Introduction The field area was easily accessible by local transport or by own transport facility and we went there through our university bus. On very first day we travelled from Lahore to Abbottabad. We did field work in Harno Area (Abbottabad - Nathiagali Road), Sogri Oil well, Oghi-Khaki Road and Tarbela Dam. Physiography of the Area Hazara is a region of the Khyber Pakhtunkhwa province of Pakistan. It comprises six districts: Abbottabad District, Battagram District, Haripur District, Kohistan District, Mansehra District and now, since 28 January 2011, the new Tor Ghar District. It is a region that has many languages and ethnicities.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
