A case with incomplete information passes through intermediate decisions and processes along its life cycle before it becomes a mature one to be retained in the case base. Environmental cases in case-based reasoning (CBR) go into successive steps, each step depends on its past actions. A spatiotemporal environmental case may not be completely similar to another case in the case base, but rather a subset of it can have a similar session of a stored case. In this paper, we shall consider water resources management scenarios in newly reclaimed areas as incomplete spatiotemporal cases, with organizing the case base in a suitable way to capture cases or sub-cases that are similar to our new one or a subset of it to induce constraints of water resources exploitation plans, then relaxing or more restricting those constraints later as new information are available until the input case becomes a new complete one to be stored in the case base.
