(50 pts) The StreamStats report for a tributary watershed of the Catalpa Creek is presented below. A development project would convert the watershed to an entirely urban system. The forest land of the watershed would be converted into a Highly Developed area. Using a precipitation design of 5.92in and a duration of 24 hours, complete an entire hydrological analysis to determine:

2. The additional runoff depth and volume that would be observed in the watershed due to the urban development

3. The size of a squared detention pond that could be implemented to store all the runoff excess if the maximum depth of the system is 10 ft

4. The differences in peak flow between pre and post development senarios

1. (50 pts) The StreamStats report for a tributary watershed of the Catalpa Creek is presented below. A development project would convert the watershed to an entirely urban system. The forest land of the watershed would be converted into a Highly Developed area. Using a precipitation design of 5.92-in and a duration of 24 hours, complete an entire hydrological analysis to determine: 2. The additional runoff depth and volume that would be observed in the watershed due to the urban development 3. The size of a squared detention pond that could be implemented to store all the runoff excess it the maximum depth of the system is 10 ft 4. The differences in peak flow between pre and post development scenarios To report your findings, you must show step by step any individual calculation. You must include the curve Number table you use to calculate the corresponding values. Be sure you identify each variable used and keep units all the time, including on preliminary steps into the equations. If you missed to include units, you will be penalized individually on each problem. Use proper number of decimal units (2 or 3) depending on the dataset in analysis. 2. (50 pts) A 2-hr duration stormflow event was observed in a specific location along the Cooneewah Creek in May 2019 and is presented in the table below. A rain gage for the area registered a total precipitation event of 1.5-in. Assuming the total amount of interception and infiltration remains constant during the event in around 50% of the precipitation depth. A huge storm event of 10.5-in was observed in the same area in June 2019 (sequence in table below). The device used to determine flow discharge went out of service and the dataset of the behavior of the stormflow event is needed to evaluate flooding impacts in the area.
