For the depth of a valley I could use the watershed analyses and subtract the DEM-Height of a river basin from the DEM-Height of its watershed-area which results in the height-difference.<br/></div><div>But I have no idea how to analyze if the valley has a width of at least 100 meters.<br/></div><div>Can somebody give me a hint?<br/></div><div><br/></div><div><br/></div><div>Thanks,<br/></div><div><br/></div><div>Kerstin<br/></div></div> <br><br><table cellpadding="0" cellspacing="0" border="0"><tr><td style="font-family:verdana; font-size:12px; line-height:17px;border-top:1px solid #000000">Ihr WEB.D
