A small-scale experiment is conducted to estimate domestic water-use rate in the city of Rabat-Salé. Water consumption 171 households has been closely monitored over a 24-month period. During this survey both net monthly volume tap water effectively used each household and exact number people who have lived same are observed. This resulted series reliable realizations daily per-capita (denoted ...

Water is an essential yet constrained commodity for human communities and ecological systems depend on it. With population growth and economic development, water resource is increasingly declining. Over the past two decades, because of changes in population and climate, and relative welfare increase, the per capita consumption of water has increased. Thus, optimal use of available water resourc...

A system dynamics method to assess carrying capacity of a defined natural environment is presented. The proposed method seeks to relate per capita resource usage to ranges of population and per capita consumption beyond which the system is not viable relative to population dependent resource constraints. It provides a platform to investigate system behavior through system dynamics simulations w...
