Members of our North Texas Stormwater Group toured Arlington project sites to check on their progress this month. 

They toured a site by golf cart, checking on Village Creek erosion repairs throughout the Lake Arlington Golf Course. Freese and Nichols provided hydrologic and hydraulic modeling, stream geomorphological assessment and design services for storm drainage and erosion improvements to alleviate erosion throughout the sites. Improvements included about 850 feet of low maintenance, stable channel solutions and water line rehabilitation suspended from two golf cart path...

Freese and Nichols was contracted by the City of Arlington to formulate and design drainage improvements to alleviate the repetitive flooding of approximately 30 residential structures in the Green Meadows subdivision. The flood prone homes are located in a low-lying area which is adjacent to an existing undersized channel.

The project started in 2008 with a dynamic hydraulic modeling study and alternatives analysis. Several public meetings as well as significant public...

How Does It Work?
Generally, a 1-D hydraulic engine is used to model flow through storm sewers or channels, and the 2-D hydraulic engine is used to model the overland flow that occurs when the drainage system capacity is exceeded. However, the results from a 2-D model are only as good as the data used to build the surface model. So, the first requirement for 2-D modeling is an accurate surface model that represents the ground surface. If possible, the surface model should be built with breaklines that represent physical features such as curbs, walls, or changes in...
