Abstract
Water resources allocation has been planned, depending on a regional activity plan whose object was to attain only the efficiency of a regional economy. The need of environmental impact assessement on this plan is examined.
A model is given for a water resources allocation planning which extends over a region consisted of a number of districts, whereas the desired value of water quality in a coastal sea is pre-fixed. In order that the desired value may be considered as a constraint in the model, a state of current in a coastal sea is described by a simulation technique, based on the Navie-Stokes equation in the field of hydraulics. And using the state of current it is shown that a Load Impact Matrix is made by a diffusion equation. The flow chart for making the load impact matrix is depicted in Figure.
A water resources allocation model is first set up, and it is shown that the solution method is a decision making process between the plan of each district and a regional plan which satisfys the desired value of water quality in the coastal sea. It is shown that the model can be applied efficiently in water resources allocation problems in a numerical example.
