<br />Research and lechnology Ifansfcr ~eds arc described for Sleep stream
<br />channels and chules. Ileralive processes are presented for design and construction
<br />uf bouldery channels and chulcs and lhe need for avoidance of boaling hazards al
<br />grade chmrol SlfuClurcs.
<br />
<br />hurnduclion
<br />
<br />Consuhing engineers arc increasingl)' called upon 10 modify or relocate steep
<br />houldery stream channels and 10 construct whilC\\alCr chules 10 make grade cUlUrul
<br />slruclur~s s~fe for recrcalional boaters. The work Iypically musl meel llood comrol,
<br />hydraulic, Ylsual, recreational, safclY and environmental objeclives. Sleep channel
<br />.alld chUle ~Iopcs. olten range from aboul 0,01100.15 m/m (1.010 IS percclll), The
<br />l'haraClensllcs ollurbuleul How caused by low head drops and sleep chules can result
<br />III submerged hydraulic. jumps, r.everse rollers and adverse wave formal ion. Designs
<br />wlllch are 5aUShal'lory lor Ihe pomary purpose of a structure can produce hil1.ardous
<br />hydraulics and shuuld be avoided for public safety purposes (Davis and George, 1985:
<br />Wheal. 19K4).
