I am proposing to construct a temporary crossing across a wide ditch using 12" x 12" oak timbers. Four 20' long timbers are bolted together, similar to a crane mat. I am proposing to place a set of them from top of bank to top of bank to form a 8' wide deck. The load will be a 35,000 lbs 3 axle...
Greetings All,
I am a still a new user to the SWMM universe. Let me give you all the setup. I am designing the hydraulics for a small decentralized wastewater system that serves about 5 4-bedroom homes. The effluent flows into a 3000 gallon wet well where two same sized alternating pumps need...
I am trying to evaluate the soil loss in a agricultural watershed. The drawback to using RUSLE is that the length cannot exceed 1000 feet. Is there another method to estimating soil loss in a medium size watershed?
Working on a minor bank stabilization project that will consist of 3:1 slopes in hydraulic conditions. The banks will be approximatley 6 feet high. Seeking a single fabric that will provide both strength and hold back finer soils. I do not want to install two fabrics, I want to keep the cost...
What information would I need to gather in creating a rough lake level outlet into a county drain? What chacteristics would I need to know of the lake watershed? I know that the Dept. of Natural Resources and Environment (DNRE) has the final judgement.
Looking for a good design procedure to use when designing point source discharge from a site. Does anybody know of a nice easy to understand step by step procedure???
Even if anyone knows of a book.
We have a sedimention problem in a large network of county drains that outlets to a large lake. The lake is filling up slowly with sediment. We are trying to pin point the locations of the highest sediment by using a flow-meter, rain guage, and taking samples and having them anaylized for...
I have a land developer who wants to put in a properly engineered privacy berm between his subdivision and the neighbooring subdivision. He wants it around 9' tall. What are the standard slopes of a berm? Neglecting soil type. I am looking for the average slope steepness.
