| ABSTRACT: | Formulation of a mathematical framework which integrates dynamic decisions on groundwater level observations with dynamic decisions on groundwater pumping rates along a given planning horizon. The problem is presented viewing the groundwater as a stochastic system. At the beginning of each time period of the planning horizon, two consecutive decisions are made: a) the precision of the information to be acquired from the network and, hence the configuration of the observations to be made; b) the quantity of water to be pumped during the time period. The total objective function is the difference between the expected net benefit from managing the aquifer (pumped water and the resulting head) and the cost of the observations in terms of observation precisions. An optimal precision level is one for which the marginal increase in the management objective function equals the marginal increase in the precision cost. The optimal decisions with regard to precision and pumpage at the beginning of each time period are motivated by the desire to maximize the value of the total net benefit function for the remaining periods. The values of the optimal decisions and the value of the objective function are expressed in termof the prior distribution which is dependent on the decisions in the previous period. This feature makes the problem suitable to be solved by stochastic dynamic programming. Some examples demonstrating the procedures and techniques involved in combined network and groundwater management are presented. |
