Water flows in the natural environment

This project delves into water flow, currents, and sediment transport in natural environments. Field experiments are conducted with instrumentation measuring velocity, temperature, and salinity to study the impact on safety, habitat, and pollution. The research includes detailed data collection using various instruments to analyze water temperature, velocity, and depth. The project aims to understand the complex behavior of water flow, conducting both field experiments and computer simulations.

  8. Field Instrumentation:other • 2 weather stations: • Air temperature, relative humidity, velocity, net radiation • GPSs

  9. Pen & paper theory • Water is not created of destroyed, and F=Ma… • Leads to pdes for water motion, sometimes can be solved with standard applied math techniques.

  10. Computer simulations
