LLT MIKE 11 This typically requires that the starting point zero chainage are defined as the upper part and the end the point of the river system are defined in the downstream part of the river system However in many surveys the downstream point e g the river mouth at the sea is the starting point for the river survey and this point is therefore required to be the starting point zero chainage for the river model as well Therefore in these cases it is required to specify the flow direction as Negative as the increasing chainages will then be opposite to the standard notation used internally in MIKE 11 e Maximum dx The maximum selected distance between two neighbouring h points in the computational grid e Branch type The branch type can be selected as one of two Regulat The regular branch is the standard branch of MIKE 11 comprising water level points at both the up and downstream end and an alternating grid of water level and discharge points Link Channel When a branch has been defined as a Link channel type the Edit Link Channel Parameters button is made active Press the button to open the Link Channel Parameters dialog where Link channel parameters can be specified Important notice After specification of the link channel parameters it is required to press the Calculate Q h relations button in order to calculate the link channels Q h table which is used in the computation Afte
