8 Hydraulic and Water Quality Modeling Transient Flow Analysis The governing equations are solved by the fourth-order-accurate, space- compact implicit finite difference scheme (Verwey, Yu, 1993). The scheme was developed by adding two Preissmann type operators over two successive time levels and by subtracting all third-order derivative terms of the truncation error. This was achieved by converting all third order derivative terms to a form 3t/xt2, which can be defined in finite difference form on a part of the grid limited to two successive points in space and three points in time (Ingeduld, 1994).

41 MIKE NET Demand Processing Demand allocation Incorporation of geo-referenced information to develop node demand from the customer information systems
42
42 MIKE NET Demand Processing Demand distribution For large network systems, assigning demand data can be very tedious job. Since many times the total demand is known for a particular network pressure zone or for the entire network system, MIKE NET provides the capability to distribute this total demand among the applicable junction nodes MIKE NET computes the water demands for each node in the network system based upon the total network demand using two methods: the Method of Pipe Lengths and the Method of Two Coefficients. These methods are used to mimic the amount of actual demand along a pipe, based upon the pipe length or pre-defined demand coefficients
43
43 MIKE NET Demand Processing Demand distribution Method of pipe length The Method of Pipe Lengths computes the total water demand assigned to the current pipe as: q pi = (Q - o i ) l i k 1i / (k 1i l i ) Method of two coefficients The Method of Two Coefficients computes the total water demand assigned to the current pipe as: q pi = (Q - o i ) k 1i k 2i / ( k 1i k 2i )
