This paper studies groundwater management in the presence of rainwater harvesting (RWH). We propose a two-state model that takes into account the standard dynamics of the aquifer and the dynamics of the storage capacity and we assume that the collection of rainwater reduces the natural recharge....

This paper is concerned with groundwater management issues in the presence of rainwater harvesting (RWH). Namely, we propose a two-state model in order to take into account the standard dynamics of the aquifer and the dynamics of the storage capacity since the collected rainwater reduces the...
