What is your approach to conducting detailed hydrologic and hydraulic modeling for stormwater infrastructure projects?

SENIOR LEVEL
What is your approach to conducting detailed hydrologic and hydraulic modeling for stormwater infrastructure projects?
Sample answer to the question:
When it comes to conducting detailed hydrologic and hydraulic modeling for stormwater infrastructure projects, my approach is to start by thoroughly analyzing the project requirements and objectives. I then gather all the necessary data, such as topographic information, rainfall data, and soil characteristics. Once I have all the data, I use software like HEC-HMS and HEC-RAS to simulate the flow of water and analyze the hydraulic behavior of the system. I pay close attention to factors such as runoff coefficients, time of concentration, and channel capacity. Throughout the modeling process, I ensure that all the calculations and assumptions are accurate and properly documented. Once the modeling is complete, I interpret the results and use them to inform the design of stormwater management systems that effectively mitigate flooding and improve water quality. I also collaborate with other team members, such as civil engineers and landscape architects, to integrate the stormwater management systems into the overall project design.
