EROSION-PROOFING DRAINAGE CHANNELS

METHODS OF IMPROVING OLD DRAINAGE CHANNELS AND BUILDING NEW ONES ARE DISCUSSED. LINING WITH GRASS IS SUPERIOR FROM ALMOST EVERY VIEWPOINT. WHERE CONDITIONS ARE OTHERWISE FAVORABLE FOR GRASS, BUT AVERAGE SLOPES ARE TOO GREAT, CONCRETE DROP STRUCTURES CAN BE USED AT NECESSARY INTERVALS. WITH THEIR UPSTREAM ENDS ANCHORED, ROCK SAUSAGES CAN BE USED WHERE CHANNEL SLOPE IS AS GREAT AS 50 PERCENT. FOR SLOPES LESS THAN 10 PERCENT, A LOOSE ROCK LINING CAN BE USED UNLESS THE SIZE REQUIRED IS TOO LARGE. FINE-MATERIAL WASH FROM BENEATH ROCKS CAN BE PREVENTED BY REVERSE-FILTER INSTALLATION.
