Western Dam Engineering <br /> Technical Note <br /> <br /> May 2016 <br /> <br />7 <br />Geotechnical Applications <br />GeoID (Engineer Geology & GIS Lab. SNU, iOS, $5.99): <br />GeoID is a useful tool for measuring and analyzing any <br />geological structure. The app uses a built in <br />magnetometer and accelerometer to assess direction <br />and orientation and gives the Latitude, Longitude, date <br />and time of each measurement taken. A substitute for <br />the typical Brunton compass, this app can accurately <br />and rapidly measure multiple strike and dip <br />orientations of joints, faults and bedding planes, saving <br />lots of time when field mapping. This application <br />includes a geological compass, stereographic <br />projection, instability analysis, and wireless data <br />sharing when connected online. The app is easy to use <br />and does not require cellular data usage to function. <br />Soil Classify (Mendota Engineer, iOS, $3.99): <br />Soil Classify is an app that can be used to instantly <br />classify soil per AASHTO and USCS standards without <br />the need to look up the corresponding reference <br />charts. Each system uses soil gradation (sieve data) and <br />plasticity (Atterberg limits) to classify the soil into <br />standardized descriptions. <br />pLog (Dataforensics, LLC, Android, License Fees Vary): <br />The pLog app is a tablet application from <br />Dataforensics, LLC developed for geotechnical and <br />environmental site investigation data collection. The <br />app uses integrated GPS for recording hole location <br />and real time data sharing when connected online. The <br />app provides a graphical preview of the log right in the <br />field for easier visualization as the investigation is <br />happening. One of the best advantages of the mobile <br />app is the huge time saver it offers by allowing direct <br />data entry in the field, which can then be exported in <br />CSV or DAT format directly into any software used for <br />drafting boring logs including gINT, LogPlot, HoleBase, <br />ESdat, even Excel, for easy and efficient creation of <br />subsurface logs. It is available on Android tablets with <br />varying license fees based on the quantity purchased. <br />Hydraulics/Hydrology Applications <br />Flo Hydraulic Calculator (Dana Shakiba, <br />iOS, $1.99, Data Required/Standalone): <br />The Flo Hydraulic Calculator from developer Dana <br />Shakiba is a versatile, comprehensive, and easy-to-use <br />hydraulic analysis app that performs flow calculations <br />for several different hydraulic structure types including <br />pipes, channels, weirs, and orifices. The user can <br />choose which parameter to solve for; compute flow for <br />a given geometry or compute required geometry (pipe <br />diameter, channel width, channel depth, or slope) for a <br />target flow. The interface is intuitive, easy to <br />manipulate, and color coding helps guide the user to <br />the required input versus computed parameters. The <br />app has a comprehensive and easy-to-understand <br />information tab that contains quick how-to <br />explanations as well as a thorough database of various <br />required coefficients, such as Manning roughness and <br />weir coefficients. The information tab also provides a <br />quick reference to the relevant equations being used <br />for the selected computation. Calculations are based <br />on the Federal Highway Administration's Hydraulic <br />Engineering Circular No. 22 (HEC-22) and the United <br />States Bureau of Reclamation Water Measurement <br />Manual. This is a handy tool to have, especially when <br />in the field for a quick estimate of toe drain, seepage <br />weir, or conveyance channel flows. <br />Additionally, Android users have a few choices such as <br />Hydraulics Calculator ($4.00) or Channel Hydraulic <br />Calculator and Pipe Hydraulic Calculator (the last two <br />are free). <br />
