Precipitation monitoring is an essential activity for water management, as it provides measures of the main driver of hydrological processes. Precipitation monitoring is conventionally carried out with sensors that remain in the same location for extended time periods (static sensors). However, it is known that precipitation is not homogeneous as events develop. To increase the efficiency of the conventional monitoring networks, we propose the use of sensors that can travel to different locations as events develop (dynamic sensors), as well as scaling the number of sensors with the help of volunteers (citizens). In this thesis is developed a method for merging heterogeneous precipitation observations in non-stationary precipitation fields, exploring the interactions between different definitions of optimality for the design of static sensor networks, and developing of algorithms for the optimal scheduling of dynamic sensors. Results indicate that dynamic sensors increase the coverage of the precipitation sensor networks.
