are calculated approaching SAG inlet.
