difference between diversion and transimission yongxuan gao xuangao <a href="mailto:xuan.gao@tufts.edu">xuan.gao@tufts.edu</a>Could anyone tell me what the difference between a diverison and a transimission line is? When should I use which?

Thanks.

A transmission link transmits water from a supply source (reservoir, river node, groundwater node or "other supply" node) to a single demand site. A transmission link can have a maximum capacity, either as a percentage of the demand it is supplying (e.g., 50% of demand) or as an absolute flow rate (e.g., 0.5 cubic meters per second).

In contrast, a diversion functions very much like a river--there can be multiple inflows and outflows, reservoirs, groundwater interactions and flow requirements. Typically, a diversion begins by drawing water from a river or another diversion. WEAP will only pull as much water into the diversion as is required by demands or flow requirements on the diversion. A diversion can have a maximum capacity as an absolute flow rate (e.g., 0.5 cubic meters per second). However, a diversion can not transmit water directly to a demand site--you will need a transmission link to move the water from the diversion to a demand site.

Use a transmission link to move water from a supply to one demand. Use a diversion if you want to model a canal or pipeline that supplies more than one demand site, or that has flow requirements or reservoirs to control the flow.

I think we should use the diversion if we want to control the flow from the river into the reservoir, by flow requirements on the diversion, when we want to storage a defined quantity of water in the reservoir .

Because we can't control the flow from the river into the reservoir by transmission link.

Respected Sir,

As you mentioned that WEAP will only pull as much water into the diversion as is required by demands or flow requirements on the diversion. So, can we restrict WEAP to divert such amount of water which we insert in the diversion rather than pulling water based on demand.I mean can we restrict it to pull specified amount of water irrespective of the demand? If Yes then How?

Dear Muhammad,

There are ways to specify how much water the diversion will take, but I would ask a few questions first:

You use the word "restrict" so I believe you would like the flow to sometimes be less than the demand. What is causing this restriction? If it is due to insufficient water supply, then there are better ways to model this. If it is due to physical constraints, then there are better ways to model this. Can you tell me more about your system so we can determine the best way to simulate its dynamics?
