We present 'bAd Calculator', a new software developed in Visual Basic programme which can be applied for analyses of various drainage basin parameters, directional aspects, etc. The graphical user interface of bAd Calculator can be used for several applications such as determination of bearing and azimuth of linear features and their representation in rose diagram. Various drainage basin parameters such as drainage density (Dd), stream frequency (Fs), bifurcation ratio (Rb), mean bifurcation ratio (Rbm), steam length ratio (RI), drainage texture (T), texture ratio (Rt), dissection index (DI), length of overland flow (Lg), RHO coefficient, circulatory ratio (Rc), hypsometric integral (HI), etc. can be easily calculated by using the software. The software provides a point-and-click technique for rapid acquisition of watershed parameters with user-specified grids/sub-basins. (C) 2012 Elsevier Ltd. All rights reserved.
