Abstract

CAMPOS-ARANDA, D.F.. Probabilistic Estimation of Suspenden Sediment Volume in Watersheds Without Hydrometric Data of the Hydrological Region No. 10 (Sinaloa). Ing. invest. y tecnol. [online]. 2009, vol.10, n.3, pp.227-236. ISSN 2594-0732.

Firstly three actions are proposed to mitigate the negative effects of climatic change in the hydrological design. Besides is pointed out the utility of regional analysis of hydrological data to obtain more reliable formulae and procedures for estimating design values in water sheds with out hydrometric data. Next, the suspended sediment data available in Hydrological Region number 10 (Sinaloa) is described and the utilized data is cited. The homogeneity of that region was accepted through the relation between water shed area and mean annual suspended sediment volume. Late three regional methods are described and applied, these are: (1) the station-year method, (2) the regional probability weighted moments (PWM) method and (3) the weighted PWM method. Next, the numerical application for sediment capacity estimation in three reservoirs of the region is described. Lastly conclusions are formulated which pointed out the advantages of the proposal approach.

Keywords : Sediment; regional analysis; probability weighted moments; GVE distribution.
