This is a lot easier in metric but i divided my area into 1 m squares. Made myself a water level and got an assistant ot draw the whole lot out on a piece of graph paper and took a reading at every intersection and transferred the lot to graph paper and i made my plans from there. Don't forget to double the variations in your water levels, as they work half at each end of your water level. ie if youhave a variationof  2 cms one end will go up 1 cm and theother down 1 cm. Now comes in the bit where metric is so good. All horizontal measurements are made in metres and vertical ones in centimetres; divide the vertical by the horizontal and all results will be in percentage of grade. if you would like to see a picture of my water level send me your email adressa dn i wilsend you a copy of a photo and advice as to how to make one!
