A Really Complex Stormwater Model: Salters Creek 2D SWMM

/in , , /by

Engineers from the City of Hampton and GKY & Associates, Inc. recently completed a study of the 2,500-acre Salters Creek Watershed, which discharges to the Hampton Roads Harbor. The area has a relatively flat, low-lying topography with drainage infrastructure that is more than 70 years old. The City undertook this effort to reduce future flooding […]

Otterdale Road Drainage Improvement Project

/in , , /by

In recent years, flooding along Otterdale Road has occurred during periods of heavy rainfall leaving neighborhoods completely landlocked. This Design Build project consists of three different locations associated with the stream crossings of Blackman Creek, Horsepen Creek, and Otterdale Branch with Otterdale Road where bridge replacements are being proposed. The purpose of this project is […]

Northwest Florida Base Level Engineering (BLE) Data Viewer: Providing Online Access to Complex Data Rich Flood Hazard Information through a Simple Visualization Utility to Support Community Resilience Activities

/in , , /by

Base Level Engineering (BLE) flood models for 13 watersheds covering more than 11K square miles of the panhandle was developed for the Northwest Florida Water Management District (NWFWMD). These BLE processes followed large-scale, automated engineering methodologies to produce flood hazard information. The purpose of NWFMWD’s BLE project is to develop updated flood studies using high […]

Compound Urban Flooding: The Emerging Hazard for Large Metropolitan Areas Located Along Tidal Rivers

/in , , /by

Compound floods from the co-occurrence of multiple flood drivers like riverine flow, storm surges, sea-level rise, and extreme rainfall have impacted several cities across the United States (US) in recent years. Metropolitan areas located in the coastal regions of the US have become increasingly vulnerable to such flooding conditions due to their exposure to multiple […]
