<br />Approach <br /> <br />This flood-hydrology study supplemented the existing study of flood <br /> <br />hydrology of foothills and mountains by Jarrett and Costa (1983) with: <br /> <br />(1) Onsite paleoflood investigations in the Big Thompson River basin and <br /> <br />surrounding river basins, (2) a new index of the contributing drainage to <br /> <br />flood runoff that indicates the trends based on elevation, (3) computa- <br /> <br />tion of regional rainfall flood-frequency relations, (4) incorporation of <br /> <br />paleoflood data into site and regional flood-frequency relations, (5) a <br /> <br />comparison of the regional flood-frequency relations to PMF estimates for <br /> <br />the selected sites, (6) demonstration of the impact of these flood- <br /> <br />frequency relations on design of structures and use of the flood plain, and <br /> <br />(7) an indication of future research needs. <br /> <br />/tJ <br /> <br />
