Abstract Regional rainwater resources potential is crucial to rainwater utilization planning, water resources exploitation and ecological environment improvement in semi-arid area. The definitions of rainwater and rainwater resources potential were discussed. The methods to evaluate the influences of topographical features, rainfall features and utilization ways on regional rainwater resources potential were put forward. Finally, the model and procedures to calculate regional rainwater resources potential were developed and used to assess the rainwater utilization planning.
