A rainfall simulator was used to apply a consistent rate of uniform rainfall to packed soil boxes in a study of the fate and transport of urea, a nonpoint source environmental contaminant. Under uniform soil and rainfall conditions, antecedent soil moisture content exerted strong control over urea loss in surface runoff.

FAQs
Feedback allows the calculated behavior of one component to influence other components and, in turn, affect later system states. This creates an iterative representation of interactions rather than treating each subsystem as independent. Including feedback helps engineers examine how control actions and component responses propagate over time, revealing system behavior that isolated subsystem analysis may not show.
Subsystem models represent the behavior of individual parts, while governing equations describe the relationships used to calculate system responses. Operating conditions define the circumstances under which those relationships are evaluated, and control logic determines how the system responds to changing conditions. Combining these elements connects component behavior to overall performance and integration decisions.
System-level Simulation evaluates a proposed configuration computationally before engineers build or modify a physical prototype. It can therefore support earlier examination of architecture choices, operating conditions, and interactions among components. Physical prototypes remain distinct because they represent hardware directly, whereas the computational approach provides a virtual way to test behavior and compare alternatives during development.
Normal conditions show whether the intended architecture performs as expected during routine operation, while demanding conditions expose responses that may not appear in ordinary use. Comparing both cases helps identify bottlenecks, trade-offs, and potential failures before hardware or software decisions become difficult to change. The resulting evidence supports safer and more reliable system development.
A typical workflow begins by representing the relevant subsystems, then connecting them through governing equations and defined interactions. Engineers add operating conditions and control logic so the model can calculate how inputs propagate through the system over time. They can then examine predicted behavior, compare design choices, and use the results to guide architecture and integration decisions.
The approach is especially useful while engineers are developing an architecture, optimizing performance, or deciding how hardware, software, and subsystems should be integrated. It provides a way to evaluate alternatives before building or modifying physical prototypes. This early insight can expose problems sooner, reduce development costs, and focus later physical testing on more informed designs.
Simulation results can indicate how inputs move through the complete system, how components interact, and how control logic affects behavior over time. Engineers can use those results to locate bottlenecks, examine trade-offs, and identify potential failures under selected conditions. These findings support performance prediction, design optimization, virtual testing, and decisions intended to improve safety and reliability.
