Continuous Hydrologic Modeling of a Parking Lot and Related Best Management Practices with PCSWMM

چکیده
Permeable pavements are a green infrastructure stormwater management practice that can serve as functional component of the site design. However, previous field studies suggest high uncertainty in parameters used for performing hydrologic calculations permeable pavements. The Environmental Protection Agency (EPA) Storm Water Management Model (SWMM) within PCSWMM software package was to simulate dynamics parking lot is 25% covered with interlocking concrete pavers Auburn, AL. model calibrated observations water level at two points where pavement system outflows bioretention basin and rainfall data from nearby weather station. use Curve Number (CN) method SWMM resulted good prediction outflow by model, R2 Nash-Sutcliffe efficiency both greater than 0.8, except issues precipitation coverage occurred. This demonstrates be modeled land cover type rather detention storage. value runoff CN 60, much lower what recommended many design guidelines underlying soil research site, which group B. Based on evaluation alternative scenarios, reduced 11-38% across contrasting rain events.

Hydrologic Modeling of a Canal-Irrigated Agricultural Watershed with Irrigation Best Management Practices: Case Study
Simulating irrigation systems by accounting for various water loss rates is necessary while modeling the hydrology of cultivated canal-irrigated watersheds. The existing approaches to modeling canal irrigation use situation-specific optimization procedures. In addition, they are focused on a water management perspective rather than a hydrologic perspective. In this study, an approach is develop...

abstract while task-based instruction is considered as the most effective way to learn a language in the related literature, it is oversimplified on various grounds. different variables may affect how students are engaged with not only the language but also with the task itself. the present study was conducted to investigate language and task related engagement on the basis of the task typolog...
