Hydrologic design considerations Permeable pavement is subject to the following design considerations, including benefits and constraints. Available space – A significant advantage of permeable pavement is its ability to combine detention/ infiltration and pavement, thereby reducing or eliminating land required for detention facilities. This is especially important in urban areas with high land prices and highly developed sites with little or no space for stormwater detention. Soils – Soil conditions and infiltration rates determine the use of an  underdrain . ( NRCS   Hydrologic Soil Group  (HSG) C or D soils usually require an underdrain, whereas HSG A and B soils often do not.) Designers should evaluate existing soil properties during initial site layout with the goal of configuring permeable pavement that conserves and protects soils with the highest infiltration rates. In particular, areas of HSG A or B soils shown on soil surveys should be considered as pri...

The water treatment plant will treat raw water coming through 26.5 Km tunnel from Melamchi River for the Melamchi water supply project. The ultimate capacity of the water treatment plant will be 510 mld. The plant will be developed in three phases, each of 170 Ml/d. The second stage will be accomplished by duplicating the major facilities of the initial phase, and the third phase will comprise mainly performance enhancements and increased design loading on the facilities constructed under phases 1 and 2. As the first phase of WTP project, the detailed design of the WTP capacity will be done for 170 mld with provision of the future expansion. The design of phase 1 allows for the complete development of the site over the three phases, and some facilities are, therefore, sized for the ultimate capacity. The treated water will then be served to the 1.1 million population of Kathmandu Valley. The water treatment plant is to be located near Mahankal, a village on the left bank of the...

Hello everyone, I am a civil engineer from thapathali engineering campus(TU). Here are the list of documents which an engineer/engineering student (final year) must go through if he/she wants to work in reconstruction project either in government job or through NGO/INGOs. SMM 1.1 House Models and related documents can be downloaded from here: 1)   House Models Volume I 2)  House Models Volume 3)   Engineers Trainig I 4)  Engineers Training II 5)  Mason training Thank you !!

SURVEY CAMP KIRTIPUR Before Survey Camp 1) Carry your laptop. Don't fear of losing and breaking or anything like that. 2) Install Microsoft Office (Excel is needed) , Autocad and DTM ( Digital Terrain Modeling) in your laptop. (GIS is optional ) 3) Learn the basic of Excel like addition, substraction, multiplication ,division etc. by putting formulas. Also, learn the conversion of Degree, Minute and Second in excel. 4) Carry some painkiller, water bottle and torch light. In Survey Camp Traversing 1) In traversing, don't make so many legs. Around 18-19 legs are sufficient. 2) Please make the calulation of the data properly. Try to do all the table calculation in Excel. 3) Don't try to cheat while making calculation and plotting. You will have to do again if the legs are not oriented perfectly. Fly levelling Fly levelling of around 1-2 km should be done making closed loops. Also, fly levelling should be done to transfer the RL to each major and minor ...

The position or the layout of the center line of the highway on the ground is called the alignment. The horizontal alignment includes the straight path, the horizontal deviations and curves.  Changes in gradient and vertical curves are covered under vertical alignment of roads. Highway Leading through mountains towards National Park Canada A new road should be aligned very carefully as improper alignment would result in one or more of the following disadvantages :- # Increase in construction cost # Increase in maintenance cost # Increase in vehicle operation cost # Increase in accident rate Once the road is aligned and constructed, it is not easy to change the alignment due to increase in cost of adjoining land and construction of costly structures by the road side. Hence the importance of careful considerations while finalizing the alignment of a new road need not be over emphasized. Stability  While aligning hill roads, special care should be take...

Rain Water Harvesting in Thapathali Campus Introduction:                                         Water supply problem is one of the major issues at urbanized areas of our country due to over population concentrated at major cities of Nepal and especially at Kathmandu valley including different government Campus. Due to which, students are facing directly or indirectly trouble in consumption of water. For this, we can take an example of Thapathali Campus where there is no proper water supply in toilet, workshop, laboratories etc. Most importantly, there is no source of safe drinking water as well. Therefore, Rain Water Harvesting system is the reliable solution regarding this problem, where we can store rainwater in container, tank by sand filtration process and we can use it for various purposes...
