Bourn Brook - We do field work because we need to learn the skills to do the practical experience.

Bourn Brook – Introduction

We do field work be cause we need to learn the skills to do the practical experience. We visited the river because we need to do the research of the river. We need to know how deep, width, velocity, erosion, bed load and sinuosity of the river. We also collect different shape of stone.

Bourn Brook join to R.Cam, R.Rhee and Granta. The river system is in Cambridge. It is rural catchments. There have much wildlife like roach, pike, cow, perch and carp. The river begins north east of Henlow, where springs rise from the underlying chalk aquifer. This water-bearing chalk is the dominant geological factor in the area south and east of Cambridge, providing a natural base flow to the river. Rain percolates through the porous rock, emerging at the surface when the hard bands within prevent further downward penetration.
